If you follow these steps, replacing your roman tub faucet will be quick and easy!

Step 1: Shut Off Water Supply

Shut off your home’s main water supply valve. It is typically located near your water meter and can be identified by a blue handle with shut-off markings.

 If you do not access your main water valve, shut off all valves leading to your tub or shower. These valves usually located in basement or crawl space near where your pipe comes into the house and should be identifiable with white handles with shut-off markings.

Step 2: Remove Handle and Pop-Up Drain

Remove the handle and pop-up drain. If you’re having difficulty with any of these steps, it’s best to seek professional help from a licensed plumber.

Step 3: Add New Pop-Up Drain

Use an adjustable wrench and loosen all three nuts around your pop-up tub drain. You may need to use pliers if they are particularly tight. The nut that holds down your pop-up stopper is often located on top of your sink between two handles or under one of them. Pull up on the stopper and remove it from its seat in your drain pipe.

Step 4: Attach New Bathtub Spout

The final step in replacing your roman tub faucet is attaching your new bathtub spout. This can be done with pipe tape, Teflon tape or glue. 

Step 5: Turn On Water Supply

Before you remove your old faucet:

  1. Turn on your water supply.
  2. Make sure it is working properly, and there aren’t any leaks where it connects to your plumbing.
  3. If there are leaks, turn off your water supply and contact a plumber immediately.

This can be expensive if you are not familiar with how to fix it yourself. It is also hazardous because you might flood your bathroom or basement floor. Take care of these issues before removing your old faucet.


In most cases, unless you have easy access to your roman tub faucet’s inner workings, it will be best and safest if you hire a professional. This may cost some extra money upfront, but it could cost even more in terms of time and headaches if you end up damaging something.

 If you do decide to go for it yourself, make sure you know what you’re doing before attempting to replace a roman tub faucet. If not, there are plenty of online information resources that can help walk you through each step so that your replacement goes smoothly and without incident. 


Is the Roman tub faucet interchangeable?

While you must know how to replace roman tub faucets in case one breaks or becomes damaged, you must also have some idea of what makes them different from other kinds of tub faucets.

How do we make an invisible access panel?

Making an invisible access panel is easy if you have one piece of information: where your main water supply enters your home. Once you know where that spot is, cut a small hole through it (with water off, of course) and feed in two plastic lines that’ll connect to your new faucet. 

Connect those lines and use them to route hot and cold water into your tub, and then switch them when replacing old lines with new ones.

How Do I Know If I Need To Replace My hot tub Faucet Cartridges?

If you think your faucets are leaking, but they aren’t dripping, it may be time to replace your faucet cartridges. But how do you know if you should replace just one or both? You might not have any water coming out of your sink, shower, or tub.

 This could mean that there is no hot water coming out of any of these fixtures and that you need to replace all three cartridge types for them to work properly again. 

Another common sign that it’s time for new cartridges is when water starts spraying out from under your tub instead of running through pipes and into your bathtub or shower.

If you’re looking for something different from what’s already in place, plan to spend anywhere from $50 to $200 or more. Most people spend between $100 and $150 for a standard tub/shower combination.
