PVC as a tile substitute on the wall in bathroom and kitchen

Dear forum,

I am currently creating an apartment in the attic and have installed partition walls for the bathroom and kitchen using timber frame construction. In the living area, the OSB-clad walls will be covered with drywall and painted.

In the bathroom and kitchen (only the kitchen backsplash) I would like to try something modern and seamless and came across the following video of a tiler who simply sticks PVC flooring to the wall.

I like the look very much and it is easy to produce. I want to stick it directly onto the OSB boards. Should I treat them beforehand with a primer (if yes, which one) for water protection and/or tack a vapor barrier foil before bonding?

The entire apartment/bathroom will be heated with underfloor heating supplied by a heat pump and has a relatively low flow temperature. Accordingly, suitable laminate will be used as the floor covering.

In the wet area, i.e. the bathroom and in front of the kitchen unit, I would like to either use tiles or, here too, go for a seamless option, namely vinyl. Is there anything against using vinyl in connection with underfloor heating, or should I rather use tiles in the bathroom due to the better heat transfer?

Many thanks

Michael

Vinyl and FHZ work well. In my opinion, you can stick directly onto OSB board.

Thank you very much and what about the topic of wall cladding (so PVC / vinyl etc. is basically the same raw material)? The idea with the stapled vapor barrier film is probably not so good. I fear that the covering will not hold then. Should I prime the OSB boards and if so, with what?

Thank you very much

Michael
