Shower valve replacement cost: $225 to $575 (HomeGuide 2026)

National figures. Brand, valve type and whether the tile has to come off move the total.

Do this now: a shower that drips, sticks or runs hot and cold

Three things settle most shower valve calls before anyone opens the wall, and the first one stops the water:

1. If it will not shut off, close the water. Use the stops behind the access panel if there are any, or the main shutoff; Phoenix Water Services says the main is usually at the front of the house near a hose bib, and to know where it is before you have to use it.
2. Note exactly what it does. Dripping from the head or handle when off, a stiff handle, a grinding sound, sudden temperature swings, or water from the tub spout and the head at the same time. HomeGuide and Angi both list these as valve signs, and the last one points to the diverter.
3. Find the brand. HomeGuide prices cartridge replacement by brand, $100 to $315 for a standard Moen against $145 to $345 for a Moen Posi-Temp, and says some manufacturers warrant cartridges for life, so check before you buy one.
4. Look below and around. Angi's shower pan guide says water stains on the ceiling under the shower, moldy grout at the base, or a pan that moves underfoot point to the pan rather than the valve.
5. Call the plumber line. Ask for the service call fee and whether a cartridge, a valve, or the valve plus tile work is being quoted.

Is it urgent? When a shower valve cannot wait

A shower valve is rarely an emergency once the water is off, and after-hours work adds $100 to $300 or more in HomeAdvisor's 2026 plumber guide, so a drip you can stop at the shutoff can wait for a weekday price.

• Call now: water you cannot shut off at the fixture or the main, or water coming through the ceiling below. See burst pipe repair if a pipe has let go behind the wall.
• This week: scalding temperature swings, which Angi lists as a reason to replace rather than repair, or a handle that no longer turns.
• Can wait: a slow drip from the head with the water off. Angi says a minor leak or slight pressure drop may take only a new O-ring.

How much does shower valve replacement cost?

Shower valve replacement costs $225 to $575 in HomeGuide's guide, dated August 2025, with a $400 national average and a $145 to $900 full range. Angi's July 2026 data lands a little lower at $150 to $550, with a $350 average.

Both guides split the bill the same way. HomeGuide puts plumber labor for a valve at $100 to $300 and the job at 1.5 to 3 hours; Angi puts a handyperson at about $165 and a licensed plumber at about $225 for a system upgrade, with an extra hour of labor for an older or hard-to-reach valve. Plumber rates run $45 to $150 an hour (HomeGuide) or $45 to $200 (Angi). A faucet permit, where a city or county requires one, is $10 to $25 in Angi's figures; HomeGuide lists plumbing permits at $30 to $300.

Shower cartridge replacement vs the whole valve

A shower cartridge replacement costs $100 to $350 in HomeGuide's guide, against $225 to $575 for the valve, because the cartridge is $15 to $85 and the plumber's time is 30 minutes to 2 hours instead of 1.5 to 3.

HomeGuide, August 2025. Totals include the plumber's labor of $85 to $265.

HomeGuide says replacing internal parts like the cartridge or stem costs less than the whole valve assembly and can fix some problems on its own. Angi draws the line by symptom: a minor leak or slight pressure drop may be a repair, while serious leaks, pressure or temperature drops that make showering difficult, or odors from the valve call for replacement.

Shower valve types and what each costs

A pressure-balancing valve costs $150 to $600 installed and a thermostatic valve $250 to $900 in HomeGuide's guide, and the valve type is the biggest reason two quotes for the same shower differ.

Angi prices the part; HomeGuide prices the part and, where shown, the installed job. Labor is added separately in Angi's guide.

• Pressure-balancing valves hold the mix steady when someone flushes or runs a tap. Part $50 to $300 in both guides.
• Thermostatic valves hold a set temperature; HomeGuide prices the part at $150 to $600, Angi at $25 to $200, so ask which model is quoted.
• Diverter valves send water to the spout or the head. HomeGuide says a tub spout that leaks while the shower runs most likely means a faulty diverter.
• Transfer valves switch between outlets such as a head and a handheld; Angi lists the part at $100 to $190.

Shower faucet repair cost: leaks, handles and trim

A plumber charges $125 to $350 to fix a leaky shower faucet in HomeGuide's guide, with a repair kit of washers, gaskets and O-rings at $5 to $40, new handles at $30 to $120, and a full shower faucet replacement at $250 to $800.

Angi's examples of a repair are a new O-ring or tightening a pipe. For a drip you have traced to the toilet or the sink instead, see toilet repair cost; for a drip you cannot trace, leak detection.

What opening the wall adds: tile, drywall and access

Tile removal adds $7 to $25 per square foot and drywall repair $300 to $1,500 or more in HomeGuide's guide, which is why a valve with no access panel behind it can cost more to reach than to replace.

• HomeGuide lists a shower drain pipe replacement at $300 to $350 and new shower plumbing at $450 to $1,800 if the rough-in is changing too.
• Angi says older or hard-to-reach valves take about one hour of extra labor; ask whether the quote assumes an access panel.
• High-end assemblies from Kohler, Rohl or Grohe run $500 or more for the valve alone (HomeGuide).

Shower pan replacement cost and signs of a leaking shower pan

Shower pan replacement costs $900 to $2,300 for most projects in Angi's March 2026 guide, with a $1,620 average and a full range of $530 to $4,600; a pan typically lasts about 10 to 15 years.

• Signs the pan is leaking (Angi): the pan moves under your feet, visible cracks, water stains on the ceiling or seams below the shower, moldy grout near the base, or mold and mildew that suggest the pan is not holding water.
• By material (Angi): fiberglass $150 to $450, acrylic $200 to $600, hot mop $225 to $500, poured mud $350 to $650, cast iron $800 to $1,300, custom tile $900 to $3,500, plus installer labor of $350 to $570 and about $250 to remove the old pan.
• Extras: moving plumbing $600 to $1,600, permits $30 to $500, a new shower door $600 to $1,350 (Angi).
• A leaking pan that has reached the ceiling below is a drying job as well as a plumbing job; see water damage restoration.

Questions to ask before you approve a shower valve quote

• Cartridge or whole valve, and why? Ask what the plumber found when the trim came off.
• Which valve type and brand? Pressure-balancing and thermostatic parts differ by hundreds of dollars.
• Is wall or tile access in the price? And who repairs the tile or drywall afterward.
• Is there a cartridge warranty? Some brands replace cartridges for life (HomeGuide).
• License number and proof of insurance. Ask for the plumber's license number and proof of insurance yourself; the plumbing license table shows who licenses plumbers in six states.

If the pressure is weak at every tap, not just the shower, start with low water pressure in the house. Low hot water only usually points to the heater; see water heater repair.
