Good to know: The $5,990 price doesn't include a heater or its controls. Sauna Kit Co offers four electric heaters, and the cheapest pairing, a 6 kW Harvia KIP with built-in controls, brings the total to $7,061. SaunaLife's current warranty PDF gives two years, though its product pages still say lifetime.

What to know before you buy
Thermowood, Spruce, electric, 240V hardwired. These decide whether it suits your space and your electrical panel.
- ThermowoodThermowood is heat-treated without chemicals, so it holds its shape and resists rot. Outdoors, it stands up to rain and snow through freeze-thaw cycles.
- Nordic SpruceNordic spruce is the traditional Finnish sauna softwood. It's tight-grained and light, and the price is fair.
- ElectricAn electric heater holds a steady temperature on its thermostat and needs no chimney. Many models add app or timer control.

Where we’ve written about it
Outdoor Saunas
Barrel vs. cube: which outdoor sauna shape heats better?
The barrel's curve came from cooperage, and it encloses less air than a box with the same benches. The cube answers with headroom and two bench tiers, and its flat walls take bigger glass. Pick by how many people you heat for and how long you'll wait.
