Unlike traditional toilet flanges, the patented Culwell Flange toilet flange seals to the floor and resists corrosion and breakage (withstanding more than 1,000 lb.), preventing costly water damage under and around the toilet and into the subfloor/ceiling below. The Culwell Flange design originally was engineered to address a solution for people with mobility challenges in small spaces by creating a wet room and waterproofing the entire bathroom floor.
