Product Description
A round hot tub with the heater outside
TimberIN Nordic™ External Comfort is a round fibreglass hot tub with its heater placed beside the tub, not inside it. The whole bathing space is free for bathers, and you choose how to heat it: wood, electricity, pellets, gas, a heat pump or a combination.
Two sizes
| Size | Inner diameter | Outer diameter | Height | Bathers | Water |
|---|---|---|---|---|---|
| 180 cm | 1,802 mm | 2,000 mm | 1,064 mm outside, 964 mm inside | 4–6 people | about 1,400 litres |
| 200 cm | 2,042 mm | 2,240 mm | 1,064 mm outside, 964 mm inside | 6–8 people | about 1,550 litres |
The 180 cm suits most gardens; the 200 cm gives a larger group more room.
Choose your heating
Every size and cladding comes with the same eight heating options:
- Wood-fired – an external 22 kW stove in AISI 316 stainless steel.
- Electric – a 6 kW heater on a normal single-phase supply, with 9, 12 or 15 kW versions on three-phase for faster heating. No chimney and no firewood: an easy all-electric hot tub.
- Hybrid with electric – the wood stove plus the 6 kW electric heater: heat up quickly with the fire, then hold the temperature electrically.
- Hybrid with a heat pump – the wood stove plus a 5 kW Wi-Fi heat pump that can also cool the water in summer.
- Pellet – an external 30 kW AISI 316 pellet stove you control from your phone.
- Gas or a 19 kW bioheater.
- Connections only – 50 mm connections with closing valves, ready for a heater of your own.
Cladding, shell and lids
The outside comes in spruce, larch, Thermowood, oak, or low-maintenance WPC in black or brown. Inside, choose a fibreglass shell in white, blue or grey, a pearl or granite finish, or upgrade to a glossy acrylic shell. Wall and bottom insulation are included at no extra charge.
For the top, pick a fibreglass lid, an insulated leather lid that keeps the heat in best, or a wooden round edge with a wooden lid (Spruce or Thermowood only).
Make it yours
Add air-bubble massage, hydromassage, sand filtration in a wooden cover box, and two or four LEDs. Wi-Fi smart kits let you run the massage, filter and electric heater from your phone. A chimney guard and an ash shovel and rake are available for the wood and pellet stoves. A drink holding side shelf and a wooden paddle are included. Wooden stairs are available as A type (£190) or C type (£290), and an external water tap can be added.
Planning your space
Allow about 3 × 3 m for the tub and the heater beside it, with room for the chimney and service access. A filled tub with bathers needs a solid, completely level base. The tub is delivered assembled; check access for the lorry and plan how it will be moved to its final place. An electric or hybrid heater must be connected by a qualified electrician.
Frequently asked questions
Which size should I choose?
Count the people who will usually bathe together: the 180 cm seats 4–6, the 200 cm seats 6–8. Then check that the tub, the heater beside it and the chimney fit your space and the delivery route.
Can I have an electric hot tub without a stove?
Yes. Choose the electric heating option: a 6 kW heater runs on a normal single-phase supply, and 9, 12 or 15 kW versions are available on three-phase. There is no chimney and no firewood.
Which heating options are available?
An external 22 kW wood-fired stove, a 6 kW electric heater (9–15 kW on three-phase), hybrids of the wood stove with the electric heater or with a heat pump, an external 30 kW pellet stove, gas, a bioheater, or connections for a heater of your own.
What electricity supply does the electric heater need?
The standard 6 kW heater runs on single-phase (220 V, 26 A) or three-phase (380 V, 14 A) on its own circuit fitted by an electrician. The 9, 12 and 15 kW versions need three-phase.
Why is the heater outside the tub?
With the heater beside the tub, the whole shell is free for bathers and the heater is easy to reach, clean and service. Plan space for it next to the tub.
Which cladding needs the least care?
WPC in black or brown needs the least maintenance. Thermowood and larch weather well, spruce is the classic choice, and oak gives the richest look.
Which lid should I choose?
The fibreglass lid is a durable everyday choice. The insulated leather lid keeps the heat in best and is light to lift. The wooden round edge with wooden lid is available with Spruce or Thermowood cladding.
Is insulation included?
Yes. Wall and bottom insulation are included at no extra charge.
How should I protect the tub in winter?
When the tub is not in use in freezing weather, drain it, remove and store the filter indoors, clear the water from the massage systems and drain the heater, following the manuals supplied with the equipment.







































































































Everything is fine! Delivery was perfect and the driver helped us install the tub in the target place.
The product as such is also great. We had the opportunity to use it the first time yesterday. The only issue is to keep water temperature on the desired level – we made it too high :-).
All the best in New Year,
We have, indeed, installed our spa… and we absolutely love it. The build quality and standard of materials are even better than we had hoped. The fact that we could order the spa without pumps or air jets was also fantastic; this way we can simply sit in lovely warm water and enjoy the peaceful Scottish Highlands with as little background noise as possible.
Thank you and all of your staff for making such a good quality product,
Alan
Dear Albert
Thank you so much for our hot tub. We absolutely love it. It is really high quality and we are delighted. It was worth the wait and your amazing team kept us up-to-date all the way along so we were not worried by the delays. It was a little nerve wracking sending money across to Europe but lots of your other customers had written on their reviews that it all worked out well and and we too were very happy in the end. We just had to pay import VAT into the UK because of Brexit but again we were expecting that. Here are some photographs. Thank you again to you and your team for everything

Hello Evelina,
Here are some pictures of our hot tub. We are very pleased with its performance, the wood -burner heats the water quickly and the electric heater maintains the temperature over an extended period if required . This was the only wooden tub we could find with insulation and we’re impressed that it holds its temperature well when both heaters are off. Throughout the process of ordering and delivery we were kept informed promptly with help and information.
We are happy for you to use the photos and the above statement for your customers. We’ve added a small modification as you will see from the photo of lid. The rim of the lid was scratching the edge of the tub so we slit some alkathene pipe of the same colour and attached it, with good results. We’ve also attached two stainless steel wires to stabilise the high chimney and protect it from strong winds.
Regards, Fran and David
Please find attached photos of out new hot tub. We have put the wood burner inside our garden room with the pipes going through the wall to the hot tub, so it heats the room and the hot tub.
So far very pleased with it- the man who delivered it was excellent and very helpful
Dear Albert,
It has been now a good few months that we have had the use of our sauna and hot tub. The sauna works perfectly and we are very happy – I believe we have sent you pictures in the past? I attach another picture for you of how both the sauna and hot tub are now happily sitting in our garden.
Dear Albert and Timberin Team, I hope you’re well. I send some photos of the SPA. The installation was delayed because the technician must be out for a few weeks. We wanted to put grass around and so we had to wait for the laying and the grass to consolidate. At this moment we only need to connect the Blue Lagoon system. Meanwhile I and my daughters have already tried and we loved! Congratulations and I will recommend you to everyone I know here! Best regards, Luis
Timberin company is worth recommending. Everything was done in accordance with the order, on time. The bathtub looks beautiful in the garden, it is always used. After-sales service is the most important and the best. Exemplary contact, replies to e-mails almost immediately. I recommend it again.
Longer delivery time because of covid19 but it was worth waiting for this high quality hottub. Enjoy!
Hello Albertas
Yes we have used the spa with the wood burner thank you, and it’s lovely. I thought photos of it with lights and bubbles in action would be best. However, here is the first photo taken by my husband… showing mostly the view rather than the tub.
