What Are Siphonic Closets?
At Osaka Sanitary Ware, our siphonic closets feature a precision-engineered ‘S’-shaped trapway that seamlessly connects the bowl to the drain. This advanced design creates a powerful siphon effect during flushing, ensuring superior performance with minimal noise.
Compared to traditional wash-down models, Osaka’s siphonic closets offer a larger water surface area and a deeper water seal—delivering cleaner, more hygienic results. Crafted from premium materials and backed by cutting-edge technology, our siphonic range combines silent efficiency, contemporary design, and long-lasting durability.
