Health-department & code relevance PREP / UTILITY — NOT WAREWASHING

A single-compartment sink is for food prep or utility use — it does not meet the manual warewashing requirement (which needs three compartments). Note it is also separate from the required dedicated hand sink and mop/service sink.

Which size is right?

Match the bowl to the job — a 10"×14" prep bowl, or a deep utility basin. Remember it does not replace your hand sink or 3-comp warewashing sink.
