The straight-through design without a trap simplifies the drainage path, has low resistance to sewage discharge, fast water flow speed, can quickly remove dirt, reduce the risk of blockage, and lower maintenance costs. The sewage outlet is located behind the toilet bowl. Excrement first enters the bottom sink and then flows out downstream, which is cleaner and can be adapted to the layout of the rear sewage pipe without the need for significant changes to the original pipeline. The elimination of the trap structure makes the product thinner and lighter. The rear-mounted drainage design reduces the occupation of wall space and is convenient for matching with other bathroom facilities such as washbasins and storage cabinets, making the small bathroom more organized. The tread area is carefully polished with anti-slip stripes to increase the friction on the soles of the feet, preventing slipping due to wet ground during use and ensuring the safety of the elderly and children.
