Sk Cronos Blanco is a 9" x 13" porcelain tile from Sarana Tile. On the residential side that covers kitchens, entry foyers and open-plan living areas. It also carries commercial use in retail floors, restaurant dining rooms and hotel lobbies. The nominal size is 9" x 13", listed metrically as 22.5x32.5cm. Sarana catalogues it in Volume 8 on page 163. Porcelain is pressed and fired dense enough to take water and traffic that a wall-grade ceramic could not.
