To combine the cistern with small flush plates (Skate Cosmopolitan S, Nova Cosmopolitan S, Arena Cosmopolitan S, Skate Air S), the 40949000 adapter is required.
For maximum comfort, GROHE installation systems deliver outstanding performance.
GROHE Whisper® technology provides maximum design flexibility. The water outlet pipe prevents the transmission of flushing noise to the building structure as water flows from the cistern to the toilet bowl, making it an ideal solution for modern bathrooms.
All GROHE concealed cisterns feature an integrated overflow. In the event of a malfunction, excess water is safely discharged into the toilet bowl rather than onto the bathroom floor.
GROHE SpareFlush allows the standard 6-litre flush volume to be increased to 9 litres whenever required. This ensures compatibility with all sanitaryware and a wide range of plumbing installations.
For maximum user convenience, pneumatic flush activation is also supported, allowing the flush button to be installed up to 1.5 metres away from the concealed cistern.
One of the easiest ways to reduce water consumption is to install a GROHE concealed cistern together with a dual-flush activation plate.
Thanks to GROHE EcoJoy™ technology, our concealed cisterns help significantly reduce annual water consumption by allowing you to select the appropriate flush volume every time. They are factory-set for a dual flush of 6 litres (full flush) and 3 litres (half flush). The flush volume can also be adjusted to ensure compatibility with all sanitaryware and installation requirements.
