Sarana Tile lists Oset Hexagon Neo White as an 8" x 9" porcelain tile. Residentially it works in 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 8" x 9", listed metrically as 20x23cm. It appears in the Sarana Volume 8 catalogue at page 147. Sarana prices it by the square foot. Porcelain is pressed and fired dense enough to take water and traffic that a wall-grade ceramic could not.
