GROHE Whisper®

Innovative water technology delivering whisper-quiet acoustics.

All GROHE concealed systems feature GROHE Whisper® Technology. Decoupled pipe supports prevent sound transfer to the structure of the building when water is released from any GROHE concealed cisterns into the bowl.
There is no risk of noise disturbance so that you can plan your bathroom exactly how you want and ensure your WC is in the location you decide, not where restrictions dictate.
This GROHE technology ensures that there is no irritating noise or water hammering.
