Description
The Medium Wood Barrel Sauna with Window is Finnmark Sauna’s own flat-packed outdoor barrel for 4–6 people, its 6.7 m³ sauna room formed from 40 mm Nordic thermo spruce staves and finished with a half panoramic window in the upper rear panel that opens the bathing view to your surroundings. The timber is thermally modified by Thermory without chemicals, which makes it exceptionally resistant to rot and moisture, dimensionally stable and light enough to handle easily during the build. Natural light also enters through a full-height 8 mm tempered glass door, two thermo aspen benches face one another inside, and bitumen roof shingles are included in the kit. It is sold without a heater, with the HUUM HIVE Mini 10.5 kW electric heater package including the UKU glass Wi-Fi controller and sauna stones, or with the wood-burning barrel kit pairing the Kuru 20 heater with heat shielding, a flue kit and stones. Delivery to most mainland UK postcodes is included, and the kit is designed for competent DIY assembly, with an assembly service available by quotation. The windowless version is sold separately as the Medium Wood Barrel Sauna (4–6 Person), and the compatible lighting kit, paraffin oil and exterior wood treatments are also sold separately.

Assembly
The sauna arrives flat-packed as a DIY kit with step-by-step English instructions, and the manufacturer recommends two people for the build. The glass door is deliberately supplied without a lock to prevent accidental entrapment; in high winds it should be held closed with a heavy object placed outside. An assembly service is available by quotation, and the assembly instructions can be read in the Downloads tab before you buy.
Foundations
The barrel must stand on a firm, level base that remains free of standing water after rainfall; concrete, pavers or compacted gravel are preferred. The supplied foundation beams keep the staves clear of the ground.
Heater options
The dropdown offers the barrel without a heater, with the HUUM HIVE Mini 10.5 kW electric heater package (UKU glass Wi-Fi controller and sauna stones included), or with the wood-burning barrel kit (Kuru 20 heater, heat shielding, flue kit and stones). A wood-burning heater takes up more bench space than an electric model, so plan for the lower end of the stated capacity; for commercial set-ups we recommend a commercial heater. Electrical work, including installation of an electric heater, must be carried out by a licensed electrician. The barrel is an uninsulated outdoor structure, so weather conditions through the seasons will influence heat-up times.
Timber
Thermory’s Nordic spruce is kiln-dried, x-rayed for internal flaws and then modified with heat and steam alone, with no chemicals involved. The process leaves the timber highly resistant to rot and moisture, dimensionally stable and lighter to handle, with a brushed texture and distinct knots; left untreated outdoors it gradually weathers to a grey patina.
Care
Treat the interior timber with a specialist sauna finish before first use and protect the exterior each year with a UV protection oil or exterior wood stain; paraffin oil for the interior is sold separately. Ventilate and dry the sauna after every session and never clean the interior with a pressure washer or running water. The full usage and maintenance guide is in the Downloads tab, and following it keeps the warranty valid.
Brand
This barrel is part of Finnmark Sauna’s own-brand outdoor range, designed by a UK sauna specialist and built from Thermory thermo timber.
Warranty
A 2-year manufacturer’s warranty covers the timber structures and housings. The usage and maintenance guide in the Downloads tab sets out the care needed to keep it valid.
Ordering & Delivery
The sauna ships flat-packed in an OSB crate measuring 125 × 227 × 102 cm. The price includes Moffett (vehicle-mounted forklift) delivery to most mainland UK postcodes, typically within 3–8 working days once despatch is agreed; offshore and exception postcodes are quoted individually. The Delivery & Returns tab carries the full policy.
