Roman Tub Faucet: Identifying a Deck Mount Faucet Cartridge

Preparation:  The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the Faucet.

Step 1: Do I Have A Garden Tub Or A Roman Tub Faucet?

Moen makes two basic types of soaking tub faucets- roman tub faucets and garden tub faucets. These faucets are identical in appearance however the spouts for garden tub faucets are shorter than spouts for roman tub faucets. See the spout length chart below for the collections that are available in both roman tub and garden tub options. Garden tub faucets and valves began transitioning from the 14891 cartridge to the 1224 cartridge in 2000. It is important to verify that you have a garden tub because the cartridges are not interchangeable.

Step 2: Identifying The Cartridge
 If you are going to remove the cartridge, the water supply shutoffs must be turned off before beginning.
There are four different cartridges that are used in deck mounted tub faucets and valves. Due to the fact many faucets come as trim kits and separate valves, it is possible to have a new trim kit on an older valve making identifying the cartridge difficult.
