How to Replace a Bathtub Faucet: A Step-by-Step DIY Guide · Step 5 of 6
This DIY guide provides step-by-step instructions for replacing a bathtub faucet. The project begins by removing the faucet handles, often by unscrewing a cap or using an Allen wrench. Next, turn off the water supply by locating the shut-off valves under the sink and turning them clockwise. If there are no shut-off valves under the sink, you'll need to turn off the main water supply to your house. After the water is off, remove the escutcheon plate, the decorative cover surrounding the faucet, typically held in place by screws. With the escutcheon plate removed, the old faucet body can then be carefully removed, usually secured with nuts that can be loosened with an adjustable wrench. Once the old faucet body is out, the new faucet body can be installed following the manufacturer's instructions. This step usually involves applying plumber's putty to the base, inserting the faucet body, and tightening the nuts from below. Finally, reinstall the escutcheon plate, handles, and any decorative trim. Turn the water supply back on slowly and check all connections for leaks. Tighten any loose connections and retest for leaks to ensure a proper seal.

FAQs
Is replacing a bathtub faucet truly a beginner-friendly DIY project, and what's a realistic time frame for completion?
Yes, it's generally considered beginner-friendly, especially with clear instructions. While estimated at 3 hours, allow for extra time if you encounter rusted parts or need to locate the main water shut-off. Patience is key for a successful first-time installation.
Beyond basic screwdrivers, what are the most crucial tools for this bathtub faucet replacement that I might not already own?
An adjustable wrench is essential for loosening and tightening nuts, while plumber's putty is critical for creating a waterproof seal. You might also find a basin wrench helpful if working in very tight spaces, though not always strictly required for all faucet types.
What should I do if I can't find individual shut-off valves for my bathtub faucet, or if they don't work?
If local shut-off valves are absent or faulty, you must turn off the main water supply to your entire house. After turning off the main supply, open a faucet on the lowest level of your home to drain any remaining water from the pipes before proceeding with the replacement.
What is the most common mistake that leads to leaks after installing a new bathtub faucet, and how can I prevent it?
The most common mistake is not fully tightening all connections or improperly applying plumber's putty. Ensure all nuts are snug (but don't overtighten) and that plumber's putty forms a complete, even seal around the faucet base. Always test slowly after turning water back on and inspect thoroughly for drips.
