Grohe 45203000 Cartridge Extension Set - 200mm

Summary

Grohe 45203000 Concealed Valve Extension Set 200mm

Grohe 45203000 is a 200mm concealed valve extension set used where a supported GROHE concealed valve is installed too deeply behind the finished wall for the standard trim connection. The set extends the operating connection between the concealed valve and the exposed control components.

The extension components can be shortened during installation to suit the required finished-wall depth. Check the concealed valve or trim code and establish the required extension depth before cutting or fitting the components.

Before Ordering

Check the exact GROHE valve or trim code and the required extension depth before ordering. Do not identify 45203000 from connection size or installation depth alone. GROHE 45202000 is a separate 80mm extension set and is not a superseding code for 45203000.
