The S208BE equal double bowl undermount sink is made from a granite composite material that is comprised of 80% Quartz and 20% Acrylic. The non-porous finish of our Composite Granite sinks gives it anti-bacterial properties. Aside from being anti-bacterial, the S208BE is stain and scratch resistant and can resist heat up to 550 degrees. The overall dimensions of the sink are 32 1/2" x 18 5/8" x 9 1/2" and a 33" minimum cabinet size is required. The sink contains a 3 1/2" offset drain and is available in multiple colors. As always, our Composite Granite sinks are covered under a limited lifetime warranty for as long as you own the sink.
