4-Compartment Sinks
A 4-compartment sink adds a fourth bay to the standard wash-rinse-sanitize line — most often used as a pre-scrape or pre-soak station ahead of washing, or as a dedicated prep bay. Some local health jurisdictions specifically require four compartments for certain operations, so a 4-bay sink is the safe choice when your plan reviewer calls for it or when high soil volume makes a pre-scrape step worthwhile. The trade-off is footprint: four bowls plus drainboards can run 100″ or more, so confirm the wall run and aisle clearance before ordering. As with any warewashing sink, match the bowl size to your largest pans, favor 304 stainless and 16-gauge for durability in a constantly-wet area, and verify the required compartment count and bowl dimensions locally before you buy.
A 4-compartment sink adds a pre-scrape or prep bay to the wash-rinse-sanitize sequence, and some jurisdictions require it. Compare 4-bay models below. ← All Commercial Compartment Sinks
About this data
Last verified: August 2026. Specs are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn't published we leave it blank rather than guess.
Methodology: every compartment-sink model is compared on the same set of specifications, and dimensions are checked (for sinks, overall width must exceed the combined bowl widths) — figures that fail validation are corrected from the manufacturer model number or omitted. “Street price” is the lowest legitimate published price we've found and can change.
Sourcing: product specs come from the manufacturer; regulatory statements link to the source (e.g. the FDA Food Code and NSF). Code requirements vary by jurisdiction — confirm with the authority reviewing your plans.
