This German article by Kira Hanser describes the current sauna scene trends in Germany, FInland and in Estonia:
The craziest saunas in Europe
Naked in the gondola (nacelle). On city tour in a sauna bus. Sweating and baking rolls. In Germany, Finland and Estonia sauna-goers are increasingly entertained. An odd choice.
The Germans are almost as crazy as the Finnish sauna lovers. 30 million people sweat together regularly – that at least the German Sauna Association says. And they are increasingly demanding.
Therefore, according to the “Guinness Book of World Records,” the world’s largest sauna is consequently not somewhere in Scandinavia, but in Baden-Württemberg’s Sinsheim in Germany.
166,10 square meters – up to 150 people can fit inside. At the same time they can watch Japanese Koi Carps in an aquarium. …
The desire of the Germans for sauna sessions did certainly not remain unnoticed by the Federal Ministry of Finance. Taxes will rise soon. Through higher costs therefore the sauna entry prices could increase by twelve percent.
For this reason people come up with new sauna ideas, so guests may not stay away. …
For example, in Tallinn, the Estonian capital, guests covered in just their bathrobes climb from the hotel directly into a sauna bus for the nudist city tour. However, the windows are mirrored. …
Gondola with Sauna
And the craziest sauna in the world? This seems to be in Finland. At the Arctic Circle people can sweat at 100 degrees -naked in a gondola.
About 20 minutes the hot ride takes you up the mountain Yllas and back again, just upto four people. For all cases during a power failure, warm clothes and a fire extinguisher are on board.
It is probably the world’s most expensive sauna: 1500 € is the gondola rent for two hours.
