Sarana Tile lists Ek Calacatta as a 12" x 12" matte porcelain tile. The surface carries the veining and depth of quarried marble. The finish gives it a matte face that holds light rather than throwing it back. In a home it suits kitchens, entry foyers and open-plan living areas. On commercial jobs it turns up in retail floors, restaurant dining rooms and hotel lobbies. The nominal size is 12" x 12", listed metrically as 30.2x30.2cm. It appears in the Sarana Volume 8 catalogue at page 71. Sarana prices it by the piece.
