I’m quite annoyed. We have re-done our whole bathroom and en-suite, completely new with new tiles (tiled all around), new bathroom fixtures, everything new. We managed this with neither the plumber or the tiler making any marks whatsoever in either the tiles or the fixtures. Then we called a carpenter to make a small bath-side panel to be tiled on and he managed a tiny crack on 2 tiles, plus a long-ish (3 inches) crack on the side of the bath. The crack is not huge but it’s quite visible. Am I right to be annoyed or am I over-reacting?
