Most often, your Kohler shower head will be leaking due to a faulty seal. This faulty seal can be fixed by purchasing new plumber's tape and a new washer. Remove the shower head and check the connector to the shower arm and to the hose (if you have a handheld shower unit). Then, replace the washer in each connector hole with a new washer. Take your plumber’s tape and place it over the threads on the shower arm as well as the other connector spots. Remove the old plumber’s tape first. Then screw each component back together for a tight seal, free of leaks.
