The 736 Foil Undertone Glass Vessel Sink is manufactured using fully tempered glass, which is non-porous, easy to clean and resistant to stains and odors. This vessel sink has a dark bronze foil underlay which creates a unique pattern throughout the bowl. A corresponding Glass Waterfall Faucet is available with this sink, which includes a matching disc and your choice of chrome, brushed nickel or oil rubbed bronze faucet. The overall dimensions for the 637 are 16 1/2" x 16 1/2" x 5 3/4" thick and an 18" minimum cabinet size is required. As always, our glass sinks are covered under a limited lifetime warranty for as long as you own the product.
