This 1/2″ thick, tempered-glass vessel is square with triangular sides of clear, tiered glass. Its textured exterior and smooth interior produce a translucent arctic appeal. Its non-porous surface is extremely attractive and sanitary – naturally resistant to stains, odors, discoloration, and heat damage. With an overall measurement of 16 1/2″ x 16 1/2″ x 6″, it will require a minimum-width cabinet of 18″. The 721-BN , single-handle, vessel faucet offers tall, orderly, contemporary styling. Standing at a 12 1/4″ height with a 4 1/2″ spout reach, its distinct edges and geometric angles flaunt a European air. The lone handle atop the 90-degree faucet enhances the fixture’s forthright appearance and ceramic disc cartridges assure long-term dependable operation. An attractive brushed nickel finish completes its distinctive appearance. The faucet is constructed without lead and is compliant with NSF (National Sanitation Foundation) standards, the Safe Drinking Water Act, the cUPC (Uniform Plumbing Code of the United States and Canada), the ADA (American Disabilities Act) and carries the EPAs WaterSense label. The included sink ring stabilizes the curved bowl above the counter and coordinates with the brushed nickel finish of the other fixture’s. Additionally, a spring-loaded, vessel pop-up drain (vpud) is included, which opens and closes with a simple press to its attractive brushed nickel cap.
