Your shower knob may need to be removed for a variety of reasons. Perhaps you’re remodeling your bathroom and want to update the fixtures, or maybe the knob has become loose or damaged and needs to be replaced. Whatever the reason, removing a shower knob is a relatively simple task that you can do yourself with just a few basic tools.
Before you begin, it’s important to gather the tools you’ll need. You’ll need a Phillips head screwdriver, an Allen wrench, and a pair of pliers. Once you have your tools, you can begin the process of removing the shower knob.
First, you’ll need to remove the handle from the knob. To do this, simply unscrew the Phillips head screw that is located in the center of the handle. Once the screw is removed, the handle will come off easily.
Next, you’ll need to remove the retaining nut that is located behind the handle. To do this, use the Allen wrench to loosen the nut. Once the nut is loose, you can remove it by hand. With the retaining nut removed, you can now pull the knob off of the valve stem. If the knob is stuck, you can use the pliers to gently pry it off.
Locating the Set Screw
Identifying the set screw is crucial for successful shower knob removal. While most shower knobs feature a single set screw, some models may have two. Locate the set screw by carefully examining the surface of the knob. It is typically a small screw, often concealed by a cap or button.
In most cases, the set screw is situated in the center of the knob. Look for a tiny hole or indentation, which is often disguised by a plastic or metal cap. This cap may be pryed off using a flathead screwdriver or your fingernails.
If the set screw is not visible in the center of the knob, it may be located under a small plastic tab or lever. Gently lift or slide the tab to reveal the set screw underneath. Occasionally, the set screw is hidden behind a decorative cover, which can be unscrewed or pried off to grant access to the screw.
Consult the following table for a quick guide on locating the set screw based on the type of shower knob you have:
| Knob Type | Set Screw Location |
|---|---|
| Single-Handle Knob | Center of the knob, under a cap or button |
| Dual-Handle Knob | Under a small plastic tab or lever |
| Decorative Knob | Behind a decorative cover that must be removed |
Removing the Set Screw
Removing the set screw is the first step in taking apart a shower knob. It’s usually located on the side of the knob, near the base. You’ll need a small Allen wrench or hex key to remove it.
Here are the steps on how to remove the set screw:
1. Find the set screw
It’s usually located on the side of the knob, near the base. It’s a small screw, and may be difficult to see if it’s covered in grime or mineral deposits.
2. Insert the Allen wrench or hex key
The size of the Allen wrench or hex key you need will depend on the size of the set screw. Insert the wrench into the set screw and turn it counterclockwise to loosen it.
3. Remove the set screw
Once the set screw is loose, you can remove it by hand. Be careful not to lose the screw, as you’ll need it to reassemble the knob later.
If the set screw is stuck, you can try using a pair of pliers to loosen it.
| Tool | Description |
| Allen wrench or hex key | A small tool used to loosen and tighten set screws. |
| Pliers | A tool used to grip and turn objects. |
Unscrewing the Cap or Handle
In many cases, the shower knob is secured by a cap or handle that needs to be removed before you can access the screws. Here’s how to do it:
1. Check the knob for a small hole
Some shower knobs have a small hole on the face of the knob. If your knob has this hole, insert a small Allen wrench or hex key into the hole and turn it counterclockwise to loosen the cap or handle.
2. Use a flathead screwdriver
If there is no hole, use a flathead screwdriver to pry off the cap or handle. Carefully insert the screwdriver into the seam between the cap or handle and the knob and gently pry it off. Be careful not to damage the knob or the surrounding tiles.
3. Using Pliers
If the cap or handle is particularly tight, you may need to use pliers to remove it. Wrap a cloth around the cap or handle to protect it from scratches, then use the pliers to gently twist and pull the cap or handle off. Again, be careful not to damage the knob or the surrounding tiles.
| Method | Tools Needed |
|---|---|
| Using an Allen wrench | Small Allen wrench or hex key |
| Using a flathead screwdriver | Flathead screwdriver |
| Using pliers | Pliers, cloth |
Accessing the Locking Nut
In most cases, the locking nut can be accessed from behind the shower panel. However, if you are unable to reach the nut from behind, you may need to remove the trim plate that surrounds the shower knob. To do this, insert a screwdriver into the notch located on the edge of the trim plate and gently pry it off.
Once the trim plate is removed, you should be able to see the locking nut. It is usually a large, round nut that is located in the center of the shower knob. Use a wrench or pliers to loosen the locking nut and remove it from the shower knob.
If you are having difficulty loosening the locking nut, you can try applying a penetrating lubricant to the nut. Allow the lubricant to sit for a few minutes before attempting to loosen the nut.
If you are still unable to access the locking nut, you may need to call a plumber for assistance.
Tools You Will Need
| Tool | Description |
|---|---|
| Screwdriver | Used to pry off the trim plate |
| Wrench or pliers | Used to loosen and remove the locking nut |
| Penetrating lubricant | Optional, used to loosen rusted or seized nuts |
Loosening the Locking Nut
The locking nut is usually located behind the shower knob. It holds the knob in place and prevents it from coming loose. To loosen the locking nut, you will need a pair of adjustable pliers or a wrench.
1. Turn off the water supply to the shower. This will prevent water from leaking out when you remove the knob.
2. Place the pliers or wrench around the locking nut and turn it counterclockwise. The locking nut may be tight, so you may need to apply some force.
3. Once you have loosened the locking nut, you can remove the shower knob. To do this, simply pull the knob straight towards you.
4. If the knob does not come off easily, you may need to use a screwdriver or a putty knife to pry it loose.
5. Once the knob is removed, you can see the shower valve stem. The valve stem is what controls the flow of water to the shower head. If you need to replace the valve stem, you can do so now. To remove the valve stem, simply unscrew it from the shower body.
Disconnecting the Cartridge
6. Remove the cartridge using pliers or a special tool (if applicable):
| Cartridge Type | Removal Tool |
|---|---|
| Standard compression cartridge | Pliers |

| Thermostat cartridge | 専用 Tool |
**Additional Details:**
- For standard compression cartridges: Use pliers to hold the cartridge by the slots or notches on its outer surface. Twist it counterclockwise to loosen and remove it.
- For single-handle cartridges: Consult the manufacturer’s instructions for the specific tool required. These tools usually have a special shape or prong design to engage with the cartridge’s locking mechanism.
- For thermostat cartridges: Similar to single-handle cartridges, a専用のtool is typically required. Follow the manufacturer’s instructions carefully to avoid damaging the cartridge or internal components.
Tips:
- If you encounter difficulty removing the cartridge, apply a penetrating oil or lubricant to the locking mechanism and let it sit for a few minutes before attempting to turn it.
- Use caution when handling the cartridge to avoid damaging its internal components.
- If you are not comfortable removing the cartridge yourself, it is recommended to call a qualified plumber for assistance.
