Underfloor heating in the shower?

We have it in there too, but it’s just the pipes from the bathroom that were included. It dries faster, it’s a nice feeling when the underfloor heating is activated, that you don’t really feel the "extreme" temperature difference. When showering itself, you won’t notice it, because the water heats the spot very quickly.

I can absolutely agree with Sebastian’s statements. You should simply use cement screed throughout the entire bathroom, then there shouldn’t be a "transition" from the shower to the rest of the bathroom.

Hi,

I would also strongly recommend this:

You should simply use cement screed throughout the entire bathroom, then there shouldn't be a "transition" from the shower to the rest of the bathroom.

To be honest, the site manager's statement that a different screed is used in the shower than in the rest of the bathroom makes me suspicious. Surely they don't want to use anhydrite screed in wet rooms?!?!?

I think that's a really bad idea...

Just use cement screed; it works everywhere and can even survive moisture damage if necessary. You can knock out and dispose of anhydrite screed right away!

Best regards,

Andreas

I would like to have that physically explained

When evaporating, the salts remain ("lime"), the warmer the surface, the more water evaporates. Without heating, the proportion of water draining off is higher. Whether this is practically relevant depends, among other things, on the water hardness and the housewife .

The site manager certainly means that the screed in the shower is applied separately or recessed. This is because a slope is incorporated. Then a joint is created to the main screed.

Exactly! Unfortunately, he is currently on vacation (well deserved), but that's roughly how he explained it to me. The plumber, on the other hand, said nothing negative about it.

We also heated the shower. The tiles were laid without an expansion joint. According to the heating technician and tile installer, this should not be a problem because the main screed and the shower screed are heated with the same output. It is basically a problem when different heating loops with different set temperatures meet, then an expansion joint must be installed. That’s how I understood it at the time, although the discussion was not about the shower in our case, but about the hallway, living and dining area. We have no expansion joints.
