Kohler K-GP77006-RP GP77006-rp Ceramic Valve, One Size, Rough Plate

The valve on our bath became stuck on about a year and a half ago. I panicked and broke the handle and was able to get the water off. I didnt have the knowledge to fix it myself at the time or the funds to hire someone, so the tub sat since then. I finally watched some YouTube videos for tub repair and took on the task of fixing the tub myself. Once all the parts came in, it only took about a total of an hour labor tops, and just over $100 to make the repairs myself.

Perfect replacement. Works great!

I had great success installing the hot ceramic cartridge in my 15 year old bath faucet. It works perfectly. My cold ceramic cartridge is standing by for when needed. I purchased both through Amazon prime. The price was good and the delivery was quick and super convenient. No trips to the hardware store for me.

These are no fun to change if they are stuck together. They fit the faucet and work fine . I had to completely remove the faucet / mount in a soft jawed vice /penetrating oil/ propane torch. Get the picture . If yours dont come apart easily , you may save time and frustration by purchasing a new faucet.

Works great.

I have no choice but to keep replacing. Due to hard water in my area (CA), this valve will seize and stop turning in a few years. My faucet is too expensive to replace. It is cheap enough to replace the cartridge once in a few years.

Perfect fit

Did just what I needed it to do, and easy to install.

I originally ordered GP1092203 and that is for the same faucet, but a newer revision. If you have the older version then you will need this all brass and copper valve (the good old quality Kohler) otherwise the newer part number is largely plastic and wont even be close to fitting. Unfortunately the only way I know how to tell the difference is disassemble the faucet before ordering the replacement part.

Fit fine but the old one was made with Brass and copper. This appears to be chromed steel or maybe stainless. I replaced the hard to turn unit with this, then soaked the old unit in vinegar overnight before disassembling, soaking parts in vinegar again to get the calcium out of the insides. Lubed with pool lube and re-assembled. Ill keep it on-hand to replace the next one that gets too difficult to turn. To rebuild, remove the clip and bow-tie stopper from the top, pull the washer off the bottom, and push the top down through the base. But unless you have extra time to do this, its cheap enough to just buy a new one next time. Use Teflon tape when replacing to make it much easier to take out next time. As others have noted, it really doesnt matter which side you buy. The only difference between hot and cold is a little bow-tie stopper on the top held in place with a clip. If you want to switch it, pull the clip and rotate the stopper 90 degrees. Pictures are of the old one rebuilt to show the clip and stopper.
