Two flush volumes are available: Full Flush: For solid waste – typically 6 litres Reduced Flush: For liquid waste – typically 3–4 litres This dual flush system can reduce water consumption by up to 60% compared to older single-flush cisterns, lowering utility bills and reducing environmental impact. Insulated Construction The insulated cistern body prevents cold water inside the cistern from causing condensation on the outer surface — a common issue in bathrooms with high humidity. This protects surrounding wall structures and cabinetry from moisture damage and ensures a cleaner, drier installation long-term. Universal Front & Top Access Both front and top access points are provided for servicing and maintenance: Front Access: Reach internal components through the flush button aperture — ideal where top access is restricted Top Access: Full access from above for installation and major servicing Compatible WC Types Wall-hung WC pans (suspended toilets) Back-to-wall WC pans (floor-standing with concealed cistern) Standard and comfort height pans Complete the Range Pair this cistern with compatible Nuie products available in our store: Back to Wall Toilets – compatible WC pans for concealed cistern installations Nuie Accessible Toilet Pack – Doc M compliant, comfort height toilet pack About Nuie Nuie is a leading UK bathroom brand supplying quality sanitaryware, furniture, and accessories to trade and retail customers.

Yes — this cistern is supplied complete with a round 50mm chrome Starlight push button (with eco button) and a 0.5m Bowden cable. 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.
