The Grohe Rapid SL installation frame is the ideal installation solution for wall-hung toilets – it includes a sturdy steel frame, a flushing cistern, a stylish Nova Cosmo flush plate, and mounting brackets, so you’ve got everything you need to securely install a wall-hung toilet. This system is just what you want when you want to create a modern look in your bathroom by keeping your toilet off the floor (which means it’s easier to clean and feels more spacious too). Plus, this frame can support up to 400kg, ensuring plenty of strength and stability.

QuickFIx Technology

The Rapid SL frame makes installation much simpler, giving you flexibility whether you’re installing against a solid wall or in front of a stud wall. And thanks to Grohe’s QuickFix system, setup is fast and tool-free, making it ideal for DIY or professional installers.

Modern Flush Plate

The accompanying Nova Cosmo flush plate has a clean, modern design, and you can choose whether to install it vertically or horizontally, depending on your style preference. You’ll also be able to control water usage as it’s a dual flush plate; you can choose a smaller or larger flush.

Whisper Quiet

With this setup, noise will be kept to a minimum thanks to the specially designed quiet technology included, so you can enjoy even more comfort and convenience by choosing the Grohe installation frame set.
