This sink features a thick 16-Gauge T-304 grade stainless steel construction that is resistant to rust and tarnishing. Its matte black gunmetal finish is achieved through an innovative nano-PVD technique that provides a durable and peel-resistant outer layer. Additionally, the matte texture not only adds to the aesthetic appeal, but also resists fingerprints and stains. The sink also boasts a heavy duty sound proof coating and thick rubber padding to reduce noise and condensation. Measuring at 33 in. W by 22 in. (front-to-back), with an interior bowl size of 31 in. W x 18 in. (front-to-back) x 9 in. (bowl-depth), this sink can fit into a minimum base cabinet size of 36 in. Its standard 3.5 in. drain opening is compatible with any garbage disposal unit (note: matching garbage disposal flange [model # RVA1041BL] sold separately).
