Home Installation and Space Planning for Infrared Saunas

Installing an infrared sauna at home is considerably simpler than installing a traditional steam sauna, but proper planning ensures you get the most from your investment. This guide covers everything from measuring your space to electrical requirements, helping you prepare for a smooth installation whether you're doing it yourself or hiring professionals.

Choosing Your Location

The right location balances practical requirements with lifestyle considerations:

Popular Installation Locations

• Spare bedroom: Excellent choice if available—climate-controlled, convenient, and private.
• Garage: Popular in Australia. Ensure it's insulated if you plan to use it year-round, and consider security and accessibility.
• Bathroom: Convenient for showering afterward, but verify you have adequate space beyond the wet areas.
• Basement/Rumpus room: Good for temperature stability and keeping the sauna out of main living areas.
• Outdoor covered area: Possible for weather-resistant models, but consider security and weather protection.

Location Requirements

• Level floor: The sauna must sit on a flat, stable surface. Minor unevenness can be corrected with shims, but significant slopes are problematic.
• Solid flooring: Concrete, tile, hardwood, and laminate are all suitable. Thick carpet may need to be removed or protected.
• Access to power: Proximity to an electrical outlet (or feasibility of installing one) is essential.
• Ventilation potential: While infrared saunas don't produce steam, some air circulation is beneficial.
• Door clearance: Ensure there's room for the sauna door to open fully.

Space Requirements

Sauna Footprint

Infrared saunas come in various sizes. Common footprints include:

• 1-person saunas: Approximately 90cm x 90cm to 100cm x 100cm
• 2-person saunas: Approximately 120cm x 100cm to 140cm x 120cm
• 3-person saunas: Approximately 150cm x 120cm to 170cm x 130cm
• 4+ person saunas: Approximately 180cm x 150cm and larger

Additional Clearance

Beyond the sauna's footprint, allow:

• 15-20cm on each side: For air circulation and preventing heat damage to walls
• Door swing space: Typically 60-90cm in front of the door
• Overhead clearance: Most saunas are 180-200cm tall. Standard 240cm ceilings provide adequate clearance.

Electrical Requirements

Power Consumption

Most infrared saunas designed for home use operate on standard Australian 240V power. Typical power consumption:

• 1-person saunas: 1,000-1,500 watts
• 2-person saunas: 1,500-2,100 watts
• Larger saunas: 2,000-3,000+ watts

Standard Outlet Compatibility

Many infrared saunas can plug into a standard 10-amp Australian power outlet. However, check the manufacturer's specifications—some larger models require a 15-amp or 20-amp circuit.

Dedicated Circuit Considerations

Even if your sauna can technically run on a shared circuit, a dedicated circuit is recommended because:

• It prevents tripping circuit breakers when other appliances are running
• It reduces the risk of overloading older wiring
• It ensures consistent power delivery to the sauna

Extension Cord Warning

Most manufacturers strongly advise against using extension cords with infrared saunas. The high power draw can cause overheating in cords not rated for continuous high loads. If your outlet isn't close enough, have an electrician install a new outlet rather than using an extension cord.

Ventilation

Infrared saunas don't produce steam, so they don't require the same ventilation as traditional saunas. However, some air circulation is beneficial:

Natural Ventilation

• Cracks around doors and windows typically provide adequate passive airflow
• Many infrared saunas have built-in vents that allow fresh air exchange
• Leave the sauna door open after sessions to allow moisture from sweat to dissipate

When Extra Ventilation Helps

Consider improving ventilation if:

• The room has no windows or doors to outside areas
• You notice condensation forming on walls or windows
• The room feels stuffy after sessions
• You're installing in an enclosed space like a closet

Ventilation Solutions

• A simple ceiling or wall-mounted exhaust fan
• An openable window
• Leaving the door to an adjacent, ventilated room open

Floor Protection

Heat Considerations

Infrared saunas don't generate extreme floor heat like traditional saunas, but some protection may be advisable:

• Carpet: Place a protective mat under the sauna to prevent compression marks and protect from any moisture. Some owners remove carpet under the sauna entirely.
• Hardwood: Generally fine without protection, but a mat can catch sweat drips and protect the finish.
• Tile/concrete: No protection needed, though a mat can make cleaning easier.

Moisture Management

Even though infrared saunas don't create steam, sweat happens. Consider:

• A water-resistant mat just outside the sauna door for stepping out
• Easy-to-clean flooring in the immediate area
• Good towel use during sessions minimises floor moisture

Assembly and Setup

DIY vs Professional Installation

Most infrared cabin saunas are designed for DIY assembly. Typical characteristics:

• Pre-built panels that connect together
• Buckle, clip, or screw connections
• Pre-wired electrical components
• Assembly time of 30-90 minutes for two people

Professional installation is worth considering if:

• You need electrical work done simultaneously
• The sauna is very large or heavy
• You're not comfortable with basic DIY tasks
• Access to the installation location is difficult

Assembly Tips

• Have two people: Panels are manageable alone but much easier with a helper
• Read instructions completely before starting
• Clear the installation area of furniture and obstacles
• Have tools ready: Usually just a screwdriver or drill
• Check all components before assembly to identify any shipping damage
• Allow ventilation time: New saunas may have manufacturing odours. Run the sauna empty for a few sessions before regular use.

Australian Climate Considerations

Hot Weather Use

During Australian summers, consider:

• Installing in an air-conditioned room for comfortable pre/post-session environment
• Using the sauna in early morning or evening when ambient temperatures are lower
• Ensuring good hydration practices in hot weather

Garage Installations

Garages are popular but require consideration:

• Summer heat: Uninsulated garages can become extremely hot. The sauna will work, but the surrounding environment may be uncomfortable.
• Winter cold: The sauna heats quickly, but stepping out into a cold garage may be uncomfortable. Consider space heaters or insulation.
• Security: Ensure your garage is secure if the sauna will be accessed when the main house is unoccupied.

Cost Considerations

Beyond the sauna purchase price, budget for:

• Electrical work: $200-$800 for a new dedicated circuit (if needed)
• Floor protection: $50-$200 for mats or flooring modifications
• Delivery: Often included, but verify—some brands charge extra
• Professional assembly: $150-$400 if not DIY
• Ongoing electricity: Approximately $1-3 per session depending on duration and local rates

Final Checklist Before Ordering

• Measured installation space with clearances accounted for
• Verified electrical outlet availability and capacity
• Confirmed path for delivery (doors, stairs, hallways are wide enough)
• Considered floor protection needs
• Evaluated ventilation in the chosen room
• Checked warranty and return policies
