True,
we are a little bit nuts about our saunas.
According to
https://saunologia.fi/in-english/ there were around 2,7 million saunas in Finland 2017. That’s about 1 sauna for every 2 Finns.
So I believe that our country probably has the most diverse history of hand made custom saunas to take inspiration from.
As in the old days a new land owners or renters mission was to build a sauna on his new land i the middle of the woods next to a lake.
And then expand from that.
