The 853 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. The overall dimensions for the 852 are 16 1/2-Inch x 5 1/2-Inch x 5/8-Inch thick and an 18-Inch 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.
