This cartridge is for a Grohe 3/4" volume control. I bought about five of them. The one operating the main shower valve in the master shower was a problem. It stuck and wouldn't easily turn completely off. Then all of the sudden it worked. Great, now I don't have to call the plumber back!. Charles Dorfman. Kansas City. Tue Oct 21 2025

worked perfectly to fix my 20 year old shower!. Sherry. Glen Ellyn, IL. Tue Jan 25 2022

The GROHE GrohSafe 3.0 Shower Rough-in Valve is engineered for quick, easy installations no matter the situation. Compact body allows for a hassle-free fit even in tight spaces. Flat back ensures solid mounting on a standard cross brace, and installation on thin walls or steel is sturdy and secure. Made of DZR brass to resist corrosion, the GrohSafe 3.0 is equipped with a flush plug that allows you to test and flush lines with ease. Stainless steel fixation ring keeps flush plug and cartridge in place without screws. Cartridge sold separately.
