Updating the shower valve is one of the most common plumbing projects DIYers tackle. But if you’ve never done it before, the task can seem daunting. Moreover, a faulty shower valve can lead to several issues, including leaks, dripping water, and even scalding. In this article, we’ll walk you through the steps on how to install a shower valve like a pro. Whether you’re a complete novice or have some plumbing experience, our detailed instructions and tips will guide you through the process smoothly. So, grab your tools, and let’s get started!
Before you begin, it’s crucial to gather the necessary tools and materials. You’ll need a new shower valve, a pipe wrench, a screwdriver, pliers, Teflon tape, and a level. Additionally, you may also need to purchase new shower trim, depending on the style of your new valve. Once you have everything you need, turn off the water supply to your shower and remove the old valve. Be sure to catch any water that may drain from the pipes.
Now it’s time to install the new valve. First, wrap the threads of the valve body with Teflon tape. This will help to create a watertight seal. Then, screw the valve body into the shower wall. Be sure to tighten it securely, but don’t overtighten it. Next, connect the water supply lines to the valve body. Again, use Teflon tape on the threads to ensure a good seal. Finally, install the shower trim and handle. Turn on the water supply and check for leaks. If you see any leaks, tighten the connections until they stop. And that’s it! You’ve successfully installed a new shower valve.

Remove Old Shower Valve
Before you begin installing your new shower valve, it’s important to remove the old one. Here’s how to do it:
1. Turn off the water supply.
The first step is to turn off the water supply to your shower. This will prevent any water from leaking out while you’re working.
2. Remove the trim plate.
Once the water is turned off, you can remove the trim plate around the shower handle. This is usually held in place by screws or clips.
3. Remove the cartridge or stem.
Disconnect the water supply lines.
Remove the valve body.
The next step is to remove the cartridge or stem inside the valve body. This is what controls the flow of water. The type of cartridge or stem you have will vary depending on the type of shower valve you have.
Once the cartridge or stem is removed, you can disconnect the water supply lines from the valve body. These are usually held in place by nuts or compression fittings.
Finally, you can remove the valve body itself. This is usually held in place by screws or bolts.
| Tool Required |

| Screwdriver |
| Wrench |
| Pliers |
Connect Water Supply Lines
The first step is to connect the water supply lines. This can be done with either PEX tubing or copper pipe. If you are using PEX tubing, you will need to use a crimp tool to attach the fittings. If you are using copper pipe, you will need to use a soldering iron to solder the pipe to the fittings. Make sure that the connections are tight and that there are no leaks.
Once the water supply lines are connected, you can begin to install the valve. The valve should be installed according to the manufacturer’s instructions. Generally, the valve will be installed between the two water supply lines. The valve body will have two inlets and one outlet. The inlets will be connected to the water supply lines, and the outlet will be connected to the shower head.
When installing the valve, it is important to make sure that it is level. This will help to ensure that the water flows evenly through the valve. You should also make sure that the valve is securely fastened to the wall. This will help to prevent the valve from leaking.
Materials Needed
| Item | Quantity |
|---|---|
| PEX tubing or copper pipe | As needed |
| Crimp tool (if using PEX tubing) | 1 |
| Soldering iron (if using copper pipe) | 1 |
| Valve | 1 |
Secure Shower Valve
After installing the shower valve body, you’ll need to secure it in place. This will prevent it from moving or leaking once it’s in use. Here are the steps on how to secure a shower valve:
- Apply a bead of silicone caulk around the base of the shower valve body.
- Screw the mounting nuts onto the valve body. Tighten them until they’re snug, but don’t overtighten them.
- Apply a second bead of silicone caulk around the top of the shower valve body.
- Install the shower valve trim. The trim will typically consist of a handle and a faceplate.
- Tighten the screws that secure the trim to the valve body.
- Turn on the water supply to the shower and check for leaks.
If you find any leaks, tighten the mounting nuts or apply more silicone caulk until the leak stops.
Tips for Securing a Shower Valve
- Use a level to make sure that the shower valve body is installed level.
- Don’t overtighten the mounting nuts. Overtightening can damage the valve body or the mounting nuts.
- Apply a generous bead of silicone caulk to ensure a watertight seal.
- Allow the silicone caulk to cure completely before using the shower.
