Calling a Plumber for Faucet Repair: What It Costs and When to Upgrade Your Bathroom

A dripping faucet that drips once per second wastes more than 3,000 gallons of water per year — and at average US water rates, that's $25 to $45 in wasted water annually before you even count the hot water energy cost. That's the practical case for faucet repair. But the more common story I hear from homeowners is that they call a plumber about the leaky faucet and end up in a much bigger conversation about their bathroom. Once a plumber is under the sink, they often notice the drain is slow, the supply valves haven't been turned in 15 years, and the faucet itself is corroded past the point where repair makes financial sense. That small faucet call opens a window into the broader state of the bathroom's plumbing.

Faucet repair by a licensed plumber runs $150 to $300 for most standard repairs — replacing cartridges, O-rings, seats, or stems in common faucet brands. Faucet replacement (buying a new faucet and having the plumber swap it in) runs $200 to $450 including parts, depending on the faucet price point and whether the supply lines and shutoff valves need replacement too. These are legitimate, reasonable repair jobs. But they're also the moment to ask the bigger question: what's the overall state of my bathroom, and is it time for a real upgrade?

What a Plumber Faucet Repair Service Covers

When you call a licensed plumber for a leaking or dripping faucet, the service call typically starts with a diagnosis — $75 to $150 for the trip charge in most markets, which is applied toward the repair cost with most companies. The plumber identifies the failure point (worn cartridge, failed O-ring, cracked seat, corroded valve body) and gives you a repair estimate.

For a standard repair on a common faucet brand (Moen, Delta, Kohler, American Standard), the cartridge or internal mechanism is usually available at any plumbing supply house or big-box store for $15 to $60. Labor to replace a cartridge runs 30 to 60 minutes. Total cost: $150 to $250 for most faucet repairs.

If the faucet body itself is damaged, corroded through, or so old that parts aren't available, replacement is the right call. The plumber provides a faucet (or you can supply your own from a retailer), and the swap typically takes one to two hours including replacing supply lines and testing for leaks. A basic replacement faucet runs $40 to $150; mid-range options $150 to $400; premium brands like Brizo, Grohe, or high-end Kohler start at $400 and go well above $1,000. Labor for replacement runs $100 to $250 depending on access and complexity.

What Plumbers Find Under the Sink That Changes Everything

Here's where faucet calls turn into bigger conversations. The area under a bathroom vanity is often one of the least-maintained spaces in a home — out of sight, out of mind, until something leaks or a plumber has to get in there.

Shutoff valves that haven't been operated in a decade are often frozen or corroded. If the plumber needs to turn off water for a repair and finds a non-functional shutoff, they have to cut the water supply at the main — and now you're looking at shutoff valve replacement too ($75 to $200 per valve). Many plumbers will proactively recommend replacing shutoffs that look questionable during any faucet service call.

P-trap and drain issues are common. Old chrome P-traps corrode and slow drains are often caused by buildup in the trap or drain stopper mechanism. Having the plumber address the full drain stack (clear the trap, clean the stopper mechanism, check the pop-up assembly) adds $50 to $150 to the call but is worth doing while they're already there.

Supply lines — the braided or chrome lines connecting the shutoff valves to the faucet — should be replaced every seven to ten years. Old supply lines are a common source of under-sink leaks that cause cabinet damage or floor damage if not caught. Supply line replacement adds $30 to $80 per line in parts and minimal labor.

When the Faucet Call Becomes a Bathroom Conversation

A plumber working on your faucet is looking at the entire visible plumbing situation in that bathroom. If they're good at what they do — and if they're honest — they'll tell you what they see. The corroded angle stops. The stained basin where there's clearly been slow leaking. The caulk around the tub that's been failing for years. These are signals.

The question homeowners should be asking themselves when the plumber is already there is: what's this bathroom actually worth to me, and is a faucet repair just delaying the inevitable? If the vanity is 25 years old, the tile is dated, and the toilet still has a running flapper, you're looking at a bathroom that's accumulating deferred maintenance. Fixing the faucet for $220 makes sense. But if you're planning to remodel within the next few years anyway, a conversation about that scope — and getting quotes from bathroom remodeling contractors — is worth having now.

Plumbing in the Context of a Bathroom Remodel

When a full bathroom renovation is on the table, the plumbing component is one of the more significant cost drivers — typically $1,500 to $5,000 for a standard bathroom remodel, depending on whether fixtures are staying in place or being relocated. A plumber who did your faucet repair and knows your bathroom's existing condition is actually a useful resource for that conversation. They can tell you whether the existing rough-in is sound, whether the drain lines are in good shape, and what the plumbing portion of a larger renovation would realistically involve.

Getting quotes for a full bathroom renovation requires a different contractor than a faucet repair — you want a bathroom remodeling contractor or general contractor who manages tile, fixtures, and plumbing together rather than managing each trade separately yourself.

Frequently Asked Questions

Is it worth repairing a faucet or should I just replace it? For faucets less than 10 years old from quality brands (Moen, Delta, Kohler), repair is usually worth it. For older faucets, heavily corroded valves, or if parts aren't available, replacement makes more sense. Ask your plumber to assess the overall condition of the faucet body before recommending repair over replacement.

Can I buy my own faucet and have the plumber install it? Yes, and most plumbers will install a customer-supplied faucet. You save on the markup the plumber adds to parts. Just make sure the faucet you buy is compatible with your existing rough-in (single-hole vs. three-hole) and that you have the installation instructions ready. Some plumbers charge a slightly higher labor rate for customer-supplied fixtures.

How do I know if my faucet is leaking from the supply lines vs. the faucet itself? Dripping from the spout when the faucet is off indicates an internal failure (cartridge, seat, O-ring). Moisture under the sink near the connections indicates a supply line or shutoff valve leak. A slow drip from the base of the faucet often means a worn base O-ring. Each has a different repair, so knowing which you have helps set expectations.

Do I need a licensed plumber for faucet repair, or can any handyman do it? In most states, simple faucet repairs and replacements fall in a gray area — handymen can legally do them in many jurisdictions. However, if work involves cutting into supply lines, replacing valves, or anything that requires touching the plumbing system beyond fixtures, a licensed plumber is legally required in most states and is the right call for quality and liability reasons.

How much does an emergency plumber charge for a faucet repair? Emergency or after-hours plumber rates run 1.5x to 2x the standard rate. A faucet repair that would cost $200 during business hours might run $300 to $400 on evenings or weekends. Unless the faucet is actively flooding (which it won't be — shut off the angle stop), wait for a standard service call.
