ThermaSauna 6XL is made for up to 8 persons. There is a resting area and sauna area separated by the wall and glass door. There are 2 full size bunks inside the sauna, 1 entrance glass door and 2 windows. 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 and resting area 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.
  • Floor is made from 27 mm 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 (colour Grey RAL 7024 matt) . Steel roofs are long lasting and carefree. 
  • Standard sauna is made with toughened and tinted glass door for entrance (to sauna and resting area) and 2 windows (1 in sauna and 1 in resting area). Entrance door made of 6 mm tempered and tinted glass. Windows from 6mm tempered and tinted glass. 
  • It is possible to change the entrance door to traditional wooden door for additional €150 or wooden door with window +€200. 
  • It is also possible to change standard sauna door to panoramic sliding (2 parts or 3 parts) aluminium doors with alu framed windows made from 5 mm tempered glass for €350 - €450.
  • Additional windows can be added. 30x94 cm +€50, 60x94 cm +€100, 60x148 cm +€100, 120x148 cm +€200, 60x175 cm +€200, 120x175 +€200.
  • 2 aspen wood benches 187 x 58 cm. Up to 2 persons can lay down on benches, or up to 8 persons can sit. Benches are placed in different height for better comfort adjusting to hot temperature when in use (heat goes upwards).
  • Sauna is heated with Harvia M3 13 kW wood fired heater. Electric Harvia Trendi KIP 90 9 kW heater is optional (cheaper by €150). The heater is placed on a special metal protective tray (10 cm height). The walls near the stove are protected by Cembrit board. The chimney output port is insulated with a special heat-resistant wool, Cembrit board inside and stainless steel sheet outside.
