What Is a Scullery Sink?
A scullery sink is a heavy-duty commercial kitchen sink built specifically for washing pots, pans, and large cooking equipment — distinguished from a standard commercial hand sink or prep sink by larger, deeper basins and heavier-gauge stainless steel construction able to withstand the impact and weight of commercial cookware. Most food service health codes require a minimum of a 3-compartment sink (wash, rinse, sanitize) for manual warewashing where a commercial dishwasher isn't used or doesn't handle oversized items.
Basin dimensions must be large enough to fully submerge the facility's largest pots and sheet pans — a common failure point when sizing, since undersized basins force staff to wash items in multiple stages or angle them awkwardly, reducing sanitation effectiveness. NSF certification confirms the sink meets sanitation and food-contact material standards required by most health departments and is generally a non-negotiable requirement for commercial kitchen equipment.

| Spec | What It Means | Why It Matters |
|---|---|---|
| Basin Count | 1, 2, or 3 compartment configurations | Most health codes require 3-compartment (wash/rinse/sanitize) for manual warewashing |
| Basin Dimensions | Length x width x depth per compartment | Must accommodate the facility's largest pots, pans and sheet pans for full submersion |
| Gauge (Steel Thickness) | Typically 14-16 gauge stainless steel | Heavier (lower number) gauge resists denting and withstands impact from heavy commercial cookware |
| NSF Certification | NSF/ANSI Standard 2 compliance | Required by most health departments for commercial food service equipment |
| Drainboards | Left, right, or both sides; integrated or removable | Provide staging space for soiled and clean items, reducing cross-contamination risk during workflow |

FAQ
Scullery Sinks Questions, Answered
How many compartments does my scullery sink need?
Most health department codes require a minimum of a 3-compartment sink for manual warewashing (wash, rinse, and sanitize as separate steps) unless the facility relies entirely on a commercial dishwasher for items that fit it. Check your local health code specifically, since requirements can vary by jurisdiction and facility type.
What basin size do I need for my kitchen's largest pots?
Measure your facility's largest pots, sheet pans, and equipment, and choose basin dimensions that allow full submersion with some clearance — undersized basins force staff into awkward multi-stage washing that reduces both efficiency and sanitation effectiveness. It's generally better to size basins to your largest regularly-washed item than to the average.
Does my scullery sink need to be NSF certified?
Yes, in virtually all commercial food service settings — most health departments require NSF/ANSI Standard 2 certification (or equivalent) for sinks and equipment in commercial kitchens, confirming the materials and construction meet food-contact sanitation standards. Verify certification before purchasing, since non-certified sinks may fail a health inspection regardless of build quality.
What steel gauge should I choose for a scullery sink?
Commercial scullery sinks are typically 14 to 16 gauge stainless steel, with lower gauge numbers indicating thicker, more dent- and impact-resistant material. Given the weight and impact of commercial cookware being washed daily, err toward heavier gauge (14 or 16) rather than lighter-duty stainless used in prep sinks, which won't hold up as well to scullery use.
Do I need drainboards on my scullery sink?
Drainboards provide staging space on either side of the basins for soiled items waiting to be washed and clean items air-drying, which meaningfully improves workflow and helps prevent cross-contamination between dirty and clean items. They add to the sink's overall footprint, so factor available kitchen space into the decision, but most commercial kitchens with adequate space include them.
