15 saunas in 2 cities
Fifteen addresses, but only two cities: Thirteen of the Korean saunas are located in Seoul, two in Busan. There is no stronger concentration in this overview.
Seoul alone has more houses than the whole of Italy or all of Spain. For travelers, this means that the choice is reduced to a city map — and that nothing is entered outside of these two cities, which does not mean that there is nothing.
This page does not provide a verified classification of the legal situation for South Korea. It is one of the points that should come from an up-to-date, independent source before a trip.
Beyond the saunas, almost nothing is recorded for South Korea: a single cruising address, not a gay hotel. This category is practically the only one in which the country appears on this portal at all.
