Radiant heating under shower floors

Ron Miller_2

Is there a specification for running hydronic radiant tubing in the wet-bed subfloor below the shower pan liner?
Will the liner be affected or lose its warrantee.

why?

I don't really see the point here, walls sound good but the floor?
I think its typical to turn the hot on full blast and go get a cup of coffee waiting for the hot water. by the time you step into the shower the floor is warm.
liner should be fine.

Say...

...does the local water department send you a gift basket every year, along with a note along the lines "to our best customer?" LOL

But seriously, nothing wrong with a recirculation system in a new house to spare the need for letting the water get hot.

For me, the bigger issue would be to determine whether the limited floor area in most bathrooms is sufficient to keep the place warm. That in turn would drive wall-based installations, like the ones in the vestibule of our house.

Bathrooms can also benefit from towel warmers that lead a double life as a second-stage heating system.

Hello Constantin...

So Ron Miller, the way I see it, there is nothing wrong with putting radiant in a shower floor, or a shower bench and especially a wall. But like Constantin said, make sure of where your loses are. Walls are great to make up some supplemental and so are towel radiators(I hate calling them towel warmers, makes them seem useless).

We have installed radiant heat under the pan liner on just about every job with a site built shower. Every custom home usually has a recirc. line so it is nice to have that floor warm when you get in but it also makes for a nice dry shower floor soon after the shower

Shower radiant

We always tube the shower floor. then we pour 3/4" of gypsum concrete over the tubes and let the plumber install the shower pan on top of the gypsum concrete. It is sloppy trying to install a membrane over the uneveness of pex tubing alone.

Here we go again

There are alot of ways to do this. We find the simplest is to run Climate Panel or Quick Track into the shower and then put your copper pan or rubber membrane right over it.

Works fine AND you don't run the water for ten minutes

Here's a print

I made up some time ago and recently computerized it.

I LOVED my heated shower floor.
