Step 1
⏱ 2 min
Turn Off the Water Supply
Before starting any repairs, safety first! Turn off the water supply to the shower. Locate the shut-off valves—usually under the sink or in the basement. If you don't have shut-off valves, turn off your home's main water supply. Remember to always double-check that the water is completely off before proceeding.
Step 2
⏱ 2 min
Remove the Shower Handle(s)
Carefully remove the handle(s). Two-handle faucets usually have a screw beneath each handle cap. Use a screwdriver (or Allen wrench) to remove these screws and then gently pull off the handles. If they're stuck, a handle puller might be necessary. Take photos before disassembling to help with reassembly.
Step 3
⏱ 2 min
