| Precision Therapy 2 Person Ceramic Outdoor Far Infrared Sauna - ETL Approved Precision Therapy 2 Person Ceramic Outdoor Far Infrared Sauna - ETL Approved features high quality lumber and double wall construction. Using separate tongue and groove panels on the inside and outside provide an insulation gap between the 2 walls, ensuring proper heat retention in your sauna. The wood used in this Precision Therapy 2 Person Ceramic Outdoor Far Infrared Sauna is not the normal 4" wide planks that are found in most saunas. Our saunas use wood that is approx. 2" in width. This helps create a tighter more rigid sauna room and retains heat much better. |
