Hi, I currently have a bespoke shower tray that is raised to sit on a cover that runs around 2 walls of my ensuite covering the waste pipe from the sink and shower to the main waste pipe from the loo. The copper supply pipes also come up under the shower and then form an S bend before going behind the wall to the mixer. Is there a reason why these pipes weren't hidden under the floor boards by the original builder? We would like to put a floor level shower tray in, and get rid of the boxing that goes around the current pipes.
Am I missing something, or can I hide these pipes under the floor :?:
