I will do my best to be helpful without too much promotion for our product. We do enjoy the sauna loving community. We focus on a steamy wet sauna. Heat is needed of course, but putting that heat right to work making steam is our goal for our saunas. I see waisted heat in many other saunas. I know I get little pleasure from a super hot dry feeling sauna. We have found the key to this in a well insulated building that can drain thru as much water as you want. The other component is the stove. It must be super strong and not firebrick lined. You want the heat to go into your rocks not out the chimney. To best do this a 1/4” round steel firebox is great. Not only will a round firebox expand and contract with no damage, it allows rocks to saddle over the heat, on the sides as well as the top. As quite an added benefit, the escaping heat to the sides is reduced, and thus less heat to close wall surfaces.
Again I understand that most people here want to build their own sauna and I understand that and am willing to share.
