Finnleo Northstar Outdoor 5x7

This is the largest model in Finnleo's NorthStar outdoor line: a ready-made freestanding sauna building measuring 84" W x 60" D x 84" H (100" W x 87-7/8" H x 84" D at its largest dimensions with the included metal roof kit) and weighing roughly 1,470 lbs. It is built in Nordic White Spruce inside and out with clear Abachi or Aspen benches and backrests, seats five on an L-shaped bench, and adds a window that the smaller NorthStar models lack. Heat comes from a Designer-SL2 6.0 kW electric heater on a 240V, 30-amp single-phase circuit, with an integral waterproof vinyl floor, in-backrest color-therapy lighting, and a RENTO Pisara bucket and ladle in the box; a Bluetooth sound system is an optional add-on.

The commitment is what you would expect of a backyard building. Beyond the roughly $12,500 approximate dealer price, you need a prepared level site, delivery of a very heavy structure, and an electrician to run the 240V/30A circuit — installation costs Finnleo's page does not quantify. The page also leaves maximum temperature and warranty terms unstated, both dealer questions. For buyers who want an authentic outdoor Finnish sauna with US manufacturing behind it rather than a kit from an import brand, the NorthStar's spec sheet — 6 kW heater, five seats, included roof — is among the more complete in the dealer channel.
