A backyard sauna turns a corner of the yard into a year-round retreat, and building your own runs a fraction of the cost of a prefab kit. The plans below range from a compact 6×6 that seats two up to a 12×22 with its own covered cooling porch, so you can match the footprint to your space and how many people you want on the benches at once. Each design downloads as a free printable PDF covering framing dimensions, a cut list, and the bench layout that puts you up in the heater’s hot zone where a sauna actually does its work.
