A 1-compartment sink is often used to prep fruits and vegetables, where running water is necessary to wash produce clean and facilitate processing. A one-compartment prep sink with a garbage disposal can make quick work of getting rid of peels, rinds, and other refuse. Other times, these sinks are used to soak wares that are destined for a wash sink or dishmachine. Single compartment sinks come in many sizes and designs. They're available with or without drainboards on one or both sides.
