Three-Compartment Underbar Sink Requirements: A Guide
Three-compartment sinks are a standard health code requirement behind most bars, used for washing, rinsing, and sanitizing glassware without relying on a dishwasher for every glass. Understanding sizing and layout requirements helps plan an underbar setup that passes inspection and supports fast service.
Why Three Compartments Are Required
Most health codes require separate wash, rinse, and sanitize compartments to properly clean glassware and bar tools without cross-contaminating steps in the process.
Compartment Sizing Requirements
Each compartment needs to be large enough to fully submerge the largest items regularly washed, typically pint glasses or bar tools, per local code specifications.
- Confirm minimum compartment size with local health code
- Include a separate hand sink outside the three-compartment unit
- Plan drain board space on both sides for dirty and clean items
Drain Board Space
Adequate drain board space on both the dirty and clean sides of the sink keeps the washing workflow organized and prevents bottlenecks during busy service.
Separate Hand Sink Requirement
Most jurisdictions require a separate hand-washing sink distinct from the three-compartment sink, an important detail often overlooked in underbar planning.
Integration With Underbar Layout
Positioning the three-compartment sink within the broader underbar layout should balance code compliance with keeping the wash station out of the primary drink-making flow.
Three-Compartment Sink Planning Checklist
| Requirement | Consideration |
|---|---|
| Compartment size | Must fit largest regularly washed items |
| Hand sink | Separate unit required in most jurisdictions |
| Drain boards | Space on both dirty and clean sides |
Frequently Asked Questions
Is a three-compartment sink always required for a bar?
Requirements vary by jurisdiction, but most health codes require a three-compartment sink for manual glassware washing unless a certified dishwasher handles all washing.
Can a bar use a two-compartment sink instead?
Some jurisdictions allow alternatives under specific conditions, but three compartments (wash, rinse, sanitize) is the standard requirement in most areas.
Does a dishwasher eliminate the need for a three-compartment sink?
Not always — many codes still require a three-compartment sink for items too large for the dishwasher or as a backup during equipment downtime.
How is compartment size typically regulated?
Local health codes typically specify minimum compartment dimensions sufficient to fully submerge standard glassware and bar tools.
