ᐅ Linear drain for level-entry shower with underfloor heating

Our plumbing expert said that there is a risk with both options—shower tray or fully tiled shower area. With a shower tray, the risk comes from leaking silicone joints at the edges—and my parents recently had exactly this problem. If the work is done professionally (sealed twice), the risk should be just as low as with a shower tray.

Our heating installer recommended it to us. He said the low temperature of the underfloor heating wouldn’t be sufficient to comfortably warm a bathroom, so every extra square meter (sq m) of heating surface is a benefit.
From experience with our current bathroom, I can confirm he is right – the room isn’t warm enough with just the underfloor heating, at least not for kids. Without the towel radiator, the bathroom wouldn’t be as warm in winter. It runs on a timer only in the mornings and evenings.

That really depends on the spacing of the underfloor heating pipes...
It’s not true that every square meter counts...

Our architect also advised against it to ensure long-term reliability of the shower’s waterproofing.

With underfloor heating, the structure expands and contracts too often, which can cause problems.

In both houses, it was installed tightly spaced in the bathrooms. And as you can see at my parents’ place, even a shower tray does not prevent damage.

Certainly not, but why increase this risk further with underfloor heating?

Why should the risk be increased? Because of the temperature differences? The low-temperature heating system operates with such a low supply temperature that nothing happens because of the heating. So, I’m not worried about that. You could also see an advantage in the underfloor heating: the shower dries faster – so the grout isn’t exposed to water for as long, and the risk of mold is also reduced (even though we have ventilation in the bathroom, the shower itself is almost like a room within a room).

The screed in the shower area and bathroom is different from the rest of the rooms in our house. A professional is handling the tiling work and installations, and we also have ventilation.

I have always found underfloor heating in the bathroom very comfortable and believe the shower, whether tiles or grout, will not be affected by it.

I will report back.
