How to Fix a Leaking Shower Head: Causes, Repairs and Costs

You step out of the shower and turn the handle all the way off and the shower head keeps going. Drip and drip and drip. Or maybe water sprays from the joint where the head meets the pipe and runs down your arm. A leaking shower head wastes water and stains tile and keeps you wondering what is going wrong behind the wall. The reassuring part is that most leaks come from a few cheap parts that you can fix in about fifteen minutes.

This guide explains how to fix a leaking shower head and how to tell where the water is really coming from. You will see the common causes and the exact repair for each one including leaks at the base and the swivel and the wall. You will also learn why a shower head drips when it is off and when the problem is the valve and not the head and what a plumber charges if you decide to hire one.

Why Is My Shower Head Leaking?

A shower head is simple. Water travels up the shower arm and through the head and out the spray holes. A leak means water is escaping somewhere along that path or the valve behind the wall is not shutting off fully. The most common causes are:

Worn thread tape. The thin plumber’s tape wrapped around the threads of the shower arm breaks down over time and lets water seep out at the connection.
Mineral buildup. Hard water leaves scale on the spray holes and inside the head. Blocked holes force water out through gaps at the faceplate or the joint.
A worn washer or O-ring. The rubber seal inside the head dries out or splits and no longer holds a tight seal.
A loose or misaligned connection. The head may simply not be tight enough or it may have been cross threaded when it was installed.
A failing cartridge or valve. If the water drips from the head even though the shower is off the problem is usually behind the wall and not in the head at all.
High water pressure. Pressure well above normal stresses every joint and seal in the shower.

The trick is working out which one you have before you start unscrewing things. The next section shows you how.

Where Is the Shower Head Leaking From?

The spot where the water appears tells you most of what you need to know. Check these places with the shower running and then with it off.

Shower Head Leaking at the Connection

If water drips or sprays from the joint where the shower head screws onto the shower arm the cause is almost always worn tape or a missing or damaged washer. This is the easiest leak to fix and also the most common.

Shower Head Leaking at the Base or Swivel

Many shower heads have a ball joint that lets you tilt the head. Water that leaks from that joint points to a worn O-ring or a collar that has come loose. Heads with a swivel are more likely to leak here than fixed ones.

Shower Head Leaking From the Faceplate or Spray Holes

Water running out from the edge of the faceplate or from the top of the head usually means mineral buildup has clogged the holes. The water cannot exit the nozzles so it finds the path of least resistance.

Shower Head Leaking at the Wall

If the water appears where the shower arm meets the wall the problem is behind the head. The arm may be loose in the wall or the threaded fitting behind the tile may be failing. This one often needs a plumber.

Shower Head Dripping When the Water Is Off

A steady drip that continues after the shower is off is different from the normal trickle that lasts a minute or two. A small amount of water is always trapped in the head and arm and drains out slowly after you shut the water off. That is normal. A drip that goes on for several minutes or all day means a worn cartridge or valve is letting water through.

How to Fix a Leaking Shower Head

Start with the cheap and easy repairs. Most shower head leaks are solved in the first few steps.

Tools and Materials

You do not need much:

Plumber’s tape (also called Teflon tape)
An adjustable wrench or pliers
A soft cloth or rag
White vinegar and a plastic bag and a rubber band
An old toothbrush or a small nylon brush
A replacement washer or O-ring if the old one is damaged

Step 1: Check That the Head Is Tight

Sometimes the fix is as simple as a quarter turn. Hold the shower arm steady with one hand and tighten the head by hand. If it still leaks move on. Do not crank it down with a wrench since overtightening can crack plastic parts and the arm.

Step 2: Remove the Shower Head

Turn the head counterclockwise to unscrew it from the arm. Wrap a cloth around the head before you use pliers or a wrench so you do not scratch the finish. Hold the arm with your other hand so it does not turn inside the wall. If the head will not budge a bit of penetrating oil on the threads can help but wipe it all off afterward.

Step 3: Replace the Plumber’s Tape

Peel off all the old tape from the threads of the shower arm. Wipe the threads clean. Wrap fresh tape around the threads three or four times in the clockwise direction as you look at the end of the arm. This is the direction the head tightens so the tape stays put when you screw the head back on.

Step 4: Inspect the Washer

Look inside the connection on the shower head. You should see a small rubber washer or a flat gasket. If it is cracked or flattened or missing replace it. Take the old one to the hardware store to match the size. A common mistake on a new shower head is leaving two washers stacked or forgetting the washer entirely so check that there is exactly one.

Step 5: Clean Out Mineral Buildup

Scale is a hidden cause of leaks. To clean it:

Fill a plastic bag with white vinegar and slip it over the shower head so the head sits in the liquid. Secure it with a rubber band.
Leave it for several hours or overnight for heavy buildup.
Remove the bag and scrub the spray nozzles with an old toothbrush. Run water through the head to flush loose deposits.

Check your manufacturer’s instructions first. Vinegar can dull some finishes such as brass and oil rubbed bronze and polished nickel so soak those for a much shorter time or use a milder cleaner.

Step 6: Reattach and Test

Screw the head back onto the arm by hand and then give it a gentle quarter turn with a wrench wrapped in cloth. Turn the water on and watch the connection. If it stays dry you are done. If it still leaks move on to the next fixes.

How to Fix a Leaking Shower Head at the Swivel or Ball Joint

For a head that leaks from the tilt joint you usually need to open it up. Unscrew the collar that holds the ball joint and take it apart carefully. Look for a worn rubber O-ring or washer inside. Replace it with an exact match and put a small amount of silicone plumber’s grease on it before you reassemble. If the plastic is cracked a new head costs less than the hassle of hunting for parts.

How to Fix a Handheld Shower Head Leaking

A handheld shower head has two places to leak. The first is where the hose attaches to the shower arm or the wall bracket. The second is where the hose connects to the handheld head.

At the hose connections: Check the small rubber washers inside each connector. Replace them if they are flat or cracked.
Along the hose: Look for cracks or bulges. A damaged hose cannot be repaired and must be replaced.
At the head: Tighten the connection by hand and replace the washer if needed.

How to Fix a Leaking Rain Shower Head

Rain shower heads are large and heavy and often connect to a long arm. Leaks usually start at the connection where the head meets the arm. The fix is the same as for a standard head. Use fresh plumber’s tape and check the washer. Because the head is heavy make sure the arm is firmly anchored in the wall since a loose arm will stress the joint and cause leaks.

Why Is My New Shower Head Leaking?

A brand new shower head that leaks is almost always an installation issue. Look for these common mistakes:

No plumber’s tape on the arm threads. Most heads need tape for a tight seal.
A missing or doubled washer. Check the inside of the connection.
Cross threaded installation. If the head would not screw on easily it may be at a slight angle. Back it off and start again.
Overtightening. Cranking the head too hard can crush the washer and cause a leak.
Leftover debris on the arm. Old tape or gunk on the threads can prevent a tight seal.

Shower Head Leaking When Off: Check the Valve

If your shower head drips long after you turn the water off the head is probably not the culprit. Water is passing through the valve behind the wall. There are two main reasons.

A worn cartridge. In a single handle shower the cartridge seals against the valve body. When the seals wear out water slips past. This is the most common cause. Our guide on how to replace a shower cartridge walks you through the repair.
A worn washer or seat in a compression faucet. In older two handle showers a rubber washer presses against a seat to stop the flow. When the washer hardens or the seat corrodes water leaks. You replace the washer on the leaking side. A damaged seat usually needs a plumber.

If water also comes out of the tub spout when you run the shower the diverter may be failing. That is a separate part that also needs replacing.

How to Stop a Leaking Shower Head Quickly

If you cannot fix it right now these quick steps can slow the drip:

Tighten the head by hand. A loose connection often accounts for a fast leak.
Wipe and dry the connection. This helps you see where the water is coming from.
Wrap new plumber’s tape. It takes two minutes and costs a couple of dollars.
Shut off the water to the shower. If you have a stop valve use it until you can make the full repair.

How Much Does It Cost to Fix a Leaking Shower Head?

The cost depends on the cause.

Plumber’s tape or a new washer: Under $10 for the parts. This fixes most connection leaks.
A new shower head: Many standard heads cost between $15 and $60 while premium or rain heads cost more.
A new cartridge: The part often costs $20 to $70 and a plumber replacement averages about $300 with a typical range of $200 to $400 according to This Old House.
Plumber labor: Rates generally run about $25 to $200 per hour depending on where you live. Many plumbers also charge a minimum service fee for short visits.

If a leak is costing you money on your water bill fixing it quickly pays for itself. A shower that drips continuously can waste a surprising amount of water over a month. For a broader look at what plumbing fixes cost see our plumbing repair cost guide.

When to Call a Plumber

Most shower head leaks are a DIY job. Call a professional if:

Water drips or sprays from the wall around the arm. That suggests a failing fitting behind the wall.
The head will not come off the arm or will not tighten back on. The threads may be damaged.
The shower arm is loose or turns in the wall. It needs to be secured properly.
The cartridge or valve is stuck or corroded. Forcing it can crack the valve body.
You see water stains on the ceiling or walls nearby. A leak inside the wall needs to be found fast.
Water pressure seems very high. A plumber can test the pressure and install a regulator if needed.

If you plan to open up the wall or update the whole shower anyway check our bathroom remodel cost guide to plan the budget. For more projects you can handle yourself see our DIY home improvement guide.

How to Prevent a Shower Head From Leaking Again

A few habits keep leaks from coming back:

Descale the head every few months. A vinegar soak takes five minutes of work and prevents clogged nozzles.
Use fresh plumber’s tape whenever you remove the head. Never reuse old tape.
Do not overtighten. Hand tight plus a gentle quarter turn is enough.
Replace washers when you notice them wearing. They cost pennies.
Install a water softener if your water is very hard. Scale shortens the life of every seal in the shower.
Keep an eye on water pressure. Pressure that is too high stresses fittings and seals.

Frequently Asked Questions About a Leaking Shower Head

How do you fix a leaking shower head?

Unscrew the head and replace the old plumber’s tape on the arm threads with fresh tape. Check the rubber washer inside the connection and replace it if it is worn. Clean mineral buildup with white vinegar then reattach the head and test it.

Why is my shower head leaking when the water is off?

If it keeps dripping for several minutes the shower valve or cartridge is likely worn. A small drip for a minute or two after shutoff is normal because water drains from the head and arm.

Why is my shower head leaking at the connection?

Worn plumber’s tape or a cracked or missing washer is the usual reason. Replace both and tighten the head by hand with a gentle quarter turn.

How do you stop a shower head from dripping?

Start by tightening the connection and replacing the tape and washer. If the drip continues after the shower is off replace the cartridge or the washer in the faucet valve. If the drip is from a sink faucet instead read how to replace a faucet cartridge.

Why is my new shower head leaking?

New heads usually leak because of an installation mistake. Common issues include no plumber’s tape and a missing or doubled washer or a cross threaded connection.

How much does it cost to fix a leaking shower head?

Many fixes cost under $10 for tape or a washer. A new shower head typically runs $15 to $60. If the cartridge needs replacement a plumber averages about $300.

Can mineral buildup cause a shower head to leak?

Yes. Scale clogs the spray holes and forces water out around the faceplate or the joints. Soaking the head in white vinegar usually clears it.

Final Thoughts on Fixing a Leaking Shower Head

Learning how to fix a leaking shower head saves you a plumber’s bill and a lot of wasted water. Work from the cheapest fix to the most involved. Tighten the head and renew the tape and replace the washer and clean out the scale. If water still drips after the shower is off look at the cartridge or valve behind the wall.

Keep a roll of plumber’s tape in the bathroom drawer and descale the head a few times a year. Those two habits head off most shower head leaks before they start. If the problem is in the wall or beyond your comfort level a plumber can sort it out quickly.
