Family bathing with the fire kept outside \u00b7 Made-to-order outdoor hot tub<\/p>\n

Wood Fired Hot Tub with External Stove \u2013 TimberIN Nordic\u2122 External Comfort: an external stove that preserves the full interior<\/h2>\n

\n<\/header>\n

\n

More room in the water and a clearly separated heating zone<\/h2>\n

With no stove occupying the shell, the round interior remains open for communal seating and is easier to understand at a glance. The external heater can be approached for loading and ash removal without disturbing bathers, which is valuable for family and hospitality use. Water circulates between tub and stove through an approved lower and upper connection, so pipe geometry is central to performance. The hybrid option adds electric support for a different operating routine, while the selected cladding timber determines the exterior tone and maintenance character.<\/p>\n<\/section>\n

\n

The two external-stove sizes in exact figures<\/h2>\n

External Comfort is designed around clear bathing space: the wood burner stands beside the tub rather than taking a seat or becoming part of the shell. The 1,800 mm version is a 4\u20136-person, 1,400-litre model; the 2,000 mm version increases that to 6\u20138 people and about 1,550 litres. Both are approximately 150 kg before separate heater, stairs and equipment packages, so the final footprint is larger than the circular shell alone.<\/p>\n

External-only simplicity or external wood plus electric support<\/h2>\n

The wood-only route is the cleanest operational concept: fire for each session, no high-power holding circuit and all seats available. Hybrid heat is better where the tub will be used frequently, where frost support is required or where a schedule matters, but it adds wiring, controls and another enclosure. The 1,800 mm shell is the efficient family choice; the 2,000 mm shell earns its extra volume only when six to eight people are normal. Timber selection should follow the desired maintenance and finish, not be confused with the smooth liner\u2019s water-side care.<\/p>\n

Use the external layout to keep service access generous<\/h2>\n

An insulated leather lid works across the timber choices and reduces heat loss; the wooden round-edge\/lid route is limited to spruce and Thermowood. Filtration belongs near the top of the list for retained water. Hydromassage adds stronger jets and more plumbing than air massage. Keep every pump, filter and heater connection visible or behind removable panels. A chimney guard is sensible, but the stove still needs a non-combustible zone and a firebox route that does not cross the main bathing path.<\/p>\n

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

Already included:<\/strong> (1) \u201cA\u201d type luxury wooden stairs; (2) Wooden paddle<\/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

\n
\n

Type of lid<\/h3>\n
    \n
  • With wooden round edge and lid (applicable only for spruce and thermowood type)<\/li>\n
  • Insulated leather lid (recommended)<\/li>\n<\/ul>\n

    Advantages:<\/strong> A fitted cover reduces debris and heat loss; an insulated leather cover is normally lighter to handle and more thermally effective than a plain timber lid.<\/p>\n<\/section>\n

    \n

    Insulation<\/h3>\n
      \n
    • Wall insulation<\/li>\n
    • Bottom insulation<\/li>\n<\/ul>\n

      Advantages:<\/strong> Wall and bottom insulation reduce heat loss from the water vessel and are particularly useful for frequent use, exposed sites and electric temperature holding.<\/p>\n<\/section>\n

      \n

      SPA<\/h3>\n
        \n
      • Air bubble massage system<\/li>\n
      • Hydro massage system<\/li>\n
      • Sand filtration system with big wooden cover box<\/li>\n
      • 2 LED<\/li>\n
      • 4 LED (Recommended for 180 – 220 cm models)<\/li>\n<\/ul>\n

        Advantages:<\/strong> Air massage gives a gentle whole-tub effect, hydromassage provides firmer targeted jets, filtration supports retained-water use and LEDs improve evening visibility and atmosphere.<\/p>\n<\/section>\n

        \n

        Smart SPA equipment add-ons (WiFi signal required)<\/h3>\n
          \n
        • Smart app \u2013 voice controlled system kit for air massage<\/li>\n
        • Smart app \u2013 voice controlled system kit for water massage system<\/li>\n
        • Smart app \u2013 voice controlled system kit for sand filter<\/li>\n
        • Smart app \u2013 voice controlled system kit for electric heater (enables scheduled control)<\/li>\n<\/ul>\n

          Advantages:<\/strong> App control can schedule electric support and make filtration, air massage or hydromassage easier to prepare before a planned soak, with separate control applied only to the systems selected.<\/p>\n<\/section>\n

          \n

          Inside color<\/h3>\n
            \n
          • White (RAL 9001)<\/li>\n
          • Blue (RAL 5012)<\/li>\n
          • Gray (RAL 7015)<\/li>\n
          • Blue Pearl (RAL 7700)<\/li>\n
          • Gray Pearl (RAL 7730)<\/li>\n
          • Granite (RAL 9001)<\/li>\n<\/ul>\n

            Advantages:<\/strong> Liner colour lets the visible bathing shell coordinate with the garden and can make the water appear lighter, deeper or more neutral without changing the tub geometry.<\/p>\n<\/section>\n

            \n

            Metal parts<\/h3>\n
              \n
            • Metal fence on the chimney (heat protection)<\/li>\n
            • Ash shovel and rake<\/li>\n<\/ul>\n

              Advantages:<\/strong> A chimney guard reduces accidental contact risk, a heater lid controls access around the firebox, and dedicated metal tools make ash handling and routine stove care more orderly.<\/p>\n<\/section>\n

              \n

              Water release type<\/h3>\n
                \n
              • Bottom water drain with a stopper (included)<\/li>\n
              • External water tap<\/li>\n
              • External water tap + Quick adapter for garden hose set (12.5mm & 15mm)<\/li>\n<\/ul>\n

                Advantages:<\/strong> An external tap gives better control over discharge, while the quick hose adaptor helps route water away from foundations, neighbours and soft landscaping.<\/p>\n<\/section><\/div>\n<\/section>\n

                \n

                The external pipe run is part of heating performance<\/h2>\n

                The technical sheet gives no guaranteed time. TimberIN\u2019s manual uses a broad 2\u20133 hours in warmer weather and 4\u20136 hours in cold weather, with roughly 8\u00b0C per hour for a 2,000-litre example under stated use. External Comfort holds 1,400 or 1,550 litres, but long or poorly insulated connections, wind and a missing cover increase loss. Keep pipe runs as designed, use dry fuel, mix the water and reduce firing before the target temperature is reached.<\/p>\n<\/section>\n

                \n

                Give the heater room to breathe and water room to circulate<\/h2>\n

                Allow a firm base beneath both tub and stove, a short supported pipe route and safe access to the firebox. Follow the final drawing for connection heights and do not reduce pipe diameter or add restrictive valves casually. Keep the chimney clear of eaves, covers and planting. If hybrid support is chosen, arrange compliant electrical work to the supplied equipment data. Choose 180 or 200 cm based on regular occupancy and water volume, then confirm delivery access, drainage and a winter routine before the surrounding terrace is finished.<\/p>\n<\/section>\n
