The M85WD wood sandstone vessel sink is made from natural sandstone. The sink is carved from a large block of sandstone and smoothed out to create a beautiful sink. This sink has a wood-looking pattern with weaving colors of brown and tan. Since sandstone is a natural stone, the details will vary in color and pattern from sink to sink. The overall dimensions for the M85WD 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.
