The B91 Bamboo Vessel Sink is manufactured using 100% renewable bamboo stalks, which are laminated to create a leak-proof seal. The minimalist design of this square sink has simple lines and warm hues. A corresponding Bamboo 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 B91 vessel sink are 16 1/8" x 16 1/8" x 5 1/8" and an 18" minimum cabinet size is required. As always, our bamboo sinks are covered under a limited lifetime warranty for as long as you own the product.
