Prep Sink

A prep sink is a small secondary sink in the kitchen, typically 15-20 inches wide, dedicated to food preparation tasks like washing vegetables, rinsing herbs, or filling pots. By reserving this sink exclusively for prep work, the main sink remains available for cleanup, dishes, and other tasks—particularly valuable when multiple cooks work simultaneously. Prep sinks are common features in high-end kitchens. They're typically installed in kitchen islands or peninsula areas, creating a dedicated prep zone separate from the main cleanup sink.
