A bar sink used for washing, rinsing, and sanitizing is most commonly called a three-compartment sink or a 3-comp sink. In commercial food service settings it may also be referred to as a warewashing sink or a multi-bay sink. Health codes typically require three separate compartments for wash, rinse, and sanitize steps.
