Sauna Buying Guide Australia
Choosing the right sauna should be exciting, not confusing. This guide walks you through the decisions that actually matter, sauna type, heater sizing, materials, installation and running costs, so you can invest once and enjoy it for years.
Sauna types explained
- Barrel saunas. Round, striking and quick to heat. The curved shape leaves less wasted air above your head, so they reach temperature fast and use energy efficiently. A natural fit for a backyard.
- Cabin saunas. The traditional square or rectangular room. More headroom and bench space, easier to seat a group, and flexible enough for indoors or out.
- Indoor saunas. Built into a bathroom, garage or dedicated room. They look seamless but need proper clearances, ventilation and electrical work.
- Infrared saunas. These warm your body with radiant panels at a lower air temperature. Gentler heat, but a different experience to a traditional hot, steamy sauna.
Barrel vs cabin: which suits you?
Choose a barrel if you want fast heat-up, lower running costs and a design feature for the yard. Choose a cabin if you want more room, more seating, and the freedom to place it indoors or out. Both take the same quality heaters, so the real decision is space, capacity and the look you are after.
Indoor vs outdoor
Outdoor saunas are usually the simpler retrofit; they need a level base, power and weatherproofing. Indoor saunas give you a premium, all-weather experience but require ventilation, moisture management and clearances to nearby surfaces. If you are going indoors, plan the airflow and electrical early.
Sauna heater sizing
Heater output is matched to the room, not guessed. As a rule of thumb, allow roughly 1 kW of heater power for every 1 to 1.5 cubic metres of cabin volume. Add capacity for glass doors, large windows or any uninsulated walls, since these lose heat faster. Undersize and you get long heat-up times; oversize and you waste energy.

Harvia vs Saunum heaters
Harvia is a proven Finnish brand with a wide, reliable range to suit almost any build. Saunum adds air-circulation technology that spreads heat and humidity more evenly through the room, for a gentler, more consistent feel from floor to ceiling. Both are excellent; Saunum is the pick if even, comfortable heat is your priority.
Materials that matter
Timber choice affects feel, smell and longevity. Thermally treated woods such as Thermo Aspen resist moisture and stay cooler to the touch, which is why we stock them for benches and cladding. Good materials are what separate a sauna that lasts a decade from one that does not.
Installation considerations
Plan for a level, load-bearing base, safe clearances and proper ventilation. Most electric heaters must be hardwired by a licensed electrician, and larger outputs may need a dedicated circuit or three-phase power. Scoping the electrical before delivery avoids surprises on install day.
Running costs
Running cost comes down to heater size, session length and your electricity tariff. As a guide, a session uses roughly the heater's rating in kilowatts multiplied by the hours you run it, so a 6 kW heater over a 45-minute session uses in the order of 4 to 5 kWh. Barrel saunas and well-insulated cabins keep this lower by heating faster and holding warmth.
