NorthStar Indoor Sauna NSI-46

This 4’x6’ sauna is ideal for two or three people, including a top bench long enough to comfortably lie down.

Simply assemble, wire to a single 240V source (no additional 120V or other circuits needed), and you’re ready to enjoy your home sauna! As with all NorthStar saunas, the NSI-46 includes a SaunaLogic2 control with worldwide mobile app.
