Construction of a 144 sqm bungalow in Fichtenwalde (near Potsdam)

There is also a technical reason to refrain from it. For walk-in showers, the screed must be installed with a slope. Then the minimum coverage over the heating pipes, usually 45mm, is often not formally achieved there. I have it in my place, so the screed had to be done on site there. Whether the minimum coverage was maintained, I don't know, and I don't care.

There is also a technical reason to avoid it. For walk-in showers, the screed must be installed with a slope. Then, the minimum covering over the heating pipes, usually 45mm, is often no longer formally achieved. I have it in my place; the screed had to be done on site because of that. Whether the minimum covering was maintained, I do not know, and I don't care.

jepp, with that argument my request for underfloor heating in the shower was unfortunately also rejected back then.

That is of course nonsense. You simply leave out one layer, or 3-4 cm of styrofoam insulation in this area. And then you don’t have cold feet when you jump into the shower

There were also problems for me regarding the demarcation of the trades and the subsequent warranty.

Underfloor heating: heating engineer
Screed: screed layer
Shower including slope and screed underneath: tiler.

The general contractor completely resisted this because the boundaries were no longer clearly traceable.
