Dress up a wall installation

According to modern building standards, sanitary facilities are installed in pre-wall installations. Subsequently, these elements are walled or clad and then plastered or / and tiled. Following you will find instructions for dressing a pre-wall installation for drywall applications.

Pre-wall elements meanwhile in all domestic sanitary areas

The installation of sanitary facilities in a pre-wall element has long been a recognized building standard. All sanitary facilities in the bathroom and toilet are housed behind:

  • Bathtub inflows and outlets
  • Water inlet and drain for showers
  • sink installations
  • bidets
  • toilet installations
  • urinals

Differences in the pretext components

At first, of course, the pretext installations differ in their size. For bathtubs they can be very small, in combination with a shower-wall installation but also ceiling high. Under "Installing flush-mounted cistern" you will receive installation instructions for on-wall installations for toilets. But also the increasingly popular urinal assembly we explain here in detail including all the peculiarities.

Different versions of wall installations

For the pre-wall installation executions different models can be distinguished:

  • Surface-mounted wall installation
  • Flush pre-wall installation for wet construction
  • Flush pre-wall installation for drywall

The surface-mounted pre-wall elements differ mainly in that they neither plastered nor disguised (drywall) must be. Instead, the pretext element comes in a cabinet-like and attractive look. Under "Cement cisterns" you get a derivation for disguising a wet construction pre-wall installation. Below we show you how to disguise a pre-wall installation for drywall construction. Whether toilet, sink, bathtub, etc., plays a minor role.

Suitable drywall panels for dressing

Some pretext elements already come with a panel that can be tiled directly. As a rule, however, corresponding damp-room panels must be purchased separately and then mounted. However, it is strongly advised not to use conventional plasterboard. Instead, you can use wet room panels, glass fiber reinforced and OSB panels. OSB and wet room panels can also be combined, as the pre-wall installation should always be double-planked when dressing.

Step-by-step instructions for disguising a pre-wall installation

  • wall installation
  • suitable plates for dressing
  • Stud (metal, wood)
  • Drywall screws
  • Grout, suitable for damp rooms (plastic-coated)
  • Sanitary or wet room silicone
  • drilling machine
  • various drills (stone, metal, etc.)
  • mixing paddle
  • Kreislochsäge
  • possibly jigsaw
  • Cordless Screwdriver
  • spirit level
  • Meterstab
  • mortar bucket
  • Trowel or trowel for grouting
  • silicone syringe

1. Preparatory work

First, of course, you need to attach the pretext element. For this, follow the assembly instructions of the manufacturer.

2. Set up the stand

The stands can be bolted directly to the frame of the pre-wall installation as well as to the walls (depending on how wide you want to build a pretext)

3. Prepare drywall panels

The holes for the water installation and fixtures (suspended sinks, hanging toilets, etc.) are measured and drilled before attaching the panels.

4. Dress up with the plasterboard and OSB panels

Now you can screw the cladding panels directly onto the stud frame. Make sure that the screws are always screwed sunk. With double planking, the panels are to be moved so that the joints are offset accordingly.

5. Have the paneled wall installation installed

Then the assembled drywall panels are grouted. Proceed as with grouting an ordinary drywall. Further information and tips on plasterboard grouting can be found here: Trockenbauwand Ratgeber. The quality level for grouting will of course depend on how you want to continue working on the now professionally clad wall installation (laying tiles, smoothing, plastering, etc.).

6. Fill with expansion joints

Finally, you can now grout and remove the expansion joints with silicone.
