The Ideal Standard ProSys Concealed Cistern is built with the reliability and engineering that define Ideal Standard’s approach to bathroom design. Designed for use with a range of back-to-wall toilet pans, it offers a discreet and practical way to achieve a clean, uncluttered look.

This 120 mm deep dual-flush cistern is installed within the wall, leaving only the toilet pan and your chosen flush plate on show. The result is a modern, space-saving setup that’s easy to maintain.

The cistern features a mechanical dual-flush system, allowing you to choose between a full or half flush for improved water efficiency. It’s built from robust, long-lasting materials that ensure dependable performance over time, even in high-use environments. The side water inlet connection provides flexibility during installation and helps accommodate a range of bathroom layouts.

With simple access for servicing and compatibility with Ideal Standard’s range of flush plates, the cistern brings together durability and convenience. It’s an ideal choice for both residential and commercial bathrooms where reliability, performance, and a tidy finish are equally important.
