Mono Onyx Grey is an 8.5" x 9.7" polished porcelain mosaic from Sarana Tile. Visually it offers the broken, tonal face of natural stone. The finish gives it a polished face with a full reflective shine. In a home it suits 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 8.5" x 9.7", listed metrically as 21.7x24.5cm. Each sheet covers roughly 0.45 sq ft. It appears in the Sarana Volume 8 catalogue at page 132. 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.
