This 1/2" thick, tempered-glass vessel is a circular basin constructed of crystal clear glass with a flat bottom and straight vertical sides. 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 4 1/2", it will require a minimum-width cabinet of 18". The 721-ABR , 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 antique bronze 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. Additionally, a spring-loaded, vessel pop-up drain (vpud) is included, which opens and closes with a simple press to its attractive antique bronze cap.
