Meet Kaj
“Kaj is the one who welcomes you to the sauna. Wood-fired warmth, fresh lake air and a slightly different sauna experience await. Just bathe in the sauna!”
A little piece of Swedish lake life
The sauna sits on Borsöknasjön, near Eskilstuna in Södermanland, Sweden. It's where wood-fired warmth, lake water and nature come together – along with time spent with the people you care about. The lake has its own mood in every season. When the ice lies on the lake, we saw an ice hole for a swim.
