Home Sauna Installation Guide: What to Expect

Electrical Requirements

120V / 15–20A: Most 1–2 person infrared saunas. Standard household outlet. No electrician needed.

240V / 30–60A: Traditional saunas and larger infrared units. Requires a dedicated circuit installed by a licensed electrician. Budget $200–$600 for electrical work.

Space Planning

• Allow 6 inches of clearance on all non-wall-adjacent sides for air circulation
• Ensure the floor can support the sauna weight (300–1,200 lbs depending on model)
• Concrete, tile, and hardwood floors all work well; carpet is not recommended
• Door must swing outward (fire safety requirement)

Ventilation

Indoor saunas need air intake near the floor and exhaust near the ceiling. Most pre-built saunas include ventilation panels. Ensure the room has adequate airflow to prevent moisture buildup in the surrounding space.

Flooring Inside the Sauna

Cedar or teak flooring grates are standard and ideal. Avoid unfinished wood that will absorb sweat. Non-slip surfaces are important for safety.

Outdoor Sauna Installation

For barrel and cabin saunas, you'll need:

• Level, stable foundation (gravel pad, concrete pad, or treated lumber cradles)
• Weatherproofing oil or treatment applied annually
• Outdoor-rated electrical run to the location
• Local building permit in many jurisdictions (check before ordering)
