Types of Compartment Sinks

by Lawton Brothers | Oct 28, 2021

Commercial kitchens can benefit greatly from the efficiency and utility of a compartment sink. With multiple types available, however, it’s important to factor in every detail to determine the best sink for your space. 

Number of Compartments

The most important factor when considering a compartment sink is how many compartments you’ll actually need. While the common number of compartments is three, you can also opt for a single, two, or four compartment sink. By increasing the number of compartments, you can increase efficiency and workload across your facility.

One Compartment: The most simple option, the single compartment is best for saving space. Ideally used for utility or vegetable washing, this style is perfect for food trucks and small spaces.

Two Compartments: With an additional compartment, this style can be adapted with various sizes and depths for your compartments. These sinks are best for thawing and prep work and are ideal for cafes, stands, and small bars. 

Three Compartments: These are the most common compartment sink. Typically used to isolate different steps in the cleaning process, the compartments can be used to wash, rinse, and sanitize dishes. This is the ideal sink for most restaurant kitchens. 

Four Compartments: With four separate compartments, these sinks take up quite a bit of space. The additional compartment is generally used as an extra step (to scrape dishes) before washing. These sinks are generally only used in universities, hospitals, and other large-scale settings. 


Generally speaking, all compartment sinks are made of stainless steel. However, not all stainless steel was created equally! Most sinks will either be 304 stainless steel or 430 stainless steel. The difference is a small percentage of nickel that is present in 304, helping it to better resist corrosion. While 304 is not magnetic, it is typically preferred thanks to its extra rust-resistance, especially in wet environments. 


The gauge of steel indicates its thickness, with lower gauges indicating a thicker metal. While this does not change the overall use of your sink, it will affect its strength and durability. The thinnest stainless steel used (18 gauge) is best suited for soft water areas, where it will not be corroded daily by chemicals from hard water. Next up is 16 gauge; this ‘medium’ grade provides stronger support, particularly in the legs and basins. As expected, the most durable (and thickest) gauge is 14. For long-term, daily use, 14 gauge stainless steel will hold the test of time.
