A waterfall kitchen sink is a type of sink that features a built-in channel or trough along the front edge of the sink that allows water to flow smoothly into the basin. The water flows over the lip of the sink, creating a "waterfall" effect.
This type of sink is often made of stainless steel or other durable materials and can come in a variety of sizes and shapes. The waterfall design can add a modern and sleek look to a kitchen and can also be practical as it can help prevent splashing and make it easier to rinse and wash dishes.
