Plumber for Faucet Repair: Costs, Common Fixes, and the Bathroom Upgrade Opportunity

A dripping faucet wastes 3,000 gallons of water per year, roughly 8 gallons per day, which adds $25 to $75 to an average American water bill annually. That's not dramatic, but it's money you're spending for nothing, and a dripping faucet is almost always a symptom of a worn cartridge or valve seat that gets progressively worse until it fails completely or starts leaking under the sink where you might not notice it for weeks.

Plumber faucet repair costs $100 to $450 in 2026 depending on faucet type, the specific failure, and local labor rates. That range includes the diagnostic, parts, and labor. Many repairs take under an hour. Some faucet problems, particularly on older or lower-quality fixtures, make more financial sense to replace than repair.

What Plumbers Actually Do for Faucet Repair

When a plumber arrives for a faucet repair call, the first step is diagnosis. Some faucet problems are obvious from the outside: a handle that spins without engaging, a base that wobbles, or visible corrosion around the supply connections. Others require partial disassembly to assess, particularly when the problem is internal valve wear or cartridge failure.

The most common faucet repair is cartridge replacement. Modern single-handle faucets use a cartridge, a self-contained valve unit, that controls the hot and cold water mix and the flow rate. Cartridges wear out over 5 to 15 years depending on water quality and use frequency. Replacement cartridges cost $15 to $80 depending on the faucet brand. Labor to replace a cartridge typically runs $75 to $150. Total: $100 to $250.

Ball valve repair addresses a different style of faucet mechanism. Ball-type faucets use a rotating ball to control flow and temperature. They fail through wear of the ball seat, spring, and O-rings. A rebuild kit costs $10 to $30. Labor to complete the rebuild runs $75 to $150. Total: $100 to $200.

Ceramic disc cartridge repair or replacement is common in higher-end faucets. The ceramic disc is durable but can crack or chip. Replacement disc cartridges cost $20 to $100 depending on the brand. Labor costs are similar to standard cartridge replacement: $75 to $150. Total: $100 to $275.

Stem and seat repair is the older compression faucet repair, still relevant in homes with original older fixtures. The rubber stem washer wears and causes dripping. Stem replacement costs $10 to $30 in parts. Labor runs $75 to $150. Total: $100 to $200.

Supply line replacement is often done simultaneously with faucet repairs. The flexible supply lines connecting the shutoff valves to the faucet should be replaced every 8 to 10 years. Replacing both hot and cold supply lines during a faucet service call costs $40 to $80 extra and takes 15 minutes.

When Faucet Repair vs. Replacement Makes Sense

Repair is the right choice when the faucet is relatively new (under 10 years), is a quality brand with available replacement parts, and the repair cost is less than half the cost of a new faucet installed. A $150 cartridge repair on a $400 Moen or Kohler faucet is a straightforward decision.

Replacement makes more sense when the faucet is old and showing multiple wear points, when parts are hard to source for discontinued models, when the finish is severely worn or corroded, or when the faucet style no longer suits the bathroom's look. A $200 repair on a $150 builder-grade faucet doesn't make financial sense when a new quality faucet with an installed cost of $250 to $400 gives you 10 to 15 years of reliable service.

The replacement opportunity is actually a bathroom planning conversation. Faucet replacement is one of the highest-impact, lowest-cost updates to a bathroom. Swapping a builder-grade faucet for a quality fixture with a modern finish, a waterfall spout, or a touchless sensor changes how the entire vanity looks. A plumber who replaces a faucet can also look at the supply valves, drain stopper, and overflow cover as a complete package for $300 to $600.

Bathroom Faucet Upgrade Costs

A plumber-installed bathroom vanity faucet replacement using a homeowner-supplied mid-grade faucet runs $150 to $300 in labor. Using a higher-grade faucet in the $150 to $400 range brings the total project cost to $300 to $700.

Kitchen faucet replacement is typically a bit more labor-intensive due to the confined workspace under a kitchen sink. Labor runs $175 to $350. Total with a quality kitchen faucet ($150 to $500): $325 to $850.

Shower valve repair or replacement is more complex than faucet work. A shower cartridge replacement runs $200 to $500 total. A shower valve and trim kit replacement, which changes the appearance and functionality of the entire shower control, runs $400 to $900 depending on valve type and trim style.

The Connection Between Faucet Service and Bathroom Health

A plumber working on a faucet has eyes under your vanity, which means they can see things you wouldn't otherwise notice. P-trap condition, supply valve corrosion, any water staining on the cabinet floor that suggests a past or current slow leak, and the condition of the drain stopper mechanism are all visible during a faucet service call.

A good plumber notes these things and brings them to your attention. It's not about upselling; it's about the fact that a $25 supply line that's showing rust at the connection is a $300 to $800 water damage claim waiting to happen. Finding it during a faucet service call and replacing it for $40 is the best possible outcome.

This is how smart bathroom maintenance works. A plumber who knows your bathroom, who has been there before and knows what's original equipment versus what's been replaced, is a real asset for a homeowner who wants to stay ahead of problems rather than react to them.

Frequently Asked Questions

Can I fix a dripping faucet myself? Yes, for many common faucet types. Single-handle cartridge faucets are particularly DIY-friendly because manufacturer websites often provide step-by-step repair videos for their specific models. You'll need to turn off the water at the shutoff valve, remove the handle, extract the old cartridge, install the new one, and reassemble. The whole job takes 30 to 60 minutes and costs $15 to $80 for the cartridge. If you're not comfortable working around the water shutoffs or if the faucet is an unusual type, calling a plumber is the right call.

How do I know what kind of faucet cartridge to buy? Find your faucet's brand and model number. The model number is often stamped on the faucet body behind the handle or on a tag attached to the supply lines when the faucet was new. With the brand and model, you can find the exact replacement cartridge through the manufacturer's parts site or a plumbing supply store. Using the correct OEM cartridge or a reputable aftermarket equivalent matters for fit and longevity.

What does it mean when water comes out around the faucet handle? Water leaking around the handle base typically indicates worn O-rings on the cartridge or valve stem. It's a repair that's usually straightforward if you catch it early. If ignored, it can damage the finish around the handle and, if it runs into the cabinet, create conditions for mold growth. Call a plumber or attempt the repair yourself using the faucet manufacturer's repair guide.

How long do bathroom faucets last? Quality faucets from established brands like Moen, Delta, Kohler, and similar manufacturers typically last 15 to 20 years or more with normal maintenance. Builder-grade faucets from lesser-known brands may need repair or replacement within 5 to 10 years. Cartridges and washers, the wear components, need replacement every 5 to 15 years. The faucet body itself rarely fails.

Is it worth replacing a faucet when doing a bathroom remodel? Almost always yes. Faucet replacement during a larger bathroom renovation adds $300 to $700 to the project but gives you a new fixture that matches the updated bathroom aesthetic and starts fresh with a full parts warranty. Installing a new faucet on old supply lines is also an opportunity to replace those lines as part of the scope, which is good preventive maintenance.
