When do you Want to Change Your Bathtub Faucet?

There are a few common reasons you may decide it’s time to replace your tub’s faucet:


Updating the Style

One of the top motivators for changing a bathtub faucet is simply to update the style. Over years of use, faucets can start to look dated. Replacing your faucet with a more modern style can make your bathroom feel brand new.

Popular style trends right now include minimalist, geometric shapes for a contemporary vibe. Or go for an ornate, vintage look with clear acrylic knobs and cross handles if you want a traditional feel. The options are endless, so changing the faucet is an easy way to match the latest trends.

Fixing Leaks

If you notice your faucet is leaking, it likely means parts are worn out. Sometimes you can fix leaks by replacing rubber washers or O-rings, but often the damage is extensive enough that the entire faucet needs replacement. Dealing with a leak quickly is important to prevent mold or water damage. Replacing the faucet solves the problem at the source.

Improving Flow

Older bathtub faucets often have a flow rate of 2.5 gallons per minute (GPM) or more. Newer models are required to be 1.5 GPM or less. Switching to a lower-flow faucet conserves water and can reduce your bills. Low flow faucets still have enough pressure for comfortable bathing and look sleek too.

Choosing a New Bathtub Faucet

Once you decide to tackle a bathtub faucet replacement, your first step is picking out the new fixture. Here are key factors to consider:


As mentioned earlier, the style you select can totally change the vibe of your bathroom. Go for a classic polished chrome look or perhaps something more unusual like black, bronze, or brushed nickel. Match the finish on your faucet handles to other fixtures in the room.

Also think about the visual style and shapes that appeal to you. Do you want something sleek and minimalist or quirky and retro? Look for a style that suits your tastes.


You don’t want to have to replace your brand new faucet in just a few years. Seek out high-quality models from reputable manufacturers like Kohler, Delta, Moen, or American Standard. Check reviews to ensure the faucet doesn’t have widespread complaints about leaks or other flaws. Paying a little more upfront is worthwhile.

Ease of Installation

Some faucets are designed to make DIY installation simpler, like those with supply lines that connect via quick connect couplers rather than nuts and washers. If you’re new to plumbing, look for an easy-install model. We’ll go over more faucet replacement tips coming up.

Flow Rate

To conserve water, look for an EPA WaterSense certified low flow faucet. These are required to have a flow below 1.5 GPM. You’ll still get solid water pressure, just use less water.


Bathtub faucets can range from about $80 on the low end to $500+ for high-end designer models. Set a reasonable budget based on your needs and stick to faucets in your price range.

Getting Ready for Installation

Replacing a bathtub faucet requires some advance preparation to ensure things go smoothly. Follow these tips before starting:

Gather Supplies

You’ll need some basic tools and materials:

  • Adjustable wrenches
  • Basin wrench for tight spaces
  • Plumber’s putty
  • Pipe tape
  • New supply lines
  • Teflon tape
  • Flashlight
  • Cloth rags
  • Bucket

Make sure you have everything on hand before turning off the water and removing the old faucet.

Shut Off Water Supply Lines

Locate the shut-off valves for the hot and cold water lines under or near your tub and turn them clockwise to shut off the water. Turn on the tub faucet briefly to release pressure. Disconnect and drain the supply lines.

Read the installation instructions.

Each faucet comes with specific installation instructions. Read them thoroughly so you understand each step before you begin. Make sure to follow the directions closely during installation.

Clear the Sink Area

Remove everything from under the sink or tub area so you have ample room to work. Lay down towels or drop cloths to catch drips or spills. Having an uncluttered workspace makes a big difference for this project.

Okay, the prep work is done, and you’re ready to remove the old faucet!

Removing the Old Bathtub Faucet

Start by taking apart your existing faucet assembly piece by piece:

Remove Faucet Handle

Use a screwdriver to detach the handle. You may need to pry off a decorative cap first to access the screw. Place parts in a bag to keep track of them.

Detach Spout

Unscrew the retaining nut holding the spout in place. You may need a basin wrench for leverage. Pull out the spout.

Remove Valve Stems

Use adjustable pliers or a wrench to take out the hot and cold valve stems. Take note of which is hot vs. cold. Remove any remaining parts attached to the tub such as escutcheon plates.

Clean Away Old Putty

Scrape off any remaining putty residue with a putty knife. Wipe the area clean with a damp rag.

With all the old faucet pieces removed, the tub area is now prepped and ready for the new faucet.

Installing the New Faucet

It’s time for the fun part – installing your beautiful new bathtub faucet! Follow these key steps:

Prepare Supply Lines

Attach the flexible supply lines to the new faucet, making sure hot lines up with hot side and cold with cold. Use Teflon tape on threads to prevent leaks.

Position Faucet

Set the new faucet into place on the tub. Ensure the base is centered and sits flat. Outline the base with plumber’s putty.

Secure Faucet

Place the gasket and mounting bracket below the tub if included. Reattach supply lines. Hand tighten couplings, then finish tightening with wrench. Don’t overtighten.

Attach Spout

If the spout is a separate piece from the valves, slide it into place and secure with retaining nut. Ensure it’s aligned properly.

Install Valve Stems and Handles

Insert new valve stems into hot and cold ports, making sure rubber seats fit properly. Thread on handles and bonnet nuts. Attach index button or cap if included.

Make Final Connections

Connect supply lines to shut-off valves. Turn on hot and cold water and check for leaks during operation. Tighten any leaky connections.

Seal with Putty

Once all connections are secure, seal around the new faucet with plumber’s putty to prevent water getting under tub. Wipe away any excess smoothly.

Be sure to test the new faucet for leaks and proper flow. Once that’s done, you can handle some finishing touches.

Completing the Project

To complete your bathtub faucet replacement, just a few small tasks remain:

Remove Debris

Carefully remove any putty or other debris left over from the installation process. Wipe down the exterior of the new faucet with a clean damp cloth to remove dust.

Re-caulk if Needed

If any of the existing caulk around the tub is damaged, you may want to re-caulk those areas smoothly for a finished look. Let dry completely.

Check Water Pressure

Test the hot and cold water pressure and adjust if needed. Ensure ample flow for comfortable bathing. Turn faucet on and off several times and check below for drips.

Flush the Lines

Finally, turn on the hot and cold taps and let the water run for a minute or two to flush out any sediment in the lines. The initial flow may look discolored – this is normal.

With that, your new bathtub faucet makeover is complete! Take a moment to appreciate how a simple upgrade like this can make your bathroom feel brand new.
