Product Description
A moulded fibreglass oval tub for one or two people
TimberIN Nordic Duo suits one person or a couple wanting a moulded fibreglass shell, two facing seats and a direct choice of heating systems. The exterior timber is separate from the bathing surface: configure the appearance, interior colour and equipment around the project.
It is not a fixed all-inclusive spa package. The heater, cover, insulation and spa equipment must agree with the quotation and final order summary.
Dimensions, capacity and geometry
| Detail | Documented value |
|---|---|
| Users | 1–2 people |
| Water volume | 1,000 litres |
| Empty weight | 80 kg |
| Published external-dimensions line | 1,900 × 1,190 × 940 mm |
| Internal height | 920 mm |
| External height stated separately | 1,060 mm |
| Bench width | 300 mm |
The technical sheet gives 940 mm in its external-dimensions line and 1,060 mm as a separate external-height figure. These should not be silently treated as the same measurement. Confirm any critical height, opening, passage or terrace interface on the final drawing for the handmade tub.
The 1,900 × 1,190 mm plan footprint describes the tub itself, not the complete installed system.
Three heating configurations
| Configuration | Documented equipment | Installation effect |
|---|---|---|
| Electric | 6 kW heater with 0–45°C thermostat | Requires a suitable electrical supply and protection |
| External wood | BFTS-50, 22 kW, AISI 316 stainless steel | Keeps the heater outside the bathing area; allow side space and a chimney |
| Hybrid | External 22 kW wood heater plus 6 kW electric heater | Requires both equipment layouts and their connections |
The current UK matrix has no heater-free variation. Four timber choices and three heaters give twelve combinations.
For the documented 6 kW heater, the source specification lists 220 V single phase / 32 A or 380 V three phase / 16 A. A qualified electrician must confirm and size the final connection, cable and protection for the equipment supplied and the site. These source figures do not replace the delivered unit’s instructions.
No fixed heating time is documented. Starting temperature, weather, cover, insulation and the selected heater affect the result.
Shell, cladding and colours
The moulded fibreglass shell has two facing seating areas around a central footwell, visible in the photographs and model visualisation. Massage equipment remains optional.
The UK exterior choices are spruce, larch, Thermowood and oak. The documentation does not provide a numerical performance comparison or one standard finish for these timbers; record the chosen wood and finish in the order.
Interior colours are white RAL 9001, blue RAL 5012 and grey RAL 7015.
Covers and included insulation
Wooden edge and lid
The edge and wooden cover are selected together. The documented cover measures 1,200 × 1,910 mm, weighs 30 kg and may have 30 mm insulation; confirm the exact supplied construction.
Insulated leather lid
A separately priced UK choice. Confirm its dimensions, construction and weight in the quotation.
Wall insulation
Listed on the UK page as included at no extra charge. Record it in the order; material and thickness are not specified in the model documentation.
Bottom insulation
Also listed at no extra charge in the UK configurator. Confirm the supplied construction rather than copying another model’s specification.
Filtration, massage, LEDs and controls
Sand filtration
Offered with a wooden enclosure documented at H800 × W700 × L600 mm. Confirm flow, electrical data and care instructions.
Two massage systems
Water hydromassage and air-bubble massage are separately selectable. Jet or outlet counts and powers are not documented for this exact configuration.
LED lighting
Two or four LEDs can be selected. Confirm colours, modes and suitable placement.
Smart control
Separate modules are available for each massage system, sand filtration and the electric heater. The heater module provides scheduled on/off operation; Wi-Fi coverage is required.
Confirm the control technology and compatible platforms for the supplied modules. Jets, lights or an enclosure visible in a photograph do not establish inclusion.
Confirm the supplied steps and paddle
A-type wooden steps and a paddle appear under “Already included”, but that choice is not initially selected or mandatory. Confirm them in the quotation and final order summary.
The documented movable A-type steps measure H600 × W780 × L830 mm and weigh 15 kg. Include this access area in the site plan.
Base, full footprint and connections
Provide a solid, level base without a slope. Appropriately designed compacted aggregate, timber decking or paving may be suitable depending on the ground and load.
For initial assessment, approximately 2,000 kg including water and users is a conservative planning assumption, not a calculated operating weight or guaranteed maximum. Have bearing capacity and load distribution checked for the site.
Beyond the 1,900 × 1,190 mm tub, allow for the 780 × 830 mm steps; the external heater at approximately 400 × 620 × H670 mm with chimney and clearances; a 700 × 600 mm filter enclosure; a 600 × 600 mm electrical enclosure; cover handling, connections, drainage and maintenance access.
Confirm the complete footprint and clearances before building. A documented one-inch AISI 316 external drain tap is separately offered, alone or with an adapter for 12.5 or 15 mm garden hoses. The UK chimney guard is also a separate option.
Delivery and unloading
The manufacturer reserves H1,290 × W1,400 × L1,950 mm for the main package, weighing 80 kg. A heater or spa-equipment package may add H900 × W800 × L1,200 mm and 15–50 kg. These are transport envelopes; the tub itself is slightly smaller.
The UK selector retains green- and yellow-zone delivery. It has no driver-unloading assistance option. Confirm the supplied assembly state, unloading responsibility and onward handling to the base before dispatch. Check access for the normal 18 m, 40-tonne truck; smaller-truck delivery may be possible in the London area.
Operation, care and warranty documents
The exact product file does not yet establish a detailed routine for the shell, cladding, water and equipment, frost preparation or warranty conditions. Obtain the instructions and terms for the actual heater, filter and selected accessories before delivery rather than applying another model’s routine.
Why choose TimberIN Nordic Duo?
Choose this model for a fibreglass oval tub with two facing seats for one or two people, and a direct choice of electric, external wood or hybrid heating.
The compact polypropylene tub is shorter and offers wood heating with an optional UK electric add-on for hybrid use. Nordic Duo™ Wood instead has wooden floor, walls and benches. The fibreglass Nordic Duo stands out for its larger moulded shell, four exterior woods and three direct heater choices.
Frequently asked questions
The selected configuration, final drawing and accepted order documents take precedence for the product supplied.
What are the dimensions, capacity and weight?
The external-dimensions line states 1,900 × 1,190 × 940 mm, with 1–2 users, 1,000 litres and an 80 kg empty weight. Handmade measurements are approximate.
Why are both 940 mm and 1,060 mm heights stated?
The sheet lists 940 mm within its external dimensions and separately lists 1,060 mm external height, alongside 920 mm internal height. Confirm critical vertical measurements on the final drawing.
Which heating systems are available?
Twelve UK variations combine four woods with 6 kW electric heating, an external AISI 316 BFTS-50 22 kW wood heater, or both as a hybrid.
What supply is needed for electric heating?
The source sheet lists 220 V single phase / 32 A or 380 V three phase / 16 A for the documented 6 kW heater. A qualified electrician must confirm the final circuit, cable and protection against the actual equipment and site.
Can I order it without heating?
No. The current UK matrix contains only electric, external wood and hybrid variations.
Which woods, colours and covers can I choose?
Spruce, larch, Thermowood or oak; white RAL 9001, blue RAL 5012 or grey RAL 7015 shell colours; and a wooden edge/lid or insulated leather lid. Wall and bottom insulation are listed at no extra charge in the UK.
Are filtration, massage, LEDs and smart controls included?
They are separate options: sand filtration, water massage, air bubbles, two or four LEDs and individual control modules. Confirm exact technical specifications and compatibility for the selected package.
Are the steps and paddle included?
They appear under “Already included”, but the choice is not initially selected or mandatory. Confirm them in the order. The A-type steps are documented at H600 × W780 × L830 mm and 15 kg.
What base and space do I need?
A solid, level base assessed for the real installation. Approximately 2,000 kg including water and users is an initial conservative planning assumption. Add steps, heater, chimney, technical enclosures, cover handling and service access to the tub footprint.
What delivery and unloading arrangements are needed?
The main transport envelope is H1,290 × W1,400 × L1,950 mm at 80 kg, with a possible separate equipment package. UK delivery-zone charges do not establish unloading or final positioning; agree these and the assembly state before dispatch.
How long does it take to heat?
No fixed time is documented. Starting temperature, weather, cover, insulation and heater choice determine the actual result.
What maintenance and warranty conditions apply?
Obtain the model-specific shell, timber, heater, filtration and accessory instructions and warranty terms for the ordered configuration. Do not assume another model’s routine applies.


























































































































































Hi
Just to say that I am delighted with my hot tub. We have used it most evenings and it has become the highlight of the day.
If there is one thing I can say about TimberIN, it is thanks for the outstanding service. The whole experience from ordering to delivery went down without problems!
The hot tub we ordered is just for two, but it suits the area that we had to install it in, and it is definitely fun for two, and it looks great in respect of the major deck replacement we had to do prior to delivery.
Yes, there might be some concerns about ordering big ticket items from Eastern Europe, but we had none with the TimberIN team, the workmanship is quality and we only had one minor problem in powering up the tub, due to me being in a hurry.
I highly recommend that before you order. Please consult a qualified electrician regarding the amperage rating of your house mains power panel. We had to change the tub water heater to a lower Kilowatt rating due to the Max rating of 16 amps of our mains panel.
In closing, and in speaking as a retired Medical systems Engineer. You can’t go wrong with TimberIN!
Thanks to you Albert and the the team!
Very good service and very good product. Delivered at the agreed time and looks wonderful in my woods.
