Understanding and Preparing for the Repair
Before you start unscrewing anything, it’s important to know what’s causing the problem and how to approach it. Following these preparatory steps ensures a smoother repair process.
Identify the Cause of the Leak
Most leaks in bathtub faucets happen because of a worn-out washer, which is the most common cause, a damaged cartridge, or a failing seal that compromises the watertight connection. These small components inside the fixture create a tight seal, preventing water from escaping. Over time, wear-and-tear damages these parts, leading to leaks.
If your bathtub has separate handles for hot and cold water, one or both may be the culprit. Faulty faucet handles, stems, or valves can also allow water to drip. The stem plays a crucial role in the overall functionality of the faucet, and a faulty stem can be a significant cause of leaks.
Know Your Faucet Type
Bathtub faucets generally fall into two main types:
- Single-Handle Faucets control both hot and cold water with one lever.
- Two-Handle Faucets have separate controls for hot and cold water.
Identifying the type helps you know which parts you may need to replace. It is crucial to understand the type of faucet before attempting any repairs.
Gather the Necessary Tools and Parts
Save yourself a trip to the hardware store by assembling your tools and supplies before starting. Here’s what you’ll likely need:
- Screwdrivers
- Adjustable wrench
- Pliers
- Replacement parts like washers, cartridges, or seals
- Plumber’s tape
- Towel to catch excess water
- Bowl or bucket to hold loose parts
Turn Off the Water Supply
Before proceeding with the repair, turn off the water supply to prevent further damage or a messy flood. You can usually find the shut-off valve near the water meter or under the sink. Verify it’s off by turning on the faucet handles to fully drain any leftover water.

Diagnosing and Repairing the Leak
Now that you’re prepared, it’s time to locate the specific issue and fix a leaking bathtub faucet promptly. Follow these steps to make sure everything goes smoothly.
Step 1: Remove the Faucet Handle(s)
Unscrew the faucet handles to access the valve. Use a screwdriver to carefully work on removing the knob or cap covering the screws. Place all loose screws in a small bowl to avoid losing them.
Step 2: Identify the Faulty Component
Once the handle is removed, check the washer, cartridge, or valve seat for damage. Look for signs like cracks, mineral buildup, or worn edges. Ray ID markings or visible corrosion can also be signs of failure. Correctly identifying the faulty component is crucial to avoid making a costly mistake.
Step 3: Replace Worn-Out Parts
- For Washers: Pull out the damaged washer and replace it with a matching size from your replacement parts.
- For Cartridges or Seals: If the cartridge or seal has worn out, remove it using pliers and install the new one carefully, aligning it as per the instructions.
- Tighten connections with a wrench, but avoid over-tightening as it can damage components.
Step 4: Clean the Valve and Faucet
Inspect and clean the valve seat inside the fixture to remove any mineral deposits that may affect performance. A simple brushing might prevent future issues.
Step 5: Reassemble the Faucet
Once you’re done replacing faulty parts, reassemble the handle and other components. Ensure everything is fitted properly to avoid gaps or loose connections.
Step 6: Test the Repair
Turn the main water supply back on. Slowly test both hot water and cold water to ensure the leak has stopped. Check for proper pressure while verifying there are no drips or problems.
