Before embarking on this plumbing adventure, it is crucial to meticulously gather an arsenal of essential tools and materials:

Adjustable wrench or basin wrench
Phillips screwdriver
Allen wrench (if required)
Replacement Moen bathtub faucet cartridge
Plumber's putty (optional)

Step-by-Step Guide:

Turn Off Water Supply: Begin by closing the water supply valves situated beneath the sink. If your bathtub lacks accessible valves, locate and shut off the main water supply to your residence.
Remove Handle: Utilize a Phillips screwdriver to cautiously detach the handle from the faucet. Concealed beneath the handle is a small screw that must be removed.
Unscrew Cartridge Nut: Employ an adjustable wrench or a basin wrench to loosen and remove the cartridge nut. It may be concealed by a decorative cap, which must be carefully pried off.
Extract Old Cartridge: Gently grasp the old cartridge and pull it directly towards you to extract it from the faucet body. If the cartridge is particularly stubborn, you may need to employ a pair of pliers.
Apply Plumber's Putty (Optional): To enhance the watertight seal, apply a thin layer of plumber's putty around the base of the new cartridge. This step is optional but highly recommended.
Insert New Cartridge: Align the new cartridge with the faucet body and carefully insert it by pushing it straight in until it is firmly seated. Ensure that the cartridge is properly oriented.
Secure Cartridge Nut: Hand-tighten the cartridge nut onto the faucet body as much as possible. Subsequently, utilize the adjustable wrench to further tighten the nut, ensuring that it is adequately snug but not excessively overtightened.
Reinstall Handle: Reposition the handle onto the faucet and secure it using a Phillips screwdriver. Tighten the screw firmly to prevent any subsequent movement.
Turn On Water Supply: Slowly turn on the water supply valves situated beneath the sink or, if inaccessible, the main water supply to your residence. Inspect for any leaks around the cartridge and promptly address any if necessary.

Congratulations! You have successfully replaced the Moen bathtub faucet cartridge, restoring your faucet to its former glory. If you encounter any difficulties or uncertainties during the process, do not hesitate to seek professional assistance from a qualified plumber.
