GROHE Rapid SL installation system with Whisper technology for a quieter flush

Take confidence and comfort from the smart design and strength of the GROHE Rapid SL 3-in-1 installation set for wall-hung toilets. Even fitting it is straightforward. The steel frame is certified to hold loads of over 400 kg for ultimate stability and it can be installed in front of a solid wall or within a stud wall in next-to-no-time thanks to the GROHE QuickFix system, which requires no tools to connect hose, inspection shaft and water supply. The GROHE EcoJoy dual flush system is kinder to the environment, reducing water consumption by up to 50%. Noise transmission to the building is kept to a minimum thanks to GROHE Whisper technology, engineered with low-noise fittings and separate plumbing. The set comes complete with wall brackets and an attractive Skate Cosmopolitan chrome flush plate.
