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 with ToolFree feature, 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. To install this product, please purchase the 3855800M wall brackets. Choose from over 130 attractive flush plate designs to complete the installation.
Sound transmission to adjoining rooms minimized with GROHE Whisper noise control
Thanks to low-noise fittings and decoupled piping, the GROHE Whisper technology prevents any sound transmission to adjoining rooms, leaving the other occupants of the house undisturbed. Undercutting the standard requirement of 24 dB(A), this system's low noise level of only 21 dB(A) was confirmed by Germany's renowned Fraunhofer research organization. The Rapid SL stud wall installation even reached a low-noise record of 14 dB(A).
Reduce your water consumption by up to 50% with GROHE EcoJoy and pay a smaller utility bill
The GROHE EcoJoy flush technology reduces your water consumption by up to 50%. The dual flush system provides two buttons, allowing you to select a flush volume of either 3 or 6 litres (or 3 and 4.5 litres, depending on the ceramic body). Using the small button on the flush plate, it is also possible to stop a full flush prematurely.
Reduced installation time thanks to GROHE QuickFix
The GROHE QuickFix concept ensures flexibility and ease of installation, cutting installation time significantly. The Rapid SL system scored top marks in a practical test carried out by Germany's REFA association, outperforming competitors by up to 155% with respect to the time taken to complete the installation.
Rapid SL installation systems with Safety feature are safe for loads of over 400 kg
Safety is the name of the game with your GROHE installation system. The dimensional stability and load-bearing capacity of the steel frames were tested and the Rapid SL installation systems for wall-hung toilets and basins were certified to hold over 400 kg and up to 150 kg, respectively.
Quick and tool-free connection of water supply, flexible hose and inspection shaft
Connecting the system is super easy with our ToolFree concept: no tools are needed to connect water supply, flexible hose and inspection shaft.
SpareFlush: additional flush volume for an effective flush, even with old plumbing
Flushing a toilet effectively can be a challenge in buildings with old plumbing. The SpareFlush system provides a solution to this problem: in addition to the regular 6-litre flush volume (or 4.5 depending on the ceramic body), it provides an extra volume of 3 litres, ensuring an effective flush, even with old plumbing.
Pneumatic hose easy to plug onto flush plate and drain valve with EasyConnect
Connecting drain valve and flush plate is super easy with our EasyConnect system. No need for tedious measuring or cutting the hose down to the right length. The pneumatic hose simply plugs onto the other elements. Smart and easy.
Quick and easy water connection with VarioPort
Save time with a VarioPort water connection: irrespective of position of the supply pipe, the supply hose can be attached at four points: front, rear, left or right.
Universal base plate to match all flush plates
The universal base plate matches all our flush plates, allowing you to choose from over 130 attractive designs. All flush plates can be mounted either horizontally or vertically, even without tools, as the inspection shaft can be installed both ways.
Easy installation with a single drain valve for all flush modes
With a single drain valve for all flush modes – single or dual flush, start-stop technology – mounting the installation system is simple and hassle-free, leaving no room for mistakes.
