Health-department & code relevance PREP / BAR — NOT FULL WAREWASHING

A two-compartment sink covers prep or bar use; on its own it usually does not satisfy the wash-rinse-sanitize warewashing requirement (that needs three). Some jurisdictions allow a two-comp at a bar paired with a glasswasher — confirm locally.

Which size is right?

Two-compartment sinks fit prep stations and bars. Bowl size follows what you soak/rinse; pair with a dish machine or a separate 3-comp for warewashing.
