Sarana Tile lists Salt Stone Desert as a 12" x 13.4" porcelain mosaic. Visually it offers the broken, tonal face of natural stone. On the residential side that covers 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 13.4", listed metrically as 30x34cm. Each sheet covers roughly 1.10 sq ft. It appears in the Sarana Volume 8 catalogue at page 161. 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.
