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. Allow up to 20 cm of clearance at the rear of the sauna to ensure adequate airflow and proper operation of the ventilation vents.
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 6063-T5 aluminium batten cladding exterior that is engineered to withstand UV exposure, humidity, heat and rain long term.
The roof is finished in the same aluminium cladding, with a slight pitch to shed water and a fully sealed roofline, built to stay weather resistant for years without the upkeep bitumen shingles need.
-
Every Nordhaus outdoor sauna is built to one standard: a genuine Harvia 9kW heater as standard, deep seating, premium accessories, proper insulation, and WiFi control included from day one.
The heater reaches up to 110C, and WiFi control lets you 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-insulated wall panels to help retain heat, maintain a consistent temperature, and reduce wasted electricity during use, backed by an aluminium vapour barrier that stops moisture from reaching the insulation. The exterior is finished with custom black/white 6063-T5 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, every detail is done properly from day one.
-
This sauna is fitted with a Harvia The Wall 9kW heater, which requires a dedicated 3-phase 16A connection installed by a licensed electrician. In some cases single phase may be possible via a dedicated 50A circuit, so confirm with your electrician prior to installation.
- The sauna does not include a power cable for the heater. Your electrician will supply and install appropriate cabling to suit your setup.
Harvia requires electrical components to sit in a cool part of the sauna, not the roof, where heat buildup can damage components and create a safety risk. Our saunas have no electrical components in the roof. The Harvia power box is installed under the bottom seat, inside the cabin, with an IPX5 rating (model FX1104XC), and all safety sensors are fitted to comply with AS/NZS 60335.2.53.
-
With the Harvia 9kW WiFi heater, the sauna reaches operating temperature in approximately 30 to 45 minutes. Using the MyHarvia app you can start preheating remotely so it is ready when you are.
-
Yes. The Harvia Fenix WiFi control panel connects to the MyHarvia app, allowing you to set temperature, schedule sessions and monitor your sauna from anywhere on your smartphone.
-
Minimal upkeep is required to keep your sauna in top condition:
- Wipe down the interior benches after use
- Leave the door open to air dry after each session
- Inspect the exterior cladding annually
The aluminium exterior requires no staining or sealing.
-
The Nordhaus Outdoor Traditional Sauna includes a 5-year residential warranty on the cabin and electrical components, a 2-year warranty on the Harvia heater, and 1-year coverage on accessories.
-

-
Suitable for both indoor and outdoor use, in a backyard, garage, or dedicated wellness space.
We recommend installing on a flat concrete slab or suitable pile foundation rather than directly on grass or soil, which protects the underside of the sauna and supports long-term durability.
