Optimize your back-of-house workflow with the EFI SI821-3R triple compartment sink. Crafted from 18-gauge Type 304 stainless steel, this corner-drain model combines durability, hygiene, and efficient drainage—ideal for commercial kitchens, catering operations, and institutional foodservice. Each of the three 18″ × 21″ × 14″ (45.7 × 53.3 × 35.6 cm) bowls features coved corners and die-stamped bottoms to promote positive drainage. The integrated 21″ × 14″ (53.3 × 35.6 cm) right-side drain board simplifies washing and staging, while welded-in gussets and optional leg braces ensure rock-solid stability under heavy loads.

Features:

• 18-Gauge Type 304 Stainless Steel: Corrosion-resistant, easy to sanitize, and built for daily commercial use.

• Triple 18″ × 21″ × 14″ Bowls (45.7 × 53.3 × 35.6 cm): Deep, coved corners and 5/8″ (1.6 cm) radius for safe, thorough cleaning.

• Right-Side Drain Board: 21″ × 14″ (53.3 × 35.6 cm) die-stamped surface with positive slope channels water back into the sink.

• Corner Drain Design: 1 7/8″ (4.8 cm) diameter drain hole with basket, guard, overflow pipe, and extension for reliable wastewater removal.

• Pre-Cut Faucet Holes: 8″ (20.3 cm) center back splash with 1″ (2.5 cm) holes fits standard wall-mount faucets.

• Seamless TIG Welding: Blended satin-finish welds and reinforced gussets maintain strength and a sleek appearance.

• Adjustable Legs: 1 5/8″ (4.1 cm) galvanized steel legs with 1″ (2.5 cm) bullet feet for precise leveling.
