Description

The SaunaLife Model S1B Cold & Hot Immersion Tub delivers professional-level recovery in a compact, luxury outdoor design finished in bold Black Thermo-Pine.

Engineered for both cold plunge therapy and hot water immersion, the S1B allows you to switch between invigorating cold exposure and soothing heat therapy — ideal for post-workout recovery, stress reduction, and sauna contrast bathing.

Its enhanced Thermo-Pine exterior lasts up to 2X longer than cedar, offering superior durability and thermal resistance in outdoor environments. Inside, a thick, ergonomically contoured fiberglass insert holds 124 gallons of water, providing deep, full-body immersion in a space-efficient footprint.

Arriving fully assembled and including matching black Thermo-Pine stairs, the S1B is built for homeowners who want professional-grade immersion therapy without complicated installation.

This is compact luxury recovery — built to perform.

Optional water chiller system (sold separately)
