Ek Calacatta is a 3" x 12" matte porcelain tile from Sarana Tile. The face reads as the veining and depth of quarried marble. It is finished with a matte face that holds light rather than throwing it back. On the residential side that covers 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 3" x 12", listed metrically as 7.6x30cm. It appears in the Sarana Volume 8 catalogue at page 71. Sarana prices it by the square foot.
