The classic barrel, sized from two to five metres \u00b7 Made-to-order outdoor sauna<\/p>\n

TimberIN Nordic Barrel\u2122 Classic: a proven curved form that can grow with the room plan<\/h2>\n

\n<\/header>\n

\n

Curved walls make efficient use of heat and create the familiar barrel feel<\/h2>\n

The circular section reduces unused high corners and gives the interior an enveloping character, with opposing benches that support conversation. At the compact end of the range, nearly all available length can be dedicated to the hot room. Longer variants create room for a more generous bench arrangement or additional functional zones, but they also increase air volume and external scale. Spruce has a pale traditional expression, while Thermowood offers a darker heat-treated appearance; both remain outdoor timber surfaces that need ventilation, drainage and maintenance appropriate to the supplied finish.<\/p>\n<\/section>\n

\n

Barrel length, occupancy, weight and heater match<\/h2>\n

Nordic Barrel Classic is a mature model family with a useful technical progression. At 2 metres it is a focused 2\u20134-person room of about 800 kg; at 3 metres it is 4\u20136 and about 1,100 kg; at 4 metres it becomes 6\u20138 and about 1,400 kg; at 5 metres it reaches 8\u201310 and about 1,700 kg. Intermediate live lengths refine the plan, but a dressing room or porch is taken from the stated total length and therefore reduces heated bench space.<\/p>\n

Do not spend heated length twice<\/h2>\n

Choose length around the sauna room first. A 3-metre building with a 1-metre dressing room leaves roughly a 2-metre hot room; a 4-metre unit can combine 3 metres of sauna with a 1-metre changing space; a porch has the same subtractive effect. M3 is the normal wood choice for 2\u20134 metre sauna rooms, while 20-series heaters serve larger rooms. SL models load from outside. A 9 kW Cilindro fits 2\u20133 metre rooms; the 11 kW route serves larger volume. Spruce or Thermowood should be decided after layout and heater.<\/p>\n

Insulation, rooms and windows change performance as well as appearance<\/h2>\n

Complete insulation is most valuable for frequent winter use and large glazed builds, but is technically best in a factory-assembled sauna. A dressing room improves comfort and protects clothes from weather; it reduces hot-room length. A porch gives sheltered seating with the same trade-off. Panoramic glass opens the view and increases heat loss; two small windows retain more privacy. A water tank adds practical warm water to wood-fired use, while LEDs and entrance lamps need a heat-rated electrical installation. Flat pack solves access but transfers precision assembly to the site.<\/p>\n

What the current configurator identifies as included<\/h3>\n

Already included:<\/strong> (1) Benches as in pictures; (2) Entrance door with a small window; (3) Ventilation<\/p>\n

Included equipment is valuable because it establishes a usable baseline. Displayed builds may contain additional systems, so the accepted quotation should repeat every included item.<\/p>\n<\/div>\n

Wood burning Harvia heaters<\/h3>\n
    \n
  • Recommended for 2 – 4 meter sauna room: Harvia M3 + chimney (already included)<\/li>\n
  • Recommended for 2 – 4 meter sauna room: Harvia M3 SL + chimney (logs loaded from outside instead of inside)<\/li>\n
  • Recommended for 4 – 5 meter sauna room: Harvia 20 PRO + chimney<\/li>\n
  • Recommended for 4 – 5 meter sauna room: Harvia 20 SL + chimney (logs loaded from outside instead of inside)<\/li>\n
  • Need different wood burning stove? Contact us!<\/li>\n<\/ul>\n

    Advantages:<\/strong> Harvia wood-burning heaters provide the traditional fire-and-stone sauna experience. M3 suits the smaller listed rooms, while 20 PRO serves the larger range; SL versions move log loading outside, keeping bark and ash out of the hot room.<\/p>\n<\/section>\n

    \n

    Electric Harvia heaters<\/h3>\n
      \n
    • Recommended for 2 – 3 meter sauna room: Cilindro 9 kW (PC90) with an integrated control unit (already included)<\/li>\n
    • Recommended for 4 meter sauna room: Cilindro 11 kW (PC110XE) including a separate control unit<\/li>\n
    • Need different electric stove? Contact us!<\/li>\n<\/ul>\n

      Advantages:<\/strong> A Cilindro electric heater offers repeatable thermostat control, no indoor fuel storage and a straightforward start-up routine. The listed 9 or 11 kW choices allow output to follow the actual heated sauna-room volume.<\/p>\n<\/section>\n

      \n

      Thermal insulation<\/h3>\n
        \n
      • For sauna 2 \u2013 3 m. of length: complete insulation + decorative wood panelling (due to technical reasons, recommended for factory assembled saunas)<\/li>\n
      • For sauna 4 \u2013 5 m. of length: complete insulation + decorative wood panelling (due to technical reasons, recommended for factory assembled saunas)<\/li>\n<\/ul>\n

        Advantages:<\/strong> Insulating the sauna envelope reduces heat loss, improves winter recovery and makes temperature more stable between the heater and benches; decorative internal panelling also protects the insulated build-up.<\/p>\n<\/section>\n

        \n

        Configuration<\/h3>\n
          \n
        • Dressing room 1 m (included in total sauna`s length)<\/li>\n
        • Dressing room 1.5 m (included in total sauna`s length)<\/li>\n
        • Glass door between sauna and dressing rooms<\/li>\n
        • Canopy – terrace with side benches 1 m (included in total sauna`s length)<\/li>\n
        • Custom configuration needed? Please send us your sketch<\/li>\n<\/ul>\n

          Advantages:<\/strong> A dressing room creates a dry transition area, a canopy provides shelter outside, and side-entry or U-bench layouts can make the sauna work with a particular view and garden approach.<\/p>\n<\/section>\n

          \n

          Accessories<\/h3>\n
            \n
          • Stainless steel water tank for wood burning heaters (steam effect)<\/li>\n
          • Electric installation. Few LED lights under the benches<\/li>\n
          • 2 Harvia lamps above the entrance door (both sides)<\/li>\n
          • Wooden fence in front of heater<\/li>\n<\/ul>\n

            Advantages:<\/strong> Heat-rated LED or Harvia lighting improves safe use after dark, a correctly matched water tank can provide warm water with a wood heater, and a timber heater fence creates a clear physical boundary around hot surfaces.<\/p>\n<\/section>\n

            \n

            Window type<\/h3>\n
              \n
            • 2 small windows<\/li>\n
            • Panoramic window (glass area 50%)<\/li>\n
            • Panoramic window (glass area 100%)<\/li>\n<\/ul>\n

              Advantages:<\/strong> More glazing opens the hot room to the landscape, brings daylight to the benches and makes a compact sauna feel less enclosed.<\/p>\n<\/section>\n

              \n

              Roof colour<\/h3>\n
                \n
              • Black tiles<\/li>\n
              • Brown tiles<\/li>\n
              • Green tiles<\/li>\n<\/ul>\n

                Advantages:<\/strong> Roof colour lets the sauna sit deliberately within the garden scheme without changing the room plan or bathing experience.<\/p>\n<\/section><\/div>\n<\/section>\n

                \n

                Warm-up changes with every room subdivision<\/h2>\n

                The sheet correctly avoids one number of minutes for a 2\u20135 metre family. Heater sizing uses the heated cubic volume after subtracting dressing room or porch, then adjusts for glass and insulation. A large heater in a short room is not a shortcut; an undersized heater in a glazed 5-metre build is equally poor. Ask the final drawing to state hot-room dimensions and heater match. Commission with the ventilation open as designed and measure warm-up under realistic winter conditions.<\/p>\n<\/section>\n

                \n

                Choose length by drawing the people and functions first<\/h2>\n

                Decide how many adults will sit or recline at the same time and whether anyone needs a changing or cooling threshold inside the shell. Ask for the internal layout of the chosen length rather than assuming every extra metre becomes usable bench. Heater output must account for room volume, glazing and local exposure. Prepare continuous level support, confirm crane or delivery access and orient the door away from awkward wind and public sightlines. Keep the lower shell clear of standing water and preserve access for exterior timber care.<\/p>\n<\/section>\n
