The toilet seat, made entirely of duroplast, closely resembles the more affordable version made of polypropylene. This product has been designed with an innovative design where the seat cover partially overlaps the seating, creating a cascading surface. The dimensions of the seat are highly versatile, allowing our product to fit many types of sanitary ceramics, including compact, wall-hung, and freestanding models.


The KASKADA-BIS toilet seat is equipped with an adjustable hinge made of PP, featuring a slow-closing mechanism, also known as soft-close, allowing the seat to descend onto the ceramic surface slowly and silently. Additionally, the hinge has a quick-release function, facilitated by two buttons, enabling easy and swift removal of the seat for cleaning the ceramic. The seat has two elastomer bumpers on the lid and six longitudinal bumpers on the seat. The attachment of the seat is done from the bottom of the ceramic using polypropylene screws with an eccentric head, onto which nuts with washers are screwed.
