Overview
The Nordhaus 4-6 Person Traditional Sauna is built from premium Canadian hemlock and powered by a 6kW electric heater, delivering the high, dry heat associated with traditional Finnish-style sauna bathing.
Dual-tier benches seat up to six people, with sauna stones included so you can pour water over them to generate steam (löyly) and adjust humidity during a session.
Canadian hemlock is widely used in sauna construction for its low resin content, resistance to warping under sustained heat, and light, tight grain.
Suited to households or shared spaces wanting a full-size, authentic traditional sauna with room for family or guests, supporting relaxation, circulation, and post-workout recovery.

FAQ
Everything you need to know before choosing your sauna. Still unsure? Call 0401 696 261 or email sales@nordhaus.com.au.
It reaches up to 90°C. A 6kW Harvia electric heater warms 20kg of sauna stones, which gives the high, dry heat of a traditional Finnish-style sauna. Pour water over the stones to add a burst of steam and lift the humidity.
The heater runs for up to 4 hours at a time and has a 1 to 8 hour preheat timer, so you can set it to be hot when you get home.
A traditional sauna heats the air. An electric heater warms sauna stones, the room climbs to as much as 90°C, and you can pour water on the stones for steam.
An infrared sauna heats your body directly with infrared panels, so the air stays cooler. Nordhaus full spectrum infrared saunas run between 30 and 75°C.
Choose traditional if you want high heat, steam and the classic sauna ritual. Choose infrared if you prefer a gentler heat at a lower temperature. Our sauna buying guide compares the two in detail.
The 6kW Harvia heater needs a dedicated 35 amp circuit, installed by a licensed electrician. The sauna is supplied ready for electrical installation, and your electrician completes the final connection, either a wall socket or hardwiring, to suit your home.
The cost of the electrical work depends on your switchboard and how far the cable has to run, so it is worth getting a quote from a local electrician before you order.
Yes. This is a traditional sauna, so pouring water on the hot stones is part of the experience. It comes with 20kg of Harvia sauna stones and a Finnish style bucket and ladle.
No drainage is needed. A drip tray is supplied with the heater, and the removable slatted timber floor sits over your existing floor.
The sauna measures 180cm wide x 150cm deep x 200cm high and seats four to six adults.
Allow around 200mm of extra clearance during assembly so the sauna can be positioned safely, and keep the intake and exhaust vents clear so air can circulate.
It is designed for indoor use, and it can also go under a patio or veranda or inside a garage where it is fully protected from the weather.
It should not sit out in the open. Water damage to an indoor model used outdoors is not covered by warranty. If you want a sauna for an exposed backyard, see our outdoor traditional saunas, which are built for it.
Yes. Our indoor saunas can be built into a wall or custom cavity for a seamless finish. Allow about 200mm of additional clearance so the sauna can be assembled and positioned, and make sure the cavity is ventilated with all sauna vents left unobstructed.
No. The sauna includes removable slatted timber flooring that sits over any existing floor, which makes cleaning easy. No drainage is required, as the heater has its own drip tray.
It arrives flat-packed in multiple boxes and is an easy DIY job for two people, taking approximately 45 minutes. The heater must then be connected by a licensed electrician.

The cabin is built from Canadian Hemlock, a timber widely used in saunas because it is low in resin and stays stable under sustained heat. The front is 8mm tempered safety glass, lighting is a white LED strip, and ventilation is roof mounted with airflow holes in the glass panel.
Regular traditional sauna use is commonly associated with relaxation, stress relief, improved circulation and muscle recovery. Many owners use it as a daily ritual to switch off, and pair it with a cold plunge for contrast therapy at home.
Care is simple. Wipe the benches down after use and leave the door open so the cabin can air dry. The removable floor lifts out when you want to clean underneath.
For home use, the cabin and electrical components are covered for 5 years, the Harvia heater for 2 years, and the heater elements and accessories for 1 year. Commercial use is covered for 1 year. Full details are on our warranty page.
