Hello, In my developer-finish apartment, the water supply and drainage pipes in the bathroom run on the outside of the wall. Chasing them into the wall is not permitted. On the wall, from left to right, I want to install a shower enclosure, a sink and a washing machine with a tumble dryer on top of it. I was thinking of boxing everything in using Botament construction boards. What profiles/system should I use to attach them? How should the water pipes on the back side of the board be attached? Should the space between the board and the wall be filled with anything? The wall is made of aerated concrete. A further question about the radiator: can it be replaced with a smaller one? I'm worried that if it ends up behind the tumble dryer, it may affect the dryer's performance.
