Used in the bathroom for a wall and window sill. They are easy to fit and work with and look really nice but there’s one big problem. Because the tiles are about 2mm thick and the individual squares have irregular height at the edges it’s very difficult to grout to sufficient depth to stop want getting under the tiles and lifting them. Mine have only been down a few weeks and they’re lifting already despite being careful to clear up any water that has spilled on them immediately. Adding extra grout isn’t an option as they’re so thin so I’ll have to come up with a plan b. The tiles on vertical walls are holding better for now. So overall really nice, but very limited in where you can fit them.
