I have a new bathroom; the floor is concrete the walls are villaboard on stud work. The ceiling is Aquachek plasterboard. The walls and floor will be tiled. There will be a wash basin, toilet and shower. The shower is going in one corner, a resin tray with its built-in screen. As I understand it the walls around the shower from floor to a minimum of 1.8m height around the walls of the shower need to be waterproofed.
Is there any other area in the bathroom that should be waterproofed?
Many thanks😊
