i am thinking about fitting a shower tray on a concrete ground floor, the last one i did, i put channels into the concrete for the waste pipe and trap, so the shower tray was flush with the floor, there is no way to access any traps or pipe work once it was fitted!!, is this a normal way of doing it or iam i much better off using a riser system for the tray?? i dont have a lot of head room to play with though.
its at a rough building stage so cutting the concrete is not too much of an issue.
any thoughts?
thanks carl
