A Global Ranking of Public Toilets: What Does it Mean for Travelers and Cities Alike?
The study by QS Supplies analyzed public toilet access across global cities and tourist hotspots, paying special attention to availability within the United States and the United Kingdom. The team used OpenStreetMap data to calculate the number of public toilets per 100,000 people across major cities worldwide, including in the US and UK. By combining these city metrics, they determined the overall national average for each country. Locations lacking defined borders on OpenStreetMap were removed from the dataset. Additionally, the team made manual corrections for cities with inflated figures caused by university campus restrooms, which are typically off limits to the general public.
Among the main findings, Chiang Mai, Thailand, ranks first globally for large cities with 92.7 public toilets per 100,000 people. Zurich, Switzerland, offers the best access among global tourist hotspots at 76.5 restrooms per 100,000 residents. Meanwhile, Exeter tops the UK with 38.7 per 100,000, and Salt Lake City claims the highest density in the U.S. (and fifth highest worldwide) at 66.6 restrooms per 100,000 people.
