Product Description

GROHE Rapid SL installation system for low-height installation under windows

Installed in the blink of an eye thanks to the GROHE QuickFix concept, this Rapid SL installation system for your toilet offers maximum convenience right from the start. No tools are required to connect water supply, hose and inspection shaft. With a certified load-bearing capacity of over 400 kg, the steel frame is perfectly safe for your home. Mounted in front of a solid wall or inside a stud wall, it will reduce your water consumption by up to 50% thanks to the GROHE EcoJoy dual flush. Thanks to its low height of only 0.82 m, it can even be installed under windows. The GROHE Whisper noise control minimizes sound transmission to adjoining rooms. With the concealed tank and a wall-hung toilet, your bathroom cleaning will be easier than ever. This set comes complete with the Skate Cosmopolitan chrome flush plate.

Product Highlights

The GROHE Whisper concealed cistern guarantees noise control

With its low-noise fittings and decoupled piping, GROHE Whisper technology prevents sound travelling through walls. The low noise level of only 21 dB(A) undercuts the standard requirement of 24 dB(A) so you will enjoy total peace and quiet!

Save water and save money with GROHE EcoJoy

It’s time to cut your water usage – and your water bill – by up to 50% with GROHE EcoJoy flush technology. Select a flush volume of either 3l or 6l (or 3l and 4.5l, depending on the ceramic body) and, if you want, stop a full flush before it’s over.

Added flush volume for a more effective flush

Give the flush on your toilet a boost with the GROHE SpareFlush system, which provides an extra 3l of water – even in buildings with old plumbing.

Connect with ease in seconds – that’s ToolFree

No tools are needed to connect your water supply, flexible hose and inspection shaft. That’s our innovative ToolFree concept.

A concealed system that’s simple to install – that’s GROHE QuickFix

GROHE QuickFix makes installing a concealed system quick and easy. In a test of installation times carried out by Germany's REFA association it outperformed competitors by up to 155%!

GROHE Rapid SL toilets can take a load of 400 kg

Safety is the name of the game with your GROHE Rapid SL installation system. The steel frames of the wall-hung toilets and basins are certified to hold up to 400 kg and 150 kg, respectively.

The choice of 130 complementary designs

The universal base plate matches all our flush plates so you can choose from over 130 attractive designs. They are also easy to install and can be mounted either horizontally or vertically.

Connect the flush plate and drain valve easily with EasyConnect

There’s no need to measure or cut the hose because it simply plugs onto the drain valve and flush plate. Smart and simple. That’s EasyConnect.

Concealed cistern connection made simple!

With our VarioPort system you the supply hose to the water supply at four points: front, rear, left and right. Simple. Fast. No hassle.

Easy installation with a single drain valve

With a single drain valve for all flush modes – including single flush, dual flush and start-stop technology – mounting the installation system is quick and easy.

High shine chrome coating makes cleaning easy

GROHE Starlight chrome coating on taps means you can just wipe them down with a dry cloth – no marks, no streaks, no water spots. The ultra-bright surface is scratch-resistant so will keep its original lustre with minimal maintenance.
