The Handmade Series PL-HA109 Kitchen Sink is formed using premium 18 or 16 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 modern sink is entirely handcrafted and boasts zero or fifteen degree corner radiuses, straight walls, and an extra deep bowl. The elegant satin brushed finish keeps its 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 conceal sounds and prevents condensation from forming underneath. The Handmade Series Sinks come with a Limited Lifetime Warranty.
