One of the curses of being in the tile industry is being able to spot that one tile in a set that is misaligned or not level. In my 20-year-old main master bath, which someday I’ll get to fixing, I have a tile at eye level with a lippage problem that haunts me every morning — and it’s only 12 x 12 inches!
