Grohe 35015000 Grohsafe Universal Pressure Balance Shower Valve Rough-In Kit

Mario T: Great quality, warranty and customer service. My cartridge leaked but Grohe sent me a replacement. It took a long time to arrive though thus the 4-star rating.

Marty CMarty C: I purchased a Grohe shower trim kit with this universal adapter and my plumber handed it back to me saying it was incompatible. After it was installed and subsequently removed. A painful lesson to the pocket book. Thanks for the recommendation, Amazon!

C. A. Walker: Just installed it yesterday. It installed quickly, I've had no leaks thus far but will do another test before closing up the wall.

2018: I bought this previously for another Grohe installation, and it was pictured along with the new shower system under “often purchased together”. But I don’t need it, mixer is outside the wall on new system. Can’t return it now. Call Grohe, make sure you need it.

dps: The directions are not very user friendly. Many small pictures and in a separate section, written directions. It would be helpful to combine the pictures with the directions to make installation process clearer. Following the placement shown, the valve had to be installed on a 2 x 6 attached behind the wall studs, in order for it to be set back at the specified depth. Luckily we had the space behind the studs. Then we had problems with the valve trim-- the escutcheon plate screws were way too short, and the metal sleeve that the handle seats to was too long. Luckily there was a white plastic ring behind the sleeve that we cut out, making the sleeve sit farther back so the handle would fit correctly. NO directions about how to adjust for depth. The biggest mystery is why the screws are so short. There's no reason a longer screw couldn't be used because there is space behind the hole they screw into. Because the screw is finished in chrome, and metric, it's impossible to find a longer replacement locally, and Grohe told us that only that length was available. We had to use what we could find at the hardware store. Grohe makes a very solid product but their engineering tolerances are...

King Chan: The faucet cartridge in my washroom broke. I couldn't find a replacement cartridge anywhere and ended up buying this set which is pretty expensive for what I needed. Anyway, it's easy enough for me to replace it myself since after 15 months my installation is out of warranty. Incidentally, my Grohe kitchen faucet cartridge also broke after 3 months of use. It was under warranty and the repair guy replaced the entire faucet.

crane_critter: I've taken this thing apart and I've read the instructions over and over and couldn't figure out how to regulate how much hot water is mixed in this valve. Turns out it's not in the rough-in instructions that comes with. Now, that doesn't make any sense. However the maximum hot water limit setting is described how to be set in the instructions on how to install your shower handle. It would make sense to have it in both. I like the construction and even a homeowner can easily take apart and put it back together without a fuss. I just can't love it because an important part of the function of this piece of hardware isn't even in the instruction manual. To those that are confused, when you take the handle off of your shower, it's the black threaded plastic piece with a loop in the default position at 2 O'clock. It can be taken off and rotated counter clockwise to find your preferred heat level.
