Dolce + Vita Gris is a 12" x 25" ceramic tile with rectified edges, cut square after firing so the grout joint can close to about an eighth of an inch. 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. At this size the grout lines fall further apart, which makes a room look larger. Order the area you are covering plus about ten percent for cuts and waste.
