Nordic spruce swells naturally when filled with water, forming a 100% watertight seal without sealants or chemicals. The internal furnace keeps the design compact and efficient, and this hot tub requires no building permit or concrete base — place it anywhere firm and level, and relocate it whenever you like.

Every Barrel Saunas hot tub passes material inspection and final quality testing before dispatch, backed by a full 3-year warranty and pressure-tested furnace welds — built for genuine year-round outdoor use.

Drain the tub through the wooden bathtub plug after use or before long storage. Rinse the interior to prevent mineral buildup, and apply wood oil to the exterior annually to preserve its weatherproofing.
