ᐅ How can mold growth in the shower be prevented through building design?

Hello!

In my current home, mold repeatedly forms in the shower. The bathroom is tiled and has a floor-to-ceiling window. Opposite this window, the shower is located in a corner niche of the interior walls. There is a full-height radiator that can be used for hanging towels. The return flow of this radiator runs through underfloor heating. So the room can be adequately heated.

Black mold keeps appearing in the shower, and I would like to know how I can prevent this in my new build through structural measures...

I do it mainly because of the lime.

I don’t consider it overdoing it since I’m not doing any plastering and I always have a towel in hand anyway.

If water stays anywhere for hours, even just small droplets, mold is very likely.

Now you’re exaggerating a bit. 🙂

No, that’s not an exaggeration.

Or why do you think some old window putty develops mold? Certainly not because it’s dry there.
It’s the same with the joints in the shower – whether silicone or grout. Constant moisture that never dries out eventually leads to black mold.

I noticed that you also started the thread about fixed windows.
I would avoid them too if there is no mechanical ventilation system installed (I’m assuming such a system won’t be included in your cost-saving approach). Windows need to be operable for ventilation.
