Hello everyone,
During the renovation of our old house from 1927, the bathroom is currently being done.
We have relocated it to the upper floor; the bathroom will be on a wooden beam ceiling (Holzbalkendecke, Schüttung, wood fiber insulation board, Rigidur dry screed).
Now it's about installing the shower tray. The installation situation is somewhat complicated; a corresponding hole was left in the floor for the installation of the drain pipes and the drain fitting. The drain fitting will be positioned between the beams in the wooden beam ceiling, so that the shower tray can be placed on the finished floor.
However, I am now concerned that over time the drain fitting might leak and water could run unnoticed into the wooden beam ceiling, causing it to start rotting. I asked the plumber whether some kind of additional sealing or protection would be possible. He said no and that the drain fittings are very reliable and usually do not leak. Is that really the case? Unfortunately, I have gradually lost trust in some craftsmen.
Furthermore, he wants to set the marble polymer shower tray directly on the finished floor (i.e., dry screed) in tile adhesive. Is that really common?
The floor is exposed to certain vibrations, and I doubt that this approach ensures long-term stability...
I am currently a bit unsure because the plumber and the tiler are clashing, and the latter basically questions almost everything the plumber does, and as a layperson, I can mostly only judge this with difficulty.
