Wall Hung Toilet Cistern

When designing a modern, minimalist bathroom, the details often make the biggest difference. One trend that has seen a massive surge in popularity is the concealed cistern. But what exactly is it, and is it the right choice for your home or commercial project? In this guide, we’ll break down everything you need to know about concealed cisterns—from their practical benefits to their potential drawbacks.   What Is a Concealed Cistern? Simply put, a concealed cistern is a toilet water tank that is hidden behind a wall, inside a furniture unit, or within a mounting frame. Unlike traditional "close-coupled" toilets where the tank is visible and sits directly on the bowl, only the toilet pan and the flush plate are visible in a concealed setup. How it works: The cistern is installed within a cavity (usually about 150mm deep). It is connected to the toilet bowl through the wall. Instead of a lever, you operate the flush via a flush plate—a stylish panel mounted on the wall.   The Pros: Why Choose a Concealed Cistern? 1. Aesthetic Minimalism The most obvious benefit is the look. By hiding the bulky plastic or ceramic tank, you achieve a sleek, high-end "hotel look." It creates clean lines and reduces visual clutter. 2. Space Saving Because the tank is recessed into the wall, you can save up to 10-20cm of floor space. This is a game-changer for small powder rooms or narrow en-suites where every centimeter counts. 3. Easier Cleaning Traditional toilets have nooks and crannies between the tank and the wall that act as dust traps. With a concealed cistern (especially when paired with a wall-hung toilet), the floor underneath is clear, and there are fewer surfaces to wipe down. 4. Noise Reduction Since the cistern is encased behind a wall or cabinetry, the sound of the tank refilling is significantly muffled, providing a quieter experience.   The Cons: What to Consider Before Buying 1. Installation Complexity Installing a concealed cistern requires more labor than a standard toilet. You may need to build a stud wall (false wall) to house the tank, which adds to the initial renovation cost. 2. Accessibility Concerns A common myth is that you have to "smash the wall" to fix a leak. While modern units are designed so you can access the internal valves through the flush plate opening, major structural repairs could still be more difficult than with a visible tank. 3. Higher Price Point The cistern, the mounting frame (for wall-hung versions), and the designer flush plate generally cost more than an all-in-one traditional toilet.   Applications: Where Does It Fit Best? Small Bathrooms: To maximize floor area and create an illusion of space. Luxury Residential Projects: For homeowners looking for a premium, contemporary finish. Commercial Restrooms: In high-end restaurants or offices where hygiene and aesthetics are top priorities. Universal Design: Wall-hung frames allow you to set the toilet height precisely, which is helpful for creating accessible bathrooms for the elderly or those with mobility issues.
