GROHE Rapid SL installation system for your toilet – easy installation, even under windows

Easy-fitting and total stability are just the start with the GROHE Rapid SL installation system for wall-hung toilets. You’ll also love the eco-benefits and noise-lowering feature. 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 inside 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. With a low height of only 0.82 m, this system can even be installed under windows. 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. If required, please purchase the 3855800M wall bracket to install this system. Choose from over 130 attractive flush plate designs to complete the installation.
