It has been dream of mine to build a sauna. I'm thinking of using a stone shed in the garden. Has anyone tried this? Most of the plans I have found are for dry heat saunas as opposed to wet steam room types so maybe they are easier to build/maintain. I was going to use an old cuisiniere from the original house as a heat source and insulate with Celutex plus Superquilt and then line with planks. Does it have to be cedar or would another wood work? Any words of wisdom for a basic DIYer? Am I destined for failure or is there a sweaty future in sight?
