How can i get privacy for bedroom door?

If you can't add a door that closes, a curtain on a tension rod may help.

Tapestry, beaded curtain, or a folding screen.

Barn door or folding door if a traditional door doesn't work. Curtains won't reduce sound but will obstruct vision. A free standing changing screen would work as well.

You can see how I added a sliding door here: https://www.flippingtheflip.com/2015/05/project-hall-bedroom-sliding-door-done.html

Put a lock on the door.

here is info Joanne and you could also use a blackout curtain and a tension rod it helps cancel noise and light for more privacy

Hello. You might want to go up images of different door locks to see if there’s an available option that you would consider for your door.

You can spay the door if it is glass with etching spray.

Add a door/lock on door, curtain, beaded curtain, etc.

you mean a sign that says privacy, or locks, not sure I understand

Hi! If it's glass that interferes with privacy, a curtain or window film may be the answer. Good luck!

I have used beaded curtains.

Are you asking for ideas on how you can make a bedroom that does not presently have a door that closes more private, other than installing a conventional door?
