We have some of these where I work one plasterer and one tiler, push fit heroes. Install bathroom suites in hep2o, some on show, looks unsightly - but the managers love em, coz they just get on with the job and then do the tiling/plastering as well. Saw a bath installed, yes it was tight-ish to the walls, but no clips, with movement, seen wc pans “screwed” down with either screws sticking up, or 2”x8’s used, and another one was a kitchen refurb was done, and they’d installed x2 new washing machine valves, and cut the back out of the unit for the old ones.
