Question about Grohe Grohmix Thermostat Valve & Trim - 34436

1 Answer

My grohe shower thermostat is set too hot. How can I adjust the valve to allow more cold water? I don't have a manual and don't know the model number. It is a high end unit - flat face plate on the wall with large round temperature controller in the middle. Face plate has two screws, which I removed and I was able to look behind the plate but wasn't able to remove because I'm unable to remove the large round controller in the middle. Thanks for your help.

    Thanks. I went to the Grohe site a few minutes ago. Our shower is approx 5 years old. The current model that appears to be the closest match 19 229. The only difference is that our face plate is flat and rectangular. The valve head is very similar. Can I just pull the head off? I am afraid to pull too hard and have not been able to get it off. Is there a screw or button that I need to push to get the head off?

    Thanks for your help. The usual temperature readjustment for the thermostat numbers was not enough. I think took the green adjuster out of the unit, but was unable to get it back on with the washer attached. Without the washer it fit back on - without it did not. I tried to force it back on with the washer, and it broke since it is plastic. Will have to figure out from here whether I can find the plastic or will need to get an entire kit. Thanks again.

This should help you with setting the hot water on your valve.


Maximum hot water limit setting

The adjustable hot water limit stop (F) is factory set in a neutral

position (0), see fig. [5].

On applications requiring to limit the valve opening from full hot

position, the factory set adjustable hot water limit stop must be

reset as described below.

1. Remove the factory set adjustable hot water limit stop (F),

see fig. [6].

2. Slide the adapter (G) onto the valve stem (B) by placing the

stop post (G1) on top of "Arrow" ? (H), see fig. [5] and foldout

page III, fig. [7].

3. Turn the adapter (G) counterclockwise until the outlet water

reaches the desired temperature and read the corresponding

number (1 to 10, see fig. [5]) against the stop post (G1).

4. Close the valve by turning the adapter (G) clockwise and

remove the adapter (G).

5. Align the white mark (F1) on the limit stop (F) against the

number (1 to 10, see fig. [5]) you have selected on the dial

and slide the limit stop (F), see fig. [8].

6. Proceed to item 6 in chapter "Installation" to install the
lever (N).

    2.Remove thermostat handle cap (47 428) and

    decorative ring complete (47 429) or lever

    3.Take out fixing ring (M), see fig. [5].

    4.Pull off thermostat handle (N).

    5.Pull sleeve (F) from the mixer shank by pressing

    down the tongue (R), see fig. [6].

    6. Extract clamp (E).

    7.Pull stop ring (D) until resistance is encountered

    (approximately 3/8" [10mm]), see fig. [7].

The temperature in my shower is very luke warm only at the shower


Do you mean the other faucets in the house are hot and only the shower is warm? If so there is an anti-scald adjustment on the faucet that needs to be turned up a few notches. Havent adjusted a Grohe faucet but most faucets you rmove the handle and behind the handle is a nothced adjustment ring that prevents the faucet from getting too hot. This ring, or stop, is pulled out and twisted clockwise(or counter clockwise to set higher or lower max temp, then pushed back. maybe you can look up grohe to see which way ring or stop adjusts for hotter water.

Grohe shower. I want to adjust the temp mixing valve. I can not get cold water. It is always a mix-never pure cold. I want cold water. How do I adjust it?


if you pull the handle off all the way back to the valve body there is a little black stopper around the cartridge body that you can adjust by pulling it out and sliding around the cartridge body this enables people to just turn the handle to one setting and jumpping in to their favorite temperature. in your case it doesn't allow you to have any cold water. so turn it one way see if you get what you want or try the other or some of them you can even just take the darn thing out and not even have to worry about it

you need to change the cartridge, it is a temp control and is going bad so it keeps you from burning yourself it is like a mixing valve and is givng more cold water, that way you don;t get burned,,
