At first glance, Thassos looks similar to other marble-look tiles, but take a closer look and you will see the subtle slate blue veining that gives it a unique look. Thassos comes in several sizes ranging from an extra large 13x26 porcelain tile to a 4x13 tile that can be used to create a sophisticated brick look. And don't forget about the matching 2x2 mosaic and bullnoses in both matte and glossy finishes. Made in Spain.
