Wood-Fired Hot Tubs: The Authentic Nordic Spa Experience
Share
There's a reason wood-fired hot tubs have such a devoted following: no electricity bill, no plastic hum of a pump motor, just the crackle of a real fire heating real water. It's the closest thing to a Scandinavian spa ritual you can build in a British back garden.
For families, the Barrel Saunas Family Larch Wood Spa Hot Tub (Ø1.7m) is our most popular size — a 4-person round tub crafted from Siberian larch with an internal furnace, so no external plumbing is needed. If you regularly host bigger groups, the Large Larch Wood Hot Tub (2m, up to 10 people) uses an external log-fired furnace, keeping the fire and smoke away from the bathers while still delivering a proper soak for a crowd.
Wood-fired tubs typically take 1.5–3 hours to heat from cold depending on size and outside temperature, but many owners see that as part of the appeal — it becomes an evening ritual rather than an instant convenience. Because there's no motor or electronics involved, maintenance is simpler and the tubs tend to last for years with basic timber care (a wood oil treatment 1–2 times a year keeps the staves looking new).
If your priority is off-grid capability, lower running costs long-term, and that unmistakable campfire-and-hot-water combination, a wood-fired hot tub is hard to beat.
