Doors – Install a single handle with latch on closet door

You can replace the doorknob hardware with a ball latch/strike plate. These can be easily pushed open and are often used for places like pantries where you don't need privacy and may have your hands full when trying to open/close the door. You'll also want to replace the doorknobs with dummy versions that don't swivel.

If you just want the bathroom door held closed, remove the latch mechanism totally, install a dummy knob and use a magnetic closure to hold the door in place.

You do not even need the magnet to touch the matched plate on the stronger ones. If you are using a bit of foam or a vinyl bumper on the door itself, adjust the magnet back from the plate until it is about 1/16 inch away. It will hold without a click.

If you need a lock for other times, use a surface mounted privacy bolt.
