Rene R3-2008-Concrete Double Offset Bowl Low Divide Topmount 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. It has a wide-rimmed perimeter, and a ledge along the back with scored faucet and accessory holes. The R3-2008-Concrete is constructed from a unique blend of ground quartz (80%), acrylic (20%). Overall, this topmount sink measures 33 x 22 x 10 1/2. Its deep basins are inherently quiet, stain-resistant, scratch-resistant, and even heat-resistant to temperatures up to 550 degrees. 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 in a matching concrete finish. They not only catch random waste but provide the finishing touch to the sink's appearance.
