Home gyms were once the main feature for homeowners interested in fitness and recovery. Today, more people are taking the idea further by creating complete wellness spaces with infrared saunas, traditional electric saunas, ice baths and dedicated recovery areas.
Home sauna installations are becoming increasingly common across Australia, including in new homes, renovations, outdoor entertaining areas and converted spare rooms.
However, there is one important part of the project that can easily be overlooked.
The sauna may arrive as a complete kit, but that does not necessarily mean it can be connected to an ordinary household power point.
Quick answer
The electrical requirements for a home sauna depend on the type of sauna, its heater, its power rating and where it will be installed.
Some smaller infrared saunas may operate from a suitable power point. Larger infrared saunas and traditional electric saunas may require a dedicated electrical circuit, specialised outlet or hardwired connection.
Before ordering a sauna, provide the electrical specifications to a licensed electrician. This allows the electrician to check the required circuit, your switchboard capacity, cable route, safety protection and installation location.
Why are more people installing saunas at home?
Homeowners are increasingly designing their homes around lifestyle, health and convenience.
Instead of travelling to a gym, wellness centre or recovery studio, a home sauna allows the owner to build the experience into their normal routine.
Common reasons people are adding saunas include:
- Creating a dedicated home recovery space
- Adding to an existing home gym
- Building an outdoor wellness area
- Combining a sauna with an ice bath or plunge pool
- Creating a quiet space for relaxation
- Adding a premium feature during a renovation
There are also more prefabricated sauna cabins available than there were previously. This has made home installation more accessible, but it has also created confusion about what electrical preparation is required.
Can a home sauna use a normal power point?
Sometimes, but not always.
Compact infrared saunas are often designed with lower electrical requirements than traditional saunas. Some models may use a standard 10-amp or 15-amp connection, depending on the manufacturer and the total power draw.
Even when a sauna has a standard plug, the existing circuit still needs to be suitable. A power point may already share a circuit with air conditioning, heating, appliances or other high-demand equipment.
Extension leads and power boards should not be used as a permanent supply for a sauna.
Larger infrared models may require a specialised outlet or dedicated circuit. Traditional electric sauna heaters generally have a considerably higher power demand and are commonly hardwired.
The correct answer always comes from the sauna manufacturer’s electrical specifications and an assessment of the home’s existing electrical system.
Infrared sauna versus traditional electric sauna
Infrared saunas
Infrared saunas use infrared panels to heat the user and the interior of the cabin. They generally operate at lower air temperatures than traditional saunas and are often available as prefabricated indoor cabins.
Smaller models may have relatively straightforward electrical requirements, while larger cabins can require a dedicated circuit or higher-capacity outlet.
Traditional electric saunas
A traditional electric sauna uses a powerful heater to warm the air and sauna stones. These heaters can place a significant load on the electrical system.
Depending on the size and heater rating, the installation may require:
- A new dedicated circuit
- A hardwired electrical connection
- Appropriately sized cabling
- Circuit breaker and safety switch protection
- An isolation method
- A switchboard assessment or upgrade
- Three-phase power for some larger systems
The electrician must follow the manufacturer’s installation instructions when selecting the circuit, protection equipment and connection method.
What does an electrician check before installing a sauna?
A sauna installation is not simply a matter of finding the closest power point.
Before completing the electrical work, the electrician may need to assess several parts of the project.
1. The sauna’s power requirements
The electrician will need the sauna model, voltage, wattage, current rating, plug type and manufacturer’s installation instructions.
This information determines whether the sauna can use an appropriate existing outlet or requires a new dedicated supply.
2. The existing switchboard
The switchboard must have enough capacity and physical space for any new circuit protection required by the sauna.
Older switchboards may need additional safety switch protection or an upgrade before a high-demand sauna heater can be connected safely.
3. The available electrical capacity
A home may already have several high-demand electrical appliances, including air conditioning, electric hot water, an oven, induction cooking, a pool pump or an electric vehicle charger.
The electrician needs to consider the sauna as part of the home’s overall electrical demand, rather than assessing it in isolation.
4. The cable route
The location of the sauna affects how the new electrical supply can be installed.
The electrician may need to run cabling through the ceiling, walls, under the floor, through conduit or underground to an outdoor structure.
Planning the cable route before the sauna is assembled can prevent unnecessary cutting, removal or rework later.
5. Heat, moisture and weather exposure
Saunas create a hot environment, while outdoor installations may also be exposed to humidity, rain and changing weather conditions.
The electrical equipment, cable placement, controls and connection points must be appropriate for the installation environment and kept clear of excessive heat and moisture.
6. Lighting and additional equipment
The heater may not be the only electrical component in the sauna area.
The project may also include:
- Internal sauna lighting
- Exterior feature lighting
- Ventilation
- Electronic controls
- Speakers or entertainment equipment
- An ice bath or plunge pool
- Nearby power points
- Outdoor pathway or security lighting
Planning these elements together usually produces a neater installation than adding them individually after the sauna has been completed.
Installing an outdoor sauna
Outdoor saunas have become popular because they can be incorporated into a backyard, pool area, patio or dedicated wellness zone.
They can also require more electrical preparation than an indoor prefabricated cabin.
An outdoor sauna installation may involve:
- Underground or protected electrical cabling
- Weather-resistant electrical equipment
- Careful positioning of controls and connection points
- Coordination with landscaping or concreting work
- Electrical planning around pools, spas or ice baths
- Exterior lighting and pathways
If an outdoor sauna is part of a larger renovation, it is worth involving the electrician before the structure, deck or landscaping is finished.
Check the sauna’s electrical compliance before buying
Homeowners should be particularly careful when purchasing sauna equipment directly from an overseas supplier.
A sauna heater or infrared cabin designed for another country may use a different plug, voltage, wiring arrangement or certification system.
Before purchasing, ask the supplier for:
- The complete electrical specification sheet
- The installation manual
- The power rating and required circuit
- The plug or hardwiring requirements
- Evidence that the electrical equipment is approved for use in Australia
A licensed electrician may be unable to connect equipment that does not meet Australian electrical safety requirements.
Why should the electrician be involved before the sauna arrives?
Contacting an electrician early can help prevent several common problems.
These include ordering a sauna that:
- Requires more power than the existing installation can comfortably supply
- Needs a circuit that was not included in the project budget
- Cannot be connected to the intended power point
- Requires a switchboard upgrade
- Uses equipment that is not approved for Australian installation
- Is positioned somewhere difficult or expensive to cable
In many cases, running the circuit before the sauna is assembled makes the final connection faster, cleaner and easier.
Can a home solar system power a sauna?
A solar system may help offset the electricity used by a sauna, particularly when the sauna is operated during daylight hours.
However, having solar panels does not change the sauna’s electrical installation requirements. The sauna still needs the correct circuit, cabling, protection and connection method.
The amount of solar energy available will also depend on the size of the solar system, household consumption, weather conditions and the sauna heater’s power demand.
