I have a Grohe Shower mixing body installed about 13 years ago. I think it is a Grohetep or something like that.
It has a top shower head and two side heads in a stand up shower with separate knobs to turn each on and off. The shower runs scalding hot now with no change in temperature when I turn the temperature control know in the center. I looked online for a temperature valve replacement and first the body is discontinued and secondly the thermo valve is ridiculously expensive. I am not even sure if I replace it, it will fix the problem. I am now interested in replacing the entire body. Any suggestions as to which body will work best with this set up. I am not interested in precise temperature adjustment. Just old fashion mixing. Thanks for your help.

why not contact grohe to see if they will give you what you need for free. it is called a lifetime guarantee

Hi All,

We only wish Grohe has a lifetime warranty.

Electronic Faucets, Valves and Controls Warranty: GROHE warrants its electronic faucets, valves and controls to be free from manufacturing defects in material and workmanship under normal use for five (5) years from the date of purchase.

symmons temptrol valves are a good valve and very reasonably priced.
big box stores carry them.

I didn't see anywhere that you stated it was an "electronic faucet". I got the impression it was a shower panel mounted outside the wall.

Thanks for the advice. That works fine for me.
