This 23.5kW stove efficiently heats sauna rooms from 529 to 1,059 cubic feet. The dual-function design lets you heat the sauna from an adjacent room while enjoying fireplace ambiance.
What stones do I need and how many?
You'll need a minimum of 572 lbs of 10-15cm sauna stones (typically 13 boxes). We recommend purchasing one extra box since natural stones vary in size, giving you options for the best fit.
