Kelosauna

This sauna was made from a special type of wood - the so-called polar pines, which have dried out over several centuries due to the cold, dry polar climate. As a result, these pine trunks are not only weatherproof, but also do not warp.
This aromatic wood is sometimes more than 800 years old and is nowadays a very rare and popular material. Due to the spicy, resinous scent of the wood, an infusion with water is actually sufficient.
Because of the relatively high temperature of 90 ° in the sauna and the low humidity of 10-30%, this sauna not only stimulates the circulation, but is also well tolerated.

Hints:
No size and age restrictions
