Specifications
Manufacturer list pricewhat this means: Manufacturer list priceThe verified price above is $2,990.00 below what the manufacturer lists. | $10,980.00 |
|---|---|
| Capacity | 4 persons |
| Heater power | 6 kW |
Warrantywhat this means: WarrantyThe warranty term the manufacturer publishes, in years. Some makers instead warrant the sauna structure for the life of the original owner, which this column shows as "Limited lifetime"; that is a different promise from a fixed number of years and covers the shell rather than the heater, so the two are not ranked against each other. | 2 yr |
Exterior dimensionswhat this means: Exterior dimensionsThree figures as the manufacturer publishes them. The source does not name which is width, depth or height, so this site does not label them either. | 86 x 65 x 90 in |
| Power requirements | 240V / 30AThe maker publishes a 30 amp circuit. Sized from the 6 kW heater by the 125 percent continuous load rule, the minimum is 35 amps on 8 AWG copper. NEC 422 gives the rating marked on a listed appliance authority over that calculation, so both figures can be right; your electrician decides which applies to your run. Check it on the calculator. |
| Wood | Thermally treated pine (walls), thermo-alder (benches) |
| Placement | Outdoor |
Practical numbers
- Power circuit
- 240V / 30A; needs a 240 V circuit; an electrician typically installs a dedicated line
- Cost per one-hour session
- About $1.10 at the national average residential rate (June 2026); heater power times session length times your electricity rate
Measured against other models around 4 person capacity, this model sits mid-range on capacity, heater power, and warranty: nothing here is a high or a low worth calling out.
