Shower Repair
A shower that drips all night, sprays weak, or swings from hot to cold is trying to tell you something. The cause often hides behind the wall, inside the valve that mixes your hot and cold water. Find that cause, fix it at the source, and the shower feels new again.
Why Showers Fail, and How a Pro Finds It
Most shower trouble traces to a small set of parts. The cartridge inside the valve wears and lets water pass when it should stop. Mineral scale clogs the head and the screens. Seals dry out and let water past. The valve body itself can corrode over years. Each fault has a different symptom, and a pro reads the symptom to pick the part, instead of replacing parts at random.
The Deston is a referral service, not a plumbing company. We connect homeowners across all 50 states with independent local plumbers who diagnose and fix shower problems every day. We do not send our own technicians. We match you with a nearby pro, you get an upfront price, and the work gets done right. The referral costs you nothing. You pay the plumber for the work, after you approve the price.
Shower trouble starts small and gets worse. A drip wastes water around the clock. A weak spray hints at scale that will only build. A temperature swing can scald, which matters most in homes with children or older adults. A stiff handle hints at a cartridge that has seized. Acting early keeps most shower repairs to one visit and one part.
Signs Your Shower Needs Repair
Watch for these warnings. Each one points to a specific fault a plumber can fix.
The shower head keeps dripping
A head that drips hours after you turn the water off has a worn cartridge or washer in the valve. The drip wastes water around the clock and stains the tub or base. A new cartridge usually stops it at once.
Water pressure has dropped
A once strong spray that turned weak usually means mineral buildup in the head or a clogged screen. If every fixture lost pressure, the cause sits deeper in the supply line. A plumber tests both and tells you which one it is.
The temperature swings mid-shower
Water that goes hot, then cold, then hot again points to a failing pressure balancing cartridge. This is more than annoying. It can scald. A new cartridge restores steady temperature and safety.
The handle is stiff or spins freely
A handle that fights you or turns without changing anything has a stripped stem or a cartridge that has seized. Forcing it can break the valve body and turn a part swap into a valve job. Stop forcing it and call.
Water leaks from the handle or trim
Water at the trim plate means a seal has failed behind the handle. That water runs into the wall, where it can rot framing and feed mold. A seal or cartridge swap, done early, keeps the wall dry.
The shower drain smells or drains slowly
A slow drain often means hair and soap buildup in the trap or the line. A smell can mean a dry trap, a blocked vent, or a drain seal fault. A plumber clears the line and checks the trap and vent, not just the drain cover.
From Call to Fixed Shower, in Six Steps
Most shower repairs take one visit. Valve jobs behind the wall take longer, but the flow stays the same.

Repair or Replace: The Honest Call
Repair wins when the fault is one part and the rest of the shower is sound. A cartridge, a head, a seal, or a caulk line each cost far less than a new shower. If the valve body is sound and parts are still made, a repair can give the shower years more life. Ask the plumber how long the repair should last, and what would make replacement the better call.
Replace wins when the valve body is corroded, parts are no longer made, or the base and walls are worn out too. A third failure in a year is a sign the system is done, not just one part. In that case, a new install costs more once but ends the cycle of visits. See shower installation for the full replacement path, and ask the plumber to price both options.
Temperature safety deserves its own note. A pressure balancing cartridge guards against scalds when a toilet flushes or a tap opens elsewhere. If your shower lacks that protection, a valve upgrade is worth doing even when the old valve still works. Homes with children or older adults should treat steady temperature as a safety item, not a comfort item.
Shower Repair Services
One referral can cover the head, the valve, and the drain.
Cartridge and valve repair
Worn cartridges, stiff handles, drips, and temperature swings. The pro matches the cartridge to your valve brand, swaps it, and tests temperature at several settings. Full valve replacement behind the wall is available when the body itself has failed.
Head, hose, and trim repair
Weak spray, clogged heads, leaking hand shower hoses, and loose trim. Heads are cleaned or replaced, hoses swapped, and trim resealed. A new head often restores spray at once when scale is the cause.
Drain, seal, and caulk repair
Slow drains cleared, drain seals fixed, and failed caulk replaced. Caulk lines at the base, corners, and door keep water in the shower and out of the wall. Re-caulking is a small job that prevents large wall damage.
Repair Now vs. Wait and See
Waiting rarely helps a shower fault. This guide shows why early repair wins.
| Factor | Repair now | Wait and see |
|---|---|---|
| Drip cost | One cartridge, water saved | Water wasted daily, stain grows |
| Wall risk | Seal fixed, wall stays dry | Leak into wall, rot and mold risk |
| Temperature | Steady, scald risk cut | Swings continue, scald risk stays |
| Total cost | One visit, one part | Valve body may fail, bigger job |
| Best when | Symptom just started | Never the better plan for a leak |

Preparing for the Repair Visit
A little prep helps the plumber finish in one visit.
Note the symptom clearly. Drip, weak spray, swing, stiff handle, or leak, and when it started. Patterns help the plumber pick the right part.
Find the valve brand if you can. A brand mark on the trim plate helps the plumber bring the right cartridge. A photo of the trim helps too.
Clear the shower area. Remove bottles, razors, and items from shelves and niches so the plumber can work and test without moving your things.
Plan for water off time. Valve work needs the shower water off, and sometimes the house water off, for part of the visit. Fill a jug if needed.
Mention past repairs. If the shower was repaired before, say what was done. Repeat failures point to a deeper fault than one part.
Keep the bathroom clear. Keep pets and kids out of the bathroom during the visit. Tools and open valve parts make it unsafe for wandering.
Frequently Asked Questions
Why does my shower head drip after I turn it off?
A short drip after shutoff is normal as water leaves the head. A drip that lasts hours means a worn cartridge or washer in the valve lets water pass when it should stop. A cartridge swap usually stops it. If the drip continues after a new cartridge, the valve body may be worn and need replacement.
Why is my shower pressure low?
Mineral scale in the head is the most common cause. Soak or replace the head first. A clogged screen at the valve or the head can also cut flow. If every fixture lost pressure, the cause sits deeper, such as the pressure regulator or the main supply. A plumber tests pressure at several points to find it.
Why does my shower go hot and cold?
A failing pressure balancing cartridge is the usual cause. It should adjust the mix when pressure changes elsewhere in the house. When it wears, temperature swings with every flush or tap. A new cartridge restores steady temperature and cuts scald risk.
Can I replace a shower cartridge myself?
Some homeowners do, but valve brands differ and a wrong cartridge can damage the valve body. Water must be shut off correctly, and the old cartridge can seize in place. A plumber brings the right cartridge, the right puller tool, and tests temperature after the swap. For most homes, a pro visit is worth it.
How long should a shower cartridge last?
Cartridges last years in soft water and fewer years in hard water, where scale wears seals faster. Hard water homes should expect more frequent swaps. Cleaning the head and softening water can extend cartridge life. If you replace a cartridge yearly, ask the plumber to check water hardness and valve condition.
What if my shower valve parts are no longer made?
Older valves can outlive their parts. A plumber may find a compatible cartridge, or may advise a valve replacement with a current model. A valve replacement behind the wall costs more than a cartridge swap, but it resets the shower for years and adds modern temperature control.
Why does my shower drain smell?
A dry trap, hair buildup, or a blocked vent can all cause smell. Run the shower and see if the smell fades as the trap fills. If it stays, the trap or vent needs a look. Never pour harsh chemicals down a smelly drain without advice, they can damage seals and hide the real cause.
Is a leaking shower an emergency?
A leak you can see at the trim or base should be fixed soon, because water runs into the wall unseen. A leak through a ceiling below is urgent: stop using the shower and call at once. A drip from the head wastes water but rarely floods, so it can wait a short time for a booked visit.
How do I stop scale from clogging my showerhead?
Clean the head in vinegar solution when spray weakens, and wipe the face dry after showers in hard water homes. A water softener cuts scale across the whole house. A filter head helps taste but does less against scale. Ask the plumber about softening if scale returns fast.
Does The Deston charge homeowners for referrals?
No. Our matching service is free to you. You only pay the local plumber for the work done in your home. You approve the plumber price before work starts. The Deston is a referral service that connects homeowners with independent local plumbers. We are not a plumbing company.
When should I replace instead of repair?
Replace when the valve body is corroded, parts are gone, or failures repeat within a year. Replace when the base is cracked or the walls are worn too. A plumber can price both paths so you can pick with facts. Repair wins when one part failed and the rest of the shower is sound.
