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 731-ABR , single-handle, vessel faucet reaches a height of 12 1/4" and features a classic trough-style spout with a 4" reach. Its sleek lines gradually widen and contract to create a stunning design statement. The single handle has a flat top with an inverse curve below to mimic the spout design; and it easily sets just the right water flow and temperature. Ceramic disc cartridges assure long-term, dependable operation, and a beautiful 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.
