Granite composite sinks come in many brands.  Here at Unique we offer Blanco sinks that have consistently met our rigorous standards. Composite sinks as a whole are made with somewhere between 80%-90% granite.  This gives them an incredible resistance to heat, stains, chips and almost anything else that your sink would ever come in contact with. Rest assured we carry only the finest options with all of our products, and our composite sinks are no exception. We wouldn't put anything in your house that we wouldn't be comfortable with in our own.
