Place the newly tightened handle back over the valve stem. Make sure to align the splines so the handle is in the correct 'off' position. Once aligned, screw the entire handle assembly clockwise back onto its base on the tub deck. Hand-tighten until it is snug and secure.

Goal: Reattach the handle to the faucet

  • Ensure the splines are properly engaged before tightening to prevent misalignment or damage.

FAQs

Why is it so important to turn off the water supply before starting, and what if I can't find the shut-off valve?

Turning off the water supply is crucial to prevent flooding and serious water damage during the repair. If you can't find local shut-off valves near your shower, you'll need to turn off the main water supply to your entire home, usually found near your water meter or hot water heater.

What should I do if the screws on my old shower knob are stripped or stuck, making them difficult to remove?

If screws are stripped, try placing a wide rubber band flat over the screw head to provide extra grip for your screwdriver. For stuck screws, a little penetrating oil applied and left to sit for a few minutes can help loosen them. In more stubborn cases, a screw extractor kit may be necessary.

How long does this shower knob repair project typically take for a beginner, and what's the average cost?

For a beginner, this project usually takes about 30-60 minutes, assuming you have all the necessary tools and the new knob on hand. The cost largely depends on the new shower knob, which can range from $15 for a basic model to $50+ for more decorative or brand-specific replacements.

Do I need the exact 'Milwaukee 8 in. x 3/8 in. Slotted Flat Head Screwdriver' mentioned, or will any flathead work?

You do not need that exact brand or model of screwdriver. Any standard flathead screwdriver with a tip width of approximately 3/8 inch and a Phillips head screwdriver of appropriate size for your knob's screws will work. The Milwaukee tool is simply an example of a suitable option.
