This hollow rubber sink stopper from Larsen Supply provides a simple, effective seal for bathroom lavatory and small utility drains. The flexible white rubber compresses to grip the drain rim, and the hollow chamber lets water pressure expand the stopper into the opening for a watertight fit. A handy alternative when the original mechanical pop-up is broken, missing, or when you simply need to fill the basin for hand-washing, soaking, or shaving.

• Hollow rubber construction grips the drain rim and seals under water pressure
• White finish blends with most porcelain, ceramic, and acrylic basins
• Fits drain openings from 1" to 1-1/8" - measure the inside diameter of your drain rim to match
• Best for: Compact bathroom lavatories and half-bath drains
• Use in bathroom lavatories, half-baths, bar sinks, and small utility basins
• No tools or installation required - drop in and lift out by the top loop

Sizing tip: Measure the inside diameter of the drain opening (not the basin) at the rim. If your drain measures between two listed sizes, choose the smaller stopper - the hollow rubber expands under water pressure to seal a slightly larger opening, but an oversize stopper will not seat at all.

Drain Size: 1" to 1-1/8"
