Every commercial kitchen needs a sink - and most could use more than one. But with so many different kinds, finding the perfect sink for your business can be a challenge. That's why we've laid out all the factors that you need to consider when searching for a sink of your own. From the number of compartments to the material of the unit and more, all you need to know about compartment sinks can be found right here.

The material of the sink you buy is just as important as its number of compartments and size. All compartment sinks are made of stainless steel to ensure long-lasting durability, but there are different grades of steel used. Type 430 steel is commonly used in the industry for all kinds of equipment, and it ensures you get your money's worth when purchasing a sink. Type 304 is also very dependable with the added bonus of extra rust and corrosion resistance. This makes it better for use in wet environments, like coastal areas, where it will be able to stand up to the constant humidity.

Each compartment sink is also made with a specific gauge of steel. The gauge is a measurement of the steel's thickness, with lower gauges indicating a thicker metal. The thinnest gauge used for sinks is 18 gauge, which is thick enough to ensure a reliable purchase. The toughest sinks are made of 14 gauge steel, which adds durability and increases the weight of the unit. So while an 18 gauge Type 430 steel sink will be strong enough for most kitchens, the heavy duty 14 gauge Type 304 sinks are designed to stand up to more use for a longer time.

For the best convenience, compartment sinks can come with drainboards on one or both sides for a variety of purposes, from drying washed dishware to adding extra table space. Most sinks also include holes drilled into the backsplash to support nozzle, gooseneck, or pre-rinse faucets, depending on what you need, to give you the chance to streamline rinsing and cleaning. With three and four compartment sinks, the units commonly come with multiple centers punched over different sinks so that you can have multiple faucets for separate purposes while you work.
