Composite granite sinks require careful installation. The knockout holes on topmount sinks must be carefully hammered or the sink will crack. Undermount sinks must be supported properly with bolts and epoxy to prevent them from collapse through the cabinet sink hole.

Composite granite sinks are very hard and less forgiving on brittle dishware than the more ductile stainless steel sinks. These sinks are usually more expensive than other sinks, some costing $1,000 or more.
