Let’s see if anybody is smart or creative enough to figure this out. Or maybe it’s been solved and I don’t know.

Bathroom is shared with room 1 and room 2.

Currently, inside the bathroom there’s a door knob that can lock. The push button type. Privacy lock. On the room side, there’s a deadbolt to lock it, and you can “unlock” the bathroom door using a screwdriver or a coin.

Problem:
1. person from bathroom 1 uses bathroom. Forgets to unlock door 2.

2. With a screwdriver or coin, can easily unlock the door when someone is showering inside.

Is there a better simple solution? Without fancy electronic locks.

Ideally, when person from room 1 enters to use bathroom, he locks door from room 2 which at the same time locks door 1. When he exits bathroom, he unlocks door 1 which also unlocks door 2.

I think from a practical standpoint, you win for the given diagram. thank you. if the distance between the 2 doors is long then that's a long bar.

now for those who have the doors to room 1 and room 2 on the opposing side facing each other, that's not solved lol.

itu kepala otak never read the question properly.
