Outdoor Sauna What better way to spend quality time with family and friends than in the backyard? Finnleo's Metro outdoor saunas tie in perfectly with outdoor entertaining -- pool side, spa-side, near the patio, or lakeside. Since three of the four Metro models include spacious changing rooms, these wonderful backyard amenities can easily double as a pool-house. With a Metro sauna near the pool, the swimming season can be extended providing the ultimate experience of "sauna with a cool water plunge."The Metro is designed for easy assembly. The walls and roof are constructed of 4 1/4" insulated panels. Each panel is finished on both sides. The interior comes standard with tongue-and-groove Nordic White Spruce -- in the sauna and the changing room. The exterior comes standard with Nordic White Spruce T&G (to be painted or stained) or optional maintenance free siding.
