A tub tap leaking may seem minor, but it adds up fast. A single drip per second can waste over 3,000 gallons a year. Many homes lose close to 10,000 gallons due to small leaks. That’s higher water bills, more wear on your plumbing, and real risks like mold and hidden wall damage. This guide follows a clear path: quick actions and diagnosis first; the real causes with data; cost and risk facts; tools and parts; step-by-step DIY repairs; advanced troubleshooting; prevention; and when to call a plumber. You’ll also get simple calculators, flowcharts, and checklists. Whether your bathtub faucet uses a washer, a cartridge, or ceramic discs, you’ll find a safe, clear way to fix the leak for good.
Quick answers: tub tap leaking — immediate actions
Noticing a bathtub faucet leaking can be frustrating, but you don’t have to panic. Here, we’ll show you how to fix a dripping tub faucet quickly, stop the drip, and prevent further damage—so you can take control before a small leak turns into a bigger problem.
30-second triage: shut off water, plug the drain, protect surfaces, capture drips
Act fast to control the situation and keep parts organized.
-
Shut off the water. Use the local tub shut-offs if present. If not, use the main shut-off. Open the faucet to relieve pressure.
-
Plug the drain. Use a stopper or rag so small screws and O-rings don’t fall through.
-
Protect surfaces. Lay down a towel to protect the tub and tile. Tape off the spout and trim if you’ll use tools near them.
-
Capture drips. Place a cup or small bucket under the dripping faucet to stop splashing and gauge leak rate.
Identify leak location fast: spout drip vs handle seep vs behind-wall hiss
Start by watching and listening. A drip from the spout with the water off points to worn internal seals like a washer, cartridge, or valve seat. Water seeping from the faucet handle or base usually means a failed packing, O-ring, or trim gasket. A faint hiss behind the wall, water stains, or a musty smell may signal a behind-wall leak or a failing valve body. Feel the temperature of the drip. Hot-only drips often tie to the hot side stem or cartridge seals; mixed-temperature drips hint at a pressure-balance or mixing issue.
When to stop DIY and call a plumber (no shutoff, crumbling valve, wet wall/ceiling)
Stop and call a licensed plumber if any of this applies: you cannot find or operate a shut-off valve; the valve body is cracked, severely corroded, or crumbling; you notice a warm or wet wall, ceiling stains, or mold; the handle won’t come off even after loosening the screwdriver-held set screw; the cartridge is seized and a puller doesn’t help; or the tub/shower valve is part of a complex system like a thermostatic mixer tied to multi-jet features and you’re not comfortable with calibration.
One-page decision tree
Follow this quick decision path:
Is the leak from the spout with faucet off?
- Yes: Identify faucet type (two/three-handle compression vs single-handle cartridge vs ceramic-disc). Service the washer/stem, cartridge seals, or disc seals. Inspect the valve seat.
- No: Is water seeping from the handle or trim?
- Yes: Replace packing, O-rings, and trim gaskets.
- No: Hear hissing or see damp walls? Do a pressure test and moisture check. Consider opening the wall and calling a pro.
After repair, still leaking?
- Check seat pitting, misaligned temperature stop, wrong cartridge type, or diverter cross-leaks.
- Persistent symptoms = pro evaluation.
Root causes and accurate diagnosis (data-backed)
Understanding why a tub tap is leaking is key to a lasting repair. In this section, we break down the root causes of a dripping faucet—from worn washers and cartridges to valve seat damage and hard-water buildup—using real-world data and expert insights. Accurate diagnosis helps you fix a leaky bathtub faucet effectively, avoiding repeated repairs and unnecessary costs.
Most common failures: worn washer/cartridge, O-rings, valve seat wear; hard-water mineral scale
Most tub faucet drips come from worn internal parts that no longer seal the flow of water. For classic two- or three-handle compression faucets, the rubber washer at the end of the faucet stem hardens and grooves over time. Each turn of the handle presses that washer against the valve seat. When the washer wears or the seat pits, water slips by and the bathtub faucet starts leaking. In single-handle cartridge faucets, the cartridge contains seals and O-rings that control hot and cold water. These seals wear, tear, or get fouled with scale, and the valve can’t fully shut.
Mineral buildup from hard water accelerates wear. Scale crystals scratch sealing surfaces and keep parts from sitting flush. You may notice white crust around the spout or aerators elsewhere in the home. That’s a clue the inside of your faucet may also be crusted. In these cases, even a new washer or seal can leak unless you descale the seat and mating surfaces.
Diagnose by faucet type
Start by naming your type of faucet:
-
Two- or three-handle compression: Separate hot and cold handles control the tub spout; a third handle may run a shower diverter. The inner part is a stem with a washer that seals against a seat. You often fix these by replacing the washer and stem packing, and by inspecting or replacing the seat.
-
Single-handle cartridge: One handle moves up/down and side/side to control flow and mix. The middle holds a cartridge that uses internal seals to shut water off. You usually fix these by pulling the cartridge, replacing seals and O-rings, or swapping the cartridge. Some models include a pressure-balance spool or temperature limit stop that also needs alignment.
-
Ceramic-disc and thermostatic mixers, including many Roman tub sets: These use flat ceramic discs or a thermostatic element to blend water. They are durable but can leak if grit or scale scratches the discs or if the seals and inlet screens clog. Repairs focus on cleaning, replacing seals, and recalibration.
Each system has different parts inside the faucet, so a clear ID helps you choose the correct repair steps and parts. If you’re unsure, remove the handle carefully and compare the internal layout to common designs in your owner’s manual or on the valve’s documentation (often stamped on the trim or under the handle).
Hidden issues in older homes
If your home is older, the leak can be more than a leaky faucet. Corroded valve bodies, split solder joints, or cracked galvanized pipes can pass water even when the handle is off. Signs include irregular drip rates, sudden changes in water pressure, a green/blue stain from copper corrosion, or brownish water at startup. You might also hear a faint hiss or ticking behind tile. Another clue is a showerhead that drips when the tub is on or right after shutoff—often a diverter or cross-leak issue. In short, if you’ve replaced “obvious” parts and it’s still leaking, the problem may be in the plumbing system behind the wall.
Why is my bathtub faucet still dripping after replacing the cartridge?
A new cartridge will not seal a damaged seat, fouled valve body, or misaligned mixing/temperature stop. Scale lodged in the valve can keep seals from sitting flat. The wrong cartridge model or reversed hot/cold orientation can also cause a slow drip. If you’ve swapped the cartridge and the faucet still leaks, inspect and clean the valve cavity, check the valve seat for pits, verify the stop alignment, and confirm you installed the correct part. If the drip persists, suspect a deeper issue like a cracked valve body or cross-flow from another fixture, and consider a pro pressure test.
Water waste, repair costs, and damage risks
A leaking tub tap is more than just an annoyance—it wastes water, drives up bills, and can cause serious damage over time. In this section, we’ll break down how much water a drip can lose, typical repair costs, and the risks to your walls, floors, and overall home. Understanding these factors helps you prioritize repairs and fix a leaky bathtub faucet before small issues turn costly.
Drip-to-gallons math
Even “tiny” drips are not small over time. Here’s a simple way to see the scale of wasted water.
Drip-to-gallons quick calculator:
-
Count drips for 15 seconds, multiply by 4 to get drips/minute.
-
Gallons per day ≈ drips/minute × 0.0117.
-
Gallons per year ≈ daily gallons × 365.
Essential figures you can use right now:
| Leak rate | Approx gallons/day | Approx gallons/year |
|---|---|---|
| 10 drips per minute | ~0.12 | ~44 |
| 1 drip per second (~60/min) | ~0.70 | >250 |
| 2 drips per second | ~1.40 | >500 |
| 1 teaspoon/min (~5 mL/sec) | ~18 | ~6,500+ |
| Small stream (not just drip) | 50–100+ | 18,000–36,000+ |
Many homes lose close to 10,000 gallons yearly from leaks according to the EPA’s WaterSense program. A bathtub tap that runs even a thin thread can exceed that on its own.
Money matters
Stopping a leaking bathtub faucet often pays you back quickly. Fixing common household leaks can trim water bills by about 10%. Typical tub faucet repair pricing ranges from $100 to $400 depending on parts and access, while plumber labor rates often run $45–$200 per hour, with a one-hour minimum common in many areas. A simple washer or O-ring replacement can be at the low end; a stuck cartridge, seized trim, corroded seat, or behind-wall work pushes costs higher. Full faucet replacement costs more due to trim and potential wall work, especially for tiled surrounds.
Answers to the questions most people ask:
-
How do I stop my bathtub tap from dripping? Identify your faucet type, replace the worn washer or cartridge, clean or replace the valve seat, and reassemble with fresh O-rings. Test thoroughly.
-
What is the most common cause of a leaky tub faucet? Worn washers in compression valves and worn or scaled seals in cartridge valves.
-
How much does a plumber charge to fix a leaky bathtub faucet? Many jobs land between $100 and $400 total. Complex valves or hidden leaks can cost more.
Structural and health impacts
Water that escapes in or behind walls is more than a nuisance. It can feed mold and mildew, rot subflooring, and stain ceilings below the bath. Wet drywall loses strength and may crumble. In a tight space with poor ventilation, even a slow dripping faucet can raise humidity and trigger growth on grout and caulk. Hidden leaks that travel to lower floors can lead to major repairs, and insurers may deny coverage for damage from long-term neglected leaks. Fixing the leak now is far cheaper than replacing drywall, tile, and framing later.
Is a slow drip really wasting that much water?
Yes. A drip every few seconds adds up to hundreds or thousands of gallons a year. That is water you pay to bring into the home and, in many places, to send down the drain. It also adds wear to your plumbing and raises the chance of secondary damage. Even if your bill is low, you are paying in other ways—noise, rust stains, and risk.
Tools, parts, and prep checklist
Before you start to fix a tub faucet or repair a leaky bathtub faucet, having the right tools and parts on hand makes the job faster and safer. This section covers essential tools and prep tips so you can tackle the leak efficiently and avoid common pitfalls. Being prepared ensures your repair goes smoothly from start to finish.
Essential tools and substitutes
You don’t need a full shop to fix a leaky tub faucet, but a few tools make it easier.
-
Adjustable wrench or box wrenches for nuts.
-
Phillips and flat screwdriver; small pick for O-rings.
-
Allen key (hex) for faucet handle set screws.
-
Cartridge puller for stuck cartridges; stem socket set for compression stems.
-
Seat wrench or seat dresser for valve seat removal/refacing.
-
Plumber’s grease for seals and threads.
-
White vinegar for soaking parts with scale; a soft brush to clean.
-
Utility knife, masking tape, towels, and a small bowl for screws.
-
Optional: moisture meter and flashlight to check for hidden damp spots.
No puller? Try wiggling the cartridge gently with two screws threaded into its body as makeshift handles, but avoid prying against tile or the trim.
Parts by system
Match parts to your type of faucet. Compression valves use a stem, washer, and packing. You may replace the washer only or the whole stem. Single-handle systems use a cartridge that may be brand- and model-specific; many universal cartridges fit multiple designs, but always check dimensions and alignment tabs. Ceramic-disc valves include seals, springs, and inlets with screens you can service. If you have a shower/tub diverter, you may need a new diverter stem or internal seals. Pressure-balance and anti-scald parts often have adjustable stops that must be set after reassembly.
Take the old part to the store or compare measurements carefully. A near match that is slightly off can lead to leaks or handle misalignment.
Safety first
Close the main or local water supply and test by opening the faucet. Keep a towel under the valve while you work. Wear eye protection when pulling parts under tension. If the valve has been stuck for years, be gentle to avoid cracking the escutcheon or tile. Tape pliers’ jaws to protect finishes. Do not force a cartridge with too much torque—use the correct puller. Always test at low flow first after reassembly to avoid sudden hot and cold swings.
Labeled bathtub faucet anatomy
Here’s what sits inside most tub/shower faucets:
-
Handle and set screw: what you grab to turn on/off.
-
Trim/escutcheon: decorative plate covering the wall opening.
-
Packing nut: holds the stem or cartridge in place and compresses packing.
-
Stem or cartridge: the working heart that opens/closes and mixes water.
-
Seals and O-rings: prevent seepage around moving parts.
-
Valve seat: metal seat the washer seals against (compression valves).
-
Diverter: sends water flow to the showerhead when needed.
-
Temperature stop or balancing spool: controls max hot temperature and pressure balance.
Knowing these names helps when you inspect the faucet and shop for parts.
DIY step-by-step repair (compression, cartridge, ceramic-disc)
Ready to fix a tub faucet yourself? In this section, we provide clear, step-by-step instructions to repair a leaky bathtub faucet, whether it’s a compression valve, single-handle cartridge, or ceramic-disc system. Follow these practical guides to stop drips safely, restore full function, and avoid repeated leaks.
Compression/two-handle
If your tub has separate hot and cold handles, you likely have a compression valve. The fix is usually an easy fix if parts are accessible.
Steps to fix:
-
Turn off the water supply and open the faucet to relieve pressure. Plug the drain.
-
Remove the handle. Pry the cap, loosen the set screw, and pull the handle off. Remove the escutcheon.
-
Unscrew the packing nut and withdraw the stem. Note the orientation.
-
Inspect the washer at the end of the faucet stem. If grooved or stiff, replace it. Also replace the stem packing or O-ring under the packing nut.
-
Shine a light into the valve body. Inspect the valve seat for pits or grooves. Use a seat wrench to remove it if replaceable, or a seat dresser to resurface it until smooth.
-
Clean scale with vinegar. Rinse and dry. Apply a thin film of plumber’s grease to threads and O-rings.
-
Reinstall the stem and packing nut. Hand-snug, then a quarter-turn with a wrench. Do not over-tighten.
-
Reassemble the trim and handle.
-
Turn the water supply back on and test the faucet. If it still drips, repeat on the other side, since either hot or cold can leak through to the spout.
Pro tip: If your tub has a separate diverter, service it too if the spout drips when the shower is on or your showerhead drips with the tub off.
Single-handle/cartridge
For a single-handle tub faucet, the cartridge does the sealing.
Steps to fix:
-
Shut off the water and open the faucet to bleed pressure. Plug the drain.
-
Remove the handle by loosening the set screw or top screw. Take off the trim/escutcheon.
-
Pull the retaining clip or nut holding the cartridge. Keep it safe.
-
Use a cartridge puller or gentle rocking to slide it out. Note its orientation.
-
Inspect the valve cavity for debris or scale. Clean with vinegar and a soft brush. Flush briefly with water (towel ready).
-
If reusing the cartridge, replace its O-rings and seals. If replacing, match the new cartridge to the old one exactly.
-
Grease O-rings lightly. Insert the cartridge in the same orientation. Install the clip/nut.
-
Set the temperature limit stop per the instructions so you avoid scalds.
-
Reassemble handle and trim. Turn on water slowly, purge air, and test hot/cold and shutoff. Check for seeping around the base of the faucet and handle.
If you have a pressure-balance unit, make sure the balancing spool moves freely. If it sticks, you can get strange temperature behavior or drips.
Ceramic-disc/thermostatic
Ceramic-disc and thermostatic valves last long but hate grit and scale.
Steps to fix:
-
Turn off water and open the faucet. Remove handle and trim.
-
Remove the disc cartridge or thermostatic element as a unit.
-
Clean inlet screens and seals. If discs are scratched, replace the assembly.
-
Soak parts with mineral deposits in vinegar; rinse and dry fully.
-
Reinstall with fresh O-rings and a thin film of plumber’s grease on seals.
-
Calibrate anti-scald or thermostat per the manual. Aim for a safe max temperature.
-
Reassemble, turn water back on, and test the faucet at low flow first.
Do I need PTFE tape on bathtub spout or valve threads?
Use PTFE tape on tapered pipe threads where the manufacturer calls for it, such as threaded tub spout connections or certain adapters. Do not use PTFE on compression or cartridge sealing areas inside the valve—those seal with washers, O-rings, or gaskets. If your spout uses a slip-fit with a set screw, tape is not used there either.
Troubleshooting persistent drips and complex scenarios
Sometimes, even after you fix a tub faucet, drips persist or unusual issues arise. This section helps you troubleshoot a leaky bathtub faucet in complex situations—like valve seat pitting, cross-flow between hot and cold lines, or behind-wall leaks—so you can identify the real problem and apply the right solution without guesswork.
Valve seat pitting
If a new washer still drips, the valve seat may be the villain. Run your fingertip or a cotton swab around the seat. If it snags, it’s pitted. When the seat is removable, swap it with a seat wrench. If fixed, use a seat dresser to refinish it until smooth and concentric. Clean out all brass shavings, then reassemble with a fresh washer or seal. A smooth seat is essential to a lasting fix.
Diverter and cross-leak symptoms
A showerhead that drips after you shut off the tub can point to a worn diverter or cross-flow between hot and cold. Cross-leaks can also pull hot water into the cold line (or the reverse) when you open another fixture, making the tub spout drip briefly. Service the diverter seals, verify the cartridge or balancing spool moves freely, and check that the hot and cold supplies aren’t reversed. If another faucet opening causes your tub spout to drip or hiss, that’s classic cross-connection behavior.
Behind-wall leak detection
Some leaks don’t show at the faucet. If you suspect a hidden issue, do a quick test:
-
Close the tub’s shut-off valve or main valve. Note your water meter reading. With all fixtures off, watch for movement over 15–30 minutes.
-
Use a moisture meter on the wall below and beside the valve. Compare to a known dry area.
-
Listen with a mechanic’s stethoscope or even a long screwdriver placed to your ear against the wall for a faint hiss.
-
Place a dye tablet in the tub spout stream when running, then shut it off. If colored water seeps from the base of the faucet or surrounding tile, water is escaping behind the trim.
Open the wall when you get repeated wet readings, see staining or swelling, or hear a steady hiss with the faucet off. Cut a small access panel on the opposite side of the wall if possible to reduce tile damage.
Why does my tub faucet drip hours after shutoff or when another fixture runs?
Residual water in the spout and upper piping can drain out slowly, causing brief drips, but hours of dripping usually point to a weak seal. When another fixture runs, pressure shifts can push water past a worn washer or cartridge seal. A sticky diverter or pressure-balancing spool can also let water migrate. The cure is to restore tight sealing surfaces and ensure the diverter and balancing parts move freely.
Prevention, maintenance, and when to call a plumber
Once you’ve successfully fixed a tub faucet or repaired a leaky bathtub faucet, regular maintenance is key to keeping it leak-free. This section covers simple prevention tips, annual checks, and signs that indicate it’s time to call a plumber—helping you avoid future drips, water waste, and costly damage.
Maintenance schedule
A little care keeps leaks from returning. Once a year, inspect the faucet trim for moisture, tighten loose handles, and check for scale. In hard-water regions, descale the spout, cartridge screens, and seats. Exercise local shut-offs so they don’t seize. Replace washers and O-rings at the first sign of seep around the handle. Check caulk lines around the tub and refresh if cracked to stop splash water from getting behind walls.
Long-term prevention
Hard water scratches seals and speeds wear; a softener or point-of-use filter helps. Excess water pressure can force water past seals and erode seats—keep it near 50–60 psi at the house with a pressure-reducing valve if needed. Use quality parts matched to your valve. Don’t over-tighten stems or packing nuts; too much torque can warp parts and start a new leak. A clean, lightly greased assembly lasts longer and runs smoother.
For homeowners looking to fully upgrade their bathroom experience, pairing a modern, high-quality bathtub faucet with a durable, stylish bathtub can transform both comfort and functionality. New bathtubs with smooth surfaces and anti-slip coatings not only enhance safety but also make cleaning easier, while precision faucets prevent leaks and drips. Together, a quality tub and faucet reduce maintenance, save water, and provide a relaxing, worry-free bathing experience for years to come.
Call a pro
If you’ve repaired more than once in a short time, the underlying valve or the plumbing system may be the issue. Heavily corroded valve bodies, frozen shut-offs, or signs of mold or damp walls call for a licensed plumber. Some valve replacements require access panels, reworking copper or PEX, or meeting anti-scald code rules. If permits or inspection apply in your area, a pro ensures compliance and safety.

Following these steps lets you fix tub faucets yourself safely, saving water, avoiding costly plumber visits, and keeping your bathroom leak-free for years.
2. What is the most common cause of a leaky tub faucet?
Tub tap leaking often stems from worn or damaged internal parts. In two-handle faucets, the rubber washer at the end of the stem can harden or groove over time, preventing it from fully sealing the valve. In single-handle cartridge faucets, O-rings and internal seals can deteriorate or get fouled with hard water deposits, which stop the faucet from shutting off completely. Minor leaks might seem insignificant, but even small drips waste hundreds or thousands of gallons annually and can lead to higher water bills and potential damage to walls or floors. Spotting and replacing these failing components early is essential. Understanding these common failure points gives homeowners the insight to take quick action, stop leaks, and prevent minor issues from escalating into costly repairs related to tub tap leaking.
3. Why is my tub spout dripping when the water is off?
When a tub tap leaking continues even with the water turned off, it usually means a seal, valve seat, or internal component inside the faucet is worn or damaged. Cross-flow from other fixtures or a faulty diverter can also allow water to drip into the spout. Hard water buildup can prevent seals from sitting flush, worsening the problem. If your spout drips hours after shutoff or only when other faucets are used, it indicates pressure imbalances or failing internal parts. Early inspection and replacement of worn washers, O-rings, or cartridges is critical. Addressing the underlying cause conserves water, prevents structural damage from hidden leaks, and avoids costly repairs. Recognizing the signs of persistent tub tap leaking ensures you can take action before it becomes a bigger issue.
4. How much does a plumber charge to fix a leaky bathtub faucet?
Fixing a tub tap leaking can cost anywhere from $100 to $400 depending on the type of faucet, parts needed, and accessibility. Labor rates generally range between $45 and $200 per hour. Simple repairs, such as replacing washers, O-rings, or cartridges, are on the lower end, while complex issues like corroded valve seats, seized cartridges, or behind-wall leaks drive costs higher. Homeowners confident with basic tools can tackle minor repairs themselves, but persistent or complicated leaks often require a licensed plumber to ensure the faucet functions correctly and safely. Knowing the potential costs helps homeowners plan repairs without delays. Timely intervention also prevents ongoing water waste, avoids damage, and provides peace of mind when dealing with tub tap leaking.
5. Do you need a plumber to replace a bathtub faucet?
Many minor repairs are DIY-friendly, but if a tub tap leaking persists, shut-off valves are difficult to access, or you notice corrosion or damp spots on walls, calling a plumber is recommended. Complex systems, like pressure-balance valves, thermostatic mixers, or diverters, often require professional installation and calibration to function safely. Plumbers ensure proper alignment, installation, and compliance with building codes. Even if you can replace washers or cartridges yourself, professional help can prevent repeated leaks and avoid structural damage to walls or floors. Promptly addressing the issue guarantees the faucet works smoothly and prevents minor tub tap leaking problems from turning into major repairs over time.
