## Long description

GROHE Rapid SL wall-frame model 38994000 is an in-wall support frame designed for mounting wall-hung toilets and integrating concealed cisterns. The frame is made to provide a stable, load-bearing structure for wall-mounted WC pans and installation of flushing systems, enabling a flush finish and space-saving layout for residential bathrooms and public restrooms. It is compatible with GROHE fixtures and follows standard mounting dimensions for reliable fitment.
Advantages
The frame offers robust structural support for wall-hung toilets while allowing the cistern and plumbing to remain concealed within the wall. Its design facilitates a flush appearance and frees up floor space, which simplifies cleaning and creates a minimalist look. Installation is intended to be straightforward for trained installers, with standardized mounting points and compatibility with a range of wall-hung WC pans and flush plates from the same manufacturer.
