The pop-up drain for sinks is made of brass with a chrome-plated and smooth surface, robust and durable. The push-button drain is corrosion, rust, and high-temperature resistant and can be used for a long time. The bathroom drain with pop-up function has a good bounce. It can be easily closed or opened by pressing the retractable lid. The sink can be filled with water when closed, and the lid can be quickly emptied by pressing the lid again. We use an exquisite mirror-like silver finish, giving you a comfortable feel. The bathroom drain is easy to install; just insert the plug button into the sink opening, and you can easily connect and use it. The drain valve has a waterproof white silicone ring, which has good sealing performance. The basin stopper can prevent water leakage and prevent pipe blockages caused by food residues. It is suitable for sinks with 36-39 mm drain holes. The pop-up drain for bathrooms is perfect for bathroom sinks, office corridors, kitchen drains, and others.
