How to install a sink on a kitchen countertop? This process is considered quite labor-intensive and complex, but it is quite possible to do it yourself. To understand how to embed a sink into a countertop with your own hands, you need to carefully study the instructions and follow the recommendations of experts.
Variety of models by design
There are several ways to install a kitchen sink into a countertop. First, it is important to take the measurements correctly. Otherwise, there is a risk of damaging the furniture and installing the product unevenly.
Under-desk models
Installing a sink under the countertop is very convenient. In addition, under-table models look stylish. You can install a kitchen sink in a countertop if it is made of stone or plastic. The fact is that non-moisture resistant materials will lead to failure of the table. How to install a sink under a countertop? This is done in such a way that the product is below the table level. In this case, water will constantly fall on the cut in the table.
This is why moisture-resistant materials such as stone or plastic are ideal for this installation method.
Built-in models
How to install a sink into a countertop so that it is level with the table? This product is called mortise. How to install a sink in the kitchen? They are installed in a hole in the table, which is cut out with a special tool. The work must be done very carefully and accurately. Otherwise, the structure may not stand up straight.
Overhead models
Most in a simple way is to install a sink in the countertop in the kitchen above the table level. Installation requires the least amount of tools. Installing a sink on a countertop using an overhead method is possible at home. This does not require specialists.
Manufacturing materials, price difference
The materials from which products are made vary. They differ appearance, price and have their advantages and disadvantages. The most commonly used materials: stainless steel, artificial stone, plastic.
Models made of stone (artificial and natural)
The stone sink in the countertop looks beautiful. Recently their popularity has increased. This is due to the fact that products from artificial stone have a number of advantages. Among them:
Moisture resistance
No noise
Environmental friendliness of the material
Wide range of products
Resistance to temperature changes
Long service life
The main disadvantage is high price per product. Such products will cost much more than stainless steel sinks. The large mass of the products does not allow you to install them yourself.
Stainless steel products
Shells from of stainless steel are in great demand. This is explained affordable price, practicality and wide range goods. The disadvantage of stainless steel is its high noise level and unreliable fastening of the mixer. This applies to thin material.
Ceramic models
Lately everyone has been deciding to install a ceramic sink into the countertop. more people. Ceramic models They will cost more, but they look very impressive. The advantage of these products is their durability, variety of shapes and colors. Ceramic models are heavy, so it is unlikely that you will be able to install them yourself.
Overlay installation basics
How to integrate a sink into a kitchen countertop? For this, special fasteners are used. They usually come with a sink. 4-5 fasteners per product are enough.
Installing a sink into a countertop yourself looks like this:
First, make the necessary notes. To do this, attach fasteners to inside table and take notes
To prevent the table from being damaged by water, its ends are covered with sealant.
If necessary, remove excess sealant
The last stage is connecting to the sewerage and water supply system
Flush installation
Installing a built-in sink into a countertop is somewhat more complicated than installing a countertop sink. Installing a sink into a kitchen consists of several stages:
Make the necessary measurements
Cutting out a hole
Install the sink
Fasten the product
Self-installation of a built-in sink into a countertop without the help of professionals is quite possible. To do this, you need to follow the following instructions.
How to cut (cut) a hole in a table
How to make a cutout in the countertop for a sink? First you need to determine the cutting line. To do this, the product is turned upside down and placed on the table. When the sink is installed on the countertop, you need to mark it along the contour with a pencil. Next, the undermount sink is installed as follows:
You need to make a hole along the line marked with a pencil. To do this, first drill in the corners with a drill
After this, the outline is cut out with a jigsaw. It is necessary to cut from the front side of the table, otherwise chips may form on the surface
Sealing the sink in the countertop. To protect the table from water, its edges are coated with sealant
Mortise mounting method
How to secure drop-in sink on the countertop? The sink is attached to the table using clamps. These items are usually included with the sink. Excess sealant is carefully removed. At the end, communications are connected.
How to fix corner, round and granite sinks
There are sinks different color, made from different materials. In addition, their shape is also varied. They can be round, square, or unusual designer ones. The method of fastening them is somewhat different from each other.
Round model fastener
It is recommended to install a round sink in the kitchen if the room area is small sizes. The round model will save space and increase its functionality. Such products generally have a deep and large thicket. Circle-shaped sinks fit perfectly into modern furniture and in corner kitchen units. Installation round sink usually occurs in a mortise manner.
How to install a sink in the kitchen round shape? This is done like this:
The sink is placed on the table
Draw around the edges with a pencil
Sawed along the lines
The edges are treated with sealant
The sink is installed and fixed
Installation of a granite model (video example of installing a black granite sink)
Granite products can be of various shapes and colors. They also differ in size. It is recommended to take into account the dimensions kitchen furniture and shells so that the overall picture creates a beautiful and harmonious look. The placement of a corner sink is no different from a round model. Granite sinks are installed in three ways, including:
Integrated
Overhead
With the overhead method, the sink is installed on top of the table and secured with special clips. The mortise method involves cutting out a hole into which a granite product is placed. In the latter method, the countertop and sink are one piece.
Thus, the sink can be placed in the countertop independently in several ways. Some models are difficult to install without the help of a professional.
The times when the kitchen sink was a metal sink screwed to the wall and equipped with two taps are long gone. Today design features allow you to place it directly on the countertop. Moreover, it can be overhead or built-in. In the latter case, its parts will not be visible from above on the tabletop. Let's consider the first option today, since it is most suitable for self-installation.
Learn more about installation methods
As we already said, installation kitchen sink implies two options:
| Overhead |
The disadvantage is the humidity that constantly forms between the unit with the sink and the adjacent cabinets. |
| Mortise | Installation is much more complicated and it will be very difficult to do it yourself. This method is favored by a variety of shapes and types of sinks. For example, you can install models made of stone, plastic, stainless steel, copper, bronze, as well as round, rectangular, corner, asymmetrical sinks. |
There are different ways to embed a sink into a countertop; in this case, not only your desire plays a role, but also the design capabilities of the kit.
Therefore, it could be relative to the surface:
- flush with it;
- slightly above or below it.
Advice: when purchasing a model you like, we recommend that you immediately clarify the location, as well as what fasteners you need to use for it.
Please refer to the last point Special attention, since often the quality of the bowl is significantly superior to the proposed mounts, so it is worth choosing the appropriate ones.
Preparation for installation
Installing a sink is the last or final stage of assembling the water use unit in the kitchen.
Therefore, you should prepare for it thoroughly:
- You must first supply water to the installation site.
- You should also take care of the tools, where the main role is played by the jigsaw. You can buy it or rent it for a few days, but buy new files for it so as not to experience discomfort while working.
Advice: the price of even the most expensive ones is from the most famous brands, for example, Bosh, will not hit your budget, but the process of cutting out space for the sink will go like clockwork.
- Don't forget to also buy silicone transparent sealant, and it’s better not to pin your hopes on the self-adhesive foam rubber edging offered in the kit. It is bad because moisture will gradually accumulate in it, which will soon begin to emit an unpleasant odor, while simultaneously destroying the countertop under the overhead sink. We simply recommend not using it at work.
- At the time of buying kitchen sink Find out if it comes with a template or stencil that will help you cut it into the tabletop. Usually it comes as a package, so don’t rush to tear it apart, look to see if there is a design on the cardboard. If not, then we will tell you below how to mark a place on the surface by applying a sink to it.
How to cut a sink into a countertop without damaging its edges - secure the cutting area from below with tape
- The siphon, water supply and drainage pipes are not included in the washing kit or are very rare, so do not forget to purchase them additionally.
Advice: do not fix the countertop to the cabinet of the kitchen unit, if possible, in this case it will be easier to work with an overhead sink, but in the case of a built-in sink, this is a prerequisite.
Making space for an overhead sink
It makes no difference what configuration the sink will be, the instructions will be exactly the same:
- Before cutting out a sink in the countertop, choose a place for it.
In doing so, make sure that:
- there was free access to water and sewer pipes;
- there was a distance of at least 60 mm from the edge, otherwise thin layer can be broken;
- were not located under the countertop bearing structures cabinets, they cannot be cut during operation, otherwise the reliability of the headset will decrease.
Tip: secure the cut area with masking tape from below so that when you approach the end of the saw, the material does not fall and damage the tabletop, or use “the help of a friend” to support it from below at this moment.
Take an electric drill with a Ø 10 mm drill and drill a hole in the tabletop at the inner mark to insert a jigsaw file into it. Then slowly and carefully cut along the line.
The technology of installing a sink into a countertop is not an easy process and is quite labor-intensive. If the installation conditions are not met, you can not only reject an expensive plumbing fixture, but also irreversibly damage the surface of the countertop. This can be avoided if you follow the rules and listen to the recommendations of specialists.
The main task when installing a sink into a kitchen cabinet countertop is to comply geometric dimensions mounting hole.
But, in addition to this, at the first stage of planning the work, it is necessary to choose the installation method.
It depends on the design of the sink and is currently distinguished following types installation:
- the upper plane of the sides of the sink is below the level of the countertop. Externally this method The installation looks attractive and strict. It is often used for expensive kitchen sets, since the installation technology is difficult. To implement it, you need a special tool and washing machine. specific design. The cut edges are treated with water-repellent material.
- insert at the level of the tabletop plane. For this type of installation it is important preliminary preparation tabletop surfaces. In the area where the sides of the sink are attached to the countertop, use special tool make recesses that are equal to the thickness of the sides of the sink. The work is painstaking and precise. The slightest mistake or misalignment will change the plane and the entire structure will lie unevenly.

Photo: sink above countertop level How to do it at home
As an example, we will consider the most common option - installing a mortise sink above the level of a countertop made of chipboard.
All work is divided into the following stages:
- marking;
- cutting a hole;
- installation;
- sealing.
But before you start, you need to prepare the optimal set of tools and consumables.
Required Tools
Before starting work, the sink is equipped with fastening materials and is checked. In most cases, these are special clips that are mounted on the inner surface of the sink on one side, and on the cut end of the countertop on the other.
The kit should also include a tubular seal designed to seal the joint.
The minimum list of tools is a set of:
- construction pencil;
- measuring tool - tape measure, steel angle, level;
- drill or screwdriver (wood drill 12 mm);
Photo: screwdriver - set of screwdrivers – Phillips and slotted;
- sandpaper;
- jigsaw with a set of spare wood saws (fine-toothed, double row).
Photo: jigsaw with a set of spare wood saws - drywall or shoe knife;
- silicone;
- fastening tool – hardened wood screws.
The installation site must be cleared of foreign objects. Installation is best done on a tabletop that is not yet installed on the frame of the cabinet.
But even on an already assembled table, you can cut out the correct hole for the sink.
Performing markup
This procedure is designed for installing a standard rectangular sink. For round and corner structures there are certain specifics and differences in installation.
The process of marking the future cutting location occurs using the following technology:
- Using a pencil, draw two perpendicular lines. At the intersection of these segments there will be a drain;
- Having turned the sink over, place it on the countertop and mark the outer boundaries. In this case, it is necessary to take into account the offset of the edge of the tabletop relative to the level of the cabinet doors;
Photo: outline Important! The sink after installation should be inside the cabinet. Otherwise, it will interfere with the closing of the doors.
- Having measured the width of the side of the sink, the internal contour is drawn. It is along this that the cutting line will run. The width is individual for each sink, but usually it is within 12 mm;
Photo: marking the working building The end result should be a cutting outline,
Photo: cut outline After this, all dimensions are checked again and the process of cutting a hole in the tabletop begins.
Cutting a hole in the countertop
The process of cutting the hole is done using a jigsaw. Before marking and initial entry of the tool saw to the entire depth of the table top, it is necessary to make technological holes.
They are made using a drill (screwdriver) with a wood drill bit. The drilling location is the corners of the internal markings.
The corners should be located in the inner plane of the cutting area, their edges only touching the cutting line.

Photo: cutting out a hole Upon completion of the cut, the screws are removed, and the cutting part of the tabletop is removed from the main plane. The sink is pre-installed in the resulting hole, thereby checking its compliance with the dimensions of the plumbing fixture.
If after installation there is a slight play, it means the cutting process was successful. If installation is difficult, you should additionally process the cut edges of the tabletop with a jigsaw. After this, the ends are cleaned.
Photo: it is necessary to clean the ends of the cuts Slice processing
In the process of cutting a hole, irregularities, roughness and micro chips will form on the inside along the cutting line.
If you neglect their treatment, the following problems may arise during the use of the sink:
- it is almost impossible to achieve complete sealing of the unprotected part of the chipboard;
Moisture will enter this area of the countertop, which will lead to the activation of rotting processes and the formation of fungal plaque. Over time, the cut edge will become brittle, which may cause the sink level to fail.
- rotting of the countertop under the influence of moisture will quickly deteriorate its physical and aesthetic properties and will require replacement with a new one.
The end part of the cutout is sanded with fine-grain sandpaper.
After this, you can take 2 options for applying a protective waterproof layer:
- sealant treatment. It quickly isolates the entire cut area. For this, it is recommended to use high-quality material. However, it is not always possible to notice its absence in one or another part of the cut. Therefore, the amount of sealant on the surface should be in excess;
- PVA glue. A more reliable, but labor-intensive method. An evenly applied layer of glue will reliably protect the cut from moisture. But for final hardening you need to wait 30-50 minutes.

Securing the sink
Before installation, an adhesive-based tubular seal is attached to the inner mounting end of the sink.

Photo: final fixing This installation example is considered classic. But in addition to chipboard countertops and stainless steel sinks, there are products made from other materials.
Artificial stone countertops
Countertops made of artificial stone are more durable than their counterparts made of chipboard. However, the main problem is the installation of built-in kitchen appliances, in particular the sink.
In most cases, stone countertops are ordered with ready-made holes for a specific sink. But what to do if the countertop is already in place, but the sink has not yet been installed under it?
Photo: artificial stone sink The best and most reliable way is to take the tabletop to a specialized company, which will cut the required hole with a professional tool.
If you want to take a risk, then this work can be done using the technology described above, but instead of a jigsaw, take an angle grinder (“grinder”) and a disc for cutting diamond-coated concrete.
When cutting, there will be a large amount of dust, so it is best to carry out the work outside the living room.
Features of inserting round and corner sinks
Regardless of the shape of the sink, the entire installation process will be identical to that described above.
But for round and corner structures there are some features.
Photo: installing a round sink For a round sink:
- It is recommended to make several holes along the cutting line in increments of 7-10 cm. This will make the cutting procedure easier;
- Some models come with a cutting template. If it is not there, then you can make a template yourself.
Photo: cutout for a round sink cutout template For corner sink:
- since the angle of rotation of the cutting lines is less than 90°, for better passage of the jigsaw saw several holes are made - directly in the corner connection of the lines and at a distance of 2-3 mm from it.
Granite sink
Photo: granite sink Installation of a granite sink should only be carried out by professionals and using modern equipment.
The installation process itself is no different from installing a stainless steel sink and consists of the following steps:
- tabletop markings;
- hole cutout;
- installing a sink into a countertop. The junction between the granite sink and the countertop also needs to be sealed. The fastening elements are the same as in the standard designs described above.
The specificity of the installation is that there are no holes on the granite sink for installing a drain siphon and tap.
They are made using a drill with a special attachment. If you have no experience working with artificial stone, then the slightest mistake can lead to a defect in the sink and its failure.
Price
The cost of installation depends on the material of the countertop and sink. If the design is of a non-standard shape, this will increase the price.
The table shows approximate installation prices
Self-installation of a standard rectangular sink must be thought out at all stages of installation. This will help reduce the time it takes to carry out work, and will also significantly improve their quality.
Epochs change, and with them, life. Modern kitchen equipment differs significantly from the stereotypes that have developed over the years; only some accessories remain unchanged. Not a single kitchen is complete without a refrigerator, sink and stove, either now or several decades ago. One of the key parts of the work triangle is the sink. And if earlier it was, as a rule, an enameled overlay structure of white color, now the variety has increased significantly. Modern kitchen sinks are made from a variety of materials and have different shapes, sizes and design features. The owner may not always be able to install such elements. Features of different models, their advantages and disadvantages, as well as tips on how to embed a sink into a countertop - below.
Appearance of a kitchen sink, relevant several decades ago
Installing a sink with your own hands may involve different technologies. Let's look at the main design types of kitchen sinks.
A countertop kitchen sink can have up to two bowls
Types of kitchen sinks:
- Overhead models. This type is considered the most common due to its ease of installation. Even a beginner can handle installing an overhead sink. They are usually made of stainless steel and are generally rectangular in shape. Installed on top of a kitchen cabinet that does not have a countertop.
- Recessed sinks. Such accessories are installed in a prepared hole in the tabletop, which must be cut exactly to the size of the structure. The sink is immersed in the hole treated with sealant and fixed with fasteners.
- Under-table products. Their installation method is similar to the previous one: the sink is installed in a hole cut in the countertop. The only difference is that not all countertop materials can provide an integrated type of installation, and the cuts of the hole must be processed carefully.
An undercounter or integrated kitchen sink requires a complex type of installation and generally can only be done in a factory setting
One of the important criteria for choosing a sink is its depth. Sink too deep ( 20 cm or more) is not convenient to use, as it forces you to bend over a lot. Shallow bowl ( up to 15 cm) is bad because water tapping on it from an open tap will splash around the entire working area.
The choice of mixer height depends to a large extent on the depth of the bowl. For example, for a deep sink it is better not to choose a faucet with a high spout, as well as for a shallow one with a low one. This all affects ease of use.
A high faucet over a deep sink is inconvenient because the water pouring out of it will splash heavily around
Of all the types of sinks listed above, today's users mostly choose the mortise type. Such sinks are affordable, have a comfortable depth and, importantly, a modern appearance.

Why mortise: reasons for choice
The aesthetic component of a kitchen sink is far from the only criterion for choosing a mortise design. Why do modern consumers love this type of sink so much?
A mortise sink can have either a standard siphon or an expanded hole, which is initially provided for installing a disposer
Design advantages:
- Possibility of installation anywhere. By purchasing a mortise-type product, you do not depend on the cabinet installed under it. The bowl can be embedded in any place, the main thing is to provide communications.
- Lack of moisture. When using an overhead structure, it is impossible to hermetically seal the joints between the modules, the washing block and the walls. Almost always, water flows into the resulting cracks, which is fraught with rapid destruction of furniture and dampness on the walls.
- The choice of mortise sinks is much wider than in the case of overhead sinks. They can have different shapes, functionality, number of bowls, materials of manufacture and sets of additional accessories.
- Modern appearance combined with affordability. The mortise accessory looks almost like an integrated one, but costs much less.
A built-in sink may include removable cutting boards, grids for washing food and other accessories.
Types of kitchen sinks by shape
The shape of the kitchen sink depends on the number of bowls, type and installation location.
Kitchen units are:
- square;
- rectangular;
- round;
- triangular;
- complex shape.
Kitchen sinks of complex shape are made exclusively to order and usually have an under-counter or integrated type of installation.
Kitchen sink designs can have not only different shapes, but also the number of bowls. Standard models are usually equipped with one or two bowls, while atypical models can have up to four.
An example of a round sink with four bowls, a fruit rack and a cutting board
Video - DIY sink and faucet installation
Types of sinks by material of manufacture
If previously washing accessories for the kitchen were traditionally made only of iron, cast iron or stainless steel, then the modern choice of materials is much wider.
Artificial stone sinks are the second most popular after stainless steel sinks
So, today on the market you can find shells from:
- natural and artificial stone;
- ceramics;
- natural wood;
- earthenware;
- of stainless steel;
- enameled metal;
- glass
Kitchen sink made of earthenware or ceramics
The easiest to install are stainless steel sinks. Glass sinks are difficult to maintain, while earthenware sinks are finicky to use. Sinks made of artificial stone require regular cleaning, but few people can afford granite ones.
Installation of a mortise sink: step-by-step instructions
The kitchen sink installation process is divided into several stages. Let's consider installing a mortise sink into a countertop using the example of a stainless steel product and an MDF surface.
Step 1. Preparation.
The key to successful work is the correct preparation of materials, tools and everything necessary. When purchasing a sink, do not forget to check its packaging to ensure it matches the description. Often, small fasteners can get lost during transportation and the packaging is damaged. Check if there are enough clips, if there is a seal, etc.
Don’t rush to throw away the included sink template. This is a great help when marking the surface
Tools for installing the sink we will need:
- pencil or marker;
- roulette;
- level;
- sandpaper;
- ruler;
- drill;
- jigsaw;
- screwdriver;
- adjustable wrench;
- a Phillips-type screwdriver or a set of cue balls for a screwdriver.
In addition to the sink and its accessories, you will definitely need colorless silicone sealant and hardware (you can never have too many of them).
Step 2. Applying markings.
If there is a template included in the kit, marking is done quite simply: cut out the outer contour and inner diameter of the sink from cardboard (on which everything is drawn in full accordance with the dimensions), apply it to the countertop in the right place and trace it with a pencil. To prevent the template from sliding on the glossy tabletop, it can be attached in some places with tape, as shown in the picture below.
Marking on the tabletop using a cardboard template
If there is no template, the markup will be somewhat more difficult to complete. First you need to mark the edges of the sink.
Remember! The sink should not be closer to the edge of the countertop than 10-15 cm.
Next, turn the sink upside down with the bowl, lay it on the table the way it will be installed, align it parallel to the edges of the table and trace the outer contour. For ease of operation, the sink can be secured in some places with tape.
When tracing the outline, do not rush or fuss. The correct installation of the device will depend on the markings performed.
We measure the distance from the outer edge to the bowl, remove the sink from the markings and mark a cutting line inside the drawn contour.
Step 3. Hole in the countertop.
Using an electric drill, we make several holes in a row along the cutting line. The width of the resulting gap should be such that a jigsaw can easily fit into it. Next, take a jigsaw and carefully follow the cut line, slowly and without fussing.
Prices for popular models of jigsaws
Jigsaw
To prevent the cut-out part of the tabletop from falling with a crash to the bottom of the module, secure it in several places with self-tapping screws.
Important! Never turn the tabletop over. Make the cut only from the front side to avoid chipping the enamel.
When the hole is completely cut, the screws are removed and the cut is cleaned of dust and sawdust. A “fitting” is carried out: the shell is first placed in the prepared hole, it is checked that it fits normally, does not “walk” and does not cling to anything.
If washing is difficult in some place, straighten the cut with a jigsaw
Step 4. Processing the cut.
Any particle board absorbs moisture well, so the cut area must be carefully sealed with an antifungal compound and sealed with the sealing tape that comes with the sink. Before processing, all roughness must be treated with fine sandpaper. Proper protection of the cut from getting wet will prevent rotting of the tabletop material and its rapid destruction.
Instead of antifungal compounds, you can use PVA glue diluted with water in a ratio of 2:1 to process the end cut. After application, the glue must dry
If chips appear on the front side of the tabletop where the plastic is cut during the cutting process, treat them with silicone sealant. Only after this can the end cut be glued with the included foam sealant. We also seal the side of the sink along the edge with sealing tape.
Step 5. Attaching the sink to the countertop.
We treat the cut of the sink with silicone sealant and attach clips to the sides of the bowl from the inside. We insert the plumbing fixture into its permanent place and press it well. 10-15 seconds. After this, let go, check the level, wipe off the excess substance with a soft cloth and wait for the sealant to completely set, fixing the sink in the groove.
It is better to secure the sink with clips after the sealant has set. This method ensures that the sink will not slip off and, as a result, will not be attached incorrectly.
Step 6. Connecting communications.
How a chipboard countertop is constructed
First, install the faucet and fasten it with a fixing screw. We connect the hoses leading from the tap to the water supply system. When fixing the faucet to the sink, do not forget to use a rubber seal.
On a note. It is better to assemble the mixer before installing the sink by screwing water hoses to it. It will also be more convenient to immediately fix it on the bowl until it is fixed on the countertop.
To ensure the strength of all connections when installing the pipeline, use fum tape.
Do not forget to treat all connections with silicone sealant before installing the siphon and tap.

Upon completion of work, do not forget to check the mixer and sewer system for leaks.

Features of working with artificial stone
As a rule, stone countertops are made to order in accordance with the preferences of the buyer, and the hole for installing a sink is provided in advance. But there are also exceptional cases when, for example, it was initially planned to install an overhead sink in the kitchen, and the countertop had to be solid.
An artificial stone countertop is quite difficult to process. It must be handled with care as the material is fragile
For such work, it is better to invite a qualified specialist with a professional tool, who will make a hole of the required diameter with a correctly processed cut and install the sink in accordance with all requirements.
If you decide to make a hole for installing a sink on your own, saving on labor costs, instead of a jigsaw, it is better to take a grinder and, when cutting, protect your eyes and respiratory tract from stone dust. The work algorithm is not much different from installing a sink in an MDF countertop.
Note. To work with artificial stone, you need to install a concrete disc with laser chips on the grinder.
Features of installing sinks of different shapes and materials
In the example above, we looked at the installation of a round or oval sink. But what about other products?
Corner sinks
When installing a corner sink, the main nuance is cutting out an even corner. To do this, so that the jigsaw can pass through the tabletop easily, several holes in a row are made in the corners using an electric drill, then they are combined together.
The presence of technological cuts greatly simplifies cutting a hole in the countertop for a sink of atypical shape
Also, when installing a corner sink, it is important that the corner of the sink clearly coincides with the line connecting the outer and inner corners of the cabinet.

Square sinks
When installing a square sink, draw a line on the countertop parallel to the outer edge. The width of the product is retreated from it and another line is drawn. In the same way, measure and mark two perpendicular lines, completely tracing the contour of the sink. Opposite corners are connected by lines; the siphon will be located at the intersection of these lines.
Holes for a jigsaw when installing a square sink are made in the corners of the drawing
Granite products
The design of sinks made of natural stone does not provide technological holes for installing a drain and mixer. And if the mixer can be mounted separately on the wall or on the countertop, then the sink simply cannot do without a siphon. It is very difficult to make such a cut in a stone product yourself without experience. An electric drill with a diamond attachment is used to make such holes.
If you have a granite sink, it is better to entrust its installation to professionals, since without experience, such an expensive product can be quite easily damaged

For the most part, ceramic kitchen sinks are made mainly in a combined version - part of the sink is a countertop, and part is mounted in the countertop, like a mortise model.
Ceramic, like natural stone, has quite an impressive weight, so such sinks require a very durable cabinet and a strong countertop
Ceramic sinks are attached using a combined method for a more durable fixation. Along with the use of sealant or adhesive, mechanical fastening parts are also used. You can also prepare the internal supporting structure yourself. To secure the washing niche, a structure is assembled from wooden blocks treated with antiseptic compounds.
When making a sink hole yourself, measure the sink several times before you start cutting. It is better to make sure that your actions are correct at the initial stage.
When making a hole for the sink, cut it out slightly short of the markings. It's better to sand down a small cutout later than not to know what to do with a large one.
Experienced installers advise:
- Do not make the sink hole too large. If the structure “walks” in the groove prepared for it, you can’t even dream about the strength of the fastenings.
- Before using silicone, first check how long the substance will harden by applying it to an open surface.
- When installing a stainless steel sink, do not overtighten the mounting screws. This approach may damage the product.
- If rubber seals are not included in the kit, do not rush to the store. They can be replaced with silicone sealant.
- When tightening hardware using a screwdriver, be as careful as possible. By slightly tightening you can bend the structure. If you are not sure that you can calculate your strength correctly, it is better to use a Phillips screwdriver.
Don't skimp on sealant when installing a drop-in sink. It is better to wipe off excess from the surface with a cloth than to use a leaking structure
The most critical moment when inserting a sink into a countertop is marking the surface, and the most difficult is preparing the hole. One wrong stroke with a pencil or one mistake with a jigsaw in hand can simply ruin your new countertop. Do not repeat the mistakes of inexperienced masters, but do everything wisely. Happy installation!

Installing a sink into a countertop requires a lot of time and labor. But if you correctly cut a hole in the furniture block and carry out installation, washing dishes will not seem such a burdensome task. Next we will talk about how to cut a countertop for a sink.
Making and using a template
The process of installing a sink into a countertop consists of several stages. To properly perform this labor-intensive job, you need to carefully cut a hole in the tabletop, and it is advisable to follow the instructions below.
- First you need to purchase a blank sheet of cardboard of the required size from which the template will be cut. This work step will be simplified if the manufacturer, which often happens, made the template himself and included it in the product packaging. All that remains is to cut out the template using scissors along the drawn contour. If there is no template, you need to take the sink, turn it upside down, attach it to the cardboard, then use a pencil to draw the necessary outline and cut out the template along the finished outline. If there is no packaging with a pattern, and there is no necessary sheet of cardboard, the inverted sanitary ware is drawn directly on the countertop.
- Next, you need to evaluate the future location of the furniture block. You need to know in advance where the mixer will be installed, how to route the pipes, and whether the countertop will be trimmed before final installation. It is also necessary to examine the structure of the furniture from the inside. This will allow you to determine which elements, if necessary, can still be trimmed, and which cannot be touched - the load-bearing fragments of the tabletop must remain intact and untouched.
- Once the template is ready, it's time to use it. To mark the tabletop, you need to attach a template to its surface, and it must be motionless. After this operation, a contour is drawn. The same work is carried out if a factory template is available. You can cut right away along the outlined line. If cardboard is used or the upside down sink was traced with a pencil on the countertop, there is additional work to be done. The fact is that the drawn line will follow the edges of the sink, and its bowl will be inserted into the future hole. Therefore, you need to draw one more contour - the internal one. When drawing it, you need to take into account the distances from the edge of the sink to the fastening elements of the plumbing fixture. The result is a new template that is tailored to the dimensions of the bowl. It is applied to the surface of the tabletop and a new contour is applied along which a hole can be cut.
- There is an option in which a cardboard template is attached to the surface of the tabletop and a hole is sawed along its edges. If you look at such work from the practical side - it is inconvenient - it is better to draw the outline with a pencil. When cutting along a drawn line, there is a real chance of chipping on the inside edges of the tabletop. To avoid defects, it is recommended to stick masking tape to the surface in the area of the intended contour, which can be easily removed in the future. In order to start sawing, you need to make a hole in the body of the tabletop with a drill from the inside of the drawn line. A jigsaw file is pulled into the drilled hole, after which it is fixed in the tool. You need to cut carefully and without haste, since when pressed, the blade may move away from the intended contour.
- The resulting cut is cleaned with sandpaper, blown and thoroughly lubricated with silicone. Thanks to this composition, the harmful effects of moisture on the cut surface will be minimized. If any fragments of the furniture block interfere with the installation of the sink bowl, they must be carefully trimmed. Measurements for trimming must be taken accurately - it is not recommended to do such work “by eye”. You need to know that when using a template from the manufacturer, cutting out internal elements is much easier and simpler, since such nuances are also provided for in its manufacture.
Installing a sink into a countertop
- To begin the final installation of the sink, you need to do some mandatory work. First you need to try on the pipes and assemble the siphon, then you need to make holes in the internal structure of the tabletop for sewerage and water supply. All this work is performed with a jigsaw or crown. After this, the mixer is installed if a place has been prepared for it on the countertop. In addition, if necessary, the hoses are trimmed. If the mixer will be installed on the sink itself, a place for the equipment is determined on the plumbing fixture and a hole of the required diameter is drilled.
- Before installing the sink, a sealing tape is put on the sanitary ware - it usually comes with the device. The tape is fixed close to the edge, while a special groove is left free into which the silicone will be poured. Then the fasteners are installed in their places, which do not tighten when tightened - they will be firmly fixed after the entire structure is finally combined. If the faucet must be fixed to the sink, it is time to install it. The hole is generously smeared with silicone, after which the sanitary ware is installed in the hole under the sink. The fasteners must be bent before installation. In order for the sink to sit in its place and fit well into the contour of the opening, you need to move the plumbing fixture a little. After this, you need to crawl under the sink and finally tighten the fasteners. While the sealant is in a liquid state, it is wiped off - after some time the composition will set and harden. If there are gaps anywhere, they also need to be sealed with sealant.
The sink is installed in the countertop. The plumbing fixture can be used.
