The Pelican PL-VR1816 Urban Series Sink is manufactured using heavy-duty 18-gauge 304 Series stainless steel. 304 Series is a surgical-grade stainless steel, meaning it is nonporous, rust-free, and extremely durable. Nonporous sinks are antibacterial and easy to clean as there are no pores for the dirt and germs to get trapped in. Our 304 Stainless Steel has a chromium to nickel ratio of 18:10, making this sink one of the best available for residential and commercial installations. This sink features low-radius corners, giving your kitchen a sleek, modern look. The elegant satin-brushed finish creates an enduring luster and is designed to conceal small scratches that occur during normal usage. The underside of the sink has our special Pelican Protect Coating applied as well as sound deadening pads. This helps prevent condensation from forming underneath and deadens sounds created while using the sink. The Pelican Urban Series Sinks come with a Limited Lifetime Warranty.
