When the shower valve is installed, it will have a set position in the shower.
This is based on the original rough-in and where the shower valve is supposed to go. Unfortunately, this does not control how deep a shower valve is installed once it’s put in.
You will have to figure out how to fix a shower valve that’s too deep in the wall.
If a shower valve is too deep in the wall, use a shower valve extender. This goes between the base and the valve offering a couple of inches of added length.
In some cases, you will have to strip the shower valve off and install a new unit. This is if you can’t find a compatible shower valve extender that is going to work for your fixture.
It’s highly recommended to use the extender as it will be an easy fix and is going to provide the right amount of length without compromising the style of your shower valve.
This guide will explain how to fix a shower valve that’s too deep in the wall and what to use during the change.

Steps To Fix A Shower Valve Too Deep In Wall
1. Take Measurements
If a shower valve is too far back, it needs to be corrected.
This will make the shower valve unusable and that’s the last thing you are going to want as a property owner.
To fix the issue, start with a bit of research.
This includes taking out a measuring tape and seeing what the current measurements are. You will want to check how big the shower valve is, how high it is off the ground, and how much it’s sticking out right now.
This is key information that will allow you to find a good shower valve extension that is going to work as well as you want it to.

2. Find Compatible Shower Valve Extension
Once you have the necessary measurements and desired length, it’s time to go on the hunt for a compatible shower valve extension.
Please note that there is no such thing as a universal shower valve extension.
Each brand has its selection of valve extensions and you will need to find the one that works for your specific model. Whether it’s Moen, Delta, or any other brand, go through and get the model number.
You will need this information to make sure the shower valve extension is a perfect fit. The leading brands do offer a wide array of extensions, so it’s more of a matter of finding what you need.
Go through and find an original part to ensure it’s a perfect fit.
3. Tighten The Shower Valve
With the shower valve extension in hand, it’s time to tighten the shower valve carefully.
To do this, you are going to want to set the extension into place, put the valve on top, and then tighten everything.
Make sure nothing will budge and the base of the valve has not moved. The extension should only focus on the handle rather than any other part of the valve.

4. Replace The Valve (If Extension Doesn’t Work)
Let’s assume you can’t find a compatible shower valve extender.
What is going to happen then?
You are not straight out of luck. Instead, it comes down to finding a different way to tackle this problem.
With your situation, it’s best to take the same measurements from before and replace the valve with a completely new part. The idea here is to get a shower valve that will naturally stick out more.
This will save you a lot of trouble and set the valve into place without needing an extension.
In many cases, this is the only way forward since they can’t find the model number or the right extension. If so, this is a good option and will change the valve too.
Final Thoughts
These are the best choices available to you if a shower valve is too deep in the wall.
When a shower valve is too deep in the wall, it’s time to buy a compatible extension. The extension is installed between the base and the handle. It will add 2-3 inches in length on top of the existing valve.
This is a simple fix and most brands will have compatible parts sold through different stores or online.
Look for your specific model number and ensure it’s the right fit.
Once you do this, the shower valve is going to work like a charm and look good too.
