Do You Need An Electrician to Install Sauna Electrical Components?
Traditional saunas require significant power, typically 240V, and must be hardwired into your electrical system. This involves setting up a dedicated circuit to handle the high power demands, ensuring the sauna operates without overloading your home’s electrical system.
Installing a sauna requires attention to the power needs, compliance with electrical standards, and the involvement of a licensed electrician. This guide focuses on traditional saunas and highlights the electrical requirements necessary to ensure a safe and reliable setup.
Electrical Requirements for Traditional Saunas
Traditional saunas typically require a high-power supply, usually 240V. These saunas rely on electric heaters, which can range from 4.5kW to 9.0kW depending on the model and size.
The electrical systems in most homes are not equipped to handle this level of power directly, so the sauna must be hardwired into the electrical system. This process involves setting up a dedicated circuit, which ensures that the sauna has a direct power line without sharing electricity with other devices in the home.
For heaters rated 4.5kW to 6.0kW, a 30-amp breaker is required, along with 10/2 gauge wire. The 10/2 wire is designed to handle the current load safely. For heaters rated 8.0kW, the power demand is higher, so a 40-amp breaker and 8/2 gauge wire are required. These configurations ensure the sauna operates without overloading the home’s electrical system, which could otherwise result in electrical fires or system malfunctions.
Breaker and Wire Requirements for Sauna Heaters

In Australia, all electrical installations, including sauna wiring, must comply with the AS/NZS 3000:2018 (Wiring Rules), which is the standard for electrical installations. This standard outlines the specifications for selecting the appropriate circuit breakers, wiring, and protection devices based on the appliance’s power consumption.
- Circuit Breakers: These are necessary to protect the sauna circuit from overloading. If the sauna draws more power than the circuit can handle, the breaker will trip, cutting off power and preventing damage or fire. The size of the breaker depends on the sauna heater’s power rating. For example, a 30-amp breaker is sufficient for heaters up to 6.0kW, while larger heaters, such as 8.0kW, require a 40-amp breaker.
- Wiring: The 10/2 gauge wire is commonly used for appliances that require up to 30 amps of current, while the 8/2 gauge wire is used for systems requiring up to 40 amps. The “/2” refers to two insulated conductors and one bare ground wire, typically used in high-power systems like electric heaters.
Electrical Safety and Compliance
All sauna installations in Australia must be performed by a licensed electrician in compliance with the Australian Building Code. Not complying with these standards can lead to serious hazards, such as electrical shock, fire, and malfunctioning equipment, and may also void the warranty on your sauna or result in legal penalties.
It’s important to ensure proper wiring insulation and the use of appropriate circuit breakers. Regular maintenance checks by an electrician are recommended to ensure the electrical components of the sauna remain in safe working condition over time. Overloading circuits or using improper wiring can lead to significant risks, including overheating and electrical fires.
Moreover, the AS/NZS 3000:2018 also requires the installation of Residual Current Devices (RCDs) or Ground Fault Circuit Interrupters (GFCIs) for added protection, especially in areas with high moisture, such as saunas. These devices detect any electrical leakage and automatically cut off power to prevent electrocution.
RCD Protection/ GFCI for Saunas
Saunas should have Residual Current Device (RCD) protection to enhance safety. An RCD, also known as a Ground Fault Circuit Interrupter (GFCI), helps prevent electrical shocks by immediately cutting off power if it detects that electricity is flowing through an unintended path, such as water or a person. Since saunas involve heat and humidity, having RCD protection is crucial for preventing electrical hazards.
Installing an RCD is generally required in Australia and other countries to comply with electrical safety regulations, and it is especially important in environments like saunas, where moisture levels are high.

How Much Does It Cost to Run a Sauna in Australia?
The cost of running a sauna in Australia depends on the size of the sauna, the type of heater, and how frequently it is used. For traditional saunas, which typically run on 240V and consume between 4.5kW to 8.0kW, the cost can vary depending on how often and how long you use your sauna. Here’s an example:
Let’s assume a sauna with 6 kilowatts (kW) operating on 240 volts (V). For the the usage:
- Frequency: 2 times per week
- Duration per Session: 15 minutes (0.25 hours)
- Heating Time per Session: 1 hour
- Monthly Sessions: 2 sessions/week × 4 weeks=8 sessions/month
Calculate Energy Consumption: For each session, there are two components to consider: heating period and actual sauna use.
a. Energy Use for Heating:
Power (kW)×Heating Time (hours)= Energy use for heating
6 kW ×1 hour = 6 kWh/session
b. Energy Use for Usage:
Power (kW) × Usage Time (hours)= Energy Use for Usage
6 kW × 0.25 hours = 1.5 kWh/session
c. Total Energy Use per Session:
6 kWh (heating) + 1.5 kWh (usage) =7.5 kWh/session
d. Monthly Energy Use:
7.5 kWh/session × 8 sessions = 60 kWh/month
Calculate Monthly Cost: Assume average electricity rate in Australia, approximately $0.30 per kWh (rates may vary based on provider and location)
Monthly Cost= Monthly Energy Use × Electricity Rate
60 kWh × $0.30/kWh= $18.00 per month
Monthly Cost to Run a 6kW Traditional Sauna: Approximately $18.00
The larger the sauna and the more powerful the heater, the higher the running costs. Factors such as the insulation of the sauna, frequency of use, and local electricity rates also play a significant role in determining the cost.
