Smart_DesignSmart design that cleans the whole bowl

GROHE toilets have a flush that gains extra cleaning power from its unique design. Instead of one water source, PowerFlush uses three water outlets in the bowl to create a vortex of water that cleans every inch of the bowl. Add to that the toilets’ rimless design, which means there are no hidden corners for dirt to inhabit, and this promises the most efficient flush for a clean bowl every time.


Easy to control, via the remote control or app

It’s easy to select your preferred spray and cleaning options in a choice of simple-to-operate ways. Use the intuitive remote control to adjust your settings, or download the smartphone app to create a user profile that means your shower toilet will remember your personal preferences every time.




Auto operation for low-maintenance and convenience

Convenience and low-maintenance are guaranteed thanks to automatic features – a sensor automatically opens the lid as you approach, and closes the seat after use and the spray heads are automatically cleaned before and after each use. There is also the option to add sensor-controlled automatic flushing (requires GROHE Sensia Arena automatic flush connection kit 46944000 for the Rapid SL installation system 39112001).
