Wow this is so interesting! The scenery is totally different from Asia, where saunas are mostly located in spas or gyms in buildings and malls! Japan has a similar "onsen" culture where people soak in hot pools, and it's always a nice experience for me when I visit Japan.
I didn't get to go to an onsen in Japan, but I would love to!
This is like reverse onsen :D
Most of the gyms have saunas here too, so people go after a workout for a few minutes as a relaxation process.
