Quick take: Choose indoor for convenience and controlled conditions; choose outdoor when space, privacy, and backyard experience matter more.
Indoor sauna kit advantages
Indoor kits can be easier to access daily and may avoid weather exposure, but they still need space, ventilation, and electrical planning.
Outdoor sauna kit advantages
Outdoor kits preserve interior square footage and create a backyard wellness destination, but may need more site prep.
