No electrical connection is required. At the heart of the Model S4 is its ingenious self-cleaning corrugated stove with a secondary chamber that transfers heat from the smoke – reducing wood consumption up to 50% compared with other hot tubs. Brilliantly, the air between the fiberglass lining and the wood exterior is super-heated to accelerate the heating process. The stove is cleverly engineered to draw cooler water through a lower channel and redistribute it though an upper channel to equalize the temperature.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003eStart enjoying sooner \u003cbr\u003e\u003cbr\u003eThis incredibly efficient wood stove will heat 304 gallons of water from 40°F (5°C) to 95°F (35°C) in 1.5 to 2 hours – the fastest-heating wood burning hot tub available.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003eRelax with friends and family the luxury of your Model S4 backyard wood-burning hot tub from SaunaLife.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-sheets-root=\"1\"\u003eFeatures\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003eModel S4 Outdoor Wood-Burning Hot Tub \u003cbr\u003e• Thermo-Spruce materials (lasts up to 2X longer than Cedar) \u003cbr\u003e• Luxury outdoor wood-burning hot tub \u003cbr\u003e• Designed for outdoor ergonomic hot tub bathing experiences \u003cbr\u003e• Arrives fully assembled and no electricity required (eco-friendly) \u003cbr\u003e• Spacious interior holds over 304 gallons of pure water bathing pleasure \u003cbr\u003e• Thick dark grey contoured fiberglass lining provides enhanced bather comfort \u003cbr\u003e• Stainless steel wood-burning heater utilizes dual heat compartments for unmatched efficiency \u003cbr\u003e• Rapid response heat-up time prepares water to ideal temperatures in under 2-hours \u003cbr\u003e• Wood-burning heater constructed of 304 stainless steel \u003cbr\u003e• Polished stainless steel chimney with protection \u003cbr\u003e• Durable Thermo-Spruce tub surround (1.65” thick), painted black \u003cbr\u003e• Superior thermal resistance (R-value) to retain heat \u003cbr\u003e• Matching Thermo-Spruce wood steps for easy access \u003cbr\u003e• Extra thick steel reinforced foam cover, folds for ease of removal and storage \u003cbr\u003e• Dark grey marine grade vinyl cover exterior \u003cbr\u003e• Integrated hot tub drainage tap \u003cbr\u003e• Up to 6 bathers \u003cbr\u003e• Exterior dimensions – 79\" diameter and 37” high \u003cbr\u003e• Interior dimensions – 71\" diameter and 33” deep \u003cbr\u003e• Designed by SaunaLife and handcrafted in Northern Europe \u003cbr\u003eThermo-Spruce Material Advantages \u003cbr\u003e• Lasts up to 2X longer than Cedar \u003cbr\u003e• Superior thermal resistance (R-value) \u003cbr\u003e• Eco-friendly \u003cbr\u003e• Ideal for water use (stable)\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-sheets-root=\"1\"\u003ePackage Contents\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003eFully assembled hot tub, Steps, Insulated cover, Drainage with tap, Polished stainless steel chimney, Chimney cap \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"SaunaLife","offers":[{"title":"Default Title","offer_id":50338972205342,"sku":"SL-MODELS4B","price":6990.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/8294\/1982\/files\/Screenshot2025-11-13205950.png?v=1763085604","url":"https:\/\/saunaburns.com\/products\/saunalife-model-s4-wood-fired-hot-tub","provider":"SaunaBurns","version":"1.0","type":"link"}
