The M60HB honed basalt black granite vessel sink is made from natural granite. The sink is carved from a large block of granite and hand-polished for a smooth, easy to clean finish. It is a uniquely shaped black granite vessel with a honed, or matte, finish. Since granite is a natural stone, the details will vary in color and pattern from sink to sink. A matching stone waterfall faucet is available to correspond with this sink. The overall dimensions for the M60HB are 18 1/2" x 14 3/4" x 5" and a 21" minimum cabinet size is required. As always, our stone sinks are covered under a limited lifetime warranty for as long as you own the sink.
