Learn the essential steps for setting up and using an indoor far infrared sauna, including placement, assembly, first use, and maintenance tips.

Quick Answer

Set up your indoor far infrared sauna on a level, heat-safe floor near a grounded outlet, assemble it according to the manual, then start with a 20–30 minute session at a comfortable temperature to let your body acclimate.

Why Placement Matters More Than You Think

Where you put your sauna affects both safety and comfort. A level, sturdy surface prevents wobbling, while keeping it away from moisture sources like showers or pools protects the wood and electrical components. Also, ensure at least a few inches of clearance around the unit for airflow, especially around the heater.

First Session: What to Expect

Your first infrared sauna session is about acclimating, not pushing limits. The heat feels different from a traditional steam sauna—it's gentle and penetrating. Start at a lower temperature and stay hydrated. Expect to sweat within 10–15 minutes. If you feel dizzy or uncomfortable, step out and cool down.

Step-by-Step Setup and Use

Choose the Right Location: Place the sauna on a level, heat-resistant floor such as tile, concrete, or a hardwood floor with a mat. Avoid damp areas and ensure the room has adequate ventilation. Keep at least 6 inches of clearance on all sides for airflow and heater ventilation. Check that the floor is level with a spirit level before assembly.
Assemble the Sauna: Follow the manufacturer's manual carefully. Typically, you'll need a second person for lifting panels. Use the provided hardware and avoid over-tightening screws to prevent wood splitting. Ensure all electrical connections are secure and the unit is grounded. Do a final check of all screws and connections before first use.
Preheat and Test: Turn on the sauna and set the temperature to a low setting (around 100°F) for 15–20 minutes. This burns off any manufacturing residues and confirms the heater works. Then, turn it off and let it cool. Expect a slight 'new wood' smell during the first few sessions; it should fade.
Prepare for Your First Session: Shower before entering to remove oils and lotions. Bring a towel to sit on and a bottle of water. Set the temperature to a comfortable level (start around 110–120°F) and plan for a 20–30 minute session. Never exceed 30 minutes on your first visit; your body needs time to adapt.
During the Session: Sit or lie down, relax, and breathe deeply. You should start sweating within 10–15 minutes. If you feel lightheaded, exit and cool down. Keep a towel under you to absorb sweat and protect the wood. Listen to your body—it's okay to step out earlier than planned.
After the Session: Turn off the sauna, open the door, and let it cool. Wipe down the interior with a dry cloth to remove moisture. Shower to rinse off sweat. Drink water to rehydrate. Clean the sauna after each use to prevent mold and keep the wood in good condition.
Maintain Your Sauna: Regularly inspect the wood for cracks or warping. Clean the interior with a mild wood cleaner as needed. Check the heater and electrical cords for wear. Follow the manufacturer's maintenance schedule. Address any issues promptly to extend the life of your sauna.
