Borda,
My father-in-law has built a bonya, now I want to give it a try. The wooden structure doesn’t seem to hard but the oven is the key.
Any diagrams or spec’s you could send me to help. Russian/English doesn’t matter I can read both.
I know my in-laws use a wood fired stove with a large "tube" of water over it, with a small vent pipe into the room, is this for radiant heat?
