This floor drain features a bionic design inspired by natural pebbles. The drain’s round, smooth surface keeps dirt from adhering to it, prevents clogging, and is easy to clean. The surface of the drain cover and the edge of the inside frame are both curved, which widens the drain, guiding the water down the convex surfaces, accelerating drainage flow rate and increasing drainage flow. This design also improves drainage efficiency and eliminates water stains. The surface is treated with an antibacterial coating to prevent the growth of bacteria and provide a safer and more comfortable bathroom experience.
