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. | 10 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. | 75" W x 64" D x 84" H |
| Power requirements | Infrared: 240V, 15A, NEMA 6-15P; Harvia KIP45B traditional heater: 240V, 20A ("Electrician Required") |
| Wood | Clear "A" grade Canadian Western Red Cedar (interior), Thermal Plus Canadian Aspen (exterior) |
| Placement | Indoor |
