Replacing Bathtub Knobs

Replacing Bathtub Knobs: A Comprehensive Guide

Replacing bathtub knobs may seem like a daunting task, but with the right tools and instructions, it can be a straightforward and rewarding DIY project. Whether you're renovating an old bathroom or simply want to update the look of your existing tub, following this comprehensive guide will ensure a successful replacement.

Tools and Materials Required:

New bathtub knobs
Adjustable wrench
Allen wrench (if the knobs have set screws)
Teflon tape
Basin wrench (optional but recommended)

Step-by-Step Instructions:

1. Turn Off Water Supply:

Before starting, turn off the water supply to the bathtub. This is usually done by closing the valves behind the tub or under the sink.

2. Remove Old Knobs:

Use an adjustable wrench to loosen the bonnet nut (the large nut directly behind the knob). If the knobs have set screws, remove them with an Allen wrench first before loosening the bonnet nut.

3. Apply Teflon Tape:

Wrap a few turns of Teflon tape around the threads of the replacement knobs. This will create a watertight seal and prevent leaks.

4. Install New Knobs:

Screw the new knobs onto the valve stems by hand as far as possible. Then, use the adjustable wrench to fully tighten the bonnet nuts.

5. Re-connect Water Supply:

Turn on the water supply and check for leaks around the new knobs. Tighten any loose nuts if necessary.

Tips for Success:

Choose durable knobs that are resistant to water and wear.
Use a basin wrench to tighten the bonnet nuts if you have difficulty with the adjustable wrench.
If the bonnet nuts are excessively rusted or damaged, you may need to replace the entire valve assembly.
Test the knobs by turning the water on and off several times to ensure they are functioning correctly.

Conclusion:

Replacing bathtub knobs can be a simple and affordable way to enhance the aesthetics and functionality of your bathroom. By following these instructions and using the recommended tools and materials, you can complete the project with ease and confidence.
