Do it Best 431125 Rubber Sink Stopper 5-Inch White

5-Inch Rubber Sink Stopper for Standard Drains

The Do it Best 431125 is a white rubber stopper with a five-inch outer diameter designed to seal kitchen or bathroom sinks. Its flat suction-grip base creates a watertight seal without hardware or tools. The carded packaging keeps the unit clean until installation. It suits homeowners and renters needing a simple, reusable drain plug for everyday use.

Limited to Flat Surfaces and Single-Basin Use

The suction grip requires a smooth, flat drain opening to hold pressure; textured, sloped or overflow-equipped basins may prevent a reliable seal. The fixed five-inch diameter cannot stretch to fit larger or irregular openings, and no chain or tether is included to prevent loss. Buyers with non-standard drain sizes or double-bowl sinks needing simultaneous sealing should verify dimensions before purchase.
