This premium pop-up drain assembly features a reinforced design with all-metal construction for maximum durability and long-lasting use. This drain assembly fits standard 1 3/4-inch drain openings and is designed for use with all lavatory sinks without built-in overflow drain holes, including semi-recessed and vessel sinks. The premium design features an extended thread that allows you to install extra-thick countertops and sinks made from thicker materials like glass. This bathroom sink drain is easy to operate, with a spring-loaded pop-up stopper that opens and closes by simply pressing the top. Press down to seal off the drain opening, and press again to let water flow freely. All exposed parts of the drain and stopper are completely finished, making this drain assembly both functional and aesthetically appealing. The corrosion-resistant finish is not prone to fading or tarnishing over time and is available in a range of colors to match your bathroom faucet and create a beautifully coordinated look.
