How to Change the Temperature Setting of a Kohler Shower

Quck answer

To adjust a Kohler shower temperature regulator, follow these steps:

1. Locate the temperature regulator: It is usually located behind the temperature control handle or inside the shower valve.

2. Remove the temperature control handle: Use a screwdriver or Allen wrench to remove the handle, depending on the type of handle used.

3. Adjust the temperature regulator: Use a wrench to turn the temperature regulator counterclockwise to increase the temperature or clockwise to decrease it.

4. Test the water temperature: Turn on the shower and check if the water temperature is now at the desired level.

5. Reassemble the handle: Once the temperature is adjusted, put the handle back in place and tighten it securely.

Remember to be cautious when adjusting the temperature regulator to avoid scalding or freezing water temperatures.


Kohler showers are equipped with a temperature regulator that prevents scalding or discomfort during use. This regulator acts as a stopper, limiting the shower handle from being turned beyond a certain temperature. If you find that you want a warmer or cooler water temperature, you can easily adjust the temperature regulator.

Getting Ready for Adjustments

The accuracy of the regulator’s temperature depends on your water heater, and it may become inaccurate if the water heater has been recently replaced or adjusted. Whether you want the water to be warmer or cooler, you can access and change the temperature regulator on Kohler showers using basic tools.

The specific steps may vary depending on your model. If possible, refer to your user manual or find it online and follow the instructions for your specific shower. In most cases, accessing the temperature regulator will follow a similar process. If you cannot find a manual for your model, try these general steps.

Removing the Handle and Faceplate

The first step in adjusting the temperature regulator is to remove the shower handle. Look for a screw that connects the handle to the faceplate (usually located under the curve of lever handles) and remove it with a screwdriver or an Allen wrench if necessary. Keep track of each piece and set them aside. Remove the handle from the faucet to better access the faceplate.

If there are any adapters, inserts, or sleeves attached to the faceplate, remove them as well. Keep track of all hardware for easier reinstallation.

Using a screwdriver, remove the remaining screws on the faceplate. These screws may be visible on the front or hidden along the side. Set them aside and remove the faceplate from the wall. You will now have access to the temperature regulator.

Adjusting the Temperature Regulator

Locate the valve stem and collar on the temperature regulator. These are the parts that would connect to and turn the handle if it were still attached. Turn the valve stem and collar clockwise to initiate the flow of hot water. Be cautious of hot water splashing. Check the temperature with a thermometer. It should not exceed 120 degrees Fahrenheit.

Turn the set-screw on the collar counterclockwise to increase the maximum temperature of your shower. To decrease the maximum temperature, turn the set-screw clockwise. Once you have found your preferred temperature, check it with a thermometer to ensure it is safe, and adjust the collar to stop the stem in the right position. Then, turn off the water.

Depending on the Kohler model, you may need to remove the O-ring, caution tag, and collar for the adjustments. The O-ring is a small ring around the stem, the caution tag is located below it, and the collar is a red (sometimes black) ring beneath the first two parts. Set these aside, rotate the valve stem as described above, and then reattach the collar to the appropriate setting. Turn off the water and reassemble the shower.

Putting the Handle and Faceplate Back Together

If you took apart your faucet with caution, putting it back together should be relatively simple. Follow the order in which you arranged the pieces and screw the faceplate back onto the wall. After that, secure all the other parts.

Then, reattach the handle. Finally, turn on the shower to verify that it was reassembled correctly and that the water temperature is comfortable as desired. Remember, if necessary, you can also make adjustments at the water heater.
