John Boos UBS4-2184-2D18 Underbar 4-Compartment Sink – 84"

Engineered for the fast-paced bar or beverage station, this 84" John Boos underbar sink delivers four dedicated wash bays, generous left & right drainboards, and the rock-solid durability operators expect from America’s premier stainless-steel fabricator.

Why It Belongs Behind Your Bar

• Four 10" W × 14" F-B × 10" D fabricated bowls keep washing, rinsing, sanitising & dumping completely separate.
• Two 18" creased drainboards (left & right) speed drying and include removable perforated inserts for easy cleaning & improved air circulation.
• 3" integrated backsplash with two removable faucet plates pre-punched on 4" centres—mount faucets now or later without pulling the sink off the wall.
• Heavy-duty 18 GA, Type 300 stainless steel throughout with #4 satin finish resists corrosion and wipes clean fast.
• Bolt-on 1 5⁄8" round stainless legs with side-to-side & front-to-back bracing add rigidity; 1" adjustable bullet feet level the unit on uneven floors.
• Factory-installed 1-1/2" drains, basket strainers & overflow stand pipes (model PB-OVF-BS) are included—no extra kit to buy.
• NSF certified for open-food contact and beverage service.
• Side panels arrive pre-drilled, allowing multiple underbar sections to bolt together for a seamless line-up.
