Electrical Connection
The sauna can be assembled yourself, however the heater must be connected by a licensed electrician. This is usually a simple one time setup and is commonly completed in under an hour.
Suitable Placement
Suitable for both indoor and outdoor use. For best long term durability, we recommend installing the sauna on a flat concrete slab, tiled surface or suitable pile foundation.
Avoid Direct Ground Placement
Do not install the sauna directly on grass, soil or uneven ground, as this can affect stability, drainage and long term timber protection.

Frequently Asked Questions
Everything you need to know before choosing your outdoor Sauna
-
Yes. The Nordhaus Outdoor Traditional Sauna is built specifically for Australian outdoor conditions with a custom black aluminium batten cladding exterior that is engineered to withstand UV exposure, humidity, heat and rain long term.
-
Most outdoor saunas are built to a price, with smaller heaters, shallow seating, 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.
A three-stage airflow system helps provide the heater with enough fresh air, circulate heat throughout the cabin, and allow stale air to exhaust from the sauna. This supports more consistent heating and creates a more comfortable sauna environment.
Comfort is just as important as heat. Both the top and bottom benches are 50cm deep, giving everyone more room to sit back and relax comfortably throughout the session. The spacious two-tier layout provides a comfortable amount of room for the whole family, while allowing each person to choose their preferred heat level. Bench depth is one of the most overlooked aspects when comparing saunas, but it makes a significant difference to the overall experience.
We use non toxic PIR insulation foam to help retain heat, maintain a consistent temperature, and reduce wasted electricity during use. The exterior is finished with custom black aluminium batten cladding built for Australian conditions, meaning there is no need to sand and re-stain the sauna every six months like traditional timber cladding.
With genuine Harvia accessories included as standard, it is a sauna designed with no shortcuts, no upsells, and every detail done properly.
