Moen application and cartridge record
Moen 1225 Cartridge for Single-Handle Bathroom Faucets
Moen identifies cartridge 1225 for single-handle bathroom faucet. Confirm the control layout, operating motion, and installed cartridge before buying; a similar-looking Moen trim is not proof of the valve or faucet beneath it.
Direct answer
The source-backed replacement relationship is single-handle bathroom faucet → Moen 1225. This is a reference match, not a promise based on appearance: Separate legacy 1225 applications from 1255 Duralast applications by checking the official model parts listing or the cartridge already installed.

What identifies this match
Use these details together. One matching feature does not establish compatibility.

- Referenced part
- 1225
- Source-backed application
- single-handle bathroom faucet

- One control regulates both discharge and mixed-water temperature.
Use motion as an identification clue, then verify the installed part.
Application relationship
Moen's product information places cartridge 1225 in the single-handle bathroom faucet application. That relationship is the reason this part is considered here; finish, handle shape, and escutcheon style are not compatibility evidence.
Treat this page as a focused identification record for the cartridge inside the control. The visible faucet or shower trim can be replaced while the underlying valve or faucet platform remains unchanged.
Identify the control before ordering
First confirm one handle controlling flow and temperature. Operate the control and check for this pattern: One control regulates both discharge and mixed-water temperature. A different motion points to a different Moen platform even when the trim looks close.
Then verify the generation or internal construction. Separate legacy 1225 applications from 1255 Duralast applications by checking the official model parts listing or the cartridge already installed. If documentation is available, use the model number and its official parts diagram rather than a photo-only match.
What the match does not establish
A one-handle lavatory faucet is not automatically a 1225 application; 1255 is another official Moen single-handle faucet cartridge. Moen has used more than one cartridge family across products with broadly similar silhouettes, so brand and handle count alone do not settle the choice.
Do not transfer this relationship to another fixture category without an official parts listing. The exact number on the package should match the verified replacement number, including every digit.
Removal-side confirmation
Shut off the appropriate water supplies and relieve pressure before exposing the cartridge. Photograph handle orientation and retaining hardware as each piece comes off; those details help preserve the original setup.
Compare the removed cartridge's body, stem, seals, and retention method with Moen's official material. If the old part is damaged or incomplete, stop and identify the faucet or rough-in valve from its markings instead of guessing from the fragment.
Questions
Before you remove or replace the part
Does every single-handle bathroom faucet use Moen 1225?
No blanket fit claim is intended. Moen supports the stated application relationship, but revisions and similarly named products make model, motion, and installed-part checks important before purchase.
Can I identify the cartridge from the handle style?
Not reliably. Handle style is a screening clue only. Confirm one handle controlling flow and temperature, the operating motion, and the cartridge or valve documentation.
Should I remove the old cartridge before buying?
When the model or valve platform cannot be documented another way, removal-side inspection is the strongest check. Shut off water first and preserve the orientation and retaining pieces for reassembly.
