The Quartz Granite T824-Beige D-bowl, topmount sink is made from a granite composite material comprised of 80% Quartz and 20% Acrylic. The non-porous finish of our Quartz Granite sinks gives it anti-bacterial properties. Besides this anti-bacterial quality, the T824-Beige is stain, scratch, and heat-resistant up to 550 degrees. The overall dimensions of the sink are 25" x 22" x 8 1/4" and a 27" minimum cabinet size is required. Its 3 1/2" drain is offset. As always, our Quartz Granite sinks are covered under a limited lifetime warranty for as long as you own the sink.
