How to fix a round sink. Installing and connecting a mortise sink with your own hands. Installation Basics for an Overmount Sink

In case of replacing the sink or purchasing a new one kitchen set it becomes necessary to embed a sink into the countertop. Execute this work You can do it yourself or use the services of a professional. The process is not complicated, but it requires attention and high-quality execution.

An incorrect installation of a sink into a countertop will result in water leaking into the piece of furniture, causing it to swell and, as a result, become deformed.

The purpose of a modern kitchen sink

In order to maximize the optimization of the food preparation process, you should correctly place furnishings and various equipment in the kitchen. According to existing principles of ergonomics, the placement of furniture and equipment in this room is carried out taking into account the order of work.

For this reason, furnishings are placed in the direction from left to right, and in a specific sequence: refrigerator - then dishwasher (if available) - kitchen sink - gas or electric stove. Modules with working surfaces should be placed between them.

It is also necessary to observe the minimum gaps between the above objects:

• the distance from the sink to the stove, as well as between it and the refrigerator, should be about 40 centimeters;
• The refrigerator and stove are installed so that there is 40 centimeters between them.

Before you embed a sink into a kitchen countertop, you need to choose it correctly, taking into account the following characteristics:

1. Functionality. It depends on the intended type kitchen work, the number of bowls in the sink and wings intended for drying. These objects will be used when the user is used to performing several manipulations at the same time.
2. Capacity. When determining this parameter, you need to take into account the number of dishes that have to be washed daily.
3. Durability and sustainability. They mainly depend on the material used to make the structure.
4. Design. The design of the sink must ideally match the surrounding interior so that it is a full-fledged object of the created concept.
5. Convenient use. Its configuration should ensure comfortable performance of kitchen work.

Types of sinks and their design features

There are a number of requirements for how to properly install a sink in a countertop. This process must be carried out according to technology. The choice of a specific solution regarding the installation method depends on the design of the sink.

The most popular types are:

1. Overlay products. Are considered the most budget option, which is easy to install the sink into the countertop. This installation principle is based on the fact that the sink is placed on a free-standing cabinet, as a result of which it is a continuation of the countertop. Sinks of this type have disadvantages - insufficient thickness of the material of the products and the presence of a gap between them and the tabletop, which causes inconvenience. Experts recommend choosing an overhead sink when there are several in your kitchen set. separate sections. If they are united by a common tabletop, the best option will be the use of an embedded model.
2. Built-in sinks. These products are installed directly into the countertop. Start off installation work follows by preparing holes in it. The technology of inserting a sink into a countertop involves attaching the structure to the inside of the module using special brackets and clamps. Built-in models of this type are distinguished by their solid appearance and convenient operation. Despite the fact that they are more expensive, specialists with extensive experience prefer them because of their practicality and the ability to prevent moisture from accumulating between the bedside tables.
3. Undermount sinks. The price of these innovative models so high that it makes them inaccessible to most consumers. The installation principle of such sanitary ware involves fixing them below the level of the countertop and therefore they form a single whole with it. Undermount sinks have an aesthetic appearance and good sound absorption. Thanks to effective sealing joints, these products are characterized by hygiene and long service life.

Materials for overlay and mortise models

These products are produced from of stainless steel. Today, both of them are the most popular. Externally, mortise options may look different. Stainless steel products with a smooth texture and a linen-imitating texture are often found.

In addition to traditional sinks made of stainless steel or enameled steel, inset options made of stone and composite materials. Bowls made from artificial stone. Sinks made from composite materials have an impressive grain structure and look like polished stone.

Mortise structures made from artificial raw materials are considered accessories for kitchens. They have excellent aesthetic and performance properties, including resistance to scratches, abrasion and sudden temperature changes.

The shape of sinks is varied: in addition to products with one, there are also those that have 2 - 4 bowls, which are shallow, deep and equipped with additional drainers.

The nuances of installing overhead sinks

The method of installing an overhead sink in a countertop has a number of features. Installation is carried out on a separate module so that it covers its entire upper part.

This work is simple, since L-shaped elements with an oblique slot are used for fixation. You should first prepare at least 4 - 5 fasteners. Before installing a sink in the countertop, you need to connect the mixer, which allows you to avoid any difficulties during installation in the future.

Overhead sinks are fixed in the following sequence:

1. The fasteners are applied to the inside of the kitchen cabinet and the appropriate marks are applied.
2. Screws of 15 millimeters are screwed in the designated places so that they are at least 5 millimeters above the markings.
3. The end of the cabinet is treated with a sealant to simultaneously protect the furniture and increase the reliability of the sink’s attachment.
4. The structure is placed on screwed screws and moved until it fits as completely as possible.
5. Next, fix the fasteners and remove excess sealant, after which the sink is connected to the water supply and drainage system.

Installation of a built-in sink into a countertop

Next, we will describe how to install a mortise sink into a countertop made of chipboard and coated on the outside with plastic. If you need to find out how to do this work when the countertop is made from other materials, you can read the product passport, in which the sink manufacturer gives appropriate recommendations.

The process of how to embed a sink into a countertop has several stages:

1. Preparing a set of tools and purchasing building materials.
2. Marking.
3. Creating a hole in the countertop.
4. Cut processing.
5. Tabletop mount undermount sink.

Preparation of tools and materials

Before you embed a sink into a countertop with your own hands, check that it is complete with fasteners. Usually they are clips. They are placed on both sides, placed on the cut end and on the inner surface of the sink. The kit should include a tubular seal used to seal the joints.

• electric jigsaw or hand tool and a set of saws for woodworking;
• drill with a 10 mm metal drill bit;
• self-tapping screws;
• measuring instruments - level, pencil, ruler, tape measure;
• Phillips screwdriver and knife;
• silicone colorless sealant.

Marking

The following describes the procedure for installing a rectangular mortise product. To figure out how to cut a tabletop for a round sink, you will need to additionally familiarize yourself with the nuances of this work.

Perform the markup like this:

1. With a pencil, in the place where the sink is planned, draw two perpendicular lines - the drain will be located at the point of their intersection.
2. The sink is turned over and placed on the countertop with the bowl up and aligned according to the markings, with the intersection visible through the drain hole.
3. With a simple pencil, trace the outer edges of the product along the perimeter. It is important not to forget to take into account the parameters of the sink and the relative location of its boundaries and the remaining free space countertops. To ensure that the mortise bowl does not interfere with the closing of the doors, it should be located inside the bedside table.
4. Then they measure the width of the side of the product and, in accordance with it, draw an internal contour; a cutting line will run along it. On average, this value is about 12 millimeters.

Before installing a sink of a round or other shape into the countertop, you need to act so that it fits freely into the hole, while deviation from the markings is allowed not exceeding 3 millimeters.

Creating a hole in the countertop

Work related to how to properly cut a countertop for a sink is done with an electric jigsaw, adhering to certain rules:

1. Before I drank of this instrument will penetrate the material to its full depth, it is necessary to create technological holes in the corners of the internal marking using a drill or screwdriver. They will simplify further work. In this case, the corner holes are placed in the inner plane of the material being cut, and their edges can only come into contact with the cutting line.
2. In order to prevent the appearance of chips on the laminated coating, all work regarding how to properly cut a sink in a countertop should be done on it front surface.
3. After holes are created in the corners of the plane to be cut, a place for washing is cut out with a jigsaw along the inner border of the cut. To prevent the cut part of the tabletop from falling, self-tapping screws are screwed along the line of movement of the jigsaw to ensure its fixation.
4. After the hole is prepared, the fasteners are removed and the cut is cleaned of dust. The sink is first placed in place to ensure it fits the size of the product. The sink should be installed freely in the finished hole. If you have difficulties with how to insert the sink into the countertop, you should trim the edges using a jigsaw.

Slice processing procedure

Experienced experts advise: since in the process of creating a hole along the inner edge of the cut, roughness and small chips often form, you need to become familiar with the rules for processing the cut, failure to comply with which leads to a number of problems:

1. So how to ensure absolute sealing of an unprotected chipboard surfaces impossible, its insufficient degree causes moisture to penetrate into this part of the countertop. As a result, the processes of decay may be activated and a fungal coating may appear.
2. Subsequently, the cutting edge becomes brittle and the stability of the shell decreases, which ends in its distortion.
3. As a result of rotting of the countertop, its aesthetic, strength and performance qualities are reduced and then replacement will be required.

To prevent the above-described troubles, you should:

1. Treat the end surface of the cut with fine-grained sandpaper and treat it with high-quality plumbing sealant. Professionals recommend using a spatula to perform this work; in the absence of which, the composition can be applied with your finger. Carrying out protective measures helps prevent wetting and subsequent swelling of the surface of the cabinet.
2. If, when performing work such as cutting out a sink in a countertop, chips are found on the front side of the plastic, they are carefully treated with sealant, and there is no need to apply it in a thick layer, since in this case the thickness is not important.
3. There is another way to protect the end side of the cut - it involves treating it with PVA glue. Despite the labor intensity this process, it is reliable, just like previous version. To enhance the protection effect, the applied layer of glue should dry for approximately 30 - 50 minutes.
4. Next, you should glue the seal made of foamed polyethylene; it is usually included with the sink. This material is fixed on the side of the sink along its perimeter. When, after attaching the seal, it can be seen, the material is carefully trimmed with a knife. If this is not done, the edges of the sink will not fit tightly to the countertop and water, getting into the gaps created, will cause swelling and further rotting of the end.

Since the process of attaching the seal directly affects the performance and wear resistance of the kitchen set, attention should be paid to it:

1. You need to take the material and degrease it with a rag soaked in gasoline and solvent.
2. Then sealant is applied to the seal in a continuous thin strip so that the glue does not come out when compressed and pressed against the outer edge of the sink.

Attaching a mortise sink to a countertop

You need to know not only how to fit the sink into the countertop correctly, but also how to securely fasten it:

1. A layer of silicone is applied to the space between the outer marking line and the cut.
2. On inner side Mount the fasteners on the sides of the bowl and, making sure that they are not completely fixed, proceed to install the product.
3. The process begins by deepening the side where the location of the crane is planned. The rest of the structure is gradually lowered into the hole until the sides and inner surface countertops.
4. During the installation process, you need to work on the entire surface of the sink, which will allow you to remove excess silicone from under its sides.
5. Applying building level, you need to make sure that the installation was carried out correctly and then proceed to the final stage, during which the final fastening of the fixing parts is carried out.

After completing the above steps, you can begin connecting engineering communications. Hoses hot and cold water connected to the water supply using sealing gaskets.

• a siphon outlet is inserted into the sink; experts recommend using it S-about different shapes;
• a pipe is connected to the siphon - either a soft corrugated one or a hard angular one;
• the tube from the siphon is discharged into the sewer;
• All connections are checked for leaks.

Creating a hole in an artificial stone countertop

Most often, when purchasing a countertop made of artificial stone, you do not need to think about how to embed a sink, since it is ordered with an already prepared hole designed for specific dimensions.

If these conditions were not specified when placing an order, such work can be done by craftsmen using special tools. They will use them to make a hole of the required size and shape.

Features of installation of round sinks

The method of installing a round sink into a countertop has much in common with installing a rectangular product, but there are some nuances:

1. Along the cutting line it is necessary to create several holes at intervals of 7 to 10 centimeters, which greatly simplifies the work.
2. If, when purchasing a sink model, it was not equipped with a template for the cutout, you can create one yourself.

Nuances of installing corner and granite sinks

The technology for installing granite sinks has specific features:

1. The design of such a sink does not provide for the presence of holes for a faucet and the placement of a drain siphon.
2. They are made independently, using a drill with a special attachment.

Kit kitchen furniture includes many components for various purposes. The central element of the headset is this room you can call it a tabletop. It's not just basic working surface, but also a kind of frame with which kitchen communications, shelves, cabinets and, of course, the sink interact. And if the communication connection is carried out according standard schemes with given hole parameters, then integration functional elements entering the platform niche itself requires more serious preparation. Cutting and fastening operations are only part of the work steps that a tabletop cannot do without. Implementing these and other tasks on your own is not easy, but it is possible if you follow the instructions.

Preparation for installation activities

Before starting work activities, you should prepare Consumables, tools and directly washing. By this point, the countertop should be installed, and the material of its manufacture should match the sink. The fact is that different table tops depending on the standard size and material of manufacture they have different bearing capacity. Thin models based on composites can only withstand stainless sinks. If you plan to install a stone sink into the countertop, then you should focus on a high load. IN in this case either the tabletop must be made of at least artificial stone, or additional holders are provided in the cabinet itself under the platform.

As for the tools, you should prepare a set measuring instruments, electric drill or jigsaw, screwdrivers, adjustable wrench, construction knife and a sealant gun. What consumables will be needed depends on the installation method, which will be discussed below. The universal list includes screws and sealant. In addition, do not forget about the plumbing, the organization of which involves the use of a siphon, a water supply hose and a mixer.

Rules for marking

This is a critical stage, during which the configuration of the sink placement will be determined in accordance with its size. Of course, you should start from the parameters of a specific sink, but there are also standard placement rules that the chosen installation scheme should not contradict. First of all, the cutting edge, that is, the line of contact between the sink and the countertop, should be located at least 50 mm from the edge. This value should be maintained regardless of the method used to further install the sink into the countertop.

You can install the sink yourself using both glue and hardware, but in both cases the load on the edge must be minimized. The only exception is the area with the rear end, where the distance from the edge to the cut can be 25 mm, since in this part the pressure on the structure will be less. Also, when marking, you should remember about the communications that will be connected to the central point of the sink - they must fit freely to ensure both water supply and drainage to the sewer.

Cutting countertops to size of sink

After marking, the lines for future cutting should be ready. To perform cutting, two tools are used - a jigsaw and an electric drill. First, a drill comes into play, which will create niches for sawing. If installation is planned, it is necessary to make holes with a depth of at least 10 mm in each corner. Next, from each hole you need to use a jigsaw to connect to another nearby point along a straight cutting line.

A different approach should be used if a round sink is installed in a countertop. It is more difficult to cope with this task on your own, since you will need to perform not a straight, but a curved cut. But you should also start by creating a hole with an electric drill. It will be one. To make cutting easier, it is advisable to initially have a jigsaw designed for figure cutting. Then you should carefully guide the saw strictly along the intended circular line. It is important to avoid even small deviations and to cut smoothly and without jerking.

Installing a sink using glue

The adhesive method of fixing the sink is not the most reliable, but it is practical and, provided it fits tightly, can be quite durable. Before applying the glue, it is necessary to treat the edges of the tabletop at the cut points. For this, fine abrasive materials or a fine-grained grinding wheel are used. Next, a polyethylene-based sealant is applied. It is usually supplied complete with the product.

It is also worth noting that glue method Installation of a stainless steel sink into the countertop is carried out, but not stone models, the displacement of which can lead to a violation of the fixation. Both the future contact points of the sink itself and the polished edges of the countertop are first coated with glue. It will be possible to use the sink for its intended purpose only after the composition has completely crystallized - you need to wait about 24 hours.

Installation of sink with fastening materials

Mechanical fixation will provide greater reliability, but there is one caveat. The adhesive composition increases the tightness of the areas where the sink and countertop meet. In the case of screws, the risk of flooding at the joints will be prevented by using waterproof sealants in a larger volume than in the case of glue installation. Usually fastening material Comes complete, so you don’t have to look for special hardware.

A “cross” installation of the sink into the countertop is considered optimal. You can do this installation yourself either using a screwdriver or using a screwdriver manually. The fastening strips are positioned diagonally, after which the complete screws are integrated into the technical holes.

Inset and overhead sinks - differences in installation

Built-in sinks require customized installation, including with a shaped cut countertop. Overhead models are also rarely done without pre-treatment platforms, but in this case, markings for future cutting are made along straight lines. As a rule, a square or rectangular shape, and cutouts of this format are made in special panels at the factory.

What are the benefits of installing mortise sink on the countertop? Implement it yourself figure cutting for such a wash it is more difficult, but in the end it will provide more high degree reliability, not to mention aesthetic appeal.

Nuances of installing ceramic sinks

Both ceramic and stone sinks are made using the cut-in technique only. Such models require the creation of a more durable supporting structure with high-quality fixation. It is recommended to carry out fastening using a combined method - that is, using glue and mechanical clamps. This will ensure optimal installation of the ceramic sink into the countertop.

You can also prepare the internal holding base yourself. This is done using wooden planks, which insure the niche of the heavy tabletop under the cabinet. Such planks can also be fastened with nails, but a more preferable option involves the use of self-tapping screws or self-tapping screws.

Connecting the sink to communications

First, connect the cold and hot water. On one side - to the mixer, on the other - to the water supply channel. The integration point of the mixer must contain rubber compressor. Next, a siphon outlet is introduced into the sink - it is advisable to use a curved model, since bottle ones quickly become clogged. A sewer pipe is connected to the siphon.

If it was installed in a countertop, then the communication line should be used as strictly as possible. For example, the pipe may have reinforced corner structure. On final stage it is necessary to check all connections and, if necessary, provide sealing collars at the joints.

During the installation process, regardless of the installation method, a sealant will be used. You should not feel sorry for him, since the joints must be well sealed. However, excess that extends beyond the gaps must be removed before it dries.

Another nuance concerns working with stone and ceramic structures. This is the most labor-intensive installation of a sink into a countertop. It is physically difficult to carry out such installation on your own in the kitchen, so it is better to work with a partner. And one more point concerns the choice of the method of tightening the screws. If possible, it is better to perform such operations without power tools and manually, since excessive force can lead to deformation of the materials of the countertop and the sink itself.

Conclusion

How ergonomic a sink integrated into the countertop will be depends on many factors. Highest value the location of the object will be in general configuration headset Durability and reliability arranged structure In this case, it will be determined by the installation of the sink in the countertop. Self-installation can guarantee the success of future operation only if the above recommendations are followed, as well as high quality used consumables.

Particular attention in this context should be paid to the sealant and adhesive composition. It is advisable to choose both products from the lines of major manufacturers recommended for use in the kitchen under harsh operating conditions.

Today there is a wide variety of all kinds of mortise (built into the countertop) kitchen sinks made of different materials having various shapes and colors. The most popular, inexpensive and at the same time durable type kitchen sink can be considered stainless steel sinks. Let's look at how to install a stainless steel kitchen sink with your own hands, using simple household power tools. Absolutely any mortise sinks are installed using the same principle.

We will install the sink in a countertop made of chipboard, covered with plastic on top - the most common type kitchen countertop. If necessary, e When installing a sink into a countertop made of another material (for example, artificial stone), you must follow the recommendations of the countertop manufacturer. There are also overhead sinks that are simply put on (placed) on top of the cabinet; such sinks are considered obsolete and are used extremely rarely; they will not be discussed in this article.

To install a kitchen sink, we need:

1. Pencil, tape measure, ruler, construction angle, Phillips screwdriver, sharp knife.
2. Jigsaw with file type Bosch T101B orT101BR.
3. Electric drill with a metal drill with a diameter of 10-12 mm.
4. Several self-tapping screws 16-30 mm long.
5. Silicone colorless sealant (universal or plumbing).

FilesBosch T101B (top) andBosch T101BR (bottom).
They differ in the direction of the teeth: straight andthe opposite(reverse) respectively.

Marking.

Accurate marking is the key to successful installation. To begin with, you need to decide on the axis of symmetry, that is, symmetrically to what the sink will be installed. Usually, the line of the center of the sink bowl (for a round one - its diameter) goes along the center of the cabinet above which the sink is installed. Other installation options are possible, depending on specific case(kitchen set configurations). Indent from leading edge table tops, as a rule, should not be less than 50 mm, from the back - less than 25 mm. However, these figures cannot be considered universal, and depending on the size of the sink, as well as the features of the insert, the figures may be different. With a pencil we draw two perpendicular axes on the front surface of the tabletop, indicating the center of the bowl and mark the boundaries of the sink (left, right, top, bottom).

Indentations from the edges of the tabletop.

Place the sink on the front surface of the countertop with the bowl facing up and align the sink relative to the markings made. Carefully, without moving the sink from its place, outline the outer contour of the sink with a pencil. We remove the sink from the countertop.

Depending on the manufacturer, the stainless sink kit (d Most sinks made of artificial stone do not have such fastenings.) may include metal, or plastic fastenings. If possible, preference should be given to metal (all-metal) fasteners, as they are more reliable. Before installing the fasteners on the sink, it is recommended to disassemble them (by separating the parts mounted on the sink and on the countertop from each other). By snapping, the parts of the fastenings are installed on the sink into the corresponding metal eyes so that the fastenings minimally protrude outward - “looking” into the inside of the sink.

Part of the fastening installed on the sink.

We accurately measure the width of the sink side (the distance from the outer edge of the sink to installed fasteners), taking into account the protrusions of the fasteners. As a rule, the width of the rim of a stainless steel sink ranges from 10 to 15 mm.

The sink is ready to be outlined on the countertop.

Parallel to the outer contour of the sink previously drawn on the countertop, draw by hand (or using a ruler to control accuracy) another contour - the cutting line - inside (closer to the center of the sink), indented by the width of the side of the sink minus 1-2 mm. The sink should fit freely into the future hole, allowing up to 2 mm of play on each side.

Marking the cutting line.

Cutting a mounting hole in the countertop.

In one (for a round sink) or several places (in the corners of the markings, for a rectangular sink) of the countertop, we make a through hole with a 10-12 mm drill so that the future hole is close to the cutting line, but does not touch it (it is closer to the center of the sink) . It is necessary to drill from the front surface of the tabletop! We get a hole(s) for the file to enter.

Using a jigsaw, exactly along the cutting line, we make a closed cut. To inner part the table top remained in place (did not fall down), you need to screw screws into the gap from time to time, which will act as temporary fasteners (wedges). We insert the sink into the countertop, check that the cutout is made correctly (the sink should fit freely with a slight play), if necessary, perform additional trimming with a jigsaw.

Close-up of the hole.

Small chips of plastic are acceptable.
To avoid chipping at all, you need to use a fileT101BRwith reverse direction of teeth.

After sawing is completed and the unnecessary (inner) part of the tabletop is removed, it is necessary to clean the cut from dust and carefully cover it silicone sealant(using small rubber spatula), this will prevent the tabletop from swelling when water gets in. You also need to lubricate the plastic chips that formed during sawing. There is no need to get too carried away - there is no point in covering the cut with a thick layer of sealant.

Applying sealant to the cut.

We glue a sealant made of foamed polyethylene (included with the sink) to the side of the sink around the entire perimeter. If, after gluing the seal, it protrudes beyond the outer contour of the side (rises above it) by more than 1 mm, then the seal must be trimmed with the sharp tip of a knife, otherwise there is a possibility that the fasteners will not be able to fully press the seal and press the sink to the plane of the countertop . If we are dealing with a sink made of artificial stone, then there is no need to glue any seals.

Using a clean cloth soaked in gasoline or acetone, degrease the surface of the seal and the line of contact of the seal to the countertop. We apply the sealant to the seal in a continuous strip, not being carried away by the thickness of this strip (it is assumed that the seal is glued flush with the protrusion of the side). In practice, you can find a way to install a stainless steel sink without using a sealant at all; in this case, the entire space designed for inserting the sealant is filled with sealant. This is acceptable, but not advisable for several reasons: high consumption sealant (as a result, for a long time drying), difficult control of filling the seam, labor-intensive process of dismantling the sink in case of unsuccessful installation. An exception is the installation of a sink made of artificial stone; such a sink is mounted only on sealant.

Applying sealant to the seal.

Sink fastening.

We insert the sink into the hole in the countertop and align it with the markings (the markings must be applied so that they are partially preserved after cutting out the countertop). We take two or four fasteners and, equidistant from each other, pre-fasten the sink (without fully tightening the fastenings), constantly monitoring its position relative to the markings. Attention! Tightening the sink fasteners must be done manually, without using a screwdriver, since the threads are plastic parts breaks easily! We turn the tabletop upside down (for convenience), install all the fasteners, and finally tighten them, trying to do this evenly and consistently. So that the sharp spikes of the fastenings the best way stuck into the countertop, you can sharpen them with a file and/or lightly tap them with a hammer while tightening them.

Mounting on the sink in assembled form. By tightening the self-tapping screw, the sink is attracted to the countertop. The sharp ends of the metal part of the fastening must be securely fixed in the tabletop.

Tighten the fasteners with a screwdriver.

The fastening is tight. It is recommended to lightly tap the fastener with a hammer so that the sharp ends cut deeper into the tabletop.

All fastenings are tight.

Let's look at the result of the work: the sink should be pressed along the entire perimeter to the surface of the countertop, installed along the marking lines. Indirect confirmation of the complete fit of the sink can be the squeezed out sealant. Use a cloth to wipe off excess sealant and markings from the front surface of the countertop. Allow the sealant to harden overnight. If the sink is made of artificial stone and is not equipped with fasteners, it is necessary to ensure that it is completely immobile while the sealant is curing.

The sink is well pressed to the countertop. The sealant squeezed out slightly.

Installing a built-in kitchen sink is a responsible undertaking. Poor quality installation of a sink can not only ruin appearance kitchens, but also lead to rapid failure of the countertop due to the penetration of water under the sink onto the cut of the countertop. Primary importance should be given to sealing the sink-countertop joint; do not rely on well-executed processing of the cutout end.

If you are interested in how to embed a sink into a countertop, then you have come to the section you need and can learn more about it, with all the installation nuances. But we warn you right away that this method applies only to countertops made of chipboard - you cannot make a hole in artificial or natural stone using the same method.

But you can insert the sink into a regular countertop in the place you need, and in addition to our story, the video in this article will help you with this.

Built-in sinks

Installation Methods

First of all, let's define what a built-in sink or sink is, and if you need to cut the sink into the countertop with your own hands, then this is the type of container we are considering. But the installation itself when inserting may differ, that is, it can be either overhead or built-in.

Overhead models can have different shapes, but they always have a horizontal edge that rests on the countertop - it is thanks to this that the sink is fixed - it is superimposed. In addition to the horizontal sides, there may be a corrugated pedestal in the form of a small table - it is intended for storing dishes when washing.

But, to the tabletop with glue and/or various clamps - it all depends on the design of the model. With this installation option, the sides of the sink never rise above the countertop - they can be either at the same level (flush) or slightly lower, as shown in the top photo. Such sinks are made of stainless steel, natural or artificial stone (granite, marble) and even ceramics (faience, porcelain).

We cut in the sink

• Now we will figure out how to properly embed a sink into a countertop and to do this we will show you in photographs one of the complex insertion options, when the sides are below the level of the countertop.
• When the place of the cut is blocked by the sides and is not visible, but in this case, this cut will be obvious, therefore, it must be made with perfect accuracy. To do this, we will need a template, which can come with the sink, or you will need to make it yourself.
• Choose Right place on the tabletop where the insertion will take place (it is best to do this with a tape measure) and secure this template there with clamps so that it does not get lost during operation. Please note that the instructions require maintaining a distance from the edge of the tabletop - it must be at least 50 mm (this is for a safety margin).

• In order for the cut to be beautiful and even, we will not use an electric jigsaw, but a milling cutter with an end cap. The insertion (selecting grooves) will be done in three passes and now we will need to go through the first level.

• Now we need to remove the sharp upper edge of the cut, and we will do this with the same cutter, but with a 2-3 mm radius nozzle. Of course, you can remove such an edge manually - with the same rasp - but working with a milling tool is the most accurate, and that’s exactly what we need.

• Now we select a groove from the bottom side - this is where the sink will be placed; as a rule, such work is done with a milling cutter in three passes. After this you will need to manually, sandpaper, sand the cut to the desired level of shine - the more shiny it is, the better it will look. Now the entire cut surface needs to be wiped with some solvent or isopropyl alcohol, to delete adhesive connections Chipboard.

• For installation we will use polymer adhesive based on modified silane - its price is quite affordable, but the effect is excellent. Turn the countertop over with the wrong side up, apply glue to the selected grooves and carefully lower the sink there.
• Now, for a clear fixation, you need to press the sink with clamps for 12 hours, just be sure to place some kind of spacers in the places of pressure (you can use pieces of a cut-out countertop).

• After 12 hours, remove the clamps and stabilize the fixation on the underside of the sink along its perimeter- Two-component adhesives such as epoxy resin are well suited for this.
• This connection hardens quite quickly., and stick foil tape around the perimeter on top of the frozen mass, which is needed for waterproofing. Now turn the tabletop over initial position- when knocking around the perimeter of the sink, you will see glue residues - carefully remove them with a knife.

Recommendation. Until the countertop and the sink glued to it are installed on the cabinet frame, you need to attach the siphon and faucet.
At this stage, such work is much easier to do than after final assembly furniture.

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 have already said, installing a kitchen sink involves two options:

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:

1. You must first supply water to the installation site.

1. 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.

1. 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 exude bad smell, simultaneously destroying the countertop under the countertop sink. We simply recommend not using it at work.
2. When purchasing a kitchen sink, find out if it comes with a template or stencil that will help you cut it into the countertop. 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

1. 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:

1. 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.
