Infrared Sauna Information: What To Know Before You Buy
Understanding infrared sauna technology
Before diving into the specifics of choosing your sauna, it’s worth understanding what makes infrared saunas different from traditional alternatives. Infrared saunas employ infrared light to directly heat your body rather than heating the surrounding air. This approach allows for deeper tissue penetration and a more efficient sweat session, all whilst operating at much lower, more comfortable temperatures than traditional steam saunas.
The technology is remarkably accessible for home use. Unlike traditional saunas that require complex drainage and ventilation systems, infrared saunas are dry rooms that typically need only a standard 10-amp power point. This simplicity makes them ideal for home installation, whether you’re placing one in a spare bedroom, basement, or home gym.
Understanding heating technology and heater placement
Not all infrared saunas are created equal, and the heating technology used significantly impacts your experience. Two of the most popular options are infrared heating panels and ceramic heaters, each offering distinct advantages.
Infrared heating panels are commonly made from carbon-composite materials and typically integrated as large, flat surfaces into the cabin’s walls. These panels emit infrared radiation evenly across their surface, creating consistent heat that directly penetrates and warms your entire body. They operate at lower surface temperatures (27-60°C), produce minimal maintenance requirements, and typically last 50,000 to 100,000 hours. High-quality panels emit far-infrared radiation in the optimal 6-14 micrometre range, most beneficial to the human body.
Ceramic heaters represent an earlier heating technology, typically made of ceramic rods, plates, or tubes. Whilst they heat up quickly and operate at higher intensities, they’re smaller and create localised heat concentration. This can leave some body parts inadequately warmed, resulting in temperature variations. Ceramic heaters also operate at much higher surface temperatures (300-700°C) and have shorter lifespans, averaging around 5,000 hours of use.
Heater placement is critical since infrared saunas heat your body directly. The more efficiently heaters target your body, the faster you’ll sweat. Look for saunas with comprehensive coverage, including heaters positioned on the front wall and alongside seating areas. Many competing brands fail to install heaters on the front wall or stop side wall heaters short of the seat front, leaving the front of your body without adequate radiant heat.
Premium models should feature high-watt density carbon panels strategically positioned to provide 360-degree infrared coverage, ensuring even heat distribution across your entire body without creating cold spots.

Emissivity and infrared heat quality
Emissivity represents how effectively a material emits infrared radiation, quantified on a scale of 0 to 1, with 1 being the highest. Higher emissivity materials produce more infrared radiation, and in infrared saunas, this translates to superior therapeutic benefits.
High-emissivity panels ensure infrared rays penetrate deeply into your body, reaching intended tissues and cells. This deep heat stimulates therapeutic effects, including improved blood flow, cellular repair, and increased cardiovascular health. High-emissivity panels also emit consistent levels of infrared radiation across their surface, preventing the ‘cold spots’ often created by low-emissivity alternatives.
Energy efficiency improves significantly with high-emissivity panels, as they more effectively convert electric power into infrared heat. This reduces energy waste and lowers your long-term operational costs whilst maintaining optimal performance. Strategically positioned high-emissivity panels ensure your entire body receives equal levels of deep penetrating heat, maximising your investment returns.
Look for saunas featuring high-watt density carbon panels that concentrate infrared energy, resulting in stronger, hotter infrared output that warms your body more efficiently. Strategic heater placement around the room, including the back of the door, ensures effective heat absorption by your skin and deeper penetration into muscles and tissues.

Choosing the perfect infrared sauna for your home and lifestyle
Indoor versus outdoor infrared saunas
Your first major decision involves where you want to place your sauna. Both indoor and outdoor infrared saunas offer similar heat benefits, yet each comes with distinct advantages and considerations.
Indoor saunas are typically integrated into your home’s existing structure or set up as free-standing units. They offer year-round convenience, requiring minimal maintenance thanks to being sheltered from the elements. Installation is straightforward, and privacy is assured. However, custom features may be limited by available space within your home.
Outdoor saunas present an entirely different proposition. Free from spatial constraints, they can be larger, accommodate more people, and be highly customised to match your landscape design. The natural ventilation and fresh air exposure enhance the overall experience. The trade-off is higher maintenance requirements due to weather exposure, less privacy unless your property is secluded, seasonal usage limitations, and typically higher upfront costs.

Selecting the right size for your needs
Size isn’t just an aesthetic consideration—it directly impacts comfort, installation requirements, energy costs, and how often you’ll actually use your sauna. Getting this decision right is fundamental to long-term satisfaction.
A sauna that’s too small feels cramped, particularly when sharing sessions with partners or family members. Too large and it dominates your space, heats inefficiently, and increases energy consumption. The thermal efficiency of infrared saunas depends significantly on size-to-user ratios, where smaller units create more intimate heat distribution, whilst larger spaces may develop temperature variations that affect the therapeutic experience.
For space planning, allow a minimum of 15 centimetres clearance on all sides for proper ventilation. A 1-person sauna typically requires 2-3 square metres, 2-person units need 3-4 square metres, 3-person models require 4-6 square metres, and family units demand 6-8+ square metres. Corner installations can reduce these requirements, and a 3 by 3 metre spare bedroom comfortably accommodates a 2-person sauna with changing space.
Consider your intended usage patterns carefully. Solo users seeking daily meditation or recovery sessions suit compact 1-person units. Couples prefer intimate 2-person models for shared relaxation, whilst families or those who entertain need 3-4 person capacity. Remember that infrared saunas operate at comfortable temperatures between 45-65°C, making shared sessions enjoyable even for those with different heat tolerances.
Future-proofing your purchase matters too. Anticipate potential lifestyle changes like growing families, ageing parents who might benefit from therapy, or friends wanting to join sessions more frequently than expected.

Key safety and construction features
Your health and safety should be paramount when evaluating infrared saunas. Several critical features distinguish quality products from cheaper alternatives that might compromise your wellbeing.
Electromagnetic field (EMF) and extremely low frequency (ELF) exposure are genuine concerns. Some users worry about their exposure to these emissions, particularly those with compromised immunity. Seek saunas with ultra-low EMF and ELF heater technology. Industry-leading options measure under 2 milliGauss of magnetic fields and have minimal electric field exposure.
Construction materials matter significantly. Look for units built with 100% premium Canadian Hemlock wood, avoiding cheaper alternatives using plywood or inferior timber. Canadian Hemlock offers superior durability, natural moisture resistance, and hypoallergenic properties essential for a safe sauna environment. Avoid Western Red Cedar, which, whilst aesthetically appealing, can cause allergic reactions, respiratory issues, and skin irritation in sensitive individuals due to its chemical compounds.
The glue used in construction directly affects your health. Many infrared saunas use standard wood glues that can off-gas when heated. Premium models use food-safe, water-based glues like Titebond, which are FDA-approved for food contact and eliminate concerns about toxic emissions.
Heater construction also matters. Over 90% of competing infrared sauna brands use synthetic cloth covers on their carbon panel heaters. These covers significantly reduce infrared heat output, introduce potentially off-gassing glues and synthetic fabrics into your sauna environment, and make proper cleaning nearly impossible. High-quality saunas feature uncovered heater panels for maximum infrared emission and superior hygiene.

Comparing infrared and steam saunas
Understanding the differences between infrared and steam saunas helps determine which suits your needs. Infrared saunas heat your body directly using infrared light rather than heating the surrounding air. This approach allows operation at lower, more comfortable temperatures (45-60°C) whilst delivering deeper heat penetration for enhanced muscle relaxation and detoxification.
Steam saunas use water vapour to heat the entire room, creating moist heat that particularly benefits skin health and respiratory conditions. Steam saunas operate at higher temperatures (70-100°C) and provide surface-level heating rather than deep tissue penetration.
The choice often comes down to personal preference and specific health goals. Infrared saunas excel at muscle relief and detoxification, whilst steam saunas offer superior skin health and respiratory benefits. Many wellness enthusiasts find infrared saunas more comfortable for regular use due to lower operating temperatures, making extended sessions more enjoyable.

Finding the perfect sauna model for your lifestyle
With numerous models available, identifying the right option depends on your specific circumstances. Budget-conscious individuals seeking space efficiency benefit from compact 1-person units offering powerful performance in a minimal footprint. These models deliver the same premium features as larger options—360° infrared heat, Bluetooth speakers, and customisable intensity controls—at significantly lower costs.
Couples often prefer intimate 2-person models providing 360-degree infrared body coverage with adequate space for two to enjoy sessions together. These models typically feature sweat-resistant backrests and customisable heat intensity, accommodating different preferences within a shared session.
Families or those entertaining regularly benefit from larger 3-4 person models offering ample room to spread out and truly unwind. These spacious options provide multiple seating configurations, extensive chromotherapy lighting, and comfortable space for guests to experience wellness benefits together.
Preparing for your new infrared sauna
Electrical safety and certification
Proper electrical certification ensures your sauna operates safely and meets Australian standards. Very few sauna companies can provide legitimate electrical certification, so this is a critical differentiator.
All quality infrared saunas should be built to joint electrical safety standard AS/NZS 60335.1:2020, created by Standards Australia and Standards New Zealand. This certification ensures electrical components have been properly tested and the system operates safely within your home.
Most infrared saunas require standard 10-amp power points, though larger models may need dedicated circuits installed by licensed electricians. Factor any necessary electrical upgrades into your budget planning before purchase. Avoid using extension cords, which pose overheating risks—if electrical upgrades are necessary, complete these before installation day.

Warranty and customer support
With any product featuring working parts and electronics, the risk of breakdowns exists. A comprehensive warranty protects your investment and indicates manufacturer confidence in their products.
Quality manufacturers stand behind their offerings with extensive warranty coverage. Premium brands offer residential lifetime warranties covering the entire sauna—heaters, electronic control systems, cabinets, light bulbs, and all other components. This coverage demonstrates both product quality and genuine commitment to customer satisfaction.
Beyond warranty terms, evaluate the quality of customer support available. Reputable manufacturers provide reliable after-sales service, helping you navigate any issues that might arise and ensuring your sauna continues delivering benefits for years to come.

Flooring and installation considerations
Selecting appropriate flooring significantly impacts your sauna’s longevity and user experience. Wooden floors using cedar or Canadian Hemlock provide warmth and comfort whilst maintaining the natural aesthetic. Ceramic or porcelain tiles offer excellent water resistance and easy maintenance, with the option for underfloor heating systems. Concrete or stone flooring delivers exceptional durability and simple upkeep. Budget-conscious buyers might consider vinyl flooring, which provides waterproof protection and slip resistance at affordable costs.
For stability, ensure a flat, level surface that can support the sauna’s weight. Allow a minimum of 3 centimetres clearance on all sides for ventilation and maintenance access. In high-humidity environments, moisture-resistant mats or plywood sheets protect underlying flooring from sweat damage.
Unlike traditional saunas, where water is poured over rocks, dry infrared saunas typically don’t require drainage systems, particularly when installed on concrete or tile flooring. This represents a significant installation advantage for home use.

Installation preparation and planning
Successful sauna installation requires comprehensive planning extending beyond simple floor space calculations. Ensure electrical access is available—most infrared saunas require dedicated 15-20 amp circuits, with larger units needing 240V connections installed by licensed electricians.
Consider ventilation planning to prevent moisture accumulation and ensure optimal performance. Whilst infrared saunas produce minimal humidity compared to steam saunas, adequate air circulation maintains comfort and extends equipment lifespan. Think practically about installation logistics: can delivery trucks access your property? Will the unit fit through doorways and up stairs? Is there adequate space for ongoing maintenance? Will installation disrupt other room functions or household traffic patterns?
Study instruction manuals thoroughly before beginning installation. Recruit an assistant for a two-person assembly to ensure safety and efficiency. Gather all necessary tools and have them ready and accessible before starting.

Operating costs and energy efficiency
Infrared saunas have differing emissivity levels affecting their performance
One significant advantage of infrared saunas is their remarkable energy efficiency. Traditional saunas accommodating 3-5 people use approximately 9-13 kilowatt hours of power, costing roughly $5.50 per session at average Australian electricity rates. Used five times weekly, this totals approximately $1,997 annually—a 150% increase to typical household energy costs.
Infrared saunas consume substantially less power. A 3-person infrared model requiring only 15 minutes preheating and 20-30 minute sessions costs at most $0.56 per hour to operate—approximately $112.59 annually or $9.25 monthly. Smaller 1-person units cost even less, roughly $69.40 yearly or $0.19 daily.
This dramatic difference makes infrared saunas far more sustainable options for regular wellness routines. Over decades of ownership, energy savings alone can offset initial purchase costs, particularly if you use your sauna regularly.

Weatherproofing outdoor saunas
If you’re investing in an outdoor sauna, protecting it from weather conditions is essential for extending its lifespan and ensuring year-round usability. Choose a strategic location with natural shelter, such as near a wall, under a sturdy awning, or beneath a custom-built pergola. These structures shield your sauna from direct rainfall and sunlight, reducing wear and tear.
Invest in a durable, waterproof sauna cover—ideally UV-resistant and breathable to prevent moisture buildup. Apply weatherproof sealants to external wooden components to preserve their integrity and prevent warping, cracking, or fading. For harsher climates, treat exterior wood annually with weather-resistant oils or varnishes.
Ensure electrical components have waterproof enclosures around connections, that all outlets meet outdoor safety standards, and that wiring is regularly inspected for wear, corrosion, or damage. Conduct routine maintenance during seasonal adjustments, checking for excessive sunlight in summer and inspecting seals and insulation during winter.
