Building codes for drying rooms?

[Karlruth]

We are planning to convert our sauna into a drying room.
Are there any specific regulations for drying rooms?

Do we need to have a wet room mat? wet room wallpaper? etc?

Can't it be treated like a laundry room, i.e. if you have a floor drain you should have a sealed floor extended 50 mm up the wall (I think it is) and optionally on the walls. If you are going to redo the walls, I would still paint with a water-resistant paint, e.g. http://www.beckers.se/Inomhus/Vara-produkter1/Vatrum/Vatrumstack/
