Building the Sauna

1. Choose a Location:
Select a well-ventilated area with enough space for the sauna. Consider proximity to a bathroom and water source.

2. Build the Walls:
Construct a square or rectangular frame using cedar or aspen lumber. Line the frame with aluminum foil, leaving a 1-2 inch gap at the bottom for ventilation. Install insulation between the studs.

3. Install the Ceiling:
Attach the ceiling lumber to the top of the walls. Add insulation and cover with aluminum foil.

4. Create the Bench:
Build benches using cedar or aspen lumber, securing them to the walls. Make sure the benches are wide enough for comfortable seating.

5. Install the Door:
Hang the door on the exterior frame. Seal the threshold and weatherstrip around the door to prevent heat loss.

6. Setup the Heater:
Place the heater on a cement board and follow the manufacturer’s instructions for installation. Surround the heater with rocks or lava stones.

7. Finish the Floor:
Install cement board on the floor and cover it with a waterproof membrane.

8. Add Lighting:
Install low-voltage sauna lights around the perimeter of the sauna.

9. Install Thermometer and Hygrometer:
Hang a thermometer and hygrometer on the inside of the sauna to monitor temperature and humidity.

Using the Sauna

1. Prepare the Sauna:
Heat the sauna to the desired temperature (typically between 150-185 degrees Fahrenheit). Add water to the rocks and allow the steam to circulate.

2. Enter the Sauna:
Wear loose-fitting clothing made from natural fibers. Take a shower or rinse before entering the sauna.

3. Stay Hydrated:
Drink plenty of water before, during, and after using the sauna.

4. Relax and Enjoy:
Sit or recline on the benches and breathe deeply. Stay in the sauna for 10-15 minutes at first and gradually increase the time as you become accustomed to the heat.

After finishing your sauna session, exit and cool down gradually. Take a cold shower or jump into a pool.
