Hi, i need to put in a shower tray on a concrete floor in a ground floor room. I was looking at a floor level tray (essentially a wet room scenario) however looking at other threads it seems that you need to be able to access the plumbing for maintenance. How would this work if you install a wet room, as there is essentially no access to the underside of the tray? Also, can you get full length folding shower screens? I can only seem to find folding screens for bath/showers. The reason i need a folding screen is because above the shower is access to a loft area, and if i put in a normal shower screen that will essentially block it off. Therefore i need a screen that can be moved to the side when required.
