Zellige Deep Blue is a 2" x 16" ceramic tile. The pattern carries a room on its own, which is why it is usually run on one wall rather than all four. Ceramic fires lighter than porcelain and cuts more cleanly, which is what makes it practical on walls. It is a wall tile, which puts it on backsplashes, shower surrounds and feature walls. The plank shape can run in a straight lay or a herringbone to draw the eye down a room. Order the area you are covering plus about ten percent for cuts and waste.
