Rene R3-1008-Concrete Double Offset Bowl Low Divide Undermount Composite Granite Sink. Two Grids, and Two Matching Colored Strainers - Overall Size: 33 x 22 x 10.5 - A concrete-colored, composite sink with two offset basins each with slightly bowed backsides and a low divide between them. The R3-1008-Concrete is constructed from a unique blend of ground quartz (80%) and acrylic (20%). Overall, this undermount sink measures 33 in. x 22 in. x 10-1/2 in. Its deep basins are inherently quiet, stain-resistant, scratch-resistant and even heat-resistant to temperatures up to 550ª. The smooth non-porous surface gives the sink anti-bacterial properties, leaving nowhere for bacteria to thrive. It is guaranteed by a limited lifetime warranty, with template and mounting hardware included. To protect the sink surface from scratches or dents, two superior-quality, custom-fitted, stainless steel grids are included. The removable rubber feet raise them slightly above the bottom of the sink. Included are two strainers to catch random waste; both in a matching concrete finish.
