With the NSI-44, a true Finnish sauna experience is possible in only 16 sq. ft. of floor space. The NSI-44 comes equipped with the same features as other NorthStar saunas, but with the 120-volt stainless steel “Junior” heater (1.7 kW or 2.2 kW/120V/with cord/plug) instead of a 240-volt heater. Simply assemble, plug it into the closest dedicated outlet and you’re ready. As with all NorthStar saunas, the NSI-44 includes a SaunaLogic2 control with worldwide mobile app.
