A 3-compartment sink is required by most health codes for manual warewashing, and choosing the right size and configuration keeps your dish station compliant and efficient.
What to Check Before You Buy
Compartment size, drainboard length, and garbage disposal compatibility are the main factors that determine whether a sink fits your dish volume and space.
- Confirm compartment size fits your largest pots and pans
- Check drainboard length on both sides for wash-rinse-sanitize flow
- Verify local health code requirements for compartment count and size
- Consider garbage disposal compatibility for food waste
- Measure faucet reach and placement for efficient washing
Sizing Your Sink Correctly
Undersized compartments are one of the most common warewashing bottlenecks, forcing staff to wash oversized pots in multiple passes.
| Compartment Size | Best For | Key Feature |
|---|---|---|
| 18″ x 18″ | Smaller kitchens, standard cookware | Compact footprint |
| 24″ x 24″ | Full-service restaurants | Fits large stockpots and sheet pans |
| With disposal unit | High food-waste volume | Reduces manual scraping and trash handling |
