I am lead to believe this motel was not built or run by Finns.
An air conditioned sauna really defeats the purpose of sauna, no?
Nor Scots, since why waste all that money to cool something that was meant to be steamy hot.
Perhaps it was a gimmick to draw in the curious.
I suspect "air conditioned sauna" was a euphemism to describe Selkirk in summer.
The place is still there in Selkirk but looks like the air conditioned sauna was ditched for a hot tub.
