A post going around Reddit this week features a photo of a bathroom in Korea that has a display installed. This monitor provides a bunch of information, but most prominently, it tells people which stalls are occupied and whether the stalls have a regular or squatting toilet. (Squatting toilets are popular in Asia; feel free to go down an internet rabbit hole about them.)

This is all obviously useful information to have, and infinitely preferable to having to look at the occupied knob on a door, or, in a worst-case scenario, whether you see someone’s feet. It also beats these bathroom lights that seemed like a brilliant idea in 2014.

I’m not sure how this display is being updated, like is it relying on the door locks to communicate back? Is someone manually updating it? I realize there likely isn’t a bathroom attendant running back and forth between stalls to keep the display current, but I’m going to dream.

The display also shows the temperature and humidity outside, as well as how stocks are doing that day. It’s always nice to be reminded of the outside world while dealing with the horror that is a public bathroom. Good job, Korea, you’ve figured out the ideal way to let people know whether a stall is taken.
