47582000 Thermostatic Cartridge, 3/4", StarLight Chrome

Simple fix but you need some big wrenches to get the old one out.

This fixed our leaking shower. A great product.

Needed a new cartridge as the shower was not delivering hot water any longer. Grohe customer service assured me this was the correct cartridge although it did not look like the installed one. They said it had had a redesign in the intervening years. Received it, installed it and now our shower is delivering hot water.

Pretty pricy for a shower cartridge, but necessary when it no longer delivers the temp you set. Needed a 15/16 deep well socket to remove the old one.

Replaced my 20+ year old Grohe 47310 cartridge. The 47582 looks different/new design, very expensive... but it works!!!

Our shower started to produce only one lukewarm temperature, which definitely wasn't desired. This has the same part number as what I pulled out of the valve, but it has definitely been redesigned. See the included image for what the old design for this part looks like. It does come with a tiny packet of lubricant, enough to do the o-rings on the cartridge and on the outer housing of the valve if you're judicious. No real issues with it, fairly easy to calibrate (even if the numbers in an absolute sense are rather arbitrary). My biggest gripe with this thing is how much it costs, hardly seems like this should be $200.

Fit just right corrected problem. Like to have seen is updated cartridge and replaced the earlier version. It looked different and had to research to find it was for valve I had

new replacement design works perfectly at installation. trying to use paraffin cartridge anti-scald in combination with extremely cold water and tankless water heaters is a challenge! let's see if this new design makes it a little easier.
