Doesn't detract from the fact that whoever tiled it didn't do a good job. If the plumber left capped pipes to tile around then that's fine and in ideal world, just what you want..... The tiler should have checked the room for plumb before doing anything, in this case as the walls are waaaay off plumb he should have let the client know before just going ahead and starting the job...... I mean, that's what is meant by professionalism.To me it looks like !what happens all too often , a plumber has also been involved in the new bathroom , as capped pipes in picture , it's very easy for criticism, but we don't know budgets etc etc !! Is a builder involved , it's not right that walls are wrong , but who was responsible for preparation??
