- Turn off the water supply to the shower. You may find the shut-off valves behind the shower wall in the room adjacent to the shower or a closet, or you may have to turn off water at the main house shut-off valve. Turn the shut-off valves counterclockwise.
- Place the bathtub stopper in the down position to prevent accidentally dropping the knob-securing screws down the drain.
- Find the securing screw on the side of the handle, if you have lever-type handles. Remove the screw with either a Phillips-head screwdriver or Allen wrench, depending on the type of screw head. Pull the handle straight off the plumbing.
- Pry the plastic cap on top of the shower knob, if your shower uses cylindrical knobs. There will be a small notch between the cover and the handle in which you can fit a small flat-head screwdriver to pry the cover off the knob.
- Turn the screw in the center of the shower knob counterclockwise with a Phillips-head screwdriver. Pull the shower knob straight off the plumbing.
How to Take Knobs Off of a Shower
When repairing a leaky shower knob or replacing the knob for a new look, you will need to take the knobs off the shower fixtures. The knobs on a shower will either be cylindrical knobs or lever handles. The knobs secure to the faucet plumbing with screws. Some lever handles may have a small rubber cap covering the screw head, and cylindrical knobs usually have a decorative cover hiding the retaining screw.
