Model S4B Outdoor Wood-Burning Hot Tub

The SaunaLife SOAK-Series Model S4 represents the very best in wood-burning hot tub quality, efficiency, and luxury.

Ready for your hot tub party

The Model S4B wood-fired hot tub arrives completely assembled and is easy to set up. Its ergonomically shaped fiberglass tub is a comfortable place for up to 6 people. The interior surface is easy to clean, and the exterior is crafted from thermally enhanced spruce for superior weather resistance and durability.

Engineered for efficiency and performance

Engineered and crafted in the Northers Europe, this super-efficient hot tub heats in 1/3 of the time as traditional wood-fired hot tubs. 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.

Start enjoying sooner

This 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.

Relax with friends and family the luxury of your Model S4 backyard wood-burning hot tub from SaunaLife.

Key Features

Highly Recommend This Company

The team at Soaknsweat was absolutely incredible. I honestly didn’t think customer service like this still existed. Kris and the crew actually answered the phone, patiently walked me through every question, and helped me make several key decisions for my sauna setup. They followed up quickly, were extremely professional, and truly earned my business and recommendation. Their YouTube content was also a huge help during the planning phase — and one of the main reasons I chose to order from them. Thanks, team!

Building Phase

I’m currently in the process of designing and building a sauna. After a lot of online research and frustration, I discovered Soak 'n Sweat — and it was a game changer. Their educational page covers every aspect of sauna design and answered nearly all my questions through detailed articles and videos. When I reached out via chat, Kris patiently addressed the rest of my questions without any pushy sales tactics. These folks really know their stuff, provide great products, and make the whole experience smooth and informative. Thank you!

All my questions answered

I had a question and reached out through the Soak 'n Sweat website chat — and within moments, a real person responded. Kris even went above and beyond by giving me a call, making it easy to get answers right away — and it was after business hours! Their knowledge, patience, and genuine willingness to help made the entire experience smooth and stress-free. I’m extremely impressed with their customer service and highly recommend Soak 'n Sweat to anyone looking for quality products and exceptional support.

Smooth transaction

This was my first time building a sauna, and I had tons of questions. Kris patiently guided me through everything — from venting and placement to the electrical setup. Thanks to the help, the heater installation went perfectly!

Great service and support

The response time was excellent, and every question we had was answered quickly. Their technical support was also outstanding. I’d definitely recommend Soaknsweat to anyone!
