Key Steps for Installing a Wall Shower Drain

1. Prepare the Slope and Frame

For the siphon, you need a slope of 1-2%. The front of the drainage system is then closed with screwed panels, drilling the necessary holes to bring out the connections for the taps. Complete the wall flush with the panel, proceed with plastering, then spread the screed respecting the necessary fan-shaped slope towards the drain. This step is critical to prevent standing water. Having the right garden supplies might not help here, but a good level and trowel from our home improvement collection will.

2. Install the Frame and Pipes

The frame that contains the wall drain also supports the supply pipes. Everything must be inserted into the wall before finishing and tiling. This is where you ensure everything is aligned and secure. Consider using a sturdy storage bench in your bathroom for extra space while you work, or a bathroom vanity to hide plumbing.

3. Waterproofing and Tiling

Remove the outermost part of the front protection of the drain, leaving that of the gully, and apply the waterproofing sheets that are part of the accessory kit, then tile the floor and walls. Geberit (www.geberit.it) is a common brand for these systems. For a cohesive look, pair your new shower with matching wall decor and a soft rug.

4. Final Adjustments

Once the tiles are laid, make the adjustments to the siphon inlet. This ensures a perfect seal and optimal water flow. Don't forget to update your bathroom lighting with options from our lighting collection for a bright, inviting space.
