Grohe 45882000 Ceramic cartridge, No Finish

This worked perfect for a very hard to find part

Great price and fast delivery. Genuine part. Can't beat it

I ordered this ceramic cartridge to stop the drip on my 12 year old GROHE 20086 Atrio basin pillar/tap (faucet). The faucet is a legacy/discontinued/obsolete product and it was difficult to find information on the internet. I finally did find information in a specification sheet from GROHE, indicating this cartridge 1/2 inch R, 45 882 000 was the correct cartridge. It would seem that Grohe makes this cartridge in two different types, one for a hot water (or hot water side) and another for cold water. This one was in fact for the hot water which is what I needed. It turns out that in my case the handle of my faucet just pulls or taps off as there are no fasteners of any kind to hold it on. I did remember to turn off the water supply under the sink. Once the handle was off there was a straight slot screw to remove along with a white plastic gear. Once they were out of the way I could see the old leaky cartridge; it took a 17 mm socket and wrench to remove the old cartridge. The new cartridge was identical and I began by threading it by hand and then tightened it with the socket wrench. I did use a flashlight to assure there was no debris and cleaned up the filmy accumulations of soils. Once it was all put back together and the water supply turned back on, there was no longer any drip. This faucet is one where it only takes 1/4 turn of the handle to turn the water off and on. The new cartridge box indicates it is made in Germany which is where Grohe fixtures are made. If this one lasts for 12 years like the first one, I'll be happy. The pic is of my Grohe faucet; your faucet may have a different handle, finish or even be from a different Grohe line. I paid $24.99 for this cartridge on Amazon which was far and away the best deal I could find.

It fit exactly like it was supposed to. After turning the water off to the house it took about 5 min start to finish with a 17mm deep socket. The 90 degree turn is nice, feels well built.

I've only a couple complaints about the part itself: 1) It took a long time to deliver. I assume that is because availability is very limited (two previous orders with other sellers were outright cancelled.) 2) I feel the price is a bit high.Because of the build up of calcium, the old part was really hard to remove but of course that is no fault of this replacement. This installed relatively very easily and works like new. Sure beats having to replace the whole faucet assembly.

We have three Grohe faucets that are 18 years old and after much research with Grohe found that we could get the replacement parts from Amazon and were thrilled. Otherwise, we would have had to buy all new fixtures at several hundreds of dollars. The parts were reasonably priced and came in two shipments. We were able to have our plumber install them in a few short minutes. Amazon is amazing!

Does exactly what it's supposed to do... easy to install once you figure out the trick (I had to put a chunk of 2x4 to block movement of the fitting below the countertop when loosening/tightening the cartridge from the top). The box and product are *marked* made in Germany, but that's no guarantee these day. Either way, the price was right and it works great.Note: this part number shuts off the water when you rotate it clockwise, which is great for a hot-water handle but incorrect for a cold-water handle.

Works as it should.
