Vortex floor-drain is an innovative product with a simple shape and practical function. In terms of shape, the square and round independent covers are exquisite and simple, and can be freely matched in multiple scenes. In terms of structure, the annular water tank, larger caliber, and internal spiral structure allow the product to discharge water more quickly. The product has a double sealing structure, and the gravity flip structure at the drain can quickly close the seal after drainage, effectively preventing unpleasant odors from entering the room. The rotary disassembly structure makes it easier and faster for users to disassemble and clean.
