TimberIN Nordic Barrel Duo™

From: £11,110

TimberIN Nordic Barrel Duo™. Nordic Barrel Duo combines a cylindrical barrel sauna with a hot tub in one 5400 × 2450 × 2470 mm structure. It is intended for gardens and hospitality projects that want heat, cooling and bathing within a single coordinated installation rather than two unrelated products. The fixed envelope and timber choice must be checked against access and foundation plans, while sauna heating, hot-tub heating, drainage, electrical equipment and chimney routes remain separate technical systems. Barrel Duo is one 5,400 × 2,450 × 2,470 mm two-zone mobile sauna in spruce or Thermowood, with an optional braked double-axle trailer rated up to 2,000 kg. The live page does not link a model-specific technical sheet or heater menu, so occupancy, room split, dry/plated mass, bench dimensions, heater output and road-legal completed specification must be stated in the quotation.

Product Description

Sauna and hot tub in one coordinated barrel structure · Combined garden wellness room

TimberIN Nordic Barrel Duo™: two outdoor rituals organised within a fixed 5400 mm plan

A shared architectural shell, but two independently demanding spaces

The barrel section gives the sauna its familiar curved walls and compact air volume, while the adjoining bathing area creates a natural sequence between dry heat and open-air water. Bringing the functions together saves visual fragmentation and can simplify the guest journey, but it does not merge their engineering. The sauna heater needs its own ventilation and safety clearances; the hot tub needs filling, drainage, circulation and water care; each combustion appliance needs an approved chimney and service approach. Timber selection applies to the whole composition and affects colour, weathering and maintenance.

A 5.4-metre mobile building whose completed mass must be proven

Nordic Barrel Duo is defined by its long 5.4-metre body and two-zone concept rather than by a list of interchangeable lengths. The current dimensions are 5,400 × 2,450 × 2,470 mm, already close to transport-sensitive width and height. Adding the optional braked double-axle trailer creates a complete road-going assembly, but the configurator’s “up to 2,000 kg” trailer rating is not the same as the actual plated mass of the finished sauna.

The meaningful choice is material and whether mobility is genuinely required

Spruce gives a lighter, traditional barrel appearance and usually the simplest material route. Thermowood creates a darker, heat-treated exterior with different weathering and maintenance character. The trailer only makes sense where the sauna will move between sites; if it will remain in one garden, a fixed foundation removes towing, axle, registration and levelling constraints. For mobile use, the room partition, heater, chimney stowage and all loose interior items must be designed around transport, not added after the body is mounted.

The trailer is not an accessory in the ordinary sense

A double axle can improve stability and provide more load margin than a light single-axle chassis, appropriate for a 5.4-metre building. Plan for the additional purchase cost, tyre and brake maintenance, turning space and legal responsibility. The final tow vehicle, nose weight, axle loads, overall width, insurance and licence must be checked against supplied documents. At every venue, level and secure the sauna before firing; provide safe steps, a chimney zone and a cool-down procedure before travel.

Additional options

  • Trailer with the double axle with brakes (total weight up to 2000 kg)

Advantages: A braked double-axle trailer offers useful load margin and road stability for a longer mobile sauna while keeping the complete unit relocatable.

Warm-up depends on the unreported heated-room volume

No responsible warm-up time can be stated from the outside length alone. A dressing or changing zone reduces the heated section; glazing, insulation, ambient temperature and the final heater then determine the result. Ask for the heated cubic metres, stone mass and approved heater model in the quotation. For commercial mobile use, record the commissioned warm-up at several outdoor temperatures and schedule conservatively rather than promising a generic number of minutes.

Coordinate the complete wellness circuit before the base is built

Set out the full 5400 × 2450 mm footprint together with steps, doors, stove access and any equipment enclosure. The foundation must support the building and the concentrated filled hot-tub load without differential movement. Confirm the route for delivery or lifting, because a combined structure cannot be treated like two small parcels. Plan clean-water supply, controlled drainage, electrical isolation, fuel storage and maintenance panels. For hospitality use, separate guest circulation from hot fireboxes and document sauna cleaning, water treatment and daily safety checks as one operating procedure.

Before production: TimberIN products are individually made, so published measurements are approximate. Confirm the selected live variation, final dimensions, included equipment, service requirements, delivery method and any critical tolerances in the accepted written quotation. Photographs may show optional equipment.

Questions about TimberIN Nordic Barrel Duo™

What woodtype choices are shown for TimberIN Nordic Barrel Duo™?

Woodtype choices currently shown are Spruce; Thermo Wood. Availability and valid combinations are controlled by the live configurator and confirmed in the final written order.

Not necessarily. The displayed amount follows the current base or selected configuration. Size, material, heater, equipment, delivery and installation choices can change the total; the basket, quotation or written order is the final commercial record.

What should be confirmed before delivery of TimberIN Nordic Barrel Duo™?

Confirm the exact module or combined floor plan before designing the base, terrace openings or service routes. Allow independent maintenance access for the sauna heater, hot-tub heater, filtration, drainage and electrical equipment. Check the complete delivered dimensions and weight against access, lifting, foundation and local siting requirements. Final dimensions, included equipment and site responsibilities should be confirmed before production or dispatch.
