Homecraft Revive Slim Electric Sauna Heater | 8-Inch Deep, 4, 5 and 6 kW

That is the difference between a bench you can actually sit on and a room you gave up on. Three outputs from 4 to 6 kW for rooms of 100 to 325 cubic feet, stainless throughout, built in Surrey, British Columbia, CSA and UL certified.
