This is how I fixed my bathroom door.
One day, Monkey Boy decided to swing with his full weight, hanging from the door handle of the bathroom door. Not surprisingly, the screws holding the hinge to the 30-year old bathroom door decided that they'd had enough, and gave up. The screws pulled out of the door and the holes were permanently stripped.
Like most ordinary folks, we enjoy privacy during bathroom time, so I needed to fix it.
I had tried the toothpick and glue method shown here in the past on another door in the house when something similar happened involving a gaggle of giggling teenagers. It did not work well for me, so I decided to try a more robust method.
I'll be drilling out the stripped holes and gluing in dowels to fill the holes.
Step 1: What you'll need:
A wooden dowel (I used a 4ft long 3/8" poplar dowel - $0.84 at a local store)
A saw of some kind if you need to cut your dowel
A 3/8" drill bit (I used a Forstner bit)
A smaller drill bit (to drill new pilot holes after you've patched the old holes)
The dowel I bought was 48" long, so I cut off three pieces that were around 1.5" long. I didn't measure, and used a little hand coping saw to cut them to size. I had some 80 grit sandpaper nearby so I used that to smooth and square off the rough looking cuts I made.
