Home Depot

Those are made by a Spanish company called Aparici, but I believe you can order them here: http://www.specialtytile.com/tile/vanguard

There is another way for fake cement tile : The tile wall decals in wallsweethome.fr imitating the real cement tiles.

The BW tile is from SOCI. It's a cement tile. If you are interested, you can order through our showroom. It's beautiful!
