How to Fix a Loose Single Handle Bathroom Faucet

A loose single handle bathroom faucet can be a frustrating problem, but it's one that can be easily fixed with a few simple tools and a little bit of time. Here's a step-by-step guide on how to do it:

Turn off the water supply to the faucet. There should be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise until they are fully closed.
Open the faucet to release any remaining water in the lines. This will help prevent water from leaking out when you remove the faucet.
Remove the aerator. The aerator is the small screen at the end of the faucet spout. It can be unscrewed by hand or with a wrench.
Locate the packing nut. The packing nut is a large nut that is located just below the aerator. It is used to tighten the faucet handle.
Tighten the packing nut. Using a wrench, tighten the packing nut clockwise until it is snug. Do not overtighten, as this can damage the faucet.
Reinstall the aerator. Screw the aerator back onto the faucet spout by hand.
Turn on the water supply to the faucet. Check for leaks around the faucet handle. If there are any leaks, tighten the packing nut further.

If you have followed these steps and the faucet is still loose, there may be a more serious problem with the faucet. In this case, it is best to call a plumber for assistance.
