The purpose of kitchen sink liners is to protect ceramic, granite and stainless sinks from spills, scrapes and scuffs. Additionally, these liners protect china, glassware and dishes from chipping while in the sink.
Kitchen sink liners are designed to sit at the base of the sink and conform to its shape, providing a protective barrier between the sink and kitchenware. Usually made of durable vinyl or rubber, these mats cushion glassware and dishes, preventing cracks or chips should they fall. Sink liners also prevent smaller kitchenware from falling down the drain while providing adequate space for water to flow into the drain.
