KOHLER Rite-Temp Pressure Balance Cartridge, Genuine Part GP800881, One-Piece Design Simplifies Installation and Maintenance

The conical design with secure "O" rings allows for easy installation of this Kohler pressure balance cartridge with an exact fit. Be sure the clean the valve housing to ensure proper seating and prevent leaks. The mixer valve works smoothly and is compatible with a wide range of handle and trim options. Durability TBD but the original unit lasted about six years before the drips became a stream with a high-pitch whistle when water pressure varied in the house. The entire replacement process took about 30 minutes as a DIY home project.

I got this to fix a drip in my tub faucet. This was the exact part I needed and I got a OEM Kohler Part. Great deal and this was pretty hard to find so I am glad I was able to get it on Amazon. It is nice because the GP800881 model has all the gaskets built into it. All I had to do to install it was turn off the water, remove the old one, dry up all the water left behind, and install the new one. You do have to make sure it's clocked right so that it will correctly regulate the water temperature. What I did was take a picture of the old one before I took it out so I could install the new one the exact same way. Worked great and the leak was gone once installed. Super easy to install!

I had a dripping shower head in my master bathroom. I wasn't able to see the Kohler name on the plate, and couldn't find any set screws to remove it from the wall. I ended up calling a plumber, assuming that I just needed to try to unscrew it from the wall and change a cartridge, but not wanting to break anything or have a water leak in the wall. The plumber said, I think it's a Kohler, and if that is the case, you don't want us to change it for you. The reason being....they charge $516 to change this particular cartridge. He said, you can easily change this on your own, you simply remove the 4 screws, pull it out, put the new one in, and tighten the screws. I ordered the part from Amazon for $47 and changed it myself in about 8 minutes. This replacement couldn't have been easier.

I bought this shower cartridge for my Kohler setup, and it worked perfectly. The fit was right, the installation was straightforward, and it solved the issue without any extra hassle. It’s a single-piece design, which made the whole process much easier than I expected. If you have the same compatible Kohler model, this is a simple and reliable replacement that gets the job done.

Perfect replacement

Never buy a Kohler product that uses this valve. This is my first and last Kohler purchase. I had to replace a broken showerhead, and on my plumber’s recommendation I went with Kohler, since he said it would be easy to service and find parts for. That turned out to be a huge mistake. Within less than two years, the valve started dripping. I bought a replacement, and within six months it also began dripping. Even worse, the dripping is inconsistent — some days it drips, some days it doesn’t. The most annoying issue is with the hot water. When I turn the handle fully to hot, the faucet never delivers truly hot water (and yes, I already adjusted the safety limit to maximum). Strangely, the showerhead produces hotter water than the faucet, which makes me think the valve is defective and still mixing in cold water even when set to hot. As a result, if I want to fill my tub with hot water, I have to use my other shower, which has a Grohe showerhead. Run away from this product if you can. Unfortunately, if you’re already looking for this valve, you’re stuck with it unless you replace the entire shower system. For me, if this fails again, I’ll rip everything out and replace it completely. What a waste of time and money. I feel insulted by this company.

This genuine KOHLER Rite-Temp cartridge (GP800881) was a breeze to install. The one-piece design really does simplify the process, making it a quick DIY job. It works perfectly and my shower head no longer drips water. My only complaint is that my previous official Kohler cartridge only lasted about three years, which seems a bit short for a premium part given the price point. I'm hoping this one has better longevity because the installation and performance are excellent.

Easy to change out (once I saw the plumber do it). Unfortunately, this model by Kohler was not their better product. More importantly this item doesn't last but 4 or 5 years.

"I recently had to replace the pressure balance cartridge in my Kohler shower valve, and after doing some research, I decided to go with the Kohler Genuine Part GP800881. As I’ve had great experiences with Kohler products in the past, I trusted this replacement part to restore my shower to its optimal performance." Overall, I’m very satisfied with the Kohler GP800881 Pressure Balance Cartridge. It has restored my shower’s functionality and provided the consistent water temperature and pressure I was looking for. If you have a Kohler shower system and need a reliable replacement part, I highly recommend this cartridge. It’s a great investment in both quality and long-term performance."
