The 226 frosted 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 square frosted glass sink has raised edges and a soft look to create a feeling of harmony and relaxation in any bathroom. A matching glass waterfall faucet is available to correspond with this sink. The overall dimensions for the 622 are 18 1/4" x 18 1/4" x 6 1/8" and a 21" 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.
