1 and ½ Basin Single Drainboard RHS Stainless Steel Kitchen Sink (40″ x 20″ x 7″)
Stainless Steel 1.5 Basin Sink – Efficient Right Hand Drainboard for Maximum Utility in 40″ Design
This Stainless Steel 1.5 Basin RHS Drainboard Kitchen Sink is a highly functional and durable fixture designed for multi-tasking kitchens. Emphasizing utility, the sink features a 1.5 bowl configuration—one large main bowl for washing and a smaller half bowl for rinsing, food prep, or utility tasks. The prominent Right Hand Side (RHS) Drainboard is integrated directly into the deck, providing a dedicated, sloped area for air drying dishes, draining produce, or holding prep materials while ensuring the countertop remains dry.
Constructed from durable, corrosion-resistant Stainless Steel with a deep 7-inch depth, this sink offers excellent longevity and high capacity. Its 40″ x 20″ overall dimensions and standard drop-in (top-mount) configuration make it a practical and versatile choice for remodels and new installations.
