A planning guide for builders and designers: sizing, power, ventilation and the choice between traditional, infrared and outdoor barrel saunas.
A sauna for a private residence is planned differently from one for a hotel spa or a club locker room. Decide how many people will use it at once, how often, and whether it is a feature room or a quiet amenity. That one answer drives size, heater type and finish level.
Traditional saunas use a heater and stones and typically need a dedicated electrical circuit and ventilation. Infrared cabins heat the body directly, are usually plug-in or hard-wired at a lower load, and suit smaller rooms. Outdoor barrel and cabin saunas need a level base and clearances but add a destination feel to a property. Each type has different power, floor and moisture needs, so choose before framing and finishes are locked.
Ask for the electrical requirements from the specific model you are considering and have your electrician confirm them. Plan supply and exhaust ventilation, a floor drain or water-tolerant flooring where steam is involved, and a door and glass specification suited to heat. Confirm local code and any health-department rules for commercial installations.
Wood species, bench layout, lighting and glass change how the room feels. For hospitality, plan for cleaning and wear. For residences, plan for the view and the way people will move through the space.
