How to Repair a Leaking Kohler Shower Faucet

If you can't stand that leaking Kohler shower faucet anymore, don't worry, it takes just about 20 minutes to fix. As long as you have the right Kohler replacement part, this project is something anyone with the most basic skills can master. The problem with the faucet is the cartridge, the valve inside the faucet's body. Carefully remove and replace this part with a new Kohler cartridge, and your faucet will work just like new.

Step 1

Shut the main water line in the home, which is usually by the water heater.

Step 2

Find the set screw that secures the handle to the cartridge stem. On most Kohler models it is underneath the handle's lever. Unscrew this screw with an Allen wrench and pull back on the handle to remove it.

Step 3

Remove the adapter, if there is one, on the stem by unscrewing the adapter's screw with a screwdriver and sliding the adapter off of the faucet.

Step 4

Remove the trim plate by unscrewing the trim plate's screws and lifting it off of the shower wall. Unscrew the two screws in the cartridge collar, the housing holding your faucet cartridge, with a screwdriver and take the collar out of the faucet. The collar contains the cartridge.

Step 5

Replace the collar with a new part from Kohler and tighten the collar screws. Replace the trim plate and tighten the trim plate screws. Replace the adapter and handle, and tighten the handle's set screw.
