SaunaLife S1N: a fully assembled immersion tub in natural thermo wood
The SaunaLife S1N is an outdoor cold and hot immersion tub for one person. A natural thermo wood surround frames a dark gray fiberglass shell, and the tub comes fully assembled. Thermo wood is wood treated with heat. The basin follows the shape of your body, giving you a contoured place to sit for a cold dip or warm soak. At 40 inches across and 41.3 inches tall, the tub gives you a clear starting point for choosing a spot outside. It holds 124 gallons, and matching wood steps come with it to help you get in and out.
The tub includes a drain and connections for a chiller. You can add an insulated cover on this page. Delivery comes by freight truck, with a curbside appointment arranged for its arrival. The tub travels on a wooden pallet, and the driver lowers it to the ground. Prefer a black exterior? See the SaunaLife S1B immersion tub. The SaunaLife S1N ships from Norse Steam by flat rate freight with No Sales Tax (except WY) and our 100% price match guarantee.
SaunaLife Outdoor Saunas
These rooms let you stay connected to your natural surroundings during each session. Crafted from high-grade, thermally modified wood, each space is built to withstand changing weather year after year.
The features within each room work together to create a comfortable bathing environment. Select from a variety of sizes and styles in the SaunaLife Outdoor Sauna Collection.
Barrel Outdoor Saunas
Create a personal backyard sauna sanctuary with SaunaLife outdoor sauna barrels. These spaces deliver a relaxing experience just steps from your home.
SaunaLife barrel saunas are ergonomically engineered for comfort, with contoured seating and wood slanted backrests. Available in a variety of sizes and configurations to suit your needs.
Cube-Series Saunas
Premium materials are evident throughout the Cube-Series lineup. The exterior is built from durable, full-length Thermo-Spruce staves that have been organically thermally enhanced, making them stronger, more dimensionally stable, and naturally resistant to decay and pests without chemical treatment. A complete shingle kit with drip rails ensures effective water management. The bronze-tinted 8mm tempered glass front door is both a design statement and a safety feature.
The CL3G specifically uses 42mm Thermo-Spruce staves for the side walls and 28mm panels for the front and back, with stainless steel barrel bands that cinch the structure together without exposed fasteners- the same joinery approach used across SaunaLife’s broader CL-series lineup. The kit includes foundation cradles, so the sauna sits level on a gravel pad, pavers, or a small concrete slab without requiring a poured perimeter foundation.
SaunaLife Wood-Burning Hot Tubs
These wood-fired hot tubs arrive completely assembled and are straightforward to set up. The ergonomically shaped fiberglass tub comfortably seats up to 6 people. The interior surface is easy to clean, and the exterior is crafted from thermally enhanced spruce for weather resistance and durability.
SaunaLife Cold Plunges
Pre-assembled for easy installation, the Thermo-Pine wood exterior will last up to 2X longer than cedar and offers superior thermal resistance. The spacious fiberglass tub is contoured to your body, with a 200-gallon water capacity. Matching Thermo-Pine stairs make entry and exit easy. SaunaLife cold plunge models pair naturally with the CL3G for contrast therapy sessions.
