Hello everyone,
Since my parents are a bit hesitant to consult an expert and I don’t really have much knowledge on this topic, I’m just going to ask you all—maybe someone knows something 🙂
My parents have been planning for some time to build an extension to their private home and install a sauna in this extension. Now, a sauna exposes the walls to a significantly different type of moisture than a regular bathroom (it’s warmer, of course) – how is the best way to insulate the walls to prevent mold from forming on the inside?
I’ve tried to read up on this via Google, but I haven’t really found a clear answer 🙁 For individual products like mortar, plaster, concrete, etc., there is always mention of capillary water absorption/water absorption coefficient and something about water vapor – but I don’t really understand what that means or whether a high or low value is good or bad.
Logic tells me that exposure of a wall to moisture and air will lead to mold over time, but maybe it works in a completely different way...
I also asked about this once at a home improvement store, but the salesperson looked at me as if I was crazy...
Could someone please explain this to me? :/

Installing a sauna and ventilating it properly. Hang up a humidity meter for about 3 euros and monitor it.
Possibly retrofit an exhaust vent later.
Most of the moisture during pouring stays inside the sauna and gradually dissipates as the heater cools down. Otherwise, every sauna would develop mold on the interior surfaces.
What helps: ventilate well and heat the room properly.

We are currently planning to include a sauna and would simply leave the door open after using it, relying on the rest of the ventilation system with heat recovery. A sauna produces less humidity than taking a shower, so where is the problem? If, for physically impossible reasons, excessive humidity does occur, you can always open the windows or set the ventilation system to full power.
