I have some questions about the situation...
We currently have %-floor in the basement, i.e., a thin uneven concrete floor, (this was done during the tough years because cement was expensive).
The floor is between 3-5 cm thick... As far as I understand, it doesn't have any load-bearing function in the rest of the foundation...
The foundation consists of concrete walls, which should go down significantly further than the floor, in other words.
We now want to furnish one of the rooms to have a relaxation/bathroom area... i.e., Shower/sauna/hot tub... + laundry and drying.
The question is, is it okay to build a regular wooden joist structure with insulation and asphalt boards underneath, chipboard and tiles on top... With some type of underfloor heating. Water or electric?
What I'm wondering is how it will work with moisture in the foundation. Of course, there is no ventilation under the current floor.
My thought is to first dig down a bit, lay plastic sheeting against the ground, then fill up with leca balls.
Then further build up with the wooden joist structure...
I know it might be better with concrete, but according to my thoughts, it would be much more expensive and you wouldn't be able to divide the work/purchase of material in the same way...
Those of you with similar, Thumbs up or down?

If you are going to dig up the old floor anyway, I see absolutely no reason to start building up with wood materials in a basement floor for a wet room! Make a proper concrete floor with insulation underneath and with embedded underfloor heating pipes, and then tiles on the surface. The cost of concrete is really not large compared to everything else in a basement bathroom project.
Thank you for the response. b&q Sure, I'm thinking along those lines too.... As for bathroom accessories, we have everything except tiles, floor tiles, and sauna material....
