Installing studs on a concrete floor with underfloor heating

[mossanbo]

Hi!

I'm going to build interior walls for a bathroom and bedroom on a concrete floor with underfloor heating.
I don't want to drill into the floor. Hoping for some tips here, I could google but maybe there's someone here who has done this.
1. How do I best attach to the floor?
2. Should I use sill sealer if I'm gluing?
3. Which is better to have on the bathroom wall, OSB or plywood? There will be tile.
4. Can I tile directly on plywood/OSB?
Grateful for tips!

It might be called OSB

walls for bathrooms should have at least 45x70 studs and 15mm plywood and a drywall. Gluing the sill with a mounting adhesive should work fine for an interior wall; sill paper indoors is not needed. Read up on Säker Vatten

Thanks for the response, but can I place the wooden stud directly on the concrete floor?

yes, you can, if you have so much moisture in the slab that the studs would begin to mold/rot, something has gone very wrong. especially since you have heating in the slab, I assume that there is cellplast underneath and it is capillary-breaking.

Okay, whether there is cellplast or not, I don't know, but I'll have to find out. Thanks for the help.

but regardless, if we are talking about a villa foundation where you do not have insulation above the concrete (elevated floor), then just go for it.
