The PUPSB porcelain undermount 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. Undermounting a bathroom sink creates a sleek look and allows for more space on your countertop. The overall dimensions for the UPS-B are 16 1/2" x 13 1/8" x 7 5/8" and requires an 18" 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.
