Engineered for Efficiency
At the heart of every wood fired hot tub in the Soak Series is a revolutionary heating system that outperforms traditional designs by a significant margin. The patented 304 stainless steel stove is durable and exceptionally intelligent in how it transfers heat to your water.
The secret lies in the corrugated stove design and secondary heat chamber. This innovative hot tub wood burning system maximizes surface contact with the water, allowing heat to transfer three times faster than conventional wood-fired heaters. How you’ll benefit from this. Your tub reaches the perfect temperature in approximately two hours, compared to six or more hours with older designs. That's the difference between deciding to soak and actually soaking the same evening.
But speed isn't the only advantage. This wood burning hot tub stove is remarkably efficient with fuel consumption, using up to 50% less wood than traditional models. The secondary combustion chamber captures and burns gases that would otherwise escape, extracting maximum heat from every log you add. This saves you money on firewood and also makes your sessions more environmentally responsible.
The self-cleaning design of the hot tub wood burning stove means less maintenance and more enjoyment. The corrugated structure prevents ash buildup, while the high-grade stainless steel construction resists corrosion even with constant water contact. This is what makes the Soak Series the best wood fired hot tub for those who want performance without constant upkeep.
Since it's a completely wood fired hot tub self contained system, you'll not have to worry about electrical failures, circuit breakers, or power outages interrupting your relaxation. The independence this provides is liberating — your wood fired hot tub works whenever you want it to, regardless of what's happening with the power grid. For remote properties or those seeking true self-sufficiency, this wood fired hot tub self contained design is simply unmatched.
Luxury Design & Durability
Beauty and longevity go hand in hand with the Soak Series, where premium materials meet thoughtful design. The exterior showcases stunning Thermo-Spruce hot tub surrounds that are as durable as they are attractive.
Thermo-Spruce undergoes a specialized thermal treatment process that fundamentally changes the wood's structure. These Thermo-Spruce hot tub panels, measuring a substantial 1.65 inches thick, resist rot and warping up to twice as long as traditional cedar or pine. The thermal modification process removes moisture-attracting compounds, making the wood naturally resistant to decay, insects, and the harsh elements your outdoor hot tub will face year after year.
The Thermo-Spruce hot tub exterior maintains a deep, consistent color that gradually forms a stunning patina, aging smoothly without the cracking or splintering typical of untreated wood. This is about creating a luxury hot tub that maintains its beauty and structural integrity through countless seasons of use.
Inside, the contoured fiberglass hot tub liner provides exceptional comfort and hygiene. Unlike wooden interiors that can harbor bacteria or require constant treatment, the smooth fiberglass surface is naturally non-porous and easy to clean. The ergonomic molded seats provide proper back support and comfortable positioning for every guest.
This fiberglass hot tub interior comfortably accommodates up to a 6 person hot tub capacity, holding over 304 gallons of water. The seating layout ensures everyone has their own space without feeling cramped, making it perfect for family gatherings or entertaining friends. The circular hot tub design goes beyond tradition by enhancing natural circulation and encouraging a more inviting, shared experience.
The combination of the weather-resistant Thermo-Spruce hot tub exterior and the durable fiberglass hot tub interior creates a luxury hot tub that's truly built to last, requiring minimal maintenance while delivering maximum enjoyment.
Model S4 Spotlight: The SaunaLife Soak S4B and S4N
The Soak Series offers two distinct models to match your aesthetic preferences: the SaunaLife SOAK S4B and SaunaLife SOAK S4N.
The SaunaLife SOAK S4B wood-fired hot tub model features a striking black fiberglass interior that creates a modern, sophisticated look. The dark liner beautifully contrasts with the natural wood exterior and gives your water a deeper, more mysterious appearance.
Prefer a lighter, more natural aesthetic? The SaunaLife Soak S4N wood-fired hot tub model showcases a natural-toned fiberglass interior that complements the Thermo-Spruce exterior for a cohesive, organic appearance. The lighter color creates a bright, inviting feel that many find more visually spacious.
Both the SaunaLife Soak S4B and SaunaLife Soak S4N models deliver identical performance, the same 6 person hot tub capacity, and the revolutionary wood burning hot tub efficiency that defines the series. The choice simply comes down to your personal style preference.
Every SaunaLife S4 model arrives fully assembled and ready for immediate setup.
