Ice Cave
According to the traditions of some Northern people, they usually spend some time in the fresh air after a searing hot sauna. Today we have the technological means to create a similar experience, no matter what the current season is.

The temperature in the ice cave is zero to minus 3°C. This sub-zero temperature ensures that the cave is constantly covered in ice. It is not common to use traditional building materials in the case of ice caves, so the cabin is built from panels designed for this exact purpose, since the cave has to be thermally insulated.
