Such a sanitary element as an installation fits perfectly into the concept of modern renovation. Many, according to an unspoken law, close all lines and communications from prying eyes, therefore, given the fact that the prices for creating an installation are acceptable, hidden cisterns began to be more often installed in household bathrooms.

But still, despite the fact that the installation of such a part is quite simple, not everyone knows how to sheathe an installation for a toilet bowl with plasterboard, while some have difficulties, since it is still necessary to install and a toilet that requires a solid base. In fact, there is nothing complicated in this, it is just necessary to adjust the finishing technology, since the frame will be used.

Toilet installation - what is it

What is a toilet installation and what are its advantages over standard bowls? The point is in the device, since this structure is a system hidden in the wall, which ensures the operation of the device, and only the bowl is externally visible, which is attached to the plasterboard wall.

This element consists of a steel frame on which the cistern is attached, and it is additionally equipped with retractable rods that adjust the height, the outlet for the water drain and the panel for attaching the toilet. All this can be easily placed in the space behind the wall.

This compactness is ensured by the shape and features of the cistern. The latter is flat, and its plastic case is enclosed in an insulating shell in order to prevent the formation of condensation. Of the entire structure, only a button remains on the outside for draining water from the container.

In addition, this device has a margin of safety and is designed for a load of 4 centners!

What are the advantages of installing in a bathroom? The main advantage is compactness, since the design itself is not small, and provides the functionality of the device imperceptibly for others, and the toilet bowl is close to the wall. In addition to saving space, such an orientation in space helps to facilitate cleaning, since access to wall and floor finishing is open. But to obtain such quality, all technological rules and regulations should be observed, as well as good material should be selected.

Sheathing process

Tools, materials

In order for the plasterboard installation to be hidden in the wall, plasterboard finish, which is assembled on the basis of a frame made of a metal profile, is ideal. For this reason, certain materials will be required, as well as a set of tools that are suitable for work on drywall.


Everyone knows that there are three types of drywall panels that should be used for finishing work on the surface in different conditions.To decorate the walls in the bathroom, due to the specification of the room - high humidity, a special material is required that can withstand such influences. The ideal option would be to use a special type of material, namely moisture resistant drywall, which has a green color.

How to sheathe a toilet bowl with plasterboard? Instruction + Video Please note, that the peculiarity of moisture-resistant material is that, in addition to gypsum inside, it acts as a filler antiseptic additives are used that prevent the formation of mold and mildew at high humidity levels, and also prevent the accumulation of water inside the skin layer.

With an additional layer of finishing (PVC panels, decorative plaster, tiles), the material gets excellent waterproof characteristics, and in terms of strength, such green drywall will not be inferior to other analogues.


For the assembly of the frame on the wall for covering the toilet bowl with plasterboard, it is recommended to use only a metal profile with a good zinc coating, which has anti-corrosion properties. The use of wooden slats for assembling the base is not allowed, since this is not facilitated by the specifics of the room (high humidity). Profiles are needed in two types - guides (marked with UD) and rack-mounted (marked with CD). With the help of Latin letters, you can mark products according to the notation system from the Knauff company, and there are also domestic designations with the abbreviation PN (guide profile), PP (ceiling profile) and PS (rack profile). For fastening frame elements to the bearing wall and among themselves, hardware is used.


These materials can be divided into the following two groups:

  • For fixing plasterboard sheathing.
  • Assembly and installation fasteners for the frame.

For the first case, use special self-tapping screws for fixing drywall, the length of which is at least 1.8-2 cm and thickness of 0.45 cm.

Such parameters are required so that the screwing in of the tip is at least 0.5 cm in profile and with a secure fixation of the sheet. The screws must be necessarily with an anti-corrosion coating, and the assembly of the frame will be done thanks to two types of fasteners - dowel nails and small screws for metal (fleas, bugs). The guides are the first to connect the base to the load-bearing walls. The second type of fasteners provides the connection of metal elements with each other.

Another element of the frame is a straight suspension. This is a perforated metal plate, which can be additionally attached to the already assembled structure to the wall, due to which greater rigidity will be achieved. But before buying all the necessary materials, it is worth planning everything and making a markup of the future structure for a hidden installation.

Installation of the frame for flush-mounted installation

First, it is worth doing all the rough finishing work, and also check how high-quality the communication lines are, so as after finishing is completed, full access will be possible after dismantling for the plasterboard structure. When everything is done, you can start assembling the frame base for cladding the installation in drywall.

  1. Usually on the wall, on which the installation will be, there are communications, namely water supply and sewerage. They must be hidden with a box. Because of this, it is best to hide the entire surface under a drywall trim. First, you should make a markup for the frame.
  2. The plasterboard installation for a toilet bowl should be sheathed using fixing pins, therefore, the sheathing must be made almost at the same level as the installation.

    When marking the lines for the guide profile on the ceiling and floor, the bead should be done so that the frame is located close to the device.

  3. A guide profile can be laid at the mark, which will be rigidly fixed to the bearing surface when using dowel nails. For fasteners, holes should be drilled through the profile, which will have a pitch of 35-40 cm. After that, you can drive dowels into the holes.
  4. The rails should also be fixed on the sides, and the fixation will be ensured in the same way.

    Under the frame racks on the wall, you should fix straight suspensions of 3-4 things on each profile.

  5. Install the frame posts vertically into the rails. Their number will be determined by the volume of GK sheets (at least 3 racks for each panel), while on one of them adjacent elements for cladding will be joined. The racks are fixed with bedbugs to the guides (2 self-tapping screws on each edge).
  6. Also, straight suspensions are bent to the racks, which also need to be attached with bedbugs, and cut off the excess ends or bend inside the frame.

    After that, we lay cross rails from the CD profile between the racks, where you need to cut the side shelves to the fixing length. The installation of parts is also carried out by bedbugs.

  7. A sighting hatch should be installed to access important areas such as valves, hatches, etc. Under it, in the frame there will be cross members and posts made of CD profile.

The finished base can be sheathed using drywall, but take into account some peculiarities.

For a better understanding, watch the video of installing the frame.

How to sheathe with plasterboard

In fact, the technology of cladding using drywall sheets is almost the same as the standard, but there are some peculiarities. It is important to understand that when cladding hidden plumbing, you should use a double layer of material!

  1. How to sheathe a toilet bowl with plasterboard? Instruction + Video First, install a drywall sheet on installation for lining the toilet.It is necessary to make holes in it for the fastening pins of the structure in advance, and the installation of drywall will be provided with self-tapping screws, which are screwed in in increments of 25-30 cm. In this case, the caps of the self-tapping screws should be sunk into the surface, but at the same time do not damage the drywall sheet.

    Please note that drywall will also be attached to the installation frame, and for this, holes for self-tapping screws should be drilled in the steel corner of the structure.

  2. After the main panel is installed, you can start attaching the rest. The sheets must necessarily be located with a small gap of up to 0.3 cm, and from the ceiling and floor at 0.5-1 cm.

After the sheathing is finished, you can start finishing work. In certain cases, it is possible to sew up the installation in the form of a box, which is made using frame technology.


The finished surfaces should be prepared for finishing work, especially if you plan to use a tile over drywall as a cladding.

  • First, you should seal the joints between the sheets of drywall. To do this, make a putty mixture with which you want to grease the gaps, and glue the serpyanka mesh on top.

    After that, such areas should be once again covered with a thin layer of plaster (0.1-0.2 cm).

  • When the joints are dry, wipe them. The entire surface should be primed and plastered with a layer of gypsum mixture with a thickness of 0.

    1-0. 2 cm.

  • When everything is dry, rub the plane with a float.

If the installation was made as a plasterboard box, then its edges should be additionally reinforced with corners (plaster). The finishing process for such a structure is the same as for wall decoration.

such a scheme can be changed, but everything will depend on the conditions in which the installation was performed, but it is advisable that all the nuances are planned, and then the installation and finishing of plumbing will not create problems for you during use.
