Because the furnace sits outside the tub, the entire interior stays free for bathers, and cleanup is fast thanks to the plastic liner. Thermally modified wood resists rot, mould, and insects far better than untreated timber, so this hot tub is built to handle years of outdoor use with minimal upkeep. No electrical hookup or council permit is needed — set it up on any flat, load-bearing surface and start soaking the same week it arrives.

Position the tub on a flat, stable surface. Connect the external furnace using the supplied fittings — this takes roughly 10 minutes. Fill the tub with water, light a wood fire in the furnace, and allow 2–4 hours for the water to reach bathing temperature. Use the built-in bench and platform steps for comfortable, safe entry and exit.

Barrel Saunas builds outdoor bathing products designed for real climates and real use. Every Thermo Spruce Wood Hot Tub is backed by a 3-year warranty, pressure-tested furnace welds, and a design proven across thousands of installations. We handle sizing, delivery, and setup guidance so you can go straight from unboxing to soaking.

Drain the tub using the built-in water tap after each use or before extended storage. Wipe down the plastic inner liner with mild soap and water to prevent mineral buildup. Treat the exterior wood with wood oil annually to maintain its weather resistance, and keep the furnace's ash chamber clear for efficient burning.
