Atlas Grey is a 3" x 12" Ceramic Tile. Ceramic fires lighter than porcelain and cuts more cleanly, which is what makes it practical on walls. It is suited to walls and light-traffic areas. The plank shape can run in a straight lay or a herringbone to draw the eye down a room. A box covers 10.76 square feet, so order the area plus about ten percent for cuts and waste. Supplied by Sarana Tile.
