Hi everyone. I'm taking the bath out and replacing it with a shower enclosure. This involves building a stud wall to hide shower pipework. Using a low profile shower tray, but not sure whether to place it directly on the wooden floor or with a riser kit. On th floor pipes etc wouldn't be readily accessible as would be along / under floor joists and a new Outlet through the wall. I read conflicting rules. To alter a bathroom into a shower room and alter drainage pipes and shower pipes, do I need to get building regs approval?
