Replace a Broken Shower Head (No Plumber Needed)

The most common mistake: over-tightening with a wrench and cracking the new head — hand-tight plus one quarter-turn is all you need. This is a 10-minute job requiring zero plumbing experience.

Step 1 — Remove the Old Shower Head

1. Turn off the water at the shower valve (no need to shut off the main).
2. Wrap a cloth around the shower arm (the pipe sticking out of the wall) to protect the finish.
3. Use an adjustable wrench or slip-joint pliers to grip the hex nut at the base of the old shower head and turn counter-clockwise.
4. If it is stuck, spray penetrating oil at the joint and wait 10 minutes before trying again.

Step 2 — Prep the Threads

1. Once removed, inspect the shower arm threads for damage or old tape/debris.
2. Clean the threads with an old toothbrush.
3. Wrap plumber's tape (Teflon tape) clockwise around the threads 2-3 times — this is the single most important step for preventing leaks.

Step 3 — Install the New Shower Head

1. Hand-thread the new shower head onto the arm clockwise until snug.
2. Use a wrench for one additional quarter-turn only — never over-tighten.
3. Turn the water on and check for leaks at the connection point. If it drips, add one more quarter-turn.

Choosing the Right Replacement

• Standard fixed head: cheapest, $15–50 CAD, always fits (all North American showers use ½-inch NPT threads).
• Handheld with hose: best for bathing kids/pets and cleaning the tub.
• Rain shower head: wide ceiling-style spray — check your water pressure first (needs 40+ PSI or flow feels weak).
• Low-flow (2.0 GPM or less): saves money on water bills and is recommended if you are on a well or have low pressure.

Pro tip: If the shower arm itself is corroded or wobbles in the wall, replace it at the same time — they cost $8–15 and thread directly into the elbow in the wall. Ignoring a wobbly arm can eventually crack the fitting inside the wall, turning a $20 fix into a $500 plumber call.
