Installation of a wall hung toilet. How to install a wall-hung toilet - step-by-step instructions. What to consider in advance
Wall hung toilets with installation are the most modern, compact, and attractive in appearance plumbing devices. Installation wall hung toilet takes more time and effort, but we still prepared this article with step-by-step instructions with our expert master.
The cost of such toilets is much higher than standard plumbing, but all costs are justified by comfortable operation.
Despite all the difficulties, home craftsmen, after studying detailed instructions, successfully carry out the installation with their own hands.
Design Features
The design of the wall-hung toilet is distinguished by many elements hidden in the walls. The frame is based on a durable metal frame installed inside a wall niche.
For reliable fastening, it is fixed to the floor and wall.
Another element is the tank; as a rule, it is made of plastic and has flat shape. The tank is usually already fixed to a metal frame. The main element of the toilet is the bowl. Its installation is carried out outside the wall, that is, after all processes are completed, the user will only see the bowl and flush buttons (located on the wall). All other parts will be covered with a plasterboard partition and tiles.What to consider in advance
When installing a wall-hung toilet with installation, much more attention is paid to the preparatory work:
- choice of location;
- plumbing and system installation sewer drain;
- carrying out accurate measurements and calculations to determine the installation height of the toilet;
- preparation and procurement the required set tools and installation kit.
Installing a metal frame
The metal frame is the basis of the installation, on which all structural elements are fixed - the tank and the bowl. Considering the type of toilet in question, it is important to note that the frame will be located in the wall, in a pre-formed niche. This must be foreseen in advance, even at the renovation planning stage.
You can purchase a metal frame either complete with a toilet or separately. When buying a frame, the main attention should be paid to the quality of the metal, and dimensions, in particular depth. In standard models, it is in the range of 23-25 cm.
Frame assembly and installation steps:
First of all, we attach a hidden plastic tank to the frame frame using bolts ( if the tank was supplied separately from the frame).We place the frame into the niche and attach it to the floor and walls with brackets. It is important to immediately set the levels correctly (vertical and horizontal).
After installation, the height of the frame is adjusted according to previously made measurements and a schematic illustration. Typically, the installation is height-adjustable using special “legs”-brackets on its lower part. By unscrewing or tightening them, we adjust the height of the installation communications to the required level.
A guide cuff is placed in the sewer drain, which is usually included with the frame. The drain pipe is fixed to the frame.
When performing all manipulations, it is also necessary to monitor the evenness of the entire structure horizontally, vertically and on the walls. To obtain an accurate result, the master uses a building level.
Wall cladding
After assembly metal frame and its reliable fixation, special long bolts are attached to the frame. These are special, especially strong bolts that will connect the installation in the wall with the toilet bowl from the outside.
Following the diagrams and instructions included with each model, the remaining parts are assembled, the installation of which is hidden. So, you need to secure the buttons and a special cover for them so as not to damage them while covering the walls.
Let's complete the process of assembling the main structure and move on to covering the walls. In other words, you need to hide the built-in niche. What finishing materials to choose for this depends directly on the owner of the house. As a rule, the walls are sheathed with plasterboard and then finished with tiles.
For sheathing, you need to install metal guides, which are sheathed with moisture-resistant plasterboard.
In this article we will not describe in detail the process of covering a wall with plasterboard; for this we have a separate detailed article. Technical holes are cut in the drywall:- for fastening bolts;
- for water supply pipes to the tank, sewer;
- for a panel with flush buttons.
Installation of a wall-hung toilet bowl
The final stage of installation wall hung toilet The installation involves installing the bowl in the intended location and mounting the flush panel. You can continue working only after waiting completely dry tile adhesive.
The wall-hung toilet bowl is hung and secured with special long bolts. The outlet is connected to the sewer pipe.
A panel with buttons that regulate flushing is installed on the control panel.
After completing all the work, you must check the functionality and tightness. Open the tap to supply water to the tank. After waiting until the tank is completely filled, flush. If there are no problems or leaks, then all manipulations were performed correctly.
Proper installation of a toilet installation begins with checking the location and walls, especially if the toilet is supposed to be mounted on a wall. It must support the weight of a person. For this, powerful fasteners are used that are mounted on the main wall.
If the walls are in order, then you can proceed to the next stage - marking the walls for attaching the frame. The rigidity of the final structure, its reliability and correct location all the details. Our plumbers use laser levels and professional rulers that provide accuracy down to tenths of a millimeter.
Mounting the installation
The next stage is attaching brackets or anchors. They are usually supplied with the installation. Sometimes it is better to buy stronger anchors if you think that those offered by the supplier are too flimsy.
In addition, installation installation at this stage must be carried out in a certain order, which is duplicated in special instructions to the equipment. Different installation systems are mounted in different ways, so it is important to take into account the features of a particular system.
After attaching everyone necessary elements, installation of the installation frame or its blocks begins, depending on the type. At this stage, you need to perfectly align the frame in the vertical and horizontal dimensions. This is done by adjusting the bolts and legs of the structure in height.
Depending on the type of construction (floor-mounted or wall-mounted), installing a flush-mounted toilet may require additional fastenings or height adjustments. It is important to ensure correct position all design details.
Connection to communications
It is not enough to simply install the equipment; it is important to ensure its functionality. After the installation of the wall-hung toilet with installation is completed, you need to connect and insulate the inlet hoses and drain pipe. After connecting, we turn on the water and check the joints, the rate of water intake, and the pressure when draining.
Installation problems
If installed incorrectly, the following problems often occur:
- leakage cistern due to incorrect position of gaskets;
- stagnation of water in the drain due to improper position of the drain pipe;
- leaking toilet due to weak gaskets;
- wobbling toilet and cistern.
Our plumbers can easily solve these normal situations by tightening the bolts, replacing the gaskets or changing their location. After final testing of the design, it works without problems.
Features of working with installations
This is complex equipment that requires proper installation. When installing a wall-hung toilet with installation, it is necessary to constantly monitor the position individual elements designs. During operation, the frame often shifts and changes the angle of inclination, so you need to level it and adjust the bolts.
It is important to correctly attach the drain button at a height of no more than one meter, the sewer pipe should be located at a height of 22-23 cm, the drain should be strictly at an angle of 45 degrees. Otherwise, the flushing process will be difficult, the water will begin to stagnate, which can lead to unpleasant odors and damage to the structure.
Installation nuances
Installing an installation for a wall-hung toilet is more difficult. In this case, you need to take into account several details:
Wall strength;
Position of the drain pipe;
The height of the toilet. Mounting too high will make use uncomfortable;
Possibility of water supply.
All these issues are technically solvable, but this may require additional costs.
Bidet installation
In principle, installing a bidet with installation is carried out in approximately the same way: marking, fastening, mounting the structure, connecting communications and checking functionality.
Exist technical features, Related different designs bidet, water entry and drain points, type of mounting (wall or floor). Our plumbers are familiar with these details and will get the job done quickly.
How much does the installation cost?
In Moscow, the cost of installing an installation starts from 4-5 thousand rubles and can consist of the following parameters:
- the cost of installing the installation itself;
- cost of installing a toilet or bidet;
- the cost of installing keys and flush buttons.
This price only includes plumbing work(without wall finishing, tiling, etc.). All work performed is covered by a guarantee.
What does the price depend on?
It is important to consider that the cost of installing an installation for a wall-hung toilet depends on the complexity of the design, manufacturer, size of the room, the presence of additional functions, and so on.
Sometimes during the installation process we see that it is worth changing the supply pipes or fasteners, or replacing fittings. We will tell you about this right away, because then, after finishing, it will be very difficult to get to the communications, and to change worn elements have to.
Design features
If you want to place the toilet in the middle of the bathroom (and this is possible), then we will need more time for installation, organizing communications and checking the functionality of the structure. Therefore it will cost more
TO difficult decisions This also includes work in cramped conditions, work with heavy structures, when the participation of several plumbers is required.
Call our specialists and tell us about the task. After a few questions, we will be able to tell you how much it costs to install a toilet in your case, how long it will take and arrange an appointment.
Our specialists arrive on the day of your order or the next day. We are familiar with different systems, so we will arrive with all the necessary equipment.
Due to a number of advantages, wall-hung toilets are steadily gaining popularity.
In reality, everything is not so scary at all, and even a beginner will be able to install a wall-hung toilet with an installation, if only he carefully reads the instructions.
When purchasing, you should first pay attention to its material and shape.
A variety of materials are used, but the vast majority of devices are traditionally made from two types of ceramics:
- Faience: the material is inexpensive, but due to porous structure Indelible yellow stains soon appear on it.
- Porcelain: There are no pores in this material, therefore appearance the product remains attractive longer. But it also costs a little more.
Other materials have the following advantages:
- stainless steel: not afraid of impacts, therefore suitable for public places;
- acrylic and other types of plastic: budget option;
- natural stone: luxury toilets, so to speak, executive class.
The most preferred are round or oval shaped bowls. Rectangular ones are also made, but as practice has shown, they are less convenient to use.
Don’t forget to make sure that the chosen model fits well in the room: for comfortable use, there should be at least 60 cm of free space in front of the toilet.
Installation selection
Includes several components:
- support frame;
- cistern;
- pipes and fittings for connecting communications.
First of all, these designs differ, which can be:
- Frame: such installations are called free-standing. They transfer the entire load only to the floor, so they can be installed even near a cardboard screen. Recognize frame installation possible with reinforced legs. In contrast to block ones, they are more expensive and take up more space.
- Block: such installations are also called wall installations. They are designed for hanging on a permanent wall. Trying to attach a block frame to a flimsy partition will end in disaster as soon as the wall-hung toilet comes under load.
Toilet after installation
If there is a solid wall in the bathroom, such structures should be given preference because they:
- are the cheapest;
- They have a small depth, as a result of which the room loses little in volume.
When choosing an installation, we must not forget that this plumbing fixture is installed in a hidden way, so it is extremely important that it is of sufficient quality. Leaks will be very expensive, not only because of the need to dismantle the partition, but also because the water will not be immediately detected and will have time to properly flood the neighbors.
To minimize the risk of an accident, conscientious manufacturers develop reliable designs and use only the highest quality materials. Cheap imitations are assembled from whatever is available, so the money saved will most likely have to be paid for restoring the neighbor’s interior.
Vitra Zentrum kit
The design of the installation, for obvious reasons, does not matter, which cannot be said about the flush button. It is available in the most different versions, so you can find suitable option for any interior. In addition, the flush buttons differ in their mode of action:
- In mechanical systems, the connection between the button and the drain valve is carried out through levers and rods. A simple, uncomplicated option and at the same time the cheapest. The disadvantage of such a button is that it can only be installed in a strictly defined location.
- Pneumatic ones are connected to the valve by a tube in which pressure is created when the button is pressed. It opens the valve.
The latter option costs a little more, but installation is possible anywhere the tube can reach.
Required tools and materials
Here's what you need to arm yourself with to successfully cope with the installation of a wall-hung toilet:
- hammer drill or hammer drill with a set of drills for concrete;
- rack level (also called bubble level);
- grinder or pipe cutter - depending on the material of the pipes;
- gas key;
- screwdriver;
In the case of using plastic pipes, you may additionally need a special heater (for welding polypropylene pipes) or press pliers (for installing fittings on metal plastic pipes).
You will also need to prepare some materials:
- Anchor bolts. Usually 4 pieces are used.
- To make a false wall, you will need galvanized profiles, dowels and moisture-resistant plasterboard or the same gypsum fiber sheets.
- Sealing material for pipe threaded connections. When using today's popular flexible hoses, sealing material will not be needed, but it is better not to use them to connect the installation due to insufficient reliability. It is more correct to connect pipes to the pipes using couplings, and here you cannot do without a sealant.
Experienced craftsmen prefer tow or plumbing flax with Unipak paste, but a beginner should not mess with such a sealant: if it is “overdosed”, the screwed-on part - a coupling or a tap - may burst. Less demanding in terms of experience and skills are fluoroplastic sealant (FUM tape) and “Tanget Unilock” linen thread.
You must make sure that the purchased toilet is fully equipped. In the package the user should find:
- cup;
- installation with a tank, fittings and pipes;
- flush button (usually selected separately);
- soundproofing plate.
The kit must include vapor barrier material, with which structures are protected from condensation.
Installation of a toilet with installation
In this order:
- The installation is installed in place and secured. It is important that it is installed without distortions, so the position of the frame must be controlled by a level. You can level it using adjustable legs.
- Communications are supplied and connected to the installation - sewerage and water supply. To connect sewer pipe you have to use a 45 degree bend.
- All connections must be carefully sealed. When connecting the sewer, you should not rely on the reliability of the rubber cuff - the rubber dries out over time. The joint should also be filled with sealant. The sewerage outlet on the installation must be closed with a plug so that unpleasant odors did not enter the premises.
- After connecting the installation, the studs are screwed into it to secure the toilet, and the flush tank is closed with a lid. To prevent the threads on the studs from being contaminated during installation and finishing of the partition, plastic sleeves are placed on them.
- A test is carried out: the toilet is hung and connected to the tank and sewer, but not secured, after which a test flush is performed. If leaks are detected, the connections are repacked. After checking, the toilet bowl is disconnected.
- A partition is being installed. For fastening frame profiles and plasterboard sheets You should use oxidized or phosphated self-tapping screws, which can be identified by their black color. Conventional fasteners in conditions high humidity will corrode.
Access to the main components of the installation can be obtained through the flush button, but, nevertheless, it is advisable to provide hatches in the partition for quick access to other components.
Installation installation
The finished partition must be covered with tiles or other material.
- A flush button is installed.
- A soundproofing plate is installed. It needs to be put on the studs and sewer outlet, for which they are freed from plastic sleeves and plugs.
- The bowl is hung on the pins. At the same time, it is connected to the sewer outlet and the tank pipe. Both connections must be sealed using sealant, which is applied to one of the contacting surfaces before installation.
- Nuts and washers are screwed onto the ends of the studs, and decorative caps are placed on top of them.
- The edges of the soundproofing plate protruding from under the bowl are trimmed, and the contact area with the wall is treated with sanitary sealant.
At this point, the installation of the wall-hung toilet is considered complete.
By understanding the technology for installing a toilet, you can save on plumbing services and get the job done to the highest possible quality. The toilet can be mounted traditional way or more modern method- with installation. In the second case, the cistern will be hidden in the wall, which will have a positive effect on the interior of the room.

In the case of installing a toilet on an installation, the listed list will be expanded with the corresponding set. Everything you need can be purchased at any plumbing store.
Removing the old toilet
First step . Turn off the water supply and drain all the liquid.
Second step. We unscrew the hose through which the tank is connected to the water supply.
Third step. Unscrew the tank fasteners. If they are rusty, we arm ourselves with a screwdriver or open-end wrench. Press the bolt head with the selected tool and unscrew the nut using adjustable wrench. If that doesn’t work, pre-soak the nut with kerosene. We remove the tank.
Fourth step. We dismantle the toilet mountings.
Fifth step. Disconnect the toilet flush from the sewer.
In older buildings, drains are usually secured using cement coating. To destroy it we use a hammer and chisel. We need to crack the cement and carefully rock the toilet to the sides. The drain should turn and become loose. We tilt the product, allowing the remaining water to drain into the sewer.
If the toilet had an outlet to the floor, it is necessary to clean off the wax ring Sixth step. We close the sewer hole with a wooden or other suitable plug.
Important! Sewage gases do not have the most pleasant smell. However, they are poisonous and flammable. Be sure to take this point into account as you work.
Getting ready for installation
The base for installing the toilet must be level. There are several options for the development of events, namely:
- if the floor is tiled and does not have differences in level, we do not carry out any preliminary measures to level the base;
- If the floor is tiled and is not level, we install the toilet using choppers. To do this, holes are drilled in the floor, the choppers are driven into them at a level, and then the toilet is attached to the choppers using screws;
- if it is planned to replace the tiles, dismantle the old cladding and fill in a new screed if the old one has differences in level;
- if the toilet is installed in a new house or apartment without any finishing, fill in the screed and lay the tiles.
We pay attention to the pipes. The sewer line is cleared of debris and various deposits; we install a tap on the water supply line (if it was missing before) to shut off the water supply to the tank.
Installation procedure for a regular toilet
As a rule, when selling, the toilet and cistern are disconnected. The internal fittings of the barrel are most often already assembled, which greatly simplifies the installation process.
First step. We put the toilet bowl in its place and make marks at the attachment points.
Markings on the floor for fasteners Second step. We remove the toilet and drill mounting holes in the marked places.
Third step. We hammer the dowels into the mounting holes.
Fourth step. Install the bowl. We insert the fasteners through special sealing gaskets. Tighten the fastenings. You should not pull too hard - you can damage either the fastenings or even the toilet itself. We pull until the sanitary ware is firmly attached to the surface. We close the fasteners with plugs on top.
Fifth step. We install the cover and seat. The instructions for assembling them usually come with the toilet, so look separately at this event we will not.
Sixth step. We connect the toilet to the sewer. The procedure depends on how exactly the toilet outlet is connected.

If the release is made into the wall, we work like this:
If a floor outlet is being installed, do the following:
Helpful advice! If the toilet connection is drain pipe is carried out using corrugation; in most cases, sealing can be abandoned, because the design of such an adapter hose itself is capable of providing a fairly tight fit.
Seventh step. We are installing the tank. Drain mechanisms, as a rule, are sold already assembled. If the mechanism is disassembled, reassemble it according to the manufacturer's instructions (assembly procedure for different models may vary slightly).
We take the gasket from the kit and install it in the water opening in our toilet. Place the tank on the gasket and tighten the bolts.
The most convenient way to install fasteners is as follows:
Eighth step. We connect the tank to the water supply using flexible hose. We turn on the water supply and check the quality of the system. If it leaks somewhere, tighten the nuts a little. We adjust the level of filling the tank with water by moving the float lower or higher.
Let the tank fill several times and drain the water. If everything is fine, we accept the toilet for permanent use.
Modern version installations. A special wall installation is used in which the tank mechanism is hidden. As a result, only the toilet bowl and flush button remain visible.
We install a wall-mounted toilet on the installation

The first stage is installation of the frame
We install a metal frame with fasteners. We attach the tank to the frame. The position of the frame is adjustable using brackets at the top and screws at the bottom. The frames are sold separately, have the same structure and are suitable for use in combination with any toilet bowls.
The assembled structure will have a height of about 1.3-1.4 m. The width should exceed the width of the tank.
Second stage - hanging the tank
The installation is carried out in compliance with the following recommendations:
- drain button place it at approximately a meter distance from the floor;
- between the fastening points we maintain a step equal to the distance between the lugs of our toilet;
- the drain pipe should be located at a height of about 220-230 mm;
- wall-mounted toilet hang at a distance of 400-430 mm from the floor. These are average values. In general, focus on the growth of future users;
- between the cistern and the wall we maintain no more than 15 mm distance.
The third stage – we install the finished installation
We first check the evenness of the wall using a plumb line. If deviations are detected, do the following:
Stage four - install the tank
First we connect the tank. The drain can have top and side outlets. Almost everything modern models tanks allow you to choose between these two options.
Important! When installing a toilet on an installation, it is better to refrain from connecting the tank using a flexible hose. will last much longer than a hose. In the near future, will you want to destroy the frame casing in order to replace such a hose in five minutes? That's it!
It is best to use plastic pipes for connections. All necessary fasteners are usually included with the tank. Separately, you only have to buy a panel for the drain buttons, and that’s not always the case.
We connect the outlet of our toilet to the sewer. The most convenient way to do this is with corrugation. We check the tightness of the structure. If everything is fine, turn off the water, temporarily disconnect the toilet from the flush and move the bowl to the side.
Important! The procedure for connecting the tank to the toilet and water supply may vary depending on the product model. We clarify these points separately and follow the manufacturer’s instructions.
Fifth stage – covering the installation
For this we use moisture resistant drywall thickness from 10 mm. It is recommended to fasten it in a double layer. First we do the following:
- screw the pins into the frame for hanging the toilet (included in the kit);
- We close the drain holes with plugs (also included in the kit) so that they do not become clogged with dust and debris;
- We make holes in the drywall for pins, pipes and a drain button.
We attach the sheathing sheets to the frame using special self-tapping screws. Keep the fastening pitch at 30-40 cm. The structure will have small sizes and weight, so there are no strict recommendations regarding the distance between fasteners.
We cover the drywall with tiles or finish it in another way at our discretion.
Helpful advice! Before tiling the box, we install a plug and cuff at the future location of the drain button. Usually they are included in the kit.

Stage six - installing the toilet
To do this, we connect the outlet of the bowl to the sewer hole and hang the product on pins (we installed them at the previous stages of work). These steps can be done in reverse order, as you prefer. Tighten the fastening nuts.
Important! The tile that will come into contact with the surface must first be covered with a layer of silicone sealant(you can install a gasket instead).
You can turn on the water supply and use the toilet for its intended purpose.
The installation instructions remain the same. Only the installation order of the toilet bowl changes. Work in the following order.
First step. Keep your knee position firmly in place. Metal fasteners will help you with this.
Second step. Treat the toilet outlet with technical ointment.
Third step. Place the toilet in its designated place. Trace the outline of the plumbing product and mark the holes for the fasteners.
Fourth step. Remove the toilet and install the mounting brackets from the kit according to the markings.
Fifth step. Install the bowl, press its outlet into fan pipe and secure sanitary product using bolts or other fasteners included in the kit.
Sixth step. Connect the tank to the drain. Installation and connection of this element is carried out in the same way as in the case of installation wall model toilet.
Seventh step. We insert the drain button into a pre-prepared hole in the casing, turn on the water supply and check the operation of the toilet. If everything is fine, we accept the product for permanent use.

Floor standing toilets for a long time were out of competition, but everything is changing. Owners modern apartments More and more people are choosing hanging models. This pleasure is not cheap, but this is practically the only drawback of this solution. But among the advantages of the design are its excellent design and ease of maintenance.
It is important that the installation of a wall-hung toilet is carried out in accordance with all the rules. We will tell you how and in what sequence the work is carried out, what devices will be needed to attach the bowl. Taking into account our recommendations, you can do everything yourself or supervise the actions of plumbers.
Home master can easily cope with the installation of a wall-mounted model if you understand distinctive features its designs.
The visible element of such a plumbing fixture is the toilet bowl itself. Its installation on the wall is carried out in two ways: using an installation and on concrete base. In our article we will look at both options.
A wall-hung toilet model is more expensive than a regular one floor option, but you can reduce costs if you install the product yourself
Strong and weak sides hanging type plumbing fixtures are listed, which describes in detail the varieties and design specifics, and provides guidelines for choosing the best model for you personally.
Wall design plumbing fixture can be roughly divided into three main elements, which will be discussed further.
Reliable steel frame (module)
The frame is the main element of the entire structure, which is attached to the floor and wall of the bathroom. It is the frame that supports the cistern and bowl. The quality of subsequent operation of the product depends on its reliability. After putting the toilet into operation, the structure will need to have a sufficient margin of strength to support the weight of an adult.
To secure the frame you must have solid foundation. Plasterboard walls cannot be considered in this capacity. The frame is equipped with a mechanism that allows you to vary the installation height of the toilet bowl in the range of 40-43 cm. To securely fasten the bowl, manufacturers recommend using strong pins made of steel.
In this photo, all three elements of the toilet design are clearly visible: a light blue frame, a gray-blue plastic tank with a flush button and a white bowl
The best models of support frames for hanging plumbing fixtures are listed, which we recommend that you familiarize yourself with.
Hidden cistern
The hidden fastening of this element, according to supporters of the wall model, is considered one of the advantages of the design. The material for its manufacture is very durable plastic. To prevent condensation from accumulating on the surface, the plastic is treated with styrene.
The tank has a flat shape, distinguished by a technological cutout on one side. This cutout is necessary for the drain key device. This hole has another purpose: it allows you to remove the drain tank fittings when performing repair work.
Another feature of cisterns suspended structure is economical system drain that such a model can be equipped with. Depending on the need, the drain dose can be 3 or 6 liters.
The bowl is a visible structural element
The bowl is chosen, as a rule, based on the personal preferences of the users. It is visible and must correspond general interior premises. In addition, it should be easy to use.
Exactly the toilet bowl, like visible element design, should fit organically into the interior of the room: it can even have a square shape
Most buyers prefer an oval-shaped product. Although there are round, rectangular and even square models on sale.
Fastening elements are part of the selected model and are included in its configuration. There is no need to purchase additional hardware for a wall-hung toilet. In addition, among the mounted models there are electronically controlled and numerous hygiene functions.
Intelligent types of plumbing fixtures with retractable nozzles for washing and drying, deodorizing and other actions need to be connected to a power supply. Their installation is complicated by eyeliner power line and setting up the system:
Image gallery
These long steel pins, running through holes in the frame and attached to the wall, are needed to hold the toilet bowl securely in place.
Connecting the necessary communications
First of all, we connect the sewer. For this connection, a black tap is used, which, as a rule, is included in the installation package. One end of this outlet is adjusted to the sewer pipe, and its other end is attached to the frame with special clips.
Water pipes should be located to the right or left of the module. The pipe should be connected to the structure using the existing one. threaded connection. To connect the water supply it is better to use copper or polypropylene pipes, and make the connection detachable.
Cold water can also be supplied to the tank using flexible hoses. Such hoses are more profitable in terms of price, but their fragility should be taken into account. And when replacing failed hoses, you will have to carry out expensive repairs, so the option with pipes is still preferable.
Don't forget to check how securely the drain container is connected to the water supply system. For this purpose, open the water supply tap. It is located inside the drain tank. After filling the container, everything possible leaks eliminated. This can be done without draining the water.
If, during the process of checking the correct connection of the toilet to the sewer or water supply system, leaks are identified, they should be carefully repaired
The connection to the sewer drain. To do this, put a toilet bowl on the studs and perform a test flush without finally securing the structure. After which the bowl is removed again and all identified leaks, if any, are eliminated.
Finishing work
At the next stage, you will have to sew up the niche using a moisture-resistant sheet of plasterboard, and then carry out the finishing work. Please note that we need moisture-resistant drywall, because regular drywall will quickly deteriorate under the influence of condensation.
For execution finishing works When installing a wall-hung toilet with installation, moisture-resistant plasterboard is used, which can be used in rooms with high humidity without reducing its quality
To cut drywall, you need to use a template, which should be included with the installation. It will allow you to correctly cut all the necessary mounting holes without damaging the material.
After installing the moisture-resistant sheet on its surface, you can fix finishing material. Ceramic tiles are most often used to decorate a bathroom.
Final installation steps
You can begin installing the visible part of the wall-hung toilet only after the tile adhesive has thoroughly dried.
The procedure for installing a toilet bowl:
- the drainage pipe must protrude 50 mm beyond the wall surface: it must be adjusted to this size;
- do the same with the pipe that leads to the sewer drain;
- both pipes are installed in the places intended for them;
- a large gasket, similar in shape to a truncated pyramid, is put on the studs that were fixed in advance, as well as on the pipes;
- the bowl is put on the studs and the pipes are attached to it;
- put rubber gaskets and plastic inserts in their places;
- put on and tighten the fastening nuts;
- The protruding parts of the rubber gasket are carefully trimmed.
Now you can drain the water from the tank, thereby checking the operation of the sewer drain. The installation height of the wall-hung toilet bowl relative to the floor can be adjusted by changing the position of the studs and retractable pins that are used to secure this element. It must correspond to the height of the toilet visitors.
The installation height of the bowl can be adjusted in the range of 40-43 cm, but the standard distance is 40 cm from the floor surface
The standard height is 40 cm, measured from the floor surface to the top edge of the bowl.
Attaching the flush key
The installation process is completed by installing the drain key. It is included in the basic package and can be mechanical or pneumatic. Usually this procedure does not cause any problems, since all the provided connections should already be brought to the surface of the wall.
There are special pins for a mechanical key, and tubes for a pneumatic key. All that remains is to install this element in its intended place and adjust its position. That's it: the toilet can be used.
Suspended model on a concrete base
A steel frame is expensive. In principle, you can do without it by building a concrete pedestal with your own hands, which will serve as a reliable foundation for the wall-hung toilet. This option is considered the most economical.
The diagram of the model on a concrete base includes: 1 – two rods for fixing the toilet bowl, mounted into the wall; 2 – concrete base; 3 – pipe for draining into the sewer
With this installation method, the drain container can either be mounted into the wall, with the drain button located outside, or placed above the bowl of the plumbing fixture.
Pre-installation procedure
Let's consider the option that is considered the least expensive. Let's prepare everything you need for work:
- concrete M200 - approximately 40 liters;
- boards for making formwork;
- threaded rods (length 50-80 cm, thickness 2 cm) – 2 pieces;
- washers, nuts, screws for woodworking;
- plastic pipe (diameter 11 cm, length 8 cm);
- drain coupling;
- Styrofoam;
- silicone sealant.
I think it’s worth repeating that the wall we have to work with must be permanent.
Step-by-step installation process
We fix rods in the main wall, onto the outlets of which the toilet bowl will then be placed. Let us remind you that we should get a stable and reliable design, capable of supporting a weight of 400 kg.
The next step is to install the drain coupling. At this stage, it is necessary to determine the height of the toilet in order to cut the coupling to the appropriate length.
Now we need to install the formwork. In order to mark fastening points on the formwork, you should determine the distance between the holes intended for fastening.
To calculate the length of the rods, you need to add up the thickness of the recess, which is approximately 15 cm, and the distance from the wall to the toilet bowl. To fix the rods in the wall, concrete adhesive is used - a chemical anchor.
This is what the structure looks like ready for the concreting process: the place where the drain will be connected to the toilet bowl is covered with foam plastic
When the formwork is installed and the installation of the pins is completed, the bowl should be installed in the place intended for it. Make sure that the mounting holes match the outlets, and the outlet hole matches the coupling drain.
The next step is concreting. It must be done by installing the foam in the place where it will be drainer. Remember that the concrete will finally harden only after 28 days.
After this, you can remove the formwork and make sure that in front of us there is a monolithic concrete block with pins coming out of it and an open, fixed coupling. A toilet is mounted to the front of the block, and a tank is placed on the base itself.
This is what a wall-hung toilet will look like after installing the bowl, and its tank will be installed on a concrete base
The procedure for installing the bowl to concrete base no different from installation floor-standing toilet. You need to install the bowl on the pins, tighten the nuts, connect and seal the drain. Lastly, a drain tank is placed on the concrete base.
As you can see, this installation method hanging model much cheaper and easier than installation work. But, to be honest, the result is not much different from a floor-standing toilet.
