The 216 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. The silky black surface of the sink, along with the soft wavy edges, creates a blissful look that will bring comfort and relaxation to any bathroom. A matching glass waterfall faucet is available to correspond with this sink. The overall dimensions for the 612 are 17" x 17" x 7" 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.
