The Amerisink Bar undermount sink is made from a granite composite material that is comprised of 80% Quartz and 20% Acrylic. The non-porous finish of our  sinks gives it anti-bacterial properties. Aside from being anti-bacterial, the black color is stain and scratch resistant and can resist heat up to 550 degrees. The overall dimensions of the sink are 17 3/4" x 16 7/8" x 7 3/4" and an 18" minimum cabinet size is required. The sink contains a 3 1/2" offset drain. As always, our  sinks are covered under a limited lifetime warranty for as long as you own the sink.
