Granite composite sinks are molded from crushed stone and resin, which gives them a tough, matte surface that resists scratches and stains. They come in dark and light colors and suit modern kitchens that want a sturdy, quiet sink.
The six sinks below include undermount and drop-in styles from well-known sink makers. We have not used these products ourselves, so please confirm cutout sizes, bowl layout and mounting type on the current listing before buying, since fit matters a great deal. Measure the base cabinet and the countertop opening, and compare faucet hole needs before ordering.
