John Boos 3 Compartment Underbar Sink 72" Two 18" Drainboards
The John Boos UBS3-1872-2D18-X is a 72-inch, NSF-certified underbar 3 compartment sink built for the wash-rinse-sanitize setup bars and beverage stations need to stay code-compliant. At 18 inches deep and 32-1/2 inches tall, it fits under a standard bar counter and leaves room to work. Bar managers, contractors, and foodservice equipment buyers use this unit where space is tight but a full three-compartment run is required.
- Three compartments, each 10" W × 14" front-to-back × 10" deep — sized right for glassware, bar tools, and small wares
- 18-inch drainboard on both left and right sides, each with a removable perforated insert for draining and staging
- 18-gauge, Type 300-series stainless steel construction throughout
- NSF certified — meets health department requirements for regulated commercial foodservice and bar environments
- Includes 1-1/2" drains and overflow standpipes; 4-inch on-center faucet holes on the splash mount
- Stainless steel legs with side bracing and adjustable bullet feet; removable back or front-and-back legs allow for a built-in counter installation
This is a working sink for a real bar build-out — underbar depth, dual drainboards, and the NSF stamp inspectors expect. Sold as a single unit.
