TimberIN Nordic Core™

Hi Albertas, as promised, I’ve attached some photos of our Hot Tub. We’re not on Facebook or the other social media platforms, but we’re happy for you to use any you might want for your website. It arrived Friday morning 4th April and we were in the water and enjoying it on Saturday evening. We’ve been in it every night since! A big thank you to you and your team. The specification is exactly as planned, and the workmanship is excellent. You might welcome some feedback on a couple of relatively minor issues, which I hope you will find helpful. We only received 4 pictures of the hot tub, but in all honesty, these weren’t really enough for us to confirm that we would be happy with the product before making the final payment. We trusted the process and made payment, but it would have been better if we could have seen images of the liner and also inside the electric cupboard and the insulati…

Product Description

A square acrylic shell with a choice of heater positions

TimberIN Nordic Marble™ Square brings a 4–6-person acrylic shell together with timber cladding and wood-fired or hybrid heating. It is a fixed-size model: choosing the heater changes the equipment arrangement, rather than the shell dimensions. The acrylic finishes distinguish it from the fibreglass Nordic models.

Dimensions and space planning

External dimensions2,200 × 2,200 mm
Indicative capacity4–6 people

Water volume and empty weightConfirm for the final build; not established in the FR source

Allow more than the shell footprint for steps, the cover, equipment and service access. An external stove also needs its own space and the clearances specified in its manual. Obtain the final drawing and filled-load information before preparing a base or arranging lifting.

Six heatings, with the external 28 kW or the integrated 35 kW AISI 316 stove

External wood stove — 28 kW

The AISI 316 external stove keeps the fire and servicing outside the bathing shell. Leave space beside the tub for the stove, connections and safe access.

Integrated wood stove — 35 kW

The AISI 316 integrated stove gives a more compact equipment arrangement. Follow the chimney and operating clearances in the supplied manual.

Hybrid — either stove plus a 6 kW electric heater

Heat up with wood, then keep the temperature with the 6 kW electric heater (Wi-Fi compatible). It runs on 220 V single phase (26 A) or 380 V three phases (14 A); a more powerful 9, 12 or 15 kW three-phase heater is available. Have the supply designed by a qualified electrician.

Hybrid — either stove plus the Poolex heat pump

Heat up with wood; the Poolex Spawer O’Spa 5 kW Wi-Fi heat pump keeps the temperature and can also cool the water in summer. The sand filter is required with the heat pump and is added automatically.

Each stove is available alone, with the electric heater or with the heat pump: six heatings in all.

A single heating time cannot describe every installation. Initial water temperature, weather, cover use and heating method all matter. Keep the cover on during heating when permitted by the operating instructions.

Timber and acrylic finishes

Six claddings: spruce, larch, Thermowood, oak, WPC black or WPC brown (wood-plastic composite). The two acrylic finishes are pearl white marble (standard) and bronze marble, at no extra charge. These are acrylic finishes for this model, rather than the six fibreglass colours offered on some other Nordic tubs.

Included equipment, covers and steps

A wooden drinks shelf, a metal chimney guard and a mixing paddle are included, with wall and bottom insulation at no extra charge. Choose an insulated leather lid (£490) with any cladding, or a wooden round edge with a wooden lid (£490) with spruce or Thermowood cladding only. A fibreglass cover is not available for this model.

Type A wooden stairs are a separate option (£190). Review the order summary to confirm the supplied set.

Filtration, massage, lighting and controls

Water care

A sand filter with a wooden box is selectable; it is required with the heat-pump hybrids and is added automatically. Confirm the actual filtration equipment and maintain water according to its instructions.

Massage

Hydromassage and air massage are separate options, allowing the bathing experience to be configured to the project.

Lighting

Choose two or four LEDs. Confirm the supplied arrangement and modes if these matter to the installation.

Smart SPA

Wi-Fi modules are available for air massage, water massage, filtration and electric heating. Select the corresponding equipment as well; the controller does not supply the system it controls.

Installation and delivery

Use a stable, level base designed for the filled tub, people and equipment. For emptying, the UK selector preselects an external water tap (£70), which you can untick, or offers a tap with a quick adapter for a garden hose (12.5 mm and 15 mm, £95). Plan a suitable discharge route before installation.

Confirm the delivery address, vehicle access, unloading arrangements and movement to the final base before ordering. The UK selector has no separate driver-unloading option; do not assume delivery includes final positioning.

The UK configurator uses its own delivery zones and charges. Agree the route, gates, lifting requirements and final equipment position before delivery.

Looking after the tub

Maintain the timber finish according to its treatment and exposure. Follow the supplied instructions for water chemistry, filtration, cleaning the acrylic and maintaining the heater. Protect all water-bearing components against frost and drain them when the operating guidance requires it.

Choose this model for a square acrylic shell and two marble-style finishes. Nordic Core offers a round alternative, while Nordic Square provides more size choices.

Frequently asked questions

The selected configuration, final drawing and accepted order documents take precedence for the product supplied.

It measures 1,700 × 1,700 mm internally and 2,200 × 2,200 mm externally, with an indicative capacity of 4–6 people.

Six: the 28 kW external or the 35 kW integrated AISI 316 stove, each alone, each with a 6 kW electric heater, or each with the Poolex Spawer O’Spa 5 kW Wi-Fi heat pump (the sand filter is required with the heat pump).

An external stove keeps the heating equipment beside the tub and needs additional space. The integrated version provides a more compact arrangement. Confirm access and clearances for either choice.

A wooden drinks shelf, a metal chimney guard and a mixing paddle, plus wall and bottom insulation at no extra charge. Type A stairs (£190) and the external water tap (£70, preselected) are options; confirm the complete order.

An insulated leather lid (£490) with any cladding, or a wooden round edge with a wooden lid (£490) with spruce or Thermowood only. No fibreglass cover is offered.

Six claddings — spruce, larch, Thermowood, oak, WPC black and WPC brown — and pearl white marble (standard) or bronze marble acrylic at no extra charge.

They are separate selectable options. Smart SPA control modules also require the corresponding equipment.

The 6 kW electric heater runs on 220 V single phase (26 A) or 380 V three phases (14 A). The optional 9, 12 and 15 kW heaters need a three-phase supply. Have the supply designed by a qualified electrician.

Use the UK delivery-zone selection and agree access, unloading and movement to the prepared base. The UK product has no separate driver-unloading option.
