This sauna is fitted with a Harvia The Wall 9kW heater. Due to the higher power requirements, most Australian installations will require a dedicated 3 phase 16A connection installed by a licensed electrician.
In some cases, single phase may be possible, however this typically requires a dedicated 50A circuit and should be confirmed with your electrician prior to installation.
Please note, the sauna does not include a power cable for the heater. Your electrician will need to supply and install the appropriate cabling to suit your setup and local electrical requirements.
The LED lighting operates separately via a standard 10 Amp power plug, which comes pre-installed with the sauna.

Most outdoor saunas are built to a price, with smaller heaters, generic accessories, basic insulation, and WiFi sold as a paid upgrade. We do things differently. Each Nordhaus outdoor sauna includes a genuine Harvia 9kW heater as standard, delivering powerful heat suited to outdoor conditions and the ability to reach up to 110C. WiFi control is also included, allowing you to set your desired temperature and preheat the sauna remotely before you step inside. We use non toxic PIR insulation foam to help retain heat, maintain a consistent temperature, and reduce wasted electricity during use. Finished with custom black aluminium batten cladding built for Australian conditions and genuine Harvia accessories included as standard, it is a sauna designed with no shortcuts, no upsells, and every detail done properly.
