There are multiple cartridges used on Roman Tub faucets. Confirming which one you are working with will require removing the handle and identifying your handle mechanism. If these requirements have not yet been confirmed, see Roman Tub Deck Mount: Lever or Roman Tub Deck Mount: Knob for details at solutions.moen.com.

For additional details, visit Roman Tub Deck Mount: Lever or Roman Tub Deck Mount: Knob and select the type you are repairing.
