Floor-level shower drain with underfloor heating

2015-02-08 22:52:07

Our plumbing expert said regarding the question of whether to use a shower tray or tiling that there is a risk with both options. With the shower tray, the risk comes from leaky silicone joints on the side – and this was exactly the problem my parents had recently. If it is done professionally (sealed twice), the risk should be just as low as with a shower tray.

Not yet, but soon. Our heating installer recommended it to us. He said the low temperature of the underfloor heating would not be sufficient to make a bathroom nicely warm, so every extra square meter for the room is a plus. And from my experience with our current bathroom, I can say he is right that the room is not warm enough with just the underfloor heating - at least not for kids. Without the towel radiator, it wouldn’t be so nicely warm in the bathroom during winter. The latter runs on a timer only in the mornings and evenings.

That really also depends on the laying distance of the underfloor heating... Not every sqm counts...

Our architect also advised against it to have long-term joy with the tightness of the shower.

With underfloor heating, the construction expands and contracts too often and that can lead to problems.

In both houses, closely installed in the bathrooms. And as you can see at my parents' place, even a shower tray does not protect against damage.

Certainly not, but why additionally increase this risk through underfloor heating?

Why should the risk be increased? Because of the temperature differences? The low-temperature heating system operates with such a low flow temperature that nothing happens because of the heating. So, I’m not worried about that. One could also see an advantage in the underfloor heating: the shower dries faster - as a result, the joints are not "under" water for so 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 other rooms in our place. The tiling work and installations are done by a professional for us, and we also have ventilation.

I always found underfloor heating in the bathroom very pleasant and think the shower, whether tiles or grout, will not suffer because of it.

I will report back.
