Polypropylene Hot Tub – TimberIN Nordic Flex™ (160–220 cm, Configurable)

From: £2,537

Polypropylene Hot Tub – TimberIN Nordic Flex™ (160–220 cm, Configurable). Nordic Flex combines a smooth polypropylene bathing shell with exterior timber cladding and one of the widest configuration ranges in the catalogue. Diameters from 1600 to 2200 mm can be paired with wood-fired, electric or hybrid heating, allowing the same model family to serve compact gardens, regular family use or hospitality projects. Choose size and heater position together because both alter water volume, seating, service access and the total footprint. Four live diameters span 4–6 to 10–12 bathers and approximately 1,800 to 3,400 litres, with a constant 1,040 mm shell height. Electric, external, internal/snorkel, integrated 35 kW, hybrid and no-heater choices are offered, alongside open/closed polypropylene or timber benches, four stair types, insulation, three exterior timbers, massage, filtration, LEDs and smart controls.

Product Description

A smooth-lined tub with broad configuration freedom · Made-to-order outdoor hot tub

Polypropylene Hot Tub – TimberIN Nordic Flex™ (160–220 cm, Configurable): low-maintenance bathing from 1600 to 2200 mm

The practical interior is separated from the natural exterior

Polypropylene creates a continuous, non-porous bathing surface that is straightforward to wipe and does not need the same water-side timber care as a traditional all-wooden tub. Timber cladding retains the garden character and can be selected for appearance and weathering behaviour. The broad diameter range is useful, but it should not encourage automatic upsizing: larger shells carry more water and take more energy to heat. Heater choice is equally important, with internal systems protecting outside space and external systems preserving more room for bathers.

The full polypropylene size table

Nordic Flex has the broadest genuine configuration range in the hot-tub catalogue. Its non-porous polypropylene shell is available from 1,600 to 2,200 mm, and the technical sheet quantifies how rapidly water volume rises: the largest version holds roughly 1,600 litres more than the smallest. Closed polypropylene benches can reduce the published volume by around 25%, an important distinction for filled weight and heating rather than a minor furniture preference.

1,600 mm 4–6 bathers; approximately 1,800 L; 1,920 mm top outside; approximately 200 kg
1,800 mm 6–8 bathers; approximately 2,280 L; 2,120 mm top outside; approximately 250 kg
2,000 mm 8–10 bathers; approximately 2,800 L; 2,320 mm top outside; approximately 280 kg
2,200 mm 10–12 bathers; approximately 3,400 L; 2,520 mm top outside; approximately 300 kg
External height Approximately 1,040 mm all sizes; bottom insulation adds about 70 mm
Bench-volume effect Closed polypropylene benches can reduce volume by approximately 25%
Electric choices 6 kW default; 9/12 kW and 15/18 kW increases listed, subject to connection design
Integrated wood heater 35 kW listed in the technical sheet

Open the product technical sheet

Configure in this order: occupancy, benches, heater, then appearance

Start with the people who will normally bathe. Next decide whether reducing volume with closed benches is desirable or whether open access and timber character matter more. External wood heat protects seating but needs garden space; snorkel heat saves outside space and occupies the tub; integrated heat gives a neat outline and more coupled servicing. Electric-only is controllable but slow on a cold multi-thousand-litre fill; hybrid gives flexibility with more infrastructure. The no-heater option is for a separately engineered system, not an incomplete order. Only after these choices should cladding and liner colour lead the discussion.

Decision Choices currently selectable
Inner diameter 1600 mm · 1800 mm · 2000 mm · 2200 mm
Stoves Electric heater · External wood-fired stove, 316-grade steel, chemical resistant · Hybrid: Electric + external wood stove · Hybrid: Electric + internal wood stove · Integrated (316) stainless steel 35 kW wood fired heater (PP) · No heater · Snorkel wood-fired, 316-grade steel, chemical resistant

How to judge the long Flex option list

Wall/bottom insulation and an insulated cover have the clearest energy benefit. Filtration becomes progressively more valuable with larger volumes because draining 2,800–3,400 litres after every short use is wasteful, but the water still needs testing and treatment. Hydromassage is the strongest spa upgrade; air massage is gentler; four LEDs suit 1,800–2,200 mm shells. Higher electric outputs shorten theoretical warm-up but may demand costly supply work. A smart kit is worthwhile for scheduled filtration or electric heat only where outdoor Wi-Fi is dependable.

What the current configurator identifies as included

Already included: Wooden round edge + wooden lid · Insulated leather lid + edge from polypropylene instead of wood

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.

Wood type

  • Siberian spruce (already included)
  • Siberian larch
  • Thermo wood

Advantages: Spruce offers a light traditional finish; larch is denser and visually pronounced; Thermowood is darker and heat-treated; WPC gives a more uniform low-finish exterior where listed.

Electric heater

  • Power level and connection type. Default 6 kW. Select from the table and inform us separately
  • Power increase to 9 kW or 12 kW
  • Power increase to 15 kW or 18 kW

Advantages: Electric heat offers repeatable thermostat control, no fuel storage and a clean holding routine; 9–18 kW upgrades can shorten recovery when the selected water volume and electrical design justify them.

Type of benches

  • Wooden benches
  • Wooden benches (sunny type)
  • Polypropylene open benches
  • Polypropylene close benches

Advantages: Open polypropylene benches retain inspection access and reduce visual bulk; closed benches displace water and can lower the volume to heat; shaped timber seating provides a more traditional material feel.

Type of stairs

  • Basic 3 stage stairs (Ladder)
  • "B" type stairs
  • "A" type stairs
  • "C" type stairs

Advantages: The correct stair creates a safer, more natural step over the hot-tub rim; broader A, A+ or C forms can provide a more generous landing beside a taller shell.

Insulation options

  • Wall insulation
  • Bottom insulation

Advantages: Wall and bottom insulation reduce heat loss from the water vessel and are particularly useful for frequent use, exposed sites and electric temperature holding.

SPA

  • Air bubble massage system
  • Hydro massage system
  • Sand filtration system with big wooden cover box
  • 2 LED
  • 4 LED (Recommended for 180 – 220 cm models)

Advantages: Air massage gives a gentle whole-tub effect, hydromassage provides firmer targeted jets, filtration supports retained-water use and LEDs improve evening visibility and atmosphere.

Smart SPA equipment add-ons (WiFi signal required)

  • Smart app – voice controlled system kit for air massage
  • Smart app – voice controlled system kit for water massage system
  • Smart app – voice controlled system kit for sand filter
  • Smart app – voice controlled system kit for electric heater (enables scheduled control, ON/OFF)

Advantages: App control can schedule electric support and make filtration, air massage or hydromassage easier to prepare before a planned soak, with separate control applied only to the systems selected.

Inside color

  • White (RAL 9010)
  • Black (RAL 9005)
  • Blue (RAL 5012)
  • Light Grey (RAL 7032)
  • Dark Grey (RAL 7011)

Advantages: Liner colour lets the visible bathing shell coordinate with the garden and can make the water appear lighter, deeper or more neutral without changing the tub geometry.

Metal parts

  • Ash shovel and rake
  • Metal fence on the chimney (burn protection)
  • Stainless steel lid on the heater (only for inside stove)

Advantages: A chimney guard reduces accidental contact risk, a heater lid controls access around the firebox, and dedicated metal tools make ash handling and routine stove care more orderly.

Water release type

  • External water tap
  • External water tap + Quick adapter for garden hose set (12.5mm & 15mm)

Advantages: An external tap gives better control over discharge, while the quick hose adaptor helps route water away from foundations, neighbours and soft landscaping.

Heating ranges from manageable to substantial across the four sizes

A single time cannot cover 1,800–3,400 litres and heater outputs from 6 to 35 kW. TimberIN’s wood-fired manual gives broad 2–3 hour warm-season and 4–6 hour cold-season context, while a 6 kW electric heater on 2,280 litres adds only about 2.3°C per hour before losses. Closed benches, insulation and a cover reduce the load; wind and cold feed water increase it. Choose heater output from the confirmed volume and desired operating routine, then have the electrical or flue design approved before manufacture.

Use the flexibility to solve the site, not to collect options

Start with normal occupancy, the measured access route and the maximum footprint available after allowing for steps, heater and maintenance. Then select a heating routine: wood for a hands-on heat-up cycle, electric support for scheduled holding, or a hybrid approach where both services are practical. Plan filtration and water care around frequency of use, especially at rentals. The base must support the full water load, and pipework, controls and drain points should remain accessible rather than being permanently hidden by decking.

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 Polypropylene Hot Tub – TimberIN Nordic Flex™ (160–220 cm, Configurable)

What inner diameter choices are shown for Polypropylene Hot Tub – TimberIN Nordic Flex™ (160–220 cm, Configurable)?

Inner diameter choices currently shown are 1600 mm; 1800 mm; 2000 mm; 2200 mm. Availability and valid combinations are controlled by the live configurator and confirmed in the final written order.

Does the displayed price include every option for Polypropylene Hot Tub – TimberIN Nordic Flex™ (160–220 cm, Configurable)?

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 Polypropylene Hot Tub – TimberIN Nordic Flex™ (160–220 cm, Configurable)?

Choose the normal occupancy and shell size first; nominal capacity is not a comfort guarantee for every body size. Select heater position and fuel after checking usable seating, firebox access, chimney route and any electrical supply. Confirm delivery access, a level load-bearing base, safe filling and drainage, and the intended winter operating routine. Final dimensions, included equipment and site responsibilities should be confirmed before production or dispatch.

Dear TimberIN Team, Many thanks to the whole team at TimberIN. We are really pleased with our wood burning hot tub. The delivery was on time and efficient, although I would stress to people taking delivery to ensure you have lots of friends to help move it and/or equipment on hand if it needs to go over a fence. We were 9 people in the end who manoeuvred the hot tub into position through a very tight gate hole and it was no easy job. We had the tub up and running within hours and have been surprised how often we’re using it even after the initial honeymoon period. The quality and craftsmanship are great and unlike other more conventional ‘plastic’ hot tubs we saw it really does look great. So far all members and ages of the family have enjoyed it, from our nephews splashing around over Christmas, to Grandma relaxing under the stars with a drink on hand in the ‘bar’. We’re looking forward to many years of fun use to come! Tom and Family

    We’re looking forward to many years of fun use to come!
