- Some manufacturers warranty their shower cartridges for life. Confirm whether the cartridge is covered under warranty before purchasing a replacement.
- Cartridges are not interchangeable across brands.
- Match the part number of the new cartridge to the old cartridge to verify compatibility.
Shower mixing valve replacement cost
Replacing a shower mixing valve costs $225 to $575 on average for materials and labor. The cost to replace a mixer valve depends on the valve type, brand, and accessibility. Replacement costs more for thermostatic valves or valves that must be accessed through the back of the wall.
|Valve type||Valve unit cost||Total replacement cost*|
|Pressure-balancing||$50 – $300||$150 – $600|
|Thermostatic||$150 – $600||$250 – $900|
*Including valve with installation
Shower mixing valves come in three types:
- Pressure-balancing shower valves have a single handle that controls both water temperature and flow volume. Pressure-balancing valves adjust the hot and cold water pressure to prevent the shower water from becoming scalding when cold water is used elsewhere in the house, such as when a toilet is flushed.
- Thermostatic shower valves automatically adjust the hot or cold water flow to maintain water pressure and temperature and prevent scalding. Thermostatic valves have two handles—one to control temperature and one to control flow volume—allowing users to adjust the two settings independently.
- Standard mixing valves draw water from the hot and cold taps but can't regulate sudden changes in water pressure. Mixing valves are more common in older homes and do not offer any anti-scald protection.
Cost to replace shower diverter valve
Replacing a shower diverter valve costs $225 to $575, including materials and labor. A shower diverter valve switches the flow of water between the bathtub spout or shower head and is typically controlled by a small handle located on the center trim plate or near the tub spout.
Faucets with both a fixed shower head and handheld shower head typically include a built-in diverter valve to route water to one shower head or the other. Transfer valves allow water to flow to multiple components at the same time.
Cost factors for plumbers to install a shower valve
Replacing a shower or tub faucet is a common home improvement during a bathroom remodel. The following factors affect the cost to install or replace a shower valve:
- Repair vs. replace – Replacing internal parts like the cartridge or stem costs less than replacing the entire valve assembly.
- Accessibility and complexity – Easily accessible shower valves cost less to replace. If the valve can't be accessed from a hole behind the center trim plate, the plumber may need to remove tiles, use an access panel, or go through a wall behind the shower.
- Shower tile repair costs $7 to $25 per square foot if the plumber removes tile to access the shower valve.
- Drywall repair costs $75 to $150 to patch a small to medium-sized hole if the plumber opens the wall behind the shower to access the valve.
- Material and replacement parts cost vary based on the brand, style, and finish. Some assemblies for high-end brands like Kohler, Rohl, and Grohe cost $500 or more. Cheaper generic options are also available from major manufacturers.
- DIY vs. professional labor – DIY shower valve replacement saves $100 to $300 on labor costs. Replacing a shower valve is a challenging project that may require removing a section of the wall to access the valve and surrounding pipes.
- Home warranty – Some home warranties cover shower valve replacement. Check the warranty policy to confirm the coverage details.
- Plumbing permits cost $30 to $300 for small jobs. Most cities require a permit for plumbing changes.
Labor cost for plumber to replace shower valve
Plumbers charge $100 to $300 for labor alone to replace a shower valve or $225 to $575 for the valve with installation. Replacing a shower valve takes 1.5 to 3 hours on average, depending on type and accessibility. Replacing a shower cartridge takes 30 minutes to 2 hours.
- Professional plumber hourly rates are $45 to $150 if additional repairs are needed.
- Handyman prices are $50 to $125 per hour to install a shower valve.
Replace shower plumbing pipes
- Replacing plumbing pipes costs $300 to $350 for the shower drain only.
- Installing shower plumbing costs $450 to $1,800 for a new shower or bathtub instead of replacing an existing fixture.
Additional costs to fix a leaking shower
Additional costs to repair a leaky shower faucet may include:
- A shower valve repair kit costs $5 to $40 and contains replacement washers, gaskets, and O-rings to prevent leaks.
- New shower handles cost $30 to $120 and are sold as part of a shower valve rebuild kit.
- Fixing a leaky faucet costs $125 to $350, depending on the source of the leak.

Signs you need to replace the shower valve
Signs a shower valve needs to be replaced:
- Dripping or leaking water even when the shower is turned off
- Shower handle gets stuck or is difficult to turn
- Grinding sound when turning the shower handle
- Sudden changes in water temperature
- Weak or inconsistent water pressure
- Water trickles but doesn't come out of the faucet
- Corrosion or sediment buildup in the valve assembly
What is a shower valve and assembly?
A shower valve regulates the flow of hot and cold water to maintain a consistent water temperature. The valve prevents temperature fluctuations in the shower when hot or cold water is used elsewhere in the home, such as when a toilet is flushed.
Shower valves typically must be paired with a faucet trim kit from the same brand. Some shower trim kits come with new valves, while others require a compatible valve sold separately.
What type of shower valve do I have?
To determine your type of shower valve, look for a brand name or symbol on the center trim plate, handle, or spout:
- Moen shower valves are labeled "M".
- Kohler shower valves are labeled "K".
- Delta, Price Pfister, American Standard, and others print the full brand name on the spout or center trim plate.
If no brand name or symbol is visible on the trim, the cartridge must be removed for identification based on its length and the size and shape of the broach on its stem. Refer to a cartridge identification guide or bring the cartridge to a local hardware store.
Can you replace a shower faucet without replacing the valve?
You can replace a shower faucet without replacing the valve if the stem is not damaged. The faucet—also known as the shower trim—includes the visible center plate, spout, and control knobs or handles. The valve is located inside the wall and can't be seen without removing the trim.
Most trim kits are only compatible with valves from the same brand. Before purchasing a new shower trim kit, confirm it is compatible with the existing valve.
How high should a shower valve be installed?
A shower valve should be installed 38 to 48 inches above the floor for showers without a tub. For showers in bathtubs, install the valve at a standard height of 28 inches.
How far should a shower valve stick out from the wall?
The distance a shower valve sticks out from the wall varies by style and manufacturer. Shower valves come with a round plastic piece called a plaster guard that should be aligned flush with the finished wall during installation to ensure the valve is placed at the correct depth.
Are shower valves and cartridges universal?
Shower valves and cartridges are not universal and are not interchangeable between faucets or brands. Each manufacturer uses brand-specific cartridges, and the correct cartridge type depends on the shower valve type. When replacing an old cartridge, use a new cartridge with the same part number.
Can you run two shower heads with one valve?
Running two shower heads with one valve results in a loss of water pressure whenever both shower heads are used simultaneously.
- When using a pressure-balancing valve, the water pressure from each shower head is halved if both shower heads are running simultaneously.
- When using a thermostatic valve, the total pressure is split between both shower heads, but the water volume from each head may be adjusted independently.
- When using the same valve for two shower heads, both heads run at the same temperature.
- Dual-unit faucets with one fixed shower head and one handheld shower head typically include a built-in diverter to route water to one shower head or the other.
Finding and hiring a plumbing service
Before hiring a plumber to replace a shower valve, be sure to:
- Get at least three estimates from local plumbers to compare.
- Look for plumbers with experience repairing showers.
- Browse their reviews on HomeGuide, Google, and the Better Business Bureau (BBB).
- Select companies that are insured, bonded, and have been in business for more than five years.
- Avoid selecting the lowest quote as quality may suffer.
- Get a detailed estimate, contract, and warranty in writing before the work begins.
- Confirm if a manufacturer's warranty covers the malfunctioning parts.
- Never pay in full before the project starts. Follow a payment plan instead for work completed.
