Types of Concealed Cisterns

  • Concealed cisterns come in several types to suit different bathroom layouts and preferences.
    1. In-wall concealed flush tanks are installed within the wall cavity, providing a seamless, floating appearance for wall-hung toilets.
    2. Under-counter or cabinet-mounted models fit beneath vanities or inside bathroom furniture, ideal for back-to-wall toilets.
    3. Ceiling-mounted concealed cisterns are less common but used where wall space is limited. Slimline models are designed for narrow wall cavities or compact bathrooms.

    Each type offers compatibility with various flush plates and mounting frames, ensuring flexibility in installation and design while maintaining a clean, modern look as part of your modern bathroom accessories.

Benefits of Using Concealed Cisterns

Concealed cisterns offer numerous benefits that make them highly sought after as modern bathroom accessories.

  • Their hidden installation maximises floor space and creates a sleek, minimalist aesthetic, making even small bathrooms feel more spacious and uncluttered.
  • The concealed design reduces exposed surfaces, minimising dirt and bacteria accumulation and promoting better hygiene.
  • Many models feature dual flush mechanisms, allowing users to select between a full or half flush, significantly reducing water consumption and supporting eco-friendly practices.
  • Durability is another key advantage because concealed flush tanks are typically constructed from high-quality, corrosion-resistant materials, ensuring long-lasting performance and resistance to leaks.
  • The design also contributes to quieter operation, as the wall or cabinetry muffles flushing and filling noises, enhancing comfort and privacy in the bathroom environment.
  • Maintenance is made easier with accessible flush plates or panels, allowing repairs or adjustments without dismantling the entire wall.
  • Wall hung toilet cisterns are versatile, suitable for both wall-hung and back-to-wall toilets and adaptable to various bathroom styles, from residential to commercial settings.

How Install a Concealed Flush Tank

Installing a Concealed Flush Tank requires proper planning, accurate alignment, and secure plumbing connections. Follow this step-by-step method for a safe and efficient installation.

Step 1: Choose the Right Wall or Partition

  • Select a strong and stable wall or partition that can support the weight of the toilet and mounting frame.
  • For wall-hung toilets, ensure the wall structure is suitable for load-bearing installation.

Step 2: Mark Installation Points

  • Refer to the manufacturer’s instructions and mark the fixing points carefully.
  • Ensure proper alignment with water inlet and waste outlet connections to avoid plumbing issues later.

Step 3: Fix the Mounting Frame

  • Secure the mounting frame firmly to the wall using expansion bolts.
  • Use a spirit level to confirm the frame is perfectly vertical and stable.

Step 4: Connect the Water Inlet & Waste Pipes

  • Attach the water inlet pipe to the flush tank.
  • Connect the waste outlet pipe to the toilet pan.
  • Ensure all joints are tightly secured and leak-free.

Step 5: Install the Concealed Cistern

  • Mount the concealed cistern onto the frame and connect it to the hydraulic flushing system.
  • Double-check all connections for proper fitting and alignment.

Step 6: Install the Flush Plate or Button

  • Fix the flush plate or control button in the designated opening.
  • Ensure it remains accessible for operation and future maintenance.

Step 7: Test the System

  • Turn on the water supply and test the flushing mechanism.
  • Inspect all joints and connections carefully to ensure there are no leaks and the flush works smoothly.

Step 8: Conceal the Frame

  • Once testing is complete, cover the frame and cistern using plasterboard or a suitable wall panel.
  • Finish the wall surface with tiles or other desired materials.

The flush plate will remain visible for operation and maintenance access.

Proper installation of a concealed flush tank ensures reliable performance, water efficiency, and a clean, modern bathroom look—perfect for enhancing contemporary bathroom accessories and interiors.
