Is underfloor heating necessary in the shower? What do you think about it?

Good morning!

The floor heating under the shower is of course more effort for planners/plumbers/screed layers. Therefore, people often argue with lime etc. – in my opinion, complete nonsense! See also experiences in the thread.

What you have to consider, however, is that the immediate heat at the shower channel CAN dry out the siphon and it might start to smell!

PS: For us, of course, with floor heating under the shower in the bathroom and WC; however, with distance to the channel and everything well wrapped/insulated.

With us, the argument of the heating and sanitation company was also the accelerated drying of the siphon. We accepted that and have no heating loops in the shower. We now (move-in a few months ago) do not find this negative, as the floor feels immediately warm after water.

We also do not have underfloor heating in the shower and I was initially afraid because of the floor being too cold but it was completely unfounded. Firstly, the floor is only minimally colder than the rest of the floor in the bathroom and secondly, it warms up immediately when you turn on the water and also afterwards when drying off. I also don't know if the slope towards the shower drain would have worked for us.

So with my shower, I first have to step INTO the shower in order to even be able to turn on the water...

That's exactly why I redesigned our shower... at least the faucet has to be positioned so that I can turn on the water first and then step under it when it's nice and warm... unfortunately, that's often forgotten

What you have to keep in mind, however, is that the immediate heat on the shower drain CAN dry out the siphon and it may start to smell!

Dreamy. Of course, siphons of walk-in showers can dry out faster. These things are also much shallower. From my own experience, I can only report negative things after a 5-week absence. If you shower regularly... Well. I would always have heating loops installed in the shower as well due to the temperature regulation of the bathroom...

The siphon certainly dries hardly any slower if there is no underfloor heating. We also have underfloor heating in the showers and no problems with the drains. The underfloor heating only heats up to a maximum of 10 degrees more than room temperature.
