How to Replace a Bathtub Faucet
Choose the New Faucet
The first step is picking out a replacement faucet that fits your bathtub and matches your bathroom’s decor. Here are some things to consider when selecting a new tub faucet:
- Style: Do you want a two-handle or single-handle model? Handles can be lever, cross, or knob style. Pick something that complements your existing hardware.
- Finish: Polished chrome and brushed nickel are popular neutral finishes. Oil-rubbed bronze and matte black offer a more modern look.
- Features: Look for anti-scald valves, pause functionality, high-arc spouts, and other useful features.
- Budget: Bathtub faucets range from about $50-500. Set a budget before you start shopping.
- Compatibility: Ensure the new faucet is designed to fit your existing tub and plumbing.
Once you’ve settled on the perfect faucet, purchase it from your local hardware store or order it online.
Gather the Required Supplies
Before starting the installation, you’ll need to gather the following supplies:
- Adjustable wrenches
- Basin wrench
- Teflon tape
- Plumber’s putty
- Flashlight
- Cloth
- Small bucket
- Faucet supply lines
- Screwdriver
Make sure you have all the necessary pieces that came with your new faucet as well, such as washers, gaskets, tubes, and installation hardware. Having all the right tools and parts on hand will make the installation process go much more smoothly.
Turn Off the Water Supply
The first step is shutting off the water supply to the existing bathtub faucet. This prevents water from spraying everywhere when you remove the old faucet. Here’s how to do it:
- Locate the shut-off valves – Usually under the sink or near the water heater.
- Close the hot and cold valves – Turn them clockwise all the way.
- Turn on the faucet – Double check the water is fully off.
- Open the tub spout – Allow any remaining water to drain out.
Once the water supply is successfully turned off, you can start removing the old faucet.
Remove the Old Bathtub Faucet
With the water off, it’s time to remove the existing bathtub faucet. Follow these steps:
- Disconnect and detach the supply lines – Loosen the coupling nuts that connect the supply tubes to the faucet. Remove the tubes.
- Remove the faucet handle – Use a screwdriver to take out the handle screw and lift off the handle.
- Unscrew the faucet cap – Twist off the decorative cap at the base of the spout.
- Unscrew the retaining nut – Use adjustable wrenches to loosen the large nut holding the faucet body in place.
- Lift out the old faucet – Rock it gently side-to-side while pulling up to remove it.
- Clean away old plumber’s putty – Scrape any remaining putty from the tub surface with a putty knife.
Now the tub area is prepped and ready for the new faucet installation.
Install the New Bathtub Faucet
It’s exciting time – the brand new faucet is ready to be installed! Follow these key steps:
- Apply plumber’s putty – Roll putty into a rope and place it around the faucet holes. This creates a watertight seal.
- Insert new faucet – Lower the new faucet into the faucet holes. Make sure it’s aligned properly.
- Hand tighten retaining nut – Tighten the retaining nut by hand first before using wrenches.
- Fully tighten retaining nut – Use adjustable wrenches to completely tighten the retaining nut.
- Attach supply lines – Connect the hot and cold supply lines to the faucet. Tighten the couplings with a wrench.
- Reattach handle – Line up the handle correctly and resecure it with the handle screw.
- Turn on water and test – Slowly turn on the shut-off valves. Check for leaks.
Be patient and take your time during installation to ensure everything is aligned and sealed properly.
Test the New Faucet
The exciting moment has arrived – it’s time to test your new bathtub faucet! Follow these steps:
- Turn water supply back on – Slowly turn on the shut-off valves to allow water back to the new faucet.
- Check for leaks – Inspect all connections for drips or leaks. Tighten as needed.
- Remove aerator – Unscrew and remove the aerator at the end of the spout.
- Flush the lines – Turn on both handles to full hot and full cold for 30-60 seconds.
- Clean out aerator – Rinse any debris from the aerator. Reattach it to the spout.
- Test faucet functions – Ensure hot and cold water runs properly. Check sprayer settings if applicable.
- Reinstall tub spout – Screw the tub spout back into place. Make sure it’s tightened fully.
- Caulk if needed – Run a bead of bathroom caulk around the faucet base if any gaps are visible.
That’s it – enjoy your sparkling new bathtub faucet!
