Hello.
I have a small puzzle in the bathroom window.
I need to cover around the window with something. In the rest of the bathroom, there will be 15mm k-ply, - drywall - waterproofing - tiles. But in the niche around the window, all these layers become too thick.
I found a board at Byggmax "trossbottenskiva" in fiber cement, can't one of these replace both k-ply and drywall just in the niche? Then tiles on top? https://www.byggmax.se/trossbottenskiva-fibercement-p07043
