The P358 honey onyx vessel sink is made from natural onyx. The sink is carved from a large block of onyx, a type of marble, and smoothed out to create a beautiful sink. This sink has an all-over yellow color with light tan and red veins running through it. Since onyx 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 P358 are 16 1/2" x 16 1/2" x 5 1/2" and an 18" 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.
