Is your shower dripping hot water even when it’s turned off? A hot water leak from your shower faucet is more than an annoyance — it wastes energy, increases your utility bills, and can signal worn-out parts inside your faucet. The good news is that this issue is usually fixable with a simple repair. And if your faucet is older, replacing it may be the smarter long-term solution.
Why Is Hot Water Leaking from My Shower Faucet?
If only hot water drips from your shower faucet, here are the most common reasons:
- Worn cartridge: In single-handle faucets, the cartridge controls hot and cold mixing. When it fails, hot water often leaks through.
- Damaged washers or O-rings: In two-handle faucets, a worn washer on the hot side can cause dripping.
- Faulty valve seat: Corrosion inside the valve seat can prevent a proper seal on the hot side.
- Water pressure imbalance: High pressure can force hot water past weak seals.
Is a Hot Water Leak Dangerous?
While not usually dangerous, hot water leaks waste both water and energy. A small drip can waste over 2,000 gallons per year. If the leak worsens, it could also scald if someone touches the running water.
How to Fix a Hot Water Leak in a Shower Faucet
Here’s a general repair guide for most shower faucets:
- Shut off the water supply. Always turn off water before disassembly.
- Remove the handle. Use a screwdriver or Allen wrench to remove the handle and trim plate.
- Access the cartridge or stem. For single-handle faucets, remove the cartridge. For dual-handle faucets, remove the hot-side stem.
- Inspect and replace parts. Replace worn cartridges, washers, or O-rings.
- Reassemble and test. Turn water back on and check for leaks.
Tip: If you’re not sure of your faucet brand, bring the old cartridge or stem to a hardware store to match it with the correct replacement part.
When to Replace Instead of Repair
Sometimes replacing your shower faucet is better than repairing it. Consider replacement if:
- Your faucet is more than 10–15 years old.
- The leak continues even after replacing cartridges or washers.
- You want a style or efficiency upgrade.

FAQ
1. Why is only hot water leaking from my shower faucet?
It usually means the hot-side cartridge, washer, or valve seal has failed. Replacing those parts usually solves the problem.
2. Can I just replace the cartridge instead of the whole faucet?
Yes — in most cases, swapping the cartridge is enough. But if your faucet is old or corroded, a full replacement may be smarter.
3. How do I know if I need a new cartridge?
If your shower drips hot water constantly, or the handle feels stiff, it’s a strong sign the cartridge is worn out.
4. How much does a cartridge replacement cost?
Most cartridges cost $30–$80. A full faucet replacement kit runs $150–$400+, but includes all new parts.
Conclusion
If your shower faucet is leaking hot water, the problem usually comes from a worn cartridge, washer, or valve. You can often fix it by replacing the faulty part. But if your faucet is old, a full replacement is the best long-term solution. Modern faucets are designed to prevent leaks, save water, and provide steady temperature control.
