The NC toilet seat is made of urea resin, a long-lasting, durable and environmentally friendly material. A mild soap solution and a soft cloth are ideal to thoroughly clean the hygienic, non-porous surface without leaving any residues. TOTO designed its toilet seats to be removed quickly and easily – for simple, thorough cleaning. It takes just a push of the release buttons to detach the seat from the ceramic toilet bowl and access any hard-to-reach places. The stainless steel hinges are corrosion-resistant – an essential component to keep the seat securely attached to the toilet bowl for years to come.
