Kit Pink Lilac is a 4.5" x 9" porcelain tile. Porcelain is pressed and fired denser than ceramic, which is what lets it take water, frost and daily traffic. A matte face holds light rather than throwing it back, so it hides dust and water spotting between cleans. Porcelain of this density suits floors and walls through the home. Order the area you are covering plus about ten percent for cuts and waste.
