How to Install a New Shower Head

SHOWER HEADS are the single most effective way to upgrade a bathroom's functionality without touching the plumbing behind the wall. Over time, mineral deposits clog the nozzles and reduce pressure, making a simple swap feel like a complete renovation. When you choose a new fixture, you aren't just changing the look of your shower; you are reclaiming control over your morning routine. Installing a new unit requires only a few minutes and a basic tool. The key to a drip-free installation lies entirely in the preparation of the threaded arm extending from the wall. By clearing out old debris and properly applying sealant tape, you ensure that the connection remains tight and leak-free for years to come.

Unscrew the Old Unit. Wrap a cloth around the base of the shower arm to protect the finish, then use a wrench to turn the old shower head counter-clockwise. Once the head is loose, unscrew it by hand the rest of the way.
Clear Out Mineral Buildup. Use a stiff-bristled brush or a clean rag to scrub away any old plumber's tape or mineral buildup from the threads on the wall-mounted shower arm. The threads should be smooth and free of debris to allow the new head to seat properly.
Seal the Threads. Wrap white plumber's tape (PTFE tape) around the threads of the shower arm in a clockwise direction. Apply 3 to 4 wraps, pressing the tape firmly into the grooves of the threads as you go.
Screw On By Hand. Hand-tighten the new shower head onto the arm by turning it clockwise. Ensure the threads catch smoothly and do not force it if you feel resistance.
Fine-Tune the Fit. If the head is not quite tight after hand-turning, use a wrench with a cloth buffer to give it an extra quarter-turn. Do not overtighten, as this can snap the shower arm off inside the wall.
Verify It's Leak-Free. Turn on the water and let it run for a minute to check for any dripping at the connection point. If you see water spraying from the threads, turn off the water, unscrew the head, and apply more tape.
