The Q24M D-Bowl sink is made from a granite composite material that is comprised of 80% Quartz and 20% Acrylic. The non-porous finish of our Quartz sinks gives it anti-bacterial properties. Aside from being anti-bacterial, the Q24M is stain and scratch resistant and can resist heat up to 550 degrees. The overall dimensions of the sink are 24 3/4" x 22" x 8 1/4" and a 27" minimum cabinet size is required. The sink contains a 3 1/2" offset drain and is available in multiple colors. As always, our Quartz sinks are covered under a limited lifetime warranty for as long as you own the sink.
