Overview
Room for the whole family, in a sauna designed to complement your home. The Nordhaus 4-5 Person Outdoor Traditional Sauna is wrapped in custom powder-coated aluminium batten cladding, giving it a sleek, architectural finish that stands up to Australian sun, rain and humidity, with no sanding, staining or ongoing upkeep. A fully sealed roofline keeps the weather out, so it looks as considered in five years as it does on day one.

Canadian Hemlock lines the interior, with extra-deep 50cm upper and lower benches giving everyone room to stretch out, plus warm LED lighting and 8mm tinted tempered glass.

FAQ
Everything you need to know before choosing your outdoor sauna. Still unsure? Call 0401 696 261 or email sales@nordhaus.com.au.
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 traditional sauna is built to one standard: a genuine Harvia heater (6kW in the 3 Person, 9kW in the 4-5 Person), 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.
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:
The aluminium exterior requires no staining or sealing.
For home use, the cabin, aluminium cladding and electrical components are covered for 5 years, the Harvia heater for 2 years, and the heater elements, WiFi control panel and accessories for 1 year. Commercial use is covered for 1 year. Full details are on our warranty page.

Reach us on 0401 696 261 or at sales@nordhaus.com.au.
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.
