Choosing the Perfect Site

Choosing the ideal site for your portable Outdoor infrared sauna is vital for a safe and enjoyable experience. Accessibility is key. Opt for a spot that’s easy to access from your camping area, avoiding tricky terrain or dense underbrush.
Proximity to a water source is also important. A cool dip in a nearby lake or stream after a sauna session can be refreshing. Additionally, having drinking water nearby helps you maintain hydration. Ensure the ground is level and stable to support the sauna structure. Uneven or unstable ground can make your sauna shaky and unsafe. Use UV-resistant materials to help your sauna endure prolonged sunlight and other elements.
Gathering Materials and Tools
Gathering all the necessary materials and tools beforehand is crucial for a smooth start to your summer camp. Most of these items are readily available and budget-friendly. Assembling the sauna in a garage can be convenient, providing a sheltered workspace before transporting it to the campsite. Essential materials include:
· A waterproof tarp (10’x12’) for constructing the shelter
· 30 feet of 1-inch diameter PVC pipe for the frame
· 10 feet of 1/2-inch diameter pipe for the frame
· Panels (such as wall panels or ceiling panels) for improved insulation and structure
· A heater (electric or wood-fired)
The materials and tools needed to assemble the frame securely are:
· Six three-way Tee fittings for the 1-inch PVC pipe
· A PVC cutter or saw to cut the pipes to the correct lengths
· Rope to assist in assembling the structure and securing the tarp
Gather sand, stones, and durable, non-weathered igneous rock for the heating element, as well as a plastic sheet for the floor to keep it dry. Also, collect all necessary fittings, nails, and tape for securing the material structure.
With all materials ready beforehand, the process becomes smoother and more enjoyable, providing added convenience. This allows you to focus on the fun of building and assembling your portable sauna without interruptions.
Building the Frame
The frame serves as the foundation of your portable sauna, providing essential structure and stability. To build it, follow these steps:
· Gather the necessary materials: poles, duct tape or heavy-duty tape, polyethylene film, rope for tying, and stones
· Measure and cut all frame components accurately for a perfect fit
· Ensure the overall dimensions are approximately 95 inches high, 6 inches wide, and 48 inches deep
· When constructing the frame or bending the arch, use a rope to tie together parts of the frame. This helps secure and shape the structure during assembly, ensuring stability
To work with the PVC pipes:
· Connect the PVC pipes using the three-way Tee fittings
· Cement the fittings to the horizontal pieces to keep the structure portable, allowing for easy disassembly and reassembly during trips
· To bend the PVC pipes, hold them in boiling water for about five minutes to make them flexible. You can also tie the pipes in place with rope while they cool to maintain the desired arch
After assembling the frame, wrap the center tarp section around it to test the fit. Make sure you attach the tarp securely to the frame to ensure stability and weather resistance. Ensure the frame is sturdy and capable of withstanding outdoor elements, providing a safe and durable sauna structure.
Adding the Shelter
With the frame in place, add the shelter to transform it into a cozy sauna house. Cut the tarp into a long, mostly rectangular strip with two quarter-circle edge pieces. Measure and cut, allowing at least 6 inches for overhang to ensure a snug fit over the frame.
Fold and sew the corners to help it fit tightly over the frame, offering better protection against the harsh elements attached to the tent. You can also throw the tarp over the frame for quick coverage.
Use adhesive velcro strips for closures to make it easy to enter and exit the unit and still maintain a good seal at the door. This shelter will protect you from wind and rain and retain heat inside for a perfect steam room atmosphere.
Insulation and Vapor Barrier
Proper insulation and a reliable vapor barrier are essential for any DIY sauna for home, especially when you want your portable unit to operate as a true steam room. Foam insulation is a great choice for lining the walls and ceiling, as it helps trap the heat generated by your sauna stove, keeping the temperature steady and comfortable inside. This not only makes your sauna more energy-efficient but also ensures you get the most out of every sauna session, even on cooler camping nights.
To protect your sauna from moisture and steam, install a vapor barrier on the outer part of the insulation. This barrier prevents steam and moisture from escaping, which is crucial for maintaining the integrity of your materials and keeping the floor and walls dry. In a portable sauna, where the structure is exposed to the outdoors, a well-sealed vapor barrier is your best defense against water damage and heat loss.
Finishing the Back Walls
The back walls of your DIY sauna play a vital role in both structural support and heat retention. For a truly relaxing sauna session, consider finishing the back walls with cedar shiplap or another durable, moisture-resistant material. Cedar is a classic choice for saunas because it naturally resists moisture and adds a pleasant aroma to your steam room.
When designing the back walls, leave space for the sauna stove and any necessary vents or fittings. This will help with proper airflow and ensure your sauna heats evenly. If you’re looking to save money, reclaimed or recycled materials can be a smart option.
A well-built back wall helps retain the heat and also creates a cozy, inviting atmosphere inside your sauna. With the right materials and a little attention to detail, you’ll have a sturdy wall that supports your stove, protects your sauna from the elements, and makes every sauna session more enjoyable.
Installing the Sauna Stove
The heart of any sauna is its stove. For a portable sauna, you can choose between electric or wood-fired options. Electric stoves are convenient and easy to use, with a power rating of about 7 kW, suitable for small to medium saunas, and take about 30-45 minutes to reach optimal temperatures.
Wood-fired stoves offer a more authentic sauna experience but require proper ventilation and regular fire maintenance. Recommended wood species include:
· Oak
· Linden
· Alder
· Birch
· Ash for efficient burn and consistent heat.
Regardless of the stove you choose, install it safely and securely inside your portable sauna. Ensure proper ventilation and adhere to safety guidelines to prevent accidents or injuries. Once installed, your sauna stove will create the perfect steam room environment.
Heating the Sauna

With your sauna stove installed, it’s time to heat things up. A traditional method involves:
· Making a fire and placing stones in it
· Using dense igneous stones that absorb and radiate heat into the sauna
· Arranging the hot rocks loosely to allow airflow, enhancing heating efficiency and safety
For a more modern approach, consider commercial infrared heaters, which provide consistent and controlled heat. These heaters are popular among DIY sauna enthusiasts. Regardless of the method, it usually takes about an hour for the stones to heat up.
Safety is paramount when heating the sauna. Follow these guidelines:
· Regularly inspect sauna rocks for cracks or wear
· When using water to create steam, pour it gradually onto the rocks to avoid thermal shock and excessive steam bursts
· Maintain the sauna temperature between 150°F and 195°F
Stay hydrated before, during, and after your sauna session, as the heat can cause significant fluid loss. Following these steps ensures a perfectly heated sauna, ready for a relaxing and rejuvenating experience.
Setting Up Benches and Flooring
Comfortable seating and proper flooring are crucial for a relaxing sauna experience. Set up the benches inside your portable sauna. The lower bench should be 3-1/2 inches high, 56 inches wide, and 26 inches deep, while the upper bench should be 3-1/2 inches high, 56 inches wide, and 15 inches deep.
These benches provide ample seating space for you and your fellow campers. Ensure the benches are sturdy and securely fitted to prevent accidents. Comfortable seating enhances relaxation and makes sauna sessions more enjoyable.
Use a plastic sheet for the flooring to keep the ground dry and clean, protecting the ground beneath and easing cleanup. With benches and flooring in place, your portable sauna is ready for use.
Interior Design and Comfort
Creating a comfortable and inviting interior is key to making your DIY sauna a favorite spot for relaxation. Start by building benches from moisture-resistant materials like cedar or hemlock. These woods are durable and remain cool to the touch, even when the sauna gets hot. Arrange the benches to provide plenty of seating space, so everyone can stretch out and enjoy the heat.
For the floor, choose a material that can handle both high temperatures and moisture, such as tile, stone, or a well-sealed wooden platform. This will help keep the space clean and safe, even after multiple sauna sessions. If you want to add a touch of luxury, consider installing a tempered glass window or a door with a tight seal to keep the heat in and let in natural light.
Don’t forget to include a spot to pour water over the hot rocks, a classic sauna ritual that creates soothing steam and enhances the overall experience.
Enjoying Your Sauna Session

After all the hard work, it’s time to enjoy the fruits of your labor. Find a scenic location for your portable sauna to enhance relaxation and rest during winter. Stepping into the warm, steamy environment will help melt away stress and tension.
Adding essential oils to the water can elevate your sauna experience, offering therapeutic benefits and aromatic enjoyment. Add oils to the water, not directly to the rocks, to avoid fire hazards. Adopting breathing techniques can enhance relaxation and help you acclimatize to the heat.
After your sauna session, cool down properly. Gradually lower your body temperature with a cold shower in a nearby stream. Listen to your body. If you feel dizzy or lightheaded, step out of the sauna and cool down immediately.
