Once activated, the flush completes its full 6-litre cycle regardless of button release, ensuring thorough waste removal every time. This prevents partial flushes that can lead to hygiene issues and reduces the need for multiple flushes, ultimately saving water despite being a single-flush system. Side Fill Configuration: Installation Flexibility: The side fill design allows water supply connection from the left, right, or back of the cistern. This is particularly valuable for commercial installations, retrofit projects, furniture-mounted WC units, and situations where existing pipework positioning dictates inlet location. The flexible connection options simplify plumbing and reduce installation time. Grohe Starlight Chrome Finish: The Grohe Starlight chrome finish delivers exceptional durability through multiple layers of premium chrome plating. This creates a finish that resists scratching, tarnishing, and corrosion whilst maintaining its mirror-like lustre. Easy to clean and maintain, Starlight chrome is engineered to withstand demanding bathroom environments, making it ideal for both commercial and residential applications. Technical Advantages: Commercial Grade Construction: Built to withstand high-frequency use, this cistern is ideal for commercial washrooms, public facilities, offices, and high-traffic residential bathrooms. The robust mechanism and non-interruptible flush ensure consistent performance even with intensive daily use. Low Pressure Compatibility: With a minimum recommended static pressure of just 0.2 bar, this cistern works reliably even in properties with lower water pressure, ensuring consistent flush performance across all installations. ABS Flush Pipe: The included ABS (Acrylonitrile Butadiene Styrene) flush pipe offers superior durability compared to standard plastic pipes. Resistant to impact, chemicals, and temperature variations, the 180mm × 320mm pipe ensures reliable connection between cistern and WC pan. Perfect For: Commercial washroom installations Public facilities and offices High-traffic residential bathrooms Back-to-wall toilet systems Furniture-mounted WC units Retrofit projects with side pipework Hotels and hospitality installations Schools and educational facilities Healthcare and care home bathrooms Applications requiring non-interruptible flush Single Flush vs Dual Flush: This 6-litre single flush model is ideal for commercial applications where consistent flush volume is required, or where simplicity and reliability are priorities. The non-interruptible cycle ensures complete waste removal every time. For residential applications prioritising water efficiency, consider Grohe's dual flush models (39053000 or 39054000) which offer 6L/3L options.

No separate button purchase is required, unlike some other Adagio cistern models. What is the difference between side fill and bottom fill? The side fill inlet (this model, 39054000) accepts the water supply connection from the left, right, or back of the cistern — useful for furniture installations, retrofits, or where pipework enters from the side. The bottom fill model (39053000) connects from below, which is standard for new builds with floor-level pipework. Flush performance is identical on both. What wall thickness is this suitable for? This cistern is designed for walls between 18mm and 24mm thick, covering standard stud wall and bathroom furniture panel constructions. What is EcoJoy technology? EcoJoy is Grohe’s dual flush system delivering a 6 litre full flush and a 3 litre half flush. Choosing the half flush for liquid waste reduces water consumption by up to 50% compared to older single-flush cisterns, lowering utility bills and reducing environmental impact without compromising flush performance. What is Acoustic Group I? Acoustic Group I is the quietest classification for cistern fill noise under European standards. It means the cistern refills quietly after flushing — particularly important for ensuites, apartments, and bathrooms adjacent to bedrooms. What is the minimum water pressure required? A minimum static pressure of 0.2 bar is required, making this cistern compatible with most UK water supplies including properties with lower pressure. Can I order if the item shows as out of stock? Yes — this product is available to order even when stock shows as zero. Please allow additional lead time and contact us on 01603 381095 to confirm availability and delivery timescales.
