Novatto's travertine onyx vessels are sure to add a touch of charm to your bath. Each irregular vessel is beautifully unique. Since these sinks are from Mother Nature, each sink will vary slightly in color, shape, and size. We will send pictures of the one we intend to send for approval. These sinks are constructed for above-counter installation. Included is an umbrella drain in your choice of finish: brushed nickel, chrome, matte black, or oil-rubbed bronze. Supreme packaging and boxing ensure damage-free delivery. Enjoy Novatto's limited lifetime warranty!
