"I just wanted to flush. Why are sirens ringing?!"

Don't Press the Red Button: The Korean Bathroom Guide

Using a bathroom in Korea sounds simple, until you're staring at a wall of buttons, a control panel full of Hangul and one very suspicious red switch. From subway stations to your Airbnb, here's how to avoid setting off an alarm, getting a surprise water show or shocking your host.

1. 1The red button is NOT the flush

   

   In public restrooms across Korea, from subway stations and Han River parks to shopping malls, you'll often find an emergency call button inside the stall, labeled "비상벨" (emergency bell). It's there for safety. Press it, and an alarm goes off. In many places it connects straight to the police. In others, it calls the building's security or management office. The flush, on the other hand, is usually a small lever, a button marked "물 내림," or a sensor that works on its own.

   Pro tip: Don't be the tourist who presses it, then has to explain through the door that everything is fine. If you press it by accident, don't panic: tell the staff "괜찮아요" (gwaenchanayo, I'm okay).

2. 2The bidet looks like a spaceship. It's fine.

   

   Many Korean toilets come with a bidet panel. Don't panic when you see Hangul. Here are the four buttons you need:

   • 세정sejeong · rear wash
   • 비데bide · front wash
   • 건조geonjo · warm air dryer
   • 정지jeongji · stop

   Pro tip: Rookie mistake: pressing the dryer first and getting a surprise warm breeze. When in doubt, hit 정지 (stop) and start again.

3. 3Meet the bathroom slippers

   

   Staying in a Korean home, guesthouse or Airbnb? Most Korean bathrooms are "wet rooms." There's often no shower curtain or separate shower booth, so the whole floor gets wet every time someone showers. That's why Korean homes keep a separate pair of plastic slippers just for the bathroom. Slip them on when you go in, and take them off when you come out.

   Good to know: Some newer places, especially hotels, have dry bathrooms with a separate glass shower booth. But in most Korean homes, the bathroom is still a wet room.

   Pro tip: Never wear the bathroom slippers into the rest of the house. That's the fastest way to make your Korean host gasp.
