Bring friends together in the Barrel Sauna Vidar — a compact 3.1m² eco-friendly ThermoWood barrel sauna built for 3–4 people. Its round glass wall frames your garden view while the curved barrel shape distributes heat evenly for a genuinely relaxing session, and the low-maintenance build means more time enjoying it and less time looking after it.
Vidar is built from heat-treated ThermoWood — a durable, eco-friendly alternative to pressure-treated timber that's dimensionally stable, so the metal barrel bands never need re-tightening. It needs no immediate treatment, just a yearly oil to maintain its natural tone (untreated spruce parts come with protective oil included). A bronze-tinted tempered glass door and two side windows keep the interior bright while holding heat well, and you can pair it with an electric stove for quick, consistent heat or a wood-burning stove for an authentic crackling-fire session.

How much maintenance does the ThermoWood need?
Very little — it's a low-maintenance sauna that just needs oiling around once a year, and the wood is dimensionally stable so the bands never need re-tightening.
Is Vidar a good compact option for a smaller garden?
Yes — at 3.1m² it's a compact eco-friendly sauna that still comfortably seats 3–4 people.
Can I run it on electric power?
Yes — Vidar is compatible with an electric stove for quick, consistent heat, or a wood-burning stove for an authentic experience.
How long until it's ready to use?
Vidar is ready to use in just a few days after construction, once your base is prepared and the kit has been delivered.
