Before you buy: what to know
Based on the manufacturer's specs, manuals and our research.
- The Harvia 50 is 40 kW, for large rooms from 706 to 1,766 cu ft. For a typical home sauna under 700 cu ft, a smaller stove will be a better fit.
- It holds 264 lb of stones, included, for long-lasting steam through extended or back-to-back sessions in a commercial or large home sauna.
- Clearances to walls, ceiling and benches come from the installation manual, and a wood stove also needs a proper chimney run. Check local code and your insurer before you build around it.
- It usually ships within 1 to 3 business days and arrives in about 5 to 10 business days, so it can be on site before your build is finished.
- Returns are accepted within 30 days with a 25% restocking fee on unused, unopened items. Work out your room volume first, so the output you order is the right one.
