Dual Benches with Ambient Lighting

Dual benches offer a spacious, tiered layout so you can choose your preferred heat level, higher for more intensity, lower for a gentler session. Double-thick curved seating ensures lasting strength and everyday comfort. Paired with subtle ambient lighting, the layered design adds depth, comfort, and a refined architectural feel to your sauna.

Nordhaus Flow

Precision airflow engineered to circulate fresh air through the sauna. Cool air enters beneath the heater, rises as it warms, then exits through the upper and lower vents to maintain consistent heat and oxygen flow throughout the cabin.

Premium Sauna Accessories

Premium sauna accessories include a genuine black steel Harvia bucket, ladle and Harvia Black Vulcanite sauna rocks plus sand timer and drip tray, refined essentials that complete your sauna experience.

Harvia Fenix Wifi Sauna Controller

Preheat and operate your sauna from anywhere with the Harvia Fenix WiFi control unit, mounted on the back wall under the backrest for easy access while seated inside. Featuring Harvia’s latest control technology, Fenix combines smart connectivity, intuitive operation, and advanced safety features for a seamless sauna experience.

Ventilation That matters

An extra-large vent beneath the heater draws in fresh air and lets excess moisture drain out, while two back wall vents clear moisture after each session. There are no vents in the roof, keeping the structure protected from moisture and mould.

The Authentic Sauna Experience

From the first rush of heat to the final deep exhale, every detail is designed to restore balance, calm, and vitality - a modern take on an ancient wellness tradition.

Ritual Meets Recovery

Regular sauna sessions support muscle recovery, improve circulation, and promote better sleep, helping you feel grounded, recharged, and ready for what’s next.

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.

    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 6kW 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 supply 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 a more comfortable sauna environment.

    The top bench is 50cm deep, giving you more room to sit back and remain comfortable throughout your sauna session. 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 aluminium batten cladding built for Australian conditions, meaning there is no need to sand and restain the sauna every six months like traditional timber cladding.

    With genuine Harvia accessories included as standard, every detail is done properly from day one.

  • Harvia recommends a 35 Amp dedicated circuit installed by a licensed electrician.

    • The heater cable is not included and must be supplied by your electrician
    • Your electrician may recommend a different setup depending on your location and installation requirements.

    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 6kW 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.

  • Yes, we offer free delivery to most areas across Australia in line with our shipping policy. For rural or remote addresses, delivery conditions may vary, so contact our team before purchasing to confirm logistics and lead times for your area.

    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.

  • For a full breakdown of what actually matters when buying an outdoor sauna, from bench depth and insulation to where the electrical components are installed, read our outdoor sauna buying guide.
