Select the Right Location
Choosing the right spot for your sauna is key. Look for a level area with good drainage. You’ll want it conveniently located near your home, but not too close to bother neighbors. Consider sunlight exposure as well – a shady area will stay cooler. Make sure you check local regulations for any restrictions on outdoor structures.
Consider Dimension and Layout
Standard sauna dimensions are typically around 5 x 7 feet, but you can adjust this to fit your space and needs. Decide on the desired layout – will it be square, rectangular, L-shaped? Allow space for benches, the sauna stove, and room to move around easily. A basic layout has benches along two walls and the stove on a third wall with the door on the remaining one.
Use Affordable and Efficient Materials
For budget DIY construction, utilize inexpensive wood options like spruce or cedar which withstand weather and heat. Use standard lumber for the framing along with plywood for the walls and ceiling. Make sure exterior materials are protected from moisture. Install fiberglass insulation to retain heat. Use a sealant made for saunas on the wood benches. Source rocks or used bricks cheaply for the sauna stove foundation.
Ventilation is Key
Proper ventilation keeps the air fresh and prevents overheating. Install adjustable intake and exhaust vents on opposite sides of the room. Place the intake vent low on a wall and the exhaust up high. Use moisture resistant vent covers. Provide sufficient airflow – around 5 cubic feet per minute of fresh air per person.
Select an Efficient Sauna Stove
This is a significant investment, so look for an affordable but high quality sauna stove optimized for efficiency and safety. Seek ones made from long-lasting materials like stainless steel with enclosed, insulated fireboxes. Look for adjustable temperature controls and rocks included. Consider a used stove to save. Properly install the stove by following manufacturer guidelines.
Use Electric Heaters Wisely
Efficient electric heaters can be a budget option, but higher wattage is needed for a sauna. Look for waterproof designs made for sauna use. Install according to electrical load limits, and place safely away from flammable surfaces. Using an electric heater will eliminate the need for a stove and venting. But electric options often don’t produce an authentic sauna experience.
Add Touches Like Wood Benches
You can save money by making your own simple wood benches. Use heat-treated lumber and leave spacing between boards for airflow. Fasten the benches securely to the walls, keeping them low for safety. Or look for affordable used benches. Also consider adding wood paneling or other decorative yet budget friendly touches for an inviting feel.
Use Sauna Accessories Sparingly
While not essential, small accessories can enhance the experience. Use budget finds like a water bucket, ladle, thermometer, and sand timer. Look for inexpensive options: a plastic bucket, basic timer, and simple wall thermometer work fine. Lighting like wire caged sauna lights also adds ambiance without breaking the bank.
Consider DIY Building and kits
If you have carpentry skills, building the entire sauna yourself following a good set of plans can optimize cost savings. There are also a variety of budget friendly sauna kits available that include pre-cut lumber and instructions. Just prepare the foundation, assemble using basic tools, add insulation, and install the stove and vents.
Add Finishing Touches
Once constructed, caulk all seams and gaps. Paint or stain the exterior as desired. Install benches, accessories and safety railings. Lay down a towel or floor mats. Give the sauna a test run to work out any kinks before finishing the interior. Then relax and enjoy your new budget-friendly outdoor sauna oasis!
Frequently Asked Questions
Here are some common questions about building an affordable outdoor sauna:
How much does it cost to build a basic DIY sauna?
A simple 5×7 foot sauna can be built for $1000-$2000 in materials if you have the lumber and do the work yourself. The biggest costs are the stove ($500-$1000) and wood for quality benches.
What is the best wood to use?
Western red cedar and spruce are great wood choices as they can handle the heat. Use kiln-dried lumber to limit warping. Avoid pressure-treated wood inside.
Do I need a permit to build an outdoor sauna?
It’s wise to check with your local building department first. Often, permits are required for structures over 100-200 square feet. There may be restrictions on placement as well.
What temperature should I keep the sauna at?
A typical sauna temperature is 160-190°F. The ideal range depends on personal preference. Install thermometers at various heights to monitor the temperature.
How long does an outdoor sauna normally last?
A well-built outdoor sauna can last for 15-20 years or more with proper maintenance. Protecting the wood from moisture and weather is key for longevity.
What’s the best way to heat my outdoor sauna?
A wood burning stove offers an authentic sauna experience, but requires venting. Electric heaters are convenient and easier to install but need high wattage to heat properly.
How much airflow is needed in the sauna?
Aim for around 5 cubic feet per minute (cfm) of fresh air flow per person in the sauna, via adjustable intake and exhaust vents.
Conclusion
Building a cost-effective outdoor sauna is an achievable project that can provide years of relaxation and enjoyment. With smart planning, affordable materials, and efficient construction, you can create a peaceful backyard sauna retreat without breaking the budget. Just focus on the essentials like proper layout, ventilation and a safe heating system. By doing the work yourself and using budget finds, your dream sauna can become a reality.
