I'm planning to enclose my bathtub. Partly a 10cm surface on 3 sides that will be tiled on top, and one side with a tiled front that I should be able to dismantle if I want to work on the drain (no surface on this side).
To the question:
Can this be done with simple XPS boards, or do I have to go with the expensive Lux boards (or other reinforced XPS boards)? :wow:
