Ask any international traveler what surprises them most about South Korea, and “the toilets” often comes up in the first five minutes. Heated seats, bidets, motion-sensor flushing, and spotless subway restrooms feel almost futuristic compared to public facilities in many other countries. But this wasn’t always the case. Korea’s toilet culture has a fascinating — and surprisingly emotional — history, shaped by centuries of tradition and one man’s unlikely obsession.
Ancient Beginnings: Toilets from the Baekje Kingdom
Korea’s relationship with sanitation stretches back roughly 2,000 years, to the Baekje Kingdom (18 BC–660 AD). Archaeological finds from this era reveal some of the earliest toilet structures on the peninsula, suggesting that even ancient Korean society placed real value on hygiene and waste management.
Traditional Korean toilets weren’t just holes in the ground, either — designs like the duikkan used two boards placed over a pit to make waste collection more practical for farming communities, since human waste was later composted and used as fertilizer for crops.
The “Night Soil” Era and a Changing Society
For centuries, Korean sanitation revolved around agriculture. Waste collectors known as ddong-jae gathered and sold night soil to farmers, who used it to fertilize their fields.
This practical, almost circular-economy approach worked well in a rural society. But as Korea modernized and opened its ports to the West, imported ideas about hygienic, water-based sanitation systems slowly began replacing these older customs.
A National Embarrassment Before the World Cup
Fast forward to the 1990s: Korea had recovered from war and dictatorship, but public restrooms were still widely seen as dirty, smelly, and something to avoid. When South Korea was chosen to co-host the 2002 FIFA World Cup with Japan, officials realized that millions of international visitors would be judging the country’s hospitality — bathrooms included. This pressure became the spark for one of the most unusual civic movements in modern Korean history.
Meet “Mr. Toilet”: The Man Who Changed Everything
No single person shaped modern Korean toilet culture more than Sim Jae-duck, mayor of Suwon from 1995 to 2002. Sim launched a “Restroom Revolution,” upgrading public toilets across the city and later the entire country — not just for function, but for cleanliness, design, and dignity. In 1999, he founded the Korean Toilet Association, and he later helped establish the World Toilet Association in 2007 to push similar reforms globally.
His dedication went further than policy. In 2007, Sim demolished his own 30-year-old home and rebuilt it in the shape of a giant toilet bowl, naming it Haewoojae — a Buddhist-inspired term meaning “a place to relieve one’s worries.” After his death in 2009, his family donated the house to the city of Suwon, where it now stands as the Mr. Toilet House Museum, surrounded by a quirky Toilet Culture Park filled with sculptures and exhibits on sanitation history from around the world.
The Legacy Today: A Global Model for Public Sanitation
Thanks to Sim’s efforts and the momentum that followed, South Korea passed the Public Toilet Act in 2004, mandating clean, accessible restrooms in parks, transit stations, and tourist areas nationwide. Today, Korean public toilets are famous for their spotless conditions, high-tech bidets, and thoughtful design touches — some restrooms even feature calming music or art installations. For travelers visiting Korea, a clean restroom is rarely more than a few minutes away, a small but telling symbol of the country’s broader commitment to public comfort and civic pride.
Planning a trip to Korea? Visiting Haewoojae in Suwon (just a short trip from Seoul, and free to enter) makes for one of the most surprisingly memorable stops on any Korea itinerary — proof that even the most overlooked parts of daily life can carry an extraordinary story.
