Commercial Underbar Dump Sinks

A waste sink, often called a dump sink, is a small stainless steel basin used in bars and concession stands to discard liquid waste such as melted ice, drink remnants, and rinse water. It's typically part of an underbar compartment sink layout and connects to a drain line for quick, sanitary disposal during high-volume service.

For compact underbar layouts, Griffin's Pecos series small-bowl models (10 x 14 inches or 15 x 15 inches) are popular choices. These compact configurations fit efficiently into limited bar counter space while still providing enough basin depth for ice disposal and glass rinsing during busy service periods.

Yes, Griffin Products' compartment and dump sinks are NSF approved, meaning they meet recognized food service sanitation standards. This certification confirms the stainless steel construction, seams, and drainage design support safe, sanitary operation in commercial bar and food service settings.

Griffin offers 14-gauge and 16-gauge stainless steel options. 14GA is thicker and more resistant to dents and heavy daily use, making it ideal for high-volume bars, while 16GA offers a more economical option that still meets standard commercial durability requirements for moderate-traffic operations.

Yes, Griffin's compartment sink configurations support optional 12, 18, or 24-inch drainboards on standard 1, 2, and 3 compartment models. Four-compartment layouts and other custom configurations can be built as special orders to match specific underbar or concession layout requirements.

Griffin Products includes specification-grade hardware with its sinks, such as faucets, drains, and installation kits, so operators receive a complete, ready-to-install unit rather than sourcing components separately, streamlining setup for bar and concession installations.
