3 Compartment Dishwashing Sinks

The proper sequence is wash, rinse, sanitize. Start in the first compartment with hot soapy water to remove food particles and grease, move to the second compartment for a clean water rinse to eliminate soap, then finish in the third compartment with approved sanitizing solution or 171°F water. Scrape and pre-rinse dishes before washing for best results.

NSF-approved sinks feature 3/4-inch radius coved corners that eliminate tight angles, making them easier to clean and meeting NSF sanitation standards required for food service. Square corner designs offer robust retro styling with integrated security flanges, ideal for heavy industrial use. Both meet commercial standards, but NSF-approved models are specifically certified for food service compliance.

14GA (heavy-duty) stainless steel is thicker and more durable, recommended for meat packaging, high-volume food processing, and heavy industrial environments. It comes with a 10-year warranty. 16GA (standard commercial) works well for typical restaurant and commercial kitchen applications with a 5-year warranty. Consider your usage intensity and budget when selecting.

Bowl sizes range from 10x14 inches (small, space-saving) to 24x24 inches (extra-large for sheet pans). For restaurants washing pots and pans, 18x24 or 20x24-inch bowls are common. Consider your largest cookware, available space, and volume of dishes. Bowl depths range from 12 to 14 inches—deeper bowls accommodate larger items.

Drainboards provide space for air-drying sanitized dishes and staging dirty items before washing. Single drainboards (left or right, typically 18-24 inches) work for moderate volume operations. Double drainboards offer maximum staging area for high-volume kitchens. No-drainboard models save space in compact kitchens where separate drying racks are used.

Yes, most models include specification-grade wall-mounted faucets with 12-14 inch swing spouts, basket drains, and installation kits. Trinity series (14GA) and Sabine series (16GA) include complete hardware. The number of faucets varies by sink configuration—larger models with double drainboards typically include two faucets for efficient workflow.
