Number of Sink Compartments

The first factor to consider as you look into buying kitchen sinks is how many sink compartments you'll need. Among the types of sinks available, the different number of compartments serve various purposes and help improve efficiency in your establishment. Although the three compartment sink is one of the most common sink layouts in the industry, you can also choose between one compartment, two compartment, and four compartment sinks.

All compartment sinks are made of stainless steel to ensure long-lasting durability, but there are different grades of steel used. You will often find compartment sinks made of either 430 stainless steel or 304 stainless steel.

  • Drainboards: 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.
  • Faucets: 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.
Once you have your compartment sink installed and in use, it is important to clean the stainless steel properly, regardless of the type of sink you own, to ensure that your sink will last for years to come.
