The Bemis 5000 Range Chicago toilet seat is crafted from moulded wood with a durable Thermoset surface. This seat features a patented STA-TITE fixing system designed for a simple, mess-free installation that prevents loosening over time. Made with responsibly sourced woods and water-based paints, it is environmentally friendly and naturally anti-bacterial. The adjustable plastic hinges allow it to fit the majority of manufacturers' universal shaped pans. Its hard-wearing, water-resistant construction ensures it won't swell or split like less durable alternatives.
