The 621 stained glass vessel sink is manufactured using fully tempered glass. This allows for higher temperatures to come in contact with your sink without any damage. Glass is more sanitary than other materials because it is non-porous, will not absorb stains or odors and is easy to clean. This classic bowl-shaped vessel has been painted with warm colors to create a stained glass look over the entire sink. A matching glass waterfall faucet is available to correspond with this sink. The overall dimensions for the 621 are 16 1/2" x 16 1/2" x 5 3/4" 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 sink.
