Wash Basin Sink Overflow Hole Cover Ring & Trim Insert Cap

Give your bathroom or kitchen sink a clean, polished look while maintaining proper drainage safety with a replacement sink overflow hole insert cap. Our wash basin overflow ring and sink hole insert cap set covers unfinished overflow drainage ports on ceramic basins, vanities, and bathtubs. Engineered with flexible, high-grip retention prongs, the cap pushes smoothly into standard round overflow openings, locking firmly into place without slipping or floating out when water levels rise. The protective trim ring conceals discolored tile edges and raw ceramic porcelain, providing a decorative accent that seamlessly matches chrome, brushed nickel, or matte faucet hardware. Crafted from corrosion-resistant, high-impact ABS polymer with an electroplated finish, this trim cap withstands continuous water exposure, soap scum, and household bathroom cleaners without peeling or rusting. Refresh your sink fixtures effortlessly with a tool-free wash basin overflow trim insert cap designed for instant snap-in installation.
