TimberIN Nordic Modular Spa™

From: £4,620

TimberIN Nordic Modular Spa™. Nordic Modular Spa is a coordinated system of Modules A, B and C that can form a sauna, dressing space, hot-tub zone or one of the listed combined and corner arrangements. It is intended for projects that need a tailored floor plan without designing every component from nothing. The selected module combination defines the real product, foundation and service routes; images of another arrangement should never be used as the construction specification. Nordic Modular Spa has seven exact layouts from a 2,490 × 2,100 mm, about-650 kg single module to 4,980 × 4,600 mm or 7,470 × 2,100 mm three-module systems around 1,950 kg. Sauna modules seat 4–6; the hot-tub module has a 1,800 mm bath, AISI 304 integrated stove or 6 kW electric/filter heat, leather cover, 12-jet air massage and LED. Sauna heat is 20 Pro/20 SL wood or 9 kW Cilindro.

Product Description

A garden spa assembled from purpose-defined modules · Combined garden wellness room

TimberIN Nordic Modular Spa™: sauna, dressing and hot-tub spaces arranged to suit the project

Modularity creates planning freedom, not unlimited interchangeability

Each module has a defined role and combines with the others in listed ways, allowing a small project to focus on one function or a larger garden to build a complete sequence of changing, sauna and bathing. The corner arrangement can respond to boundaries or create a sheltered courtyard feel. Once modules are selected, however, their openings, roof lines and equipment positions become a coordinated structure. Sauna heat, hot-tub heat, water treatment, drainage and electricity remain separate systems that must retain safe clearances and independent maintenance access.

Seven modules with published dimensions and weights

Modular Spa is the catalogue’s clearest system product. Module A is a sauna, B a dressing room and C a covered hot tub; AB, AC and ABC combine them in straight or corner plans. Each module is about 2,490 × 2,100 mm and approximately 650 kg, so the two-part systems are around 1,300 kg and the three-part systems around 1,950 kg. This modular arithmetic makes foundation and delivery planning more transparent than a vague custom building.

Module A — sauna 2,490 × 2,100 mm; approximately 650 kg; 4–6 people; 42 mm three-layer solid wood plate
Module B — dressing room 2,490 × 2,100 mm; approximately 650 kg
Module C — hot tub 2,490 × 2,100 mm; approximately 650 kg; 1,800 mm inside-diameter bath
Module AB or AC 4,980 × 2,100 mm; approximately 1,300 kg
Module ABC straight 7,470 × 2,100 mm; approximately 1,950 kg
Module ABC corner 4,980 × 4,600 mm; approximately 1,950 kg
Sauna heaters Harvia 20 Pro, 20 SL or Cilindro 9 kW
Tub heat/equipment AISI 304 integrated stove or 6 kW electric heater/filter; leather cover, 12-jet air massage and LED

Buy only the modules that solve the daily sequence

A is the pure sauna. AB adds dry changing and storage without a tub. C is the standalone covered hot-tub pavilion. AC gives the direct hot-cold/wet wellness pairing but no dedicated changing room. ABC is the complete guest journey; the straight layout suits a long boundary and the corner version creates a courtyard. More modules add foundation area, delivery lifts and maintenance interfaces. Choose the route people will use every week rather than the most complete diagram. For Module C, decide wood versus 6 kW electric heat before services are routed.

Included systems are different in each module

Sauna Module A includes the panoramic window, glass door, Thermo-Aspen benches, black metal roof and LED/dimmer; the heater is selected separately. Dressing Module B carries the same architectural language without heat. Hot-tub Module C includes cover, air massage, LED and sand filter, then requires the heater choice. Wood heat provides stronger cold-fill recovery and chimney work; 6 kW electric is cleaner but slow for a cold 1,800 mm tub. Each module needs independent service access even when visually joined.

What the current configurator identifies as included

Module A: Sauna includes: (1) Panoramic window; (2) Glass entrance door; (3) Thermo-Aspen benches; (4) LED – 12 V + wireless dimmer; (5) Black metal roof

Module B: Dressing room includes: (1) Panoramic window; (2) Glass entrance door; (3) Thermo-Aspen benches; (4) Black metal roof

Module C: Hot tub includes: (1) 1800 mm inside diameter fiberglass bath; (2) Insulated leather lid; (3) Air bubble massage system; (4) LED lighting; (5) Black metal roof (6) Sand filter

Included equipment is valuable because it establishes a usable baseline. Displayed builds may contain additional systems, so the accepted quotation should repeat every included item.

Additional options for Module A: Sauna

  • Wood burning Harvia 20 PRO heater + chimney + stones
  • Wood burning Harvia 20 SL heater + chimney + stones
  • Electric Harvia Cilindro 9 kW heater + stones

Advantages: Wood-fired Harvia options give a traditional fire-and-stone routine, while the Cilindro electric option offers cleaner thermostat-led control. The right choice follows the Module A hot-room volume, desired loading position and available power.

Additional options for Module C: Hot tub

  • Integrated wood fired stove
  • Electric heater 6 kW

Advantages: The integrated wood stove gives Module C independent fire-led heating without a large electrical load; the 6 kW electric option offers cleaner thermostat control and scheduled use.

The sauna and hot tub run on different clocks

Do not promise one readiness time for AC or ABC. The sauna heater warms air, timber and stones; the tub heater raises well over a tonne of water. A 6 kW tub heater is suited to scheduled holding rather than rapid cold-fill response, whereas the integrated wood stove follows fuel and weather. The 4–6-person sauna’s time depends on glazing and selected Harvia model. Commission each system separately, then build an operating routine that sequences filtration, bathing, ventilation and drying.

Freeze the module plan before foundations and service trenches

Mark the exact chosen arrangement on the site, including door swings, steps, heater access and circulation between wet and dry zones. Design the base for varying loads, particularly beneath a filled hot tub, and route water away from timber thresholds. Confirm how each module will be delivered and joined, with space for lifting and weatherproofing. Electrical supply, chimneys, ventilation, drainage and filtration should be coordinated on one service drawing. Leave removable access where pumps, controls and connections will need inspection after landscaping is finished.

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.
