The Culwell™ Flange

Product Overview

Designed by a master plumber, the Culwell Flange is the new standard in closet flanges because it takes property protection into account. It is the only closet flange that seals to both the floor and toilet, creating an impenetrable water-tight seal in bathing, toilet and sink areas.

The proprietary design works to prevent leaks, water damage and costly repairs. It's the only product on the market that protects the property by design, thus saving building owners and property managers thousands of dollars in time and repairs over the life of the property.

For specifying architects and engineers, the Culwell Flange provides a complete, IAPMO certified, cUPC-approved water seal solution, offering increased value to clients, while decreasing liability exposure and is ideal for wet room, healthcare and bariatric applications.

Property owners and managers appreciate avoiding water damage altogether. The Culwell Flange saves rental down time/turnover and reduces liability and repair expenses.

No other product on the market seals to the floor!
