Buying Guide

Confirm your faucet type

Count the handles first. Single-handle faucets use one cartridge, while two-handle faucets may use one cartridge per side, so the part must match your setup.

Check the model series

Moen has produced many faucet series over the years. Look for the model number stamped on the faucet body or in the manual, and compare it to the listing before buying.

Decide between hot-side and full replacement

If only one side drips, a single-side cartridge can save time. If both sides leak or the handle feels stiff throughout, a full cartridge set is usually the better fix.

Prefer genuine parts

Listings marked as genuine Moen parts are generally a safer choice than unbranded substitutes, which owners sometimes report fit or seal problems with.

FAQ

How do I know which moen bathroom faucet cartridge replacement fits my faucet?

Find the model number on the faucet body or in the original manual, then compare it with the listing’s compatible series. When in doubt, a plumbing supply store can match the cartridge by sight.

Can I replace just one side of a two-handle faucet?

Often yes, if the cartridge is designed for a single side. Confirm the listing describes a hot or cold replacement before ordering.

Do I need to shut off water before swapping a cartridge?

Yes. Close the supply valves under the sink and open the faucet to relieve pressure. If you are unsure about the work, consult a licensed plumber.

Conclusion

For most two-handle bathroom faucets, the MOEN 1224 kit is a practical starting point. Single-handle faucets are better served by the Moen 1225 Magnum cartridge, while the Moen 1234 Duralast suits two-handle setups where only one side needs repair. Always confirm your model number before buying.
