Grohe 45882000 Ceramic cartridge, No Finish

Love it. Works great. Expensive though.

Easy to install and works perfectly

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.

Just installed it. Seems to have a good quality. This cartridge is for the hot side. Opens counter clockwise. I believe that’s the reason on the Grohe website it is referred to as “Right” side. Hope that helps

When we had our house built, I went a little crazy and picked Grohe fixtures for the entire house. I liked the design and thought that they would be top quality. Over time, even these expensive faucets developed leaks. The replacement cartridges proved very expensive (list price is nearly $50!!!) and the real problem is that changing them is rather difficult. Changing this valve, I had to take the sink completely out of the vanity because the cartridge was so corroded into the base of the faucet. Having changed a few of these now, I discovered that this is a common fault on each and way too much work for such a routine task. If I could go back in time and opt for more conventional faucets, I would do so. Grohe may be cool but it is typical of a lot of German design - overly complex and darn expensive. If you need a replacement cartridge, make sure you get the right one (right close vs left close) and when you install it, use pipe tape on the thread to make sure that you can easily replace the cartridge years down the road.

Perfect. Repaired my shower.

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.
