Thermoplastic is a strong, hardwearing plastic with a smooth looking appearance. All of our Thermoplastic seats have a quick one button release hinge. This makes them easily removable to allow thorough cleaning. The seats have secure hold rubber based hinges. Together with the tight grip plastic locking plugs, these prevent the seat from moving once fitted. The hinges are 360 degrees adjustable and have both top and bottom fixings allowing the seat to fit most types of toilet pans.
