The SaunaLife Model S4B Wood Burning Hot Tub is the ideal choice for smaller backyards, couples, and intimate groups. Up to 6 bathers, 304 gallons of water, zero electricity, and a Black Thermo-Spruce exterior that pairs with any landscape aesthetic. The same dual-chamber stove technology that makes the S6B the fastest-heating tub in its class powers the S4B — 40°F to 95°F in under 2 hours, no hookup required.

Fully assembled. Drop it on a level surface, fill it with a garden hose, light the stove. That's the entirety of setup.
