Stainless steel material: The shower floor drain is made of 304 stainless steel, which is corrosion-resistant and not easy to rust; the surface is treated with high-temperature automotive paint technology, finely polished to prevent paint chipping, scratch-resistant, smooth, safe for bare feet, and features a sleek, modern design. Powerful drainage: The kitchen floor drain is 20 cm long, offering fast drainage speed and high water flow capacity, suitable for daily household use and fits 90% of homes. The drain cover thickness is 1.42 mm and the base thickness is 19.18 mm, constructed with thicker, durable materials. Double filtration: The top layer features a slotted panel for quick water drainage and first-stage filtration, while the bottom layer includes a filter to catch hair and debris for secondary filtration. This dual filtration system helps prevent clogs in the sewer line. Self-closing anti-odor core: The black linear floor drain includes a flap-style drain core that operates on a gravity-based mechanism—automatically opening when water flows and closing when dry. This helps prevent sewer gases, insects, and odors from entering, promoting a healthier bathroom environment. Compatible drain pipe diameter: This floor drain fits sewer pipes with a diameter of 50–75 mm. Side-outlet design makes it ideal for corner installations. The black floor drain features a bayonet-style mounting system, allowing the cover to be easily removed for cleaning.
