Tiling
Install the tiling frame set.
Cut holes in the tiles for water connections, and apply the tiles to the wall.
Caution
Do not cut the PEX Hoses, they need to stick out for coming installation steps.
Do not use a drill larger than 30 mm in diameter for the tiles; otherwise, the diverter will not fully cover the holes.
Make sure the tiles do not overlap the grating, allowing it to be removed.
Note
The floor tiles must be level with or higher than the frame. To achieve this, they must be at least 8 mm thick.
Apply silicone sealant around the floor drain and in the rest of the bathroom.
