A loose, stripped, or mismatched handle is one of the easiest DIY fixes in a bathroom, and the process works the same for single-handle and two-handle faucets.
What You’ll Need Before You Start
Gather these tools before you touch the faucet; the job goes faster when nothing is missing mid-way.
- Flathead screwdriver (for prying off caps)
- Phillips screwdriver (for handle screws)
- Allen wrench / hex key (for set screws)
- Towel or cloth (to protect the faucet finish)
- Faucet handle puller (only if the handle is stuck)
Turn off the water supply valves under the sink before removing anything. Open the faucet briefly to release pressure and drain remaining water from the lines.
Removing the Old Faucet Handle
Removing the old handle comes down to finding the screw that holds it, which is usually hidden under a decorative cap.
Start by prying off the index button or decorative cap on top of the handle. That red or blue dot (or a plain metal cap) pops off with a flathead screwdriver — wrap the tip in cloth first so you don’t scratch the finish. Beneath it sits the handle screw or a small set screw.
If it’s a Phillips screw, use your screwdriver the same way. If it resists, stop yanking — a faucet handle puller removes stuck handles without damaging the valve underneath.
Installing the New Handle
Installing is the reverse of removal, but you need to verify one thing first: the new handle must match your old stem’s size and configuration.
Place the new handle onto the valve stem, aligning it so it sits correctly.
