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.

Frequently asked

What is a 3 compartment sink?
A one-compartment sink is a commercial stainless warewashing/prep sink with 1 bowl. A single-compartment sink is for food prep or utility use — it does not meet the manual warewashing requirement (which needs three compartments).
How big is a 3 compartment sink?
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.
3 compartment sink vs dishwasher
A 3-compartment sink is for manual warewashing (wash/rinse/sanitize); a dish machine speeds it up but many health departments still require the 3-comp as a backup and for large items. They are complementary, not either/or.
How much is a 3 compartment sink?
BK 1-compartment sinks run about $604–$2350 list depending on bowl size, drainboards and tier (see the table). Dealers sell below list.
Do I need a 3-compartment sink if I have a dishwasher?
A 3-compartment sink is for manual warewashing (wash/rinse/sanitize); a dish machine speeds it up but many health departments still require the 3-comp as a backup and for large items. They are complementary, not either/or.
How big does each compartment need to be?
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.
