Using a pipe wrench or large adjustable pliers, carefully grip the threaded bonnet nut that holds the valve cartridge in place. Turn it counter-clockwise to loosen and remove it completely. Once the nut is off, you can simply lift the old valve cartridge straight out of the faucet body. Have a rag ready as some residual water will spill out.
Goal: Remove the old valve cartridge

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.
