Outdoor Sauna Buying Guide: How to Choose the Best Outdoor Sauna for Your Backyard

In this comprehensive buying guide, Aurum Apex walks you through what you need to know to choose the best outdoor sauna for your backyard space, climate, lifestyle, and personal wellness preferences.

1. Understanding Sauna Types: Traditional vs. Infrared vs. Barrel Saunas

The first major decision when shopping for outdoor saunas is determining which heating technology and enclosure style best suit your space, preferences, and lifestyle.

A. Traditional Cabin Outdoor Saunas

Traditional outdoor saunas use electric or wood-burning heaters to heat the air inside the sauna room. Depending on the sauna and heater, traditional saunas commonly operate at temperatures between approximately 150°F and 195°F (65°C to 90°C).

• Best for: Homeowners who prefer a traditional high-heat sauna experience, the option to create steam by adding water to appropriate sauna stones, and classic multi-tiered seating.
  

B. Outdoor Barrel Sauna

The barrel sauna has become a distinctive feature in many American backyards because of its cylindrical architecture and efficient use of interior space. Its curved design helps promote natural heat circulation while creating the rustic appearance associated with traditional outdoor sauna experiences.

• Efficient Design: The curved shape can reduce unused interior air space compared with some rectangular sauna designs and helps promote efficient heat circulation.
• Weather-Shedding Design: The curved roof helps shed rain and debris. Snow-load capabilities vary by model and should always be confirmed with the manufacturer.
• Best for: Homeowners seeking an efficient outdoor sauna design with a distinctive, rustic aesthetic.

C. Outdoor Infrared Sauna

An outdoor infrared sauna uses infrared heating elements, commonly including carbon or ceramic technologies, to provide radiant heat. Unlike traditional saunas, which primarily heat the surrounding air, infrared saunas use radiant energy to warm the body more directly and generally operate at lower ambient temperatures, commonly around 120°F to 150°F (49°C to 65°C) depending on the model.

• Energy-Efficient Operation: Infrared saunas generally operate at lower temperatures and may require less warm-up time than traditional high-temperature saunas
• Lower-Temperature Experience: The lower ambient operating temperature may appeal to users who prefer a gentler heat experience

2. Choosing the Right Sauna Heater: Electric vs. Wood-Burning

The sauna heater plays a central role in determining operating temperature, warm-up time, and the overall sauna experience. Selecting the appropriate heater type and kilowatt (kW) capacity is important for consistent performance, particularly in colder outdoor climates.

Electric Sauna Heaters

Electric heaters are a popular choice for residential outdoor saunas, particularly in urban and suburban settings.

• Convenience: Depending on the heater model, controls may include digital touchpads, programmable settings, or compatible mobile applications.
• Temperature Control: Thermostatic controls help maintain the selected operating temperature.
• Electrical Requirements: Many traditional electric sauna heaters require dedicated 240 V electrical service. Circuit and amperage requirements vary by heater model and installation. Always follow the manufacturer's specifications and use a licensed electrician in accordance with applicable electrical codes.

Wood-Burning Sauna Stoves

For remote properties, cabins, or homeowners seeking a traditional sauna experience, a wood-burning sauna heater offers an alternative to electric heat.

• Off-Grid Capability: Wood-burning heaters can operate without a dedicated electrical heater connection, although other sauna components may still require electricity.
• Traditional Ambiance: Wood-burning sauna stoves provide the atmosphere and experience of a traditional wood-fired sauna.
• Installation Requirements: Proper chimney and stovepipe installation, clearances, ventilation, and compliance with applicable fire and building codes are essential.

Sizing Guide: How Much Heater Power Do You Need?

Sauna heater sizing should be based on the sauna's interior volume, insulation, glass area, outdoor climate, construction, and the heater manufacturer's specifications. Large glass surfaces and less-insulated areas may require additional heater capacity.

The following table is a general planning reference only. Always follow the specifications provided by the sauna and heater manufacturer for the particular model you are considering.

Actual heater requirements vary by sauna design, insulation, glazing, climate, and manufacturer specifications.

3. Selecting the Best Lumber & Weather Protection

An outdoor sauna may be exposed to UV radiation, rain, snow, temperature changes, and fluctuating moisture levels. Selecting appropriate materials and following the manufacturer's exterior-care recommendations can help support long-term durability.

• Canadian Red Cedar: A premium sauna wood valued for its distinctive appearance, aroma, and natural characteristics that make it well suited to sauna construction. 
• Solid Hemlock: A clean, attractive wood commonly used in sauna construction and valued for its smooth appearance and consistent grain.
• Northern European Spruce: Available in select models with chemical-free treatment and valued for its traditional appearance and suitability for sauna construction.
• Thermo Poplar: Thermally modified poplar offers enhanced dimensional stability and reduced moisture absorption, making it well suited to demanding sauna environments.
• Thermo Aspen/Alder: Thermally modified Aspen and Alder offer distinctive appearance and improved dimensional stability for select sauna designs.

Available wood species, treatments, finishes, and construction methods vary by manufacturer and model. Please refer to the individual product page for exact materials and specifications.

4. Backyard Site Preparation & Electrical Requirements

Before you buy an outdoor sauna, proper site preparation is important for safe installation and long-term performance.

• Solid, Level Foundation: Outdoor saunas should be installed on a stable, level surface appropriate for the specific model. Depending on the sauna and local conditions, suitable foundations may include a reinforced concrete pad, properly installed pavers, or a structurally adequate deck. The foundation must be capable of supporting the fully assembled sauna and its occupants.
• Dedicated Electrical Service: Many residential outdoor electric saunas require 240 V electrical service. Voltage, amperage, breaker, wiring, disconnect, and other electrical requirements vary by heater and sauna model. Review the manufacturer's specifications and consult a licensed electrician before installation.
• Weather Protection & Roof Options: Outdoor sauna roof systems vary by model. Depending on the design, weather protection may include shingles, roofing membranes, metal roofing, or other manufacturer-specified materials. Follow the manufacturer's installation and maintenance requirements to help protect the sauna from weather exposure.
• Local Requirements: Building, zoning, setback, electrical, mechanical, and other requirements vary by location. Check applicable local requirements before preparing your site or scheduling installation.

Frequently Asked Questions (FAQs)

Q1: What factors affect the price of an outdoor sauna?

The price of an outdoor sauna varies depending on size, construction, wood species, heater technology, capacity, manufacturer, and features such as panoramic glass, upgraded controls, lighting, and premium finishes.

When comparing outdoor saunas, consider not only the purchase price but also installation requirements, electrical work, foundation preparation, maintenance, warranty coverage, and included accessories.

Q2: Can an outdoor barrel sauna be used in freezing winter climates?

Many barrel sauna models are designed for year-round outdoor use, including operation in cold climates. Performance in freezing conditions depends on factors such as construction, wood thickness, heater capacity, insulation, wind exposure, and the manufacturer's specifications.

Always verify the manufacturer's recommended operating conditions, installation requirements, and applicable snow-load specifications for your particular model and location.

Q3: What is the main difference between an outdoor infrared sauna and a traditional sauna?

Traditional saunas use an electric or wood-burning sauna heater to heat the surrounding air and, with compatible heaters and sauna stones, can provide increased humidity when water is appropriately added to the stones.

An outdoor infrared sauna uses radiant infrared heating elements and generally operates at lower ambient temperatures, commonly around 120°F–150°F depending on the model. Some users prefer this lower-temperature sauna experience.

Q4: How much maintenance does an exterior sauna require?

Maintenance varies by sauna construction, wood species, climate, frequency of use, and manufacturer recommendations.

Interior benches and surfaces can generally be cleaned periodically according to the manufacturer's care instructions. Exterior wood may require cleaning, staining, sealing, or other weather protection depending on the wood species and sauna design.

Always follow the manufacturer's maintenance instructions, particularly before applying stains, sealants, cleaners, or other treatments.

Q5: Do I need a building permit to install an outdoor sauna in my backyard?

Permit requirements vary significantly by location. Depending on your municipality and installation, an outdoor sauna may be subject to building, zoning, setback, electrical, mechanical, fire-safety, or other requirements.

Before installation, check with your local building department and qualified contractors regarding requirements applicable to your property and sauna.

Conclusion:

Investing in an outdoor sauna can bring warmth, relaxation, and a traditional sauna experience directly to your home. By evaluating your available space, climate, preferred sauna style, wood species, installation requirements, and sauna heater, you can create a backyard wellness retreat designed for years of relaxation and enjoyment.
