3 Compartment Commercial Sinks

FDA Food Code requires a 3 compartment sink to have three separate compartments for washing, rinsing, and sanitizing. Each compartment must be large enough to submerge the largest utensil used. The sink must be NSF approved or meet equivalent sanitary standards, with a proper drainage setup. Coved corners and sanitary rolled rims, as featured on Griffin Products NSF-approved models, support compliance with these standards.

16 gauge is standard for most commercial food service kitchens and is suitable for restaurants and institutional settings. 14 gauge is recommended for heavy industrial environments such as meat packaging and high-volume food processing. Griffin Products offers both, with 14 gauge Trinity and Wichita lines featuring bi-directional gusseted leg sockets and up to 10-year warranties for maximum durability.

Yes, in most jurisdictions commercial kitchen sinks are required to be NSF approved or equivalent. NSF certification ensures the sink meets sanitary construction standards for food contact environments, including materials, surface finish, and drainage design. Most Griffin Products 3 compartment sinks carry NSF approval and feature coved compartments, sanitary rolled rims, and recessed drain openings that support code compliance.

Sizing depends on the largest items you need to wash. Bowl dimensions range from 10x14 inches on compact Pecos models up to 24x30 inches on larger Sabine and Trinity models. Health codes generally require bowls large enough to submerge the biggest utensil or equipment piece used. Griffin Products offers extensive size options with bowl depths from 12 to 24 inches to accommodate most commercial kitchen requirements.

Many Griffin Products 3 compartment sinks include integral drainboards in configurations with left, right, or both-side drainboards in lengths from 18 to 24 inches. Drainboard models are clearly designated in the product name (e.g., L24 or R18 indicates a 24-inch left or 18-inch right drainboard). Models without drainboards are also available for kitchens where space is limited.

Coved corner sinks feature 3/4-inch radius rounded interior corners, which eliminate tight angles where bacteria and debris can accumulate, making them NSF approved and ideal for meat processing and high-sanitation environments. Square corner sinks have traditional 90-degree corners and are often preferred for retro styling in standard commercial kitchens. Griffin Products offers both designs across its Sabine, Trinity, Terrell, and Wichita sink lines.
