The Complete Infrared Sauna Buyer's Guide for Australian Homes
Learn how infrared saunas work, their potential benefits, running costs, installation requirements and what you should compare before buying a sauna in Australia.
Published by Torquay Saunas · 30 August 2026 · 15 min read
Buying a sauna is a significant decision. Done well, it creates a private wellness space you'll use for years. Done poorly, it becomes an expensive piece of outdoor furniture that doesn't perform as expected.
This guide covers everything an Australian buyer needs to know before purchasing an infrared sauna — from how the technology works, to running costs, installation requirements, what to look for in a product, and the questions worth asking before you commit.
It is written by the team at Torquay Saunas, a specialist outdoor sauna retailer based on the Surf Coast of Victoria. We sell a focused range of outdoor infrared saunas and help customers plan, purchase and install them.
What is an infrared sauna?
An infrared sauna is a timber cabin fitted with infrared heating elements. Rather than heating the air to very high temperatures as a traditional Finnish sauna does, infrared heaters emit radiant heat that warms the body more directly.
Infrared saunas typically operate at lower air temperatures — commonly between 45°C and 65°C — compared to traditional saunas which often run at 80°C to 100°C or higher. Many users find the lower air temperature more comfortable, particularly for longer sessions.
The cabin itself is usually constructed from timber — commonly hemlock, poplar, red cedar or similar species — with infrared heating panels mounted on the walls and sometimes the floor or ceiling.
Infrared versus traditional saunas
Understanding the difference between infrared and traditional saunas helps you choose the right product for your home and lifestyle.
| Feature | Infrared sauna | Traditional sauna |
|---|---|---|
| Heating method | Infrared radiant heat | Heated air (convection) |
| Typical air temperature | 45°C – 65°C | 80°C – 100°C+ |
| Heat-up time | 10 – 20 minutes | 30 – 60 minutes |
| Humidity | Low (dry heat) | Variable (steam/löyly possible) |
| Power consumption | Generally lower | Generally higher |
| Installation complexity | Typically simpler | More complex (often requires ventilation) |
| Outdoor suitability | Available in outdoor-rated models | Possible but less common |
| Session feel | Gentler, lower air temp | Intense, high air temp |
Note: specifications vary between models and manufacturers. Always confirm with the supplier before purchasing.
Potential benefits of infrared sauna use
Research into infrared sauna use is ongoing. The following are commonly reported or studied areas of interest. This is not medical advice, and infrared saunas are not a treatment for any medical condition.
- Relaxation: Regular sauna sessions are widely associated with relaxation and stress reduction. Many users incorporate sauna use into a wind-down routine.
- Muscle recovery: Heat therapy is commonly used by athletes and active individuals as part of a post-exercise recovery routine. Some research suggests heat may support muscle relaxation and recovery.
- Sleep: Some users report improved sleep quality when sauna use is incorporated into an evening routine, though individual results vary.
- Circulation: Heat exposure causes blood vessels to dilate, which may support circulation. Research in this area is ongoing.
- Skin: Sweating during sauna use may support skin cleansing. Individual results vary.
Far infrared and full-spectrum infrared explained
Infrared light exists on a spectrum. In the context of saunas, you will commonly encounter three terms:
Far infrared (FIR)
The most common type used in home saunas. Far infrared wavelengths are at the longer end of the infrared spectrum and are associated with deep, penetrating radiant heat. Most entry-level and mid-range infrared saunas use far infrared heaters.
Near infrared (NIR)
Shorter wavelengths, sometimes associated with skin and surface-level effects. Less common in standard home saunas.
Full spectrum
A sauna that combines near, mid and far infrared wavelengths. Full-spectrum saunas are typically positioned as premium products. Whether the additional wavelengths provide meaningful additional benefit for the average home user is a matter of ongoing research.
The Torquay DUO combines traditional sauna heating with far infrared technology, giving users the option to use either heating mode or both simultaneously.
Purchase costs: what to expect in Australia
Infrared sauna prices in Australia vary significantly depending on size, timber quality, heater type, features and brand. As a general guide:
| Category | Approximate price range | Typical features |
|---|---|---|
| Entry level (1–2 person) | $1,500 – $3,500 | Basic heaters, limited controls, indoor-only |
| Mid range (1–2 person) | $3,500 – $7,000 | Better timber, improved heaters, some features |
| Premium (2–4 person) | $7,000 – $15,000+ | Quality timber, full features, outdoor-rated options |
Price ranges are indicative only and subject to change. Contact Torquay Saunas for current pricing on our range.
Beyond the purchase price, budget for delivery, any site preparation (concrete pad, decking), electrical connection by a licensed electrician, and ongoing running costs.
Flexible finance through HUMM may allow eligible customers to spread the cost over time. Finance is subject to credit assessment and applicable terms.
Running costs
Infrared saunas are generally more energy-efficient than traditional saunas. Running costs depend on:
- The power rating of the sauna (measured in watts or kilowatts)
- How long each session runs
- How frequently you use it
- Your local electricity tariff
Running cost calculation example
Example: Torquay DUO (2,800W / 2.8kW)
- Power: 2.8 kW
- Session length: 45 minutes (0.75 hours)
- Energy per session: 2.8 × 0.75 = 2.1 kWh
- Electricity rate: ~$0.30/kWh (varies by provider and state)
- Cost per session: 2.1 × $0.30 ≈ $0.63
- Weekly (5 sessions): ≈ $3.15
- Annual (5 sessions/week): ≈ $163
This is an illustrative example only. Actual costs depend on your electricity tariff, usage patterns and whether the sauna reaches full power for the entire session. Check your electricity bill for your current rate.
The Torquay ONE (1,800W) will cost less to run per session than the larger Torquay DUO (2,800W) or Torquay FOUR (2,800W).
Indoor installation
Many infrared saunas are designed for indoor installation — in a bathroom, spare room, garage or dedicated wellness space. Key considerations for indoor installation include:
- Sufficient ceiling height (most saunas are 2,100mm tall)
- Adequate floor space with clearance around the unit
- A level, solid floor capable of supporting the sauna's weight
- Proximity to an appropriate electrical circuit
- Ventilation to manage heat and moisture in the surrounding room
- Access for delivery and assembly
Not all infrared saunas are suitable for outdoor use. If you intend to install a sauna outdoors, confirm with the supplier that the specific model is rated and warranted for outdoor installation.
Outdoor installation
Outdoor sauna installation requires more planning than indoor installation, but the result — a private wellness space in your own backyard — is one of the most popular home improvements for Australian homeowners.
The Torquay Saunas range is designed specifically for outdoor installation. Key considerations include:
Foundation
The sauna must sit on a stable, level surface capable of supporting its weight. Suitable foundations include:
- Concrete slab (most common and recommended)
- Suitable paving on a solid base
- Appropriately engineered decking
The foundation must be level. An unlevel sauna can affect door operation, drainage and long-term structural integrity.
Electrical supply
Outdoor saunas require a dedicated electrical circuit. Electrical requirements vary by model — confirm the specific requirements for your chosen sauna before planning your installation. Any electrical work that legally requires a licensed electrician in your state must be completed by one.
Clearances and access
- Allow clearance around the sauna as specified by the manufacturer
- Consider access for delivery — gate widths, steps, tight driveways
- Consider privacy from neighbours
- Consider drainage away from the sauna base
Common outdoor locations
- Beside a swimming pool
- Next to an ice bath or cold plunge
- On a deck or patio
- In a landscaped garden
- In an outdoor entertaining area
- In a dedicated backyard wellness zone
See our installation guide for more detail on site preparation, delivery and what to expect on installation day.
Surf Coast, Torquay, Geelong and Bellarine considerations
Customers in the Surf Coast, Torquay, Geelong and Bellarine Peninsula regions have some specific considerations when planning an outdoor sauna installation.
Coastal conditions
Coastal environments expose outdoor structures to salt air, higher humidity and stronger winds. When selecting a sauna for a coastal location:
- Confirm the sauna's suitability for coastal or marine environments with the supplier
- Consider the timber species and its resistance to moisture and salt air
- Plan for regular maintenance to protect the timber exterior — see our outdoor infrared sauna maintenance guide
- Consider the orientation of the sauna relative to prevailing winds
Year-round use in Victoria
Victoria's climate — including cold winters on the Surf Coast — makes year-round sauna use genuinely practical. Many customers find the sauna most valuable during cooler months, when stepping from a warm sauna into the cool outdoor air is particularly enjoyable.
Pool zone electrical requirements
If your sauna will be installed near a swimming pool, specific electrical safety zones apply under Australian standards. Your licensed electrician must assess the installation location relative to the pool boundary. Discuss this with your electrician and with Torquay Saunas before finalising the installation site. See our installation page for more information.
Electrical safety and Australian compliance
All electrical work associated with your sauna installation must comply with Australian standards and applicable state regulations. Key points:
- Any electrical connection work that legally requires a licensed electrician must be completed by one
- Your electrician should assess the required circuit, cable run, switchboard capacity and any pool zone requirements
- Confirm the sauna's electrical specifications (voltage, amperage, circuit breaker requirements) with the supplier before your electrician visits
- Ensure the sauna complies with applicable Australian electrical safety standards
- Obtain a Certificate of Electrical Safety where required in your state
Torquay Saunas can provide the electrical specifications for each model to assist your electrician's planning. Contact us before finalising your installation site.
What to compare before buying
Not all infrared saunas are equal. Here is what to look at when comparing products.
Cabin size
Consider both the number of people who will use the sauna and the available space in your home or backyard. A 1-person sauna is compact and suits individual use; a 2-person sauna allows couples or friends to use it together; a 4-person sauna suits families or those wanting more interior space.
Check the external dimensions carefully — not just the interior. The Torquay ONE measures 1200 × 1050 × 2100mm; the Torquay DUO and Torquay FOUR are 1600 × 1200 × 2100mm.
Timber and construction
Common timber species used in infrared saunas include hemlock, poplar, red cedar and spruce. Each has different characteristics in terms of appearance, durability, moisture resistance and scent. For outdoor installations, the quality of the exterior finish and construction is particularly important.
Look for solid construction, quality joinery and a roof design suited to outdoor use. The Torquay Saunas range features an outdoor pent roof design.
Heater coverage
The number, placement and power of infrared heaters affects how evenly and effectively the cabin heats. Look for heaters positioned to provide coverage across the seating area, not just concentrated in one location.
Controls
Modern infrared saunas typically include a digital control panel for temperature and timer settings. Higher-end models may include Bluetooth audio, FM radio, USB charging, ambient lighting and smartphone connectivity. The Torquay DUO features the AV1 intelligent control system with Bluetooth, FM, USB and integrated speakers.
Electrical requirements
Confirm the voltage, amperage and circuit requirements for any sauna you are considering. This affects the cost and complexity of your electrical installation. Ensure your home's switchboard can accommodate the additional circuit.
Warranty
Understand what is covered and for how long. Torquay Saunas provides a 5-year structural warranty. Ask the supplier to clarify exactly what the warranty covers — structural components, heaters, controls and timber — and what conditions apply.
Delivery and assembly
Confirm what is included in the purchase price. Does delivery include placement at the installation site? Is assembly included or is it a flat-pack? What access is required? Torquay Saunas provides delivery options and can advise on access requirements. See our installation page for details.
Safe sauna use
Infrared saunas are generally considered safe for healthy adults when used sensibly. The following guidelines are commonly recommended:
- Stay hydrated — drink water before, during and after your session
- Start with shorter sessions (15–20 minutes) and lower temperatures while you acclimatise
- Do not use a sauna if you are feeling unwell, have a fever, or have consumed alcohol
- Exit the sauna immediately if you feel dizzy, nauseous or unwell
- Allow time to cool down gradually after each session
- Do not leave children unattended in a sauna
- Consult your doctor before use if you are pregnant, have cardiovascular conditions, low blood pressure, or are taking medication that affects heat tolerance
Always read and follow the manufacturer's safety instructions supplied with your sauna.
