Review: GORGEOUS SINK UNLIKE ANY OTHERS WE HAVE EVER HAD - Gorgeous sink that is the focal point of our kitchen island. We were reluctant to go from what we have always known as the standard stainless double basin kitchen sink to a black granite composite single basin sink but are so very pleased with how amazingly beautiful it looks with the contrasting granite countertops color we chose 'bianco antico'. We also purchased the VIGO VG02001MB Matte Black Pull-Down Spray Kitchen Faucet and all we can say is WOW. What a fantastic combination. The sink is huge compared to a double basin and is solid and well made. Kraus makes a great product that is far less expensive than its competitors. Review: Great product - Looks great!
