GROHE Whisper® technology ensures maximum design flexibility. The water outlet pipe prevents noise transfer to the building structure when water flows from the cistern to the toilet bowl. This makes it an ideal choice for the bathroom. All concealed cisterns come with an integrated overflow. In the event of a problem, the water will flow into the toilet bowl, not onto the floor. The GROHE SpareFlush allows you to increase the fixed water volume from 6 liters to 9 liters if needed. This ensures compatibility with all sanitary ware and meets any hydraulic installation requirements. For maximum user convenience, there is also an air button activation option available, which can be located up to 1.5 meters away from the cistern. One of the easiest ways to save water is by installing a GROHE cistern and a dual flush actuator plate. Due to GROHE EcoJoy™ technology, our cisterns allow you to significantly reduce annual water consumption by selecting the appropriate water quantity each time you flush. The cisterns are factory-set for dual flush with 6 liters (full flush) and 3 liters (half flush). The water volume can be adjusted to ensure compatibility with all sanitary ware and installation requirements.
