How To Adjust Temperature On Kohler Shower Valve [Step-by-step Guide]

Adjusting the temperature of a Kohler shower valve is a relatively straightforward process, which you can complete with just a few simple steps. But here is one thing to keep in note the Kohler shower valve temperature adjustment procedures will vary depending on the specific model of the Kohler brand.

But don’t get yourself in trouble! Here I am with you till the end bringing a comprehensive guide, outlining all the needed processes to adjust the Kohler shower temperature, no matter which valve you have equipped. 

So, without getting late, let’s dive right in with me till the end. 

Step 1: Gather The Essential Tools

As for the step, you will have to manage the essential tools to adjust the temperature. For instance, you typically won’t need many specialized tools. Here are the list of some basic tools you will need: 

• A large pliers 
• A thermometer 
• Allen wrench (hex key) 
• A Phillips head screwdriver
• A large flat-blade screwdriver 

For safety purposes you will need the:

• Safety Gloves
• Safety goggles or glasses
• Towels or rags to protect the shower floor from any water splashes
• User Manual or Documentation for better guidelines

Step 2: Turn Off The Water Supply

Before attempting any adjustment process, it is essential to turn off the water supply to your shower. For instance, locate the main water shutoff valve of your home near your water meter or in a utility room.

Turn the valve meter to the off position to prevent any potential accidents or water damage.

Step 3: Remove The Shower Handle

As for the first step, you will have to remove the shower handle to access the valve assembly. You will find the handle secured with a set screw or held in place with a cover plate that can be gently pried off. 

Take a flathead screwdriver and pry off the cover plate or cap to access the handle screw. Now,  unscrew the screw on the valve stem using a Philips screwdriver, and then remove the handle and faucet faceplate.

While doing so, take care not to damage the fixtures or surrounding tiles.

Step 4: Determine The Valve Type

After removing the shower handle and faceplate, now you will have full access to the valve assembly. Before heading over to the temperature adjustment, determine the valve type you have. 

Typically, Kohler shower valves can have different types of controls, such as single-handle or dual-handle valves.

Step 5: Adjust the Temperature

Here I’m providing the needed steps to adjust the temperature on both single-handle or dual-handle shower valves. 

#For Single-Handle Valves:

If you have a single-handle valve, typically, you’ll have one handle to adjust hot or cold water. But before that, remove the O-ring and collar from the valve stem. When done, slowly rotate the valve stem clockwise or counterclockwise and adjust the temperature to your desired setting. 

Once you have done this, reinstall the collar on the valve stem with the setscrew and secure the O-ring back in place. 

#For Two-Handle Valves:

If you have two handles on your Kohler shower, you will get two handles to adjust the water temperature. One handle controls hot water, and the other controls cold water.

Begin by turning the hot water handle counterclockwise to the desired temperature. Gradually turn the cold water handle clockwise until you achieve the desired mix of hot and cold water. Fine-tune the temperature by making slight adjustments to both handles as needed.

Step 6: Adjust The Temperature On the Kohler Rite-Temp shower valve

If you have a Kohler Rite-Temp shower valve, then the temperature adjustment process will be a bit different. In general, the Rite-Temp valve on the Kohler shower is designed to provide reliable and consistent water temperature and pressure in showers. 

It is one type of pressure-balancing valve that typically helps prevent sudden temperature fluctuations. It works by maintaining a balance between hot and cold water pressures.

To adjust the temperature in a pressure-balancing valve, here are the simple steps to follow:

• First up, look for the temperature adjustment knob or lever on the valve body. This control is usually located near the center or on the side of the valve.
• Now, simply rotate the knob clockwise to decrease the temperature or counterclockwise to increase it.

• In case you find the valve with a lever, simply move it towards the hot side to increase the temperature or towards the cold side to decrease it.

Step 7: Adjust The Kohler Thermostatic Mixing Valve

The thermostatic mixing valve is another temperature control mechanism of the Kohler shower that is responsible for mixing hot and cold water to achieve the desired temperature.

Typically, for thermostatic shower valves, adjusting the temperature typically involves modifying the position of the thermostatic cartridge. 

To adjust the thermostatic cartridge:

• Locate the temperature stop device on the cartridge. This stop is usually a plastic piece that limits how far the handle can rotate towards the hot water side. By repositioning this stop, you can change the maximum temperature of the shower.

• Using an Allen wrench or a suitable tool, loosen the set screw holding the temperature stop in place. 

• Rotate the stop clockwise to decrease the maximum temperature or counterclockwise to increase it. 

• Make small adjustments, testing the water temperature after each one until you achieve the desired result.

Step 8: Test The Water Temperature

Once you have done the temperature adjustment, this is the most crucial part you must have to follow. With the minor adjustment. You will need to test the water. Use a thermometer in this instance. 

Ensure to keep the temperature at a safer level of no more than 120 degrees Fahrenheit. If you are exceeding this safety level, any individual in your house can be burned in one second. 

Also, avoid setting the temperature too low as lower temperatures foster the growth of unhealthy bacteria in the water. 

Besides, higher temperature kills bacteria but increases the chances of scalding. Thus it is better to set the water temperature to 120 degrees Fahrenheit

Step 9: Reassemble And Test

Once you’ve made the necessary adjustments to the temperature control mechanism, carefully reassemble the shower valve by attaching the handle and escutcheon plate. 

Ensure that all screws or fasteners are tightened securely but not excessively, as overtightening can cause damage. After reassembling the valve, turn the main water supply back on and test the shower. 

Then, gradually adjust the handle or lever to your desired temperature and verify that the water flows at the correct temperature. Pay attention to any unusual noises or leaks, which may indicate a problem that requires further attention.

Step 10: Repeat If Necessary

If the water temperature is still not to your liking, repeat the adjustment process until you achieve the desired temperature.

Step 11: Consider Consulting The User Manual

 If you have difficulty locating or adjusting the temperature control on your specific Kohler shower valve, refer to the user manual or contact Kohler customer support for further assistance.
