This marine-grade sink from series is designed for boat decks, or outdoor BBQ grill areas, where extreme corrosion resistance is important. This sink is constructed of Marine-grade T-316 Stainless Steel, which is extremely resistant to corrosion and rusting in saltwater environments or when exposed to outdoor elements. The sink comes with built-in accessories (colander and cutting board) that fit nicely on top of the sink, so you can do your prep work right on top of the sink. The thick cutting board is constructed of food-grade polymer (HDPE) that is resistant to water, UV, and the elements. It covers the entire sink bowl, thus converting your sink into a countertop when you need it. Also included is a 5-inch deep stainless steel colander that you can use as a strainer or a drying caddy. The sink features a 1/4-inch high rim all around that sits on your countertop. The inside of the sink and the rim are finished in commercial-grade brushed finish which adds to the beauty of the sink.
