The R3-1005-Concrete is constructed from a unique blend of ground quartz (80%), acrylic (20%). Overall, this spacious sink measures 24 3/4 x 22 x 8 1/4 and is 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, one superior-quality, custom-fitted, stainless steel grid is included. Its removable rubber feet raise it slightly above the bottom of the sink. Included is one flange in a matching concrete finish. It fits directly over a garbage disposal, and provides the finishing touch to the sink's appearance.
