Abitare Nordic Smoke is a 12" x 23.6" Porcelain Tile. Porcelain is pressed and fired denser than ceramic, which is what lets it take water, frost and daily traffic. Porcelain of this density is normally specified for floors and walls through the home. A box covers 15.5 square feet, so order the area plus about ten percent for cuts and waste. Supplied by Sarana Tile.
