Concealed installation of a wall-hung toilet: Overview + Video Mounting a wall-hung toilet for installation - step-by-step instructions and Video. Toilet bowls with installation are real aristocrats in the plumbing world. These devices are compact and convenient, because they are distinguished by an extraordinary design and a cost that is never sparing for customers. Moreover, the installation of a wall-hung toilet bowl on the installation is a rather difficult task that requires extremely careful execution.

And yet, despite certain difficulties, the number of adherents of toilet bowls with installation is constantly growing exponentially.

It is only important that each stage of the installation work is performed correctly.

The structure of a wall-hung toilet

A wall-mounted toilet is much more complicated than a monolithic or compact version. The installation is a high-strength metal frame that is installed inside the wall niche and securely fixed to the floor and wall. There is little space between the floor and the bowl of the wall hung toilet. Cleaning the sanitary facility is many times easier in such conditions, since there are simply no toilet legs.

A flat plastic water tank is attached to the frame, and then the required communications are brought to the niche, they are finished and the toilet itself is hung. The bowl remains outside, but the rest of the "filling" remains hidden behind the wall. A flush button is also displayed on the wall, which is usually located in the wall above the bowl. Even from such a short and concise description, it can be understood that the installation work of such a device is a rather laborious process.

Still, the models with installation have many advantages, and it is worth noting them:

  • Attractive design and aesthetic appearance - it creates a feeling as if the bowl floats above the floor.

  • Compact in size, which leaves plenty of room for the toilet in both large and small sanitary facilities.
  • Thanks to the absence of a leg, the cleaning process is greatly facilitated.
  • The design of the installation is universal, so you can choose certain elements to suit your wallet and taste.
  • Tank and frame breakdowns are extremely rare, and it is not difficult to repair or replace the drain button.

Bowls for wall-hung toilet bowls differ significantly in structure, configuration, shape, design, size, shades and other equally important characteristics, which leaves wide room for the selection of suitable plumbing fixtures.

But among the disadvantages should be noted the high cost. Taking into account the cost of installation, the cost of such a toilet is sometimes even twice the cost of a conventional floor-standing model. But manufacturers decided to take into account the increasing level of popularity of suspended plumbing, and therefore relatively inexpensive models appeared on sale. An additional disadvantage is that the frame and cistern, which are hidden in the wall, are not very accessible for repair work in case of anything.In the event of a serious breakdown, you may need to turn the entire wall around and re-do the finishing work on this area.

Installation and installation

Tools, devices and materials

In order to carry out installation work for a toilet bowl with a built-in installation, you need to buy the following elements in advance:

  • Wall-mounted toilet bowl.
  • Installation frame with plastic cistern.
  • Flush button.
  • Toilet seat studs.
  • A set of nozzles for connecting a bowl and a tank, etc.

Hidden installation of a wall hung toilet usually means that the installation purchased for installation will come with a flat plastic cistern, as well as adapters, fasteners, nozzles and a flush button. The kit also usually includes a special material that helps protect the structure inside the walls from the effects of condensation, and also reduces the noise level from the operating tank. When buying, be sure to check the kit so that, if necessary, you can immediately purchase all the missing components. The toilet bowl will also need to be purchased separately. The configuration and dimensions of the installation, like all other parts, are standardized, and therefore you can change / replace them if you wish.

For example, you can purchase a double flush button that saves water.

The presented diagram clearly shows the installation device with a plastic cistern and the required connectors, which is required in order to install a wall-hung toilet. To start the installation, you will also need a number of tools, and above all, you must have concrete drills and a hammer drill available, and the first must necessarily correspond to the fasteners. You also need a building level, a tape measure, spanner keys, a pencil for marking work, a knife for cutting drywall, and more.

The order of installation work for a wall-hung toilet

The schematic procedure for installing a toilet on an installation can be represented in the form of the most important steps:

  1. Make a niche in the wall of a suitable size.

  2. Bring the sewer to it.
  3. Install the installation frame.
  4. Bring cold water pipes to the flush point.
  5. Connect the toilet cistern.
  6. Close the niche, install the drain button and start finishing.

  7. Hang up the toilet, connect to the cistern, as well as to the sewer.

You may also need a certain amount of drywall - for finishing and installation work. Each stage of the installation of a wall-mounted toilet requires a competent approach and close attention. The operational life of the device, the nature of breakdowns and their number will largely depend on how well the installation work was carried out.The results of even small errors that were made during the installation process may not be obvious immediately, but only during operation.

Sometimes repairs turn out to be an extremely costly and time-consuming task, and for this reason it is worthwhile to immediately install all the elements of the device correctly, since alterations will be more expensive for themselves. More details on the installation work for a wall-mounted toilet are presented in the video tutorial.

Niche for installation

Mounting a wall-hung toilet on an installation is impossible without preliminary preparation, as well as creating a niche. For the latter and the installation of the installation, only a wall with good bearing capacity is suitable. Believe me, the installation frame is capable of supporting up to 400 kg, and part of the load will go directly to the wall.

For this reason, it is worth putting a hinged toilet against a strong wall, and drywall will definitely not work, as it can simply collapse.

So, for installation work with installations, you need to hollow out a niche in the wall with the following parameters:

  • Height - 1 meter.
  • Width - 0.6 meters.
  • Depth - from 0.

    15 to 0.2 meters.

By the way, sometimes it is not so easy to fulfill the depth requirements, and in this case the niche should be made to the full possible depth, and its deficiency should be hidden with a finishing layer and drywall. this way, you have room to experiment with design and interior decoration. For example, you can make a built-in cabinet in the space between the protrusion that appears and the wall, or hang open shelves.

But the idea with the usual installation of the frame along the wall, and after its further sheathing with drywall does not make sense at all. In this case, it will be cheaper and easier to put the most ordinary compact toilet in the same place, which will take up as much space as the previous one (or even less).

Concealed installation of a wall-hung toilet: Overview + Video If the sanitary unit has a niche for sewer and water supply lines, then it makes sense to install the installation frame in it ...

Residents on the upper floors of apartment buildings sometimes even install a fan riser in a niche, and a certain part of it is cut off and an air valve is installed in the place where the outlet to the attic is located. In certain sanitary facilities, a communications niche is provided according to the project. You can also use it for the installation work of the installation, but certain alterations may be required, for example, changing the position of the pipes of the water supply system and displacing the sewer riser. If you have no experience in performing such operations, then it is best to consult with specialists or even entrust them with the implementation of this part of the installation work.

Sewerage connection

Before installing the frame, you should first take care of how to properly bring the sewer pipe to the installation site.

You need a pipe with a diameter of 10 cm, and you should lay it as close as possible to the floor surface, and also maintain the correct slope (2 cm per linear meter). The place where the connection will be made should be 25 cm from the center of the wall niche. An oblique bend should be put on the horizontal part of the pipe, the angle of which is 45 degrees. After all these operations have been completed, you can proceed directly to the installation installation process.

Settings of the frame with a tank

Four points are provided for installing the installation frame, and in two places (points) the legs of the frame will be fixed to the floor, and in two more places the frame should be fixed to the wall with brackets.

In this case, it is imperative to use a building level so that the structure is perfectly level and strictly vertically / horizontally. To do this, we recommend checking the position of the frame from all sides. If the installation is installed even with a slight bias, then even malfunctions may appear in the operation of the internal mechanisms, and this will inevitably lead to the structure being broken. Adjustable feet should be used to level the frame vertically.

The horizontal position should be set using the wall brackets, and the position can be changed as you require.

After everything has been accurately set and fixed, you can start screwing it to the wall. Do-it-yourself installation of a wall-hung toilet requires that the frame be stable, and for this you can even additionally cement the legs. A screed layer of 0.2 meters in height will be more than enough, but such a measure is not required. The height of the legs from the frame, which is designed for a wall-hung toilet, can be adjusted.

This will make it possible to set the structure strictly horizontally in level.

At the bottom of the installation there are a couple of holes that are needed for further installation of the wall-mounted toilet bowl. The distance between these holes and the floor should be about 0.3-0. 4 meters so that the toilet bowl can be hung higher from the floor surface.

Special pins will be installed in such holes. They should be inserted all the way into the wall and secured with special nuts, and the studs are needed in order to hang the toilet. Insert them into the corresponding holes on the frame and attach to the wall surface.

Connecting all communications

Here you should start with the sewerage system, and usually a special black outlet is included with the installation which is for this connection. It needs to be fitted to the sewer pipe, and the other side of the outlet must be attached to the installation using special clips.

The connection to the water supply is made on the left or right side of the installation. The water pipe must be connected using a threaded connection that is already in the structure.Experts advise using only modern pipes that are made of copper (because it is durable) or polypropylene, as well as installing a convenient detachable connection. Even the most ordinary flexible hoses can be used to supply water to the tank, and such a simple (and most importantly, inexpensive) option could be ideal, but its service life is shorter than that of pipes, and therefore it is necessary to take into account this circumstance of complex repairs for replacement ..

Concealed installation of a wall-hung toilet: Overview + Video At this stage, it is required to check the reliability of the connection between the water tank and the water supply system. To do this, you need to open the water supply valve, which is located inside the tank, and then fill the container. Next, check each connection for leaks and troubleshoot if necessary. In this case, it is not at all necessary to drain the water.

Checking the connection to the sewer system can be done as follows - attach the bowl to the studs and perform a test flushing, while not securing the structure. After that, you should remove the bowl from the mount, check for the presence or absence of leaks, and then proceed with the installation.

Finishing work

If you have installed the installation correctly, and the tank does not leak, you should sew up the niche with a moisture-resistant drywall sheet and complete all finishing work ...

It is recommended to take exactly a moisture-resistant and double sheet of drywall, since ordinary material will soon be damaged due to contact with condensation. In order to correctly cut all the mounting holes in the sheets and not spoil the material, you should use a template for cutting. It usually comes bundled. When the installation is installed and all the required communications are connected, the niche should be sewn up with a sheet of moisture-resistant drywall, on which finishing work will be carried out in the future. In the bathroom, most often the walls are tiled with ceramic tiles.

The rest of the work on the installation of the hanging toilet can be started only when this stage is completed. Also, it will not be a mistake to completely finish the repair of the sanitary unit, and only after that start installing the hanging toilet.

Installation of a wall-hung toilet

In fact, installing the toilet itself is not something super complicated, on the contrary, when almost the entire scope of work has already been completed.

But first, it is recommended to wait for the layer of tile glue to dry completely, and then you can install the toilet bowl as follows:

  • Adjust the dimensions of the pipe from the drain tank, which should protrude 5 cm beyond the wall.
  • In the same way, cut the branch pipe that is intended for draining the sewer.

  • Install the nozzles in the places they are intended for.
  • Put on the previously installed pipes and studs special gaskets of a large size, they are somewhat similar in configuration to a truncated pyramid.
  • Put the toilet bowl on the studs, securely connect with the pipes.
  • Install plastic inserts and rubber pads.
  • Install and tighten the retaining nuts.

  • Cut off the protruding part of the rubber gasket.

And do not forget that hanging the toilet on the installation, its connection to the cistern and the sewer system is carried out after all finishing work is completed! after that, you can check the operation of the sewage system, drain the water from the drain tank into the bowl. To adjust the height of the bowl above the floor surface, you need to change the position of the retractable pins and pins that were designed to hang the toilet bowl. In this case, you should focus on the growth of the visitor. The universal height is a distance of 0.

4 meters from the edge of the bowl to the floor.

Installing the flush button

At the end, all that remains is the installation of the flush button. It can be mechanical and pneumatic. The installation operation is simple, since all connections are already provided and ready for installation, as well as lead to the corresponding hole on the wall. To install a mechanical type button, you will need to install special pins, and then adjust their position.

The pneumatic model is connected with the necessary pipes at the installation and immediately after that it will be ready for use.
