The Finnleo Sisu freestanding, panel-built sauna brings a genuine Finnish sauna into an existing indoor space — a basement, spare room, gym, or wellness suite — without framing or custom carpentry. Precision-milled wall and ceiling panels interlock and bolt together, aligning to a tight, heat-locking seal that two adults can typically assemble in a day with basic hand tools.

• Your choice of Designer SL2 or Himalaya heater with SaunaLogic2 Wi-Fi control
