Product Description
TimberIN Nordic Barrel Duo™: sauna and hot tub together
Barrel Duo places a traditional barrel sauna, a covered seating area and a round hot tub in one continuous Thermowood structure. Its 5.4 m length brings both experiences together without requiring two separate buildings. The sauna and tub retain distinct capacities, allowing a group to use them in turn or divide between the two spaces.

Two coordinated heating systems
Wood-fired package
The hot tub has an integrated wood stove and the sauna a Harvia M3 with chimney. Plan fuel storage, clearances, cleaning and practical access to the appliances. The tub-stove output and material are confirmed in the order documents rather than inferred from another model.
Electric package
The tub has a 6 kW electric heater and the sauna a 9 kW Harvia Cilindro PC90. These are separate appliances, and the filtration, air massage and lights must also be included in the electrical design.
Prepare the electrical installation
The wood-fired package also needs electricity for LEDs, air massage, sand filtration and UV treatment. A qualified electrician must design suitable outdoor circuits, earthing, cables and protection from the actual equipment ratings and manuals.
Hot-tub comfort and water care
The moulded tub includes air massage, LED lighting and an insulated leather cover. The cover limits heat exchange and helps keep debris out when the tub is not in use. Sand and UV filters are included together in both packages; leave access for inspection, cleaning and winter care. Follow the supplied component instructions for filtration operation, water treatment and seasonal maintenance.
A barrel sauna for 2–4 people
The sauna includes the benches shown for the model, ventilation, interior lighting, a wooden door with glazing and a rear panoramic window. Exterior LEDs light the approach and transition area. The 42 mm Thermowood construction creates the continuous barrel profile.
The covered area between sauna and tub provides a place to sit briefly or leave belongings when moving between the two experiences, while keeping the hot room distinct from the bathing area.
Base, access and service connections
Use a level, stable support designed for the complete operating load. The approximate 1,300 kg before filling does not include the water or users. Check access width, turns, overhead clearance, ground capacity, truck manoeuvring space and the lifting area before production.
The final drawing must guide the base and service positions. Plan filling, controlled drainage, electrical connections, appliance clearances and access to the filtration and other technical equipment.
Factory-assembled delivery
Barrel Duo is delivered assembled. Delivery is quoted separately from the postcode and is not automatically included in the displayed price. The customer provides suitable mechanical unloading and arranges final positioning on site. Confirm the lifting capacity, reach, ground conditions and truck approach before dispatch; final placement is included only if a specific service is written into the quotation.
Optional braked trailer
The UK selector offers a braked double-axle trailer at £4,450, labelled for a total weight up to 2,000 kg. This rating does not guarantee that every completed configuration is within that limit. Confirm the actual finished mass, including all selected equipment, before ordering the trailer.
The tub travels empty. Confirm the supplied trailer documents and the requirements for the intended destination, towing vehicle, licence, insurance and any applicable registration before road use.
