ThermaSauna M is made for up to 4 persons. There are 2 full size bunks inside, 1 glass door and 1 window. Due to powerful Harvia M3 wood fired heater sauna warms up in an hour, so you can enjoy bathing more often as it can be organized spontaneously in an hour.


Sauna does not require heavy fundament. It can be placed almost anywhere temporary, but for a permanent installation we recommend to put it on terrace, paving, stone chips or at least few bricks under corners. 


  • Sauna walls and ceiling are made of raw and solid 42 mm spruce wood, held together with tongue & groove joint and long screws. Construction is strong and very stable, which makes it safe to lift the whole sauna (i.e. for transportation, to change location in your garden, to sell it in future etc). We deliver our saunas fully assembled, but our team can come and build it at your garden as well. Contact us if you want to order the sauna with delivery.
  • Sauna floor is made from 27 mm impregnated terrace boards, mounted with little gaps for ventilation. An adjustable ventilation grid is installed in the highest point of the wall.
  • Roof is covered with coated steel tin. Steel roofs are long lasting and carefree. Available colours: Grey RAL 7024 matt, Brown RAL 8019 matt, and Red RAL 3009. Standard flat (single pitched) roof can be changed to traditional (double pitched) roof for €300.
  • Standard sauna is made with toughened and tinted glass door for entrance and 1 window. Entrance door made of 6 mm tempered and tinted glass. Window from 6 mm tempered and tinted glass. 
  • It is possible to change the entrance door to traditional wooden door €150 or wooden door with windows €170. Panoramic sliding aluminium doors with aluminum framed windows are made from 5 mm tempered glass €300.
  • Additional windows can be added on any wall of the sauna. Additional window 30x94 cm €80, 60x94 cm €80, 60x148 cm €130, 120x148 cm €200, 60x175 cm €150, 120x175 €200.
