“Pay no attention to that man behind the curtain...” are the immortal words spoken by the Wizard of Oz to Dorothy in the classic 1939 film as it is revealed that all the magic is happening behind the curtain.
For more than 100 years, Thomas Dudley has been providing the magic behind the curtain. In the world of washrooms and bathrooms, that curtain is often a concealed cistern hidden behind a wall, within furniture, or integrated into a modern installation. While unseen by the end user, these products play a vital role in delivering reliable performance, water efficiency and long-term durability.
Innovation has always been at the heart of Thomas Dudley’s product development philosophy. Combining engineering expertise, manufacturing excellence and a commitment to continuous improvement, the company has become one of the UK’s most respected names in plumbing and washroom solutions.
Today, Thomas Dudley offers the widest range of concealed cisterns available on the UK market, providing installers, merchants, contractors and specifiers with solutions for virtually every application imaginable. Whether the requirement is for furniture-mounted installations, wall-hung sanitaryware, duct-mounted systems, corner applications, IPS panels or bespoke commercial projects, Thomas Dudley has a solution designed to meet the challenge.

At the heart of this offering is the renowned Vantage range of concealed cisterns. WRAS-approved and trusted across both domestic and commercial environments, Vantage cisterns combine reliability, installation flexibility and water-saving performance. Designed to be installed behind walls, furniture, tiles and partitioning systems, they provide the versatility required for modern bathroom and washroom design.
Complementing the cistern range is the Thomas Dudley Illusion A Frame, the most adjustable WC support frame in the UK, engineered for both flat-wall and corner installations. Designed to work seamlessly with Thomas Dudley concealed cisterns, the frame offers exceptional flexibility, with adjustable height settings between 825mm and 1120mm. This enables installers to create bespoke solutions while simplifying specification and installation on site.

While the cistern is often hidden from view, it can be paired with an extensive range of flush actuation options. Thomas Dudley offers a comprehensive selection of flush plates, push buttons, levers and electronic controls to suit every aesthetic and performance requirement.
One such example is the Wave S3 electronic touch-free flush plate. Designed for modern commercial and domestic washrooms, the Wave S3 combines contemporary styling with touch-free operation to enhance hygiene and user experience. Featuring intelligent dual-flush functionality, low-energy operation and customisable flush icons, it demonstrates Thomas Dudley’s commitment to combining innovation with practical performance.
However, what truly sets Thomas Dudley apart is not just individual products but the breadth of solutions available. By offering the UK’s most extensive concealed cistern portfolio, the company enables customers to source complete, compatible washroom systems from a single trusted manufacturer.
