How to Replace a Roman Tub Faucet (Guide for No Access Panels)

Replacing a roman tub faucet can be difficult because they do not have a traditional access panel like other kinds of faucets.

Nevertheless, here is a comprehensive step-by-step guide on how to replace a Roman tub faucet.

Here is a quick list of the tools that you will need for the job:

  • Flathead or Phillips screwdriver
  • Adjustable wrench
  • Cloth/rag
  • Hex/Allen wrench
  • Putty knife and plumber’s putty (optional)
  • New faucet kit

Step 1. Remove the Existing Faucet

The first noticeable thing to do is remove the existing faucet. First, turn off the water supply to the area entirely and remove handle cover plates (if any).[2]

You will also want to make sure that you cover any drains so that small pieces do not slip away from you and down them.

Most of the time, you can remove the faucet using hex wrenches which are likely hidden.

Next, remove the faucet fixture by pulling up and removing the handles. Remove any leftover putty on the bottom to make sure the base is clean. Also, make sure that you place all the hex screws and bolts in a safe place.

Next, apply any plumber’s putty if necessary. Place the new handles over the existing cartridges and slide the new spout over the spout pipe, taking great care to make sure the pipes line up correctly. Tighten any and all hex screws.

Step 3. Test It

Next, it’s time to test the faucet to make sure it is working. Turn the water supply back on and test out the faucet at different levels of activation, including hot and cold each separately.

Make sure that there are no leaks, or else you will need to retighten the faucet.

From there, your bathtub is good to go.
