Remodeling your bathroom can be a daunting task, but it doesn’t have to be. One of the most common upgrades is replacing the shower knob, and it’s a relatively easy project that can be completed in a few hours. In this article, we’ll walk you through the steps of how to remove a shower knob so you can get started on your bathroom remodel.
Before you begin, you’ll need to gather a few tools. You’ll need a Phillips head screwdriver, a flat head screwdriver, and a pair of pliers. You may also want to have a towel or cloth on hand to catch any water that may leak out when you remove the knob.
Once you have your tools gathered, you can start the removal process. First, turn off the water to the shower. This is usually done by turning off the valve under the sink. Once the water is turned off, you can remove the faceplate of the shower knob. This is usually held in place by a few screws. Once the faceplate is removed, you’ll see the screws that hold the knob in place. Remove these screws and the knob will come off.
Identifying the Type of Shower Knob
Your shower knob is the control center of your showering experience, allowing you to adjust temperature and water flow. But before you can remove it for repair or replacement, you need to identify its type. Here’s how:
1. Screw-On Knobs
Screw-on knobs are the most common type. They are typically round or square, and they have a threaded stem that screws into the shower valve. To identify a screw-on knob, look for a small hole in the center of the knob. If there is a hole, it is most likely a screw-on knob.
Here’s how to further identify a screw-on knob:
- Examine the material: Screw-on knobs are typically made of plastic, metal, or ceramic.
- Check the knob’s shape: Screw-on knobs can be round, square, or octagonal.
- Identify any decorative elements: Screw-on knobs may have ridges, knurling, or other decorative details.
| Feature | Description |
|---|---|
| Material | Plastic, metal, or ceramic |
| Shape | Round, square, or octagonal |
| Decorative elements | Ridges, knurling, or other details |
Gathering Necessary Tools and Materials
Before you begin, it is crucial to gather the necessary tools and materials to ensure a smooth and safe process. Here’s a detailed breakdown of what you will need:
Essential Tools:
| Tool | Purpose |
|---|---|
| Allen wrench or hex key | For removing the set screw holding the knob |
| Phillips head screwdriver | For unscrewing the faceplate (if applicable) |
| Adjustable wrench or pliers | For gripping and loosening the knob itself |
Optional but Useful Items:
While not strictly necessary, these items can make the process easier and more efficient:
- Towel or rag: To wrap around the knob for better grip and prevent scratches
- Penetrating oil or WD-40: To lubricate stuck or rusted components
- Flashlight or headlamp: For providing adequate lighting in tight spaces
- Needle-nose pliers: For removing small parts and retrieving dropped screws
- Replacement knob and any necessary hardware: If you are replacing the knob, ensure you have the correct size and type
Removing the Faceplate or Handle
Begin by inspecting the shower knob to determine how it is secured. Most shower knobs are held in place by a screw or a set screw. If your shower knob has a screw, it will be located in the center of the faceplate or handle. If your shower knob has a set screw, it will be located on the side of the faceplate or handle.
Removing a Screw
To remove a screw, you will need a screwdriver that is the correct size. Once you have the correct screwdriver, insert it into the screw and turn it counterclockwise. The screw should come out easily.
Removing a Set Screw
To remove a set screw, you will need a hex key that is the correct size. Once you have the correct hex key, insert it into the set screw and turn it counterclockwise. The set screw should come out easily.
Removing the Faceplate or Handle
Once you have removed the screw or set screw, you will be able to remove the faceplate or handle. To do this, simply pull the faceplate or handle straight towards you. The faceplate or handle should come off easily.
Removing the Valve Cartridge
Once you have removed the faceplate or handle, you will be able to access the valve cartridge. The valve cartridge is a cylindrical-shaped component that controls the flow of water in and out of the shower. To remove the valve cartridge, you will need a pair of pliers.
| Tool | Use |
|---|---|
| Screwdriver | Remove screw |
| Hex key | Remove set screw |
| Pliers | Remove valve cartridge |
Using a Hex Key to Remove the Screw
Grab the hex key or Allen key that fits the screw. You may need to try different sizes until you find the one that fits snugly. Hex keys are typically L-shaped tools with a hexagonal-shaped end that inserts into the screw. Ensure that the hex key’s end is the correct size to fit the screw without any wobble. If the wrong size is used, it can damage the screw or round it off, making it harder to remove.
Insert the short arm of the hex key into the screw. The short arm is usually used for better control and leverage while turning the screw. Position the hex key perpendicular to the screw to avoid stripping the head.
Apply pressure to the hex key and turn it counterclockwise. Turn the screw slowly and steadily to avoid stripping the screw head. Use short, controlled turns to ensure you’re applying the force in the right direction. If the screw is particularly tight, you might need to use a pair of pliers to provide extra grip on the hex key.
Once the screw is loose, you can pull it out by hand. Grip the exposed part of the screw with your fingers and gently pull it towards you. If it’s still stuck, you can use a pair of needle-nose pliers to grip the head and pull it out.
In some cases, the screw may be so corroded or damaged that it can’t be removed using a hex key. If this happens, you may need to use a screw extractor. Screw extractors are designed to grip the damaged screw and allow you to remove it. Consult the instructions provided with the screw extractor for specific directions on how to use it.
| Hex Key Size: | Choose a hex key that fits the screw snugly. |
| Screw Insertion: | Insert the short arm of the hex key into the screw perpendicularly. |
| Turning Direction: | Turn the screw counterclockwise slowly and steadily. |
| Screw Removal: | Once loose, pull the screw out by hand or with pliers. |
Separating the Knob from the Stem
Once the set screw is loosened or removed, you can separate the knob from the stem. Here’s how to do it safely and effectively:
1. Protect Your Hands
Wear gloves to protect your hands from any sharp edges or hot water.
2. Grip the Knob Firmly
Grab the knob with a towel or cloth to prevent slipping and protect your hands from heat.
3. Pull Straight Back
Grasp the knob firmly and pull it straight back toward you. Do not twist or wiggle the knob, as this could damage the stem.
4. Remove the Knob
Once the knob is pulled back far enough, it should come off the stem. If it doesn’t come off easily, gently tap the back of the knob with a hammer to loosen it.
5. Inspect the Stem
Once the knob is removed, inspect the stem for any damage or corrosion. If the stem is damaged, you may need to replace it before installing a new knob.
6. Clean the Stem
If the stem is in good condition, clean it thoroughly with a damp cloth. Remove any dirt or debris that may have accumulated.
7. Apply Lubricant
To prevent future problems, apply a small amount of lubricant to the stem. This will help the new knob rotate smoothly and prevent it from getting stuck.
| Type of Lubricant | Recommended Use |
|---|---|
| Silicone Spray | All types of stems |
| Plumber’s Grease | Metal stems |
| Teflon Tape | Wrap around metal stems to prevent corrosion |
After lubricating the stem, you can proceed to install the new knob.
Removing the Stem and Washer
To remove the stem, you will need to use an adjustable wrench or pliers to loosen the packing nut. Once the packing nut is loose, you can pull the stem out of the shower body.
The washer is located on the end of the stem. To remove the washer, you will need to use a small screwdriver or a pair of needle-nose pliers. Gently pry the washer off of the stem.
Once the stem and washer have been removed, you can clean and inspect them. If the stem is damaged, it will need to be replaced. If the washer is worn or damaged, it will need to be replaced as well.
Here is a table with more detailed instructions on how to remove the stem and washer:
| Step | Instructions |
|---|---|
| 1 | Turn off the water supply to the shower. |
| 2 | Remove the shower knob by pulling it straight off of the stem. |
| 3 | Loosen the packing nut using an adjustable wrench or pliers. |
| 4 | Pull the stem out of the shower body. |
| 5 | Use a small screwdriver or a pair of needle-nose pliers to pry the washer off of the stem. |
| 6 | Clean and inspect the stem and washer. |
| 7 | Replace the stem and washer if necessary. |
| 8 | Reassemble the shower by reversing the steps above. |
Reattaching the Washer, Stem, and Knob
10. Reattaching the Washer, Stem, and Knob
With the stem protruding from the wall, it’s time to reattach the washer, stem, and knob:
- Slide the washer onto the threaded stem, ensuring it is fully seated against the valve body.
- Next, carefully screw the stem back into the valve body by hand, turning it clockwise.
- Once the stem is fully tightened, gently push the knob onto the stem and secure it by turning it clockwise until it feels firmly attached.
- Verify that the knob can be turned smoothly in both directions without any resistance or leaks.
Additional Tips:
- Avoid overtightening the stem or knob, as this could damage the components.
- If you encounter any leaks after reassembling, tighten the components slightly more until the leak stops.
- For added durability, consider applying a thin layer of plumber’s sealant to the threads before reassembly.
