Yeah I did the whole lot. Building work, Shower install, plumbing for shower, sink etc, plumbing for and fitting of towel rail, fitting of sanitary ware etc etc.
Oh, yes and I also fitted the wet room former :smash:
The only thing I didn't do was the 112mm soil waste for the toilet. That was the other builder's scope.
I'm not as accomplished at tiling as some of you, but I can do a whole bathroom without calling in other trades, which is useful.
