Onyx Lux Dark Grey is a 12" x 12" polished porcelain mosaic from Sarana Tile. The surface carries the broken, tonal face of natural stone. It is finished with a polished face with a full reflective shine. In a home it suits kitchens, entry foyers and open-plan living areas. Commercially it is specified for retail floors, restaurant dining rooms and hotel lobbies. The nominal size is 12" x 12", listed metrically as 30x30cm. Sarana catalogues it in Volume 8 on page 145. It arrives mesh-mounted, so the spacing holds while the sheet is set and it trims down to meet a corner or a niche. Sarana prices it by the sheet.
