The P5181OB porcelain vessel/overmount sink is made from true vitreous China which is triple glazed and triple fired to ensure your sink is durable and strong. Our bisque color is a beige hue that contains a yellow tint. An overmounted vanity sink is traditionally found in most bathrooms and can be used with any type of countertops. This sink can also be installed as a vessel. The overall dimensions for the O1815-bisque are 19 7/8" x 16 3/8" x 7 5/8" and requires a 21" minimum cabinet size. Pop-up drains in a variety of finishes are available with this sink model. As always, our porcelain sinks are covered under a limited lifetime warranty for as long as you own the sink.
