What You’ll Need
- Adjustable wrench
- Plumber’s tape (PTFE tape, 1/2-inch standard width)
- Bucket or rag
- New showerhead (standard 1/2-inch NPT connection)
- Silicone lubricant spray (optional, for stubborn fittings)
Steps
- Remove the old showerhead. Turn it counterclockwise by hand. Hold the shower arm steady with your other hand so you don’t twist the pipe inside the wall. If it’s stuck, wrap your wrench jaws with masking tape and grip the hex nut behind the showerhead. I’ve swapped three showerheads in my house, and the first one took me five minutes just to get unstuck — a little patience here goes a long way.
- Clean the threads on the shower arm. Use a rag to wipe off old tape, dried sealant, and mineral buildup from the exposed pipe threads. A clean surface helps the new tape seal properly.
- Wrap plumber’s tape around the threads. Hold the tape against the end of the threads and wrap it clockwise 5 or 6 times. Keep it tight and smooth. Leave the first thread uncovered so tape doesn’t flake into the water line.
- Attach the new showerhead. Thread it onto the shower arm by hand, turning clockwise. Go slowly so the threads engage smoothly. Keep going until it’s hand-tight and snug.
- Tighten gently with a wrench. Give the hex nut one final quarter turn with the wrench. Stop as soon as you feel resistance. Overtightening can crack the showerhead or strip the threads.
- Turn the water on and test for leaks. Open the shower valve all the way. Check the connection where the showerhead meets the arm. Tighten another eighth turn if you see drips. If water sprays from the arm itself, call a plumber — the fitting inside the wall may be damaged.
Pro Tips
Tip: Run hot water through the new showerhead for 30 seconds before your first real shower. This flushes out any metal shavings or debris left from manufacturing.
Caution: Always hold the shower arm with one hand while loosening or tightening the showerhead. The shower arm connects inside the wall with a soldered or compression fitting. Twisting the arm without bracing it can break that fitting and cause a leak behind the tiles — a repair far more expensive than a new showerhead.
