Hey man, you Fins think you own the sauna ,?! Well. I grew up in northern Ontario, Canada, and we had TWO, one in the house, the other at the cabin. We used to roll out of it in Jan/Feb, naked, temp. at something stupid below zero, roll in the snow, and get back in. Do it again! And again! Then go drink some good Canadian whiskey. Boys AND girls! Ah, old times, good times!
Anyways, just joking with you. The Finn Sauna really is the best. (but the above is true)
As for your Eagle, lots of work to be done, but it is a great undertaking. If you need any help or parts, please ask, we will try to help. BTW, I live in the USA, but I am from CZ.
good luck, gz
