Tile is almost done in the master bath. Eric has been using the Raimondi 'clips' (from Italy) to keep everything in place and tile lippage to a minimum. I have some bright accent lighting in the shower, and I don't want to accent bad tile work! According to everything I read about tile install, the bigger the tile, the more difficult it is to prevent lippage. I think only the most skilled tile setters can avoid it without special tools.
