Bathroom Basin Drainer Stopper Vanity Waste Drain Vessel Sink Pop up Drain with Overflow

We are a professional bathroom sink drain factory offering a full range of drainage solutions. Our main products include pop-up drains (with lift rod), push-button drains, grid drains, and basin wastes. We also supply complete drain assemblies with overflow and without overflow options to meet different sink designs .

We use high-quality materials to ensure durability and corrosion resistance. Our drains are mainly made of SUS304 stainless steel (excellent rust resistance) and solid brass (ASTM B124 standard). For brass drains, we offer various surface finishes including polished chrome, brushed nickel, matte black, and PVD-coated rose gold/gunmetal .

The most common standard sizes are 1-1/2' (inch) and 1-1/4' with NPSM threads for North American markets, or M32 x 1.5 and M40 x 1.5 metric threads for European/Asian markets. We can produce custom thread types (BSP, NPT) based on your target market requirements .

A drain with overflow has small holes or a side inlet that allows water to enter the drain from the top if the sink fills too high, preventing flooding. A drain without overflow is solid and used for sinks that have a separate overflow hole in the sink itself. Please check your bathroom sink design before ordering .

A P-trap is the curved pipe that retains water to prevent sewer gas from entering the bathroom. Yes, we offer complete drain kits including the drain body, stopper, tailpipe, P-trap, and mounting hardware. This provides a one-stop solution for your bathroom sink projects .
