ᐅ Underfloor heating beneath the bathtub and shower

Hello,

What is the standard nowadays? We want to do without individual room controls and install a brine heat pump that is sized as optimally as possible and operates efficiently.

To achieve these goals, is underfloor heating nowadays also installed under the bathtub and shower? Does this cause any issues (for example, the bathtub not being installed on the raw floor but on screed or something similar)?

How have you solved this in your homes?

Thank you!

We have underfloor heating in the showers. Otherwise, I think it would be too cold on the feet...

We don’t have any under the bathtub!

Hello

My bathtub, or rather the Styrofoam support, rests on the concrete. This makes getting in very comfortable. And thanks to the Styrofoam support, the tub is not cold either.

From a purely practical point of view, nothing. But you won’t find anyone who will build it with a warranty like that.

I’ve also heard that you can’t install underfloor heating beneath a shallow shower tray because it can expand or shift, and the heating engineer wouldn’t do it.

The heating engineer would only install underfloor heating under the shower area if you have a level-access tiled shower... is that what you mean by warranty?

Hi,
having it in a walk-in shower makes sense, but what is the point of having it under the bathtub?

Surface area for heat transfer – the goal is not to create a warm bathtub but to heat the screed.
If nothing is installed under the bathtub, the heating is done by the loops positioned next to it.

If the heating pipes are not embedded in the screed, they obviously have no protection and could be damaged. That’s why I said no one would do it with a warranty, even if it might be possible and reasonable.
