Rex Nordic


bubbles make for the best baths


Call it what you will: hot tub, whirlpool bath, plunge bath, bathtub, spa pool. Rexener Polar is all these things. Serenity and a simple bathtub design. The bubbles and modern atmosphere of a whirlpool bath. The warm and refreshing water of a hot tub. All this is crowned by LED lighting, which brings out the colour of the refreshing water.

Handmade in Finland, Rexener Polar is a high-quality premium hot tub. Rexener Polar has a much shorter heating time than a traditional wood-fired hot tub or an electric hot tub. A built-in filter, UV lights and pool chemicals ensure the water stays clean for a long time.

Optional pool colours: Gabro Black or Arctic White. Polar is made from Finnish wood and insulated throughout.

Price: 6.990 €

A year round use

The Rexener Polar hot tub includes a PR-200 water heater, so now you can maintain the water temperature on the plus side all year round.

Jet set system

Rexener Polar hot tub has a jet set system with 8 nozzles.


In the quiet hot tub you can get atmospherically close to nature. The heater is very quiet, only 48 dB.

Gabro Black or Artic White

The pool colours reflect the building blocks of the dream-like winter landscape – white snow and the black granite stone of the north – Gabro.

Water that stays clean

The filter and pool chemicals ensure that the water remains clean for a long time.

Energy Saving Kit

Low operating costs of the Rexener Polar hot tub

The Rexener Polar hot tub benefits from low operating costs. Its economical pool has a relatively low water volume of ca. 1,300–1,500 litres. Thanks to its advanced design, the pool still feels spacious.

The Rexener PR200 water heater can heat the water from +7 degrees to +38 degrees in less than two hours. This means the heating cost is as low as 4 euros! When the Rexener PR200 water heater is running, its fuel consumption is 2L/hour. However, its thermostat will turn the heater off when the water reaches the right temperature. When the water temperature falls by 2–4 degrees, the heater will turn itself back on.

Fibreglass – the hygienic choice

Fibreglass is durable, robust and easy to clean. Regular washing and drying can help maintain your hot tub’s hygiene. Fibreglass is an excellent material for Northern weather conditions. It is a long-lasting and durable material. Our fibreglass pools are made in Finland and come with a 5-year warranty.

Quick heating – no smoke

The Rexener Polar hot tub is also ideal for detached housing estates, as the heater does not generate smoke that might disturb your neighbours. The Rexener Bioheater is particularly efficient, which means that using it generates only minimal harmful emissions. What comes out of the chimney is mostly carbon dioxide. The hot tub heats up very quickly compared to a wood fireplace. Heating speed is influenced by the outside temperature, and whether or not the pool is covered.

Arctic luxury – inspired by Northern nature

Rexener hot tubs take their colours from the building materials of the idyllic Northern landspace – white snow and the black granite stone of the North, Gabro. Rexener hot tubs have an outer shell that is made of lichen grey Northern wild spruce. It is treated with tinted wood oil which contains little bit wax. Wood oil reduces cracking, protects against moisture and grime.

Enjoy a calm bath

The pool’s corners have comfortable, slanted backrests, and there’s plenty of foot space in the middle. It is also fairly deep in the midsection, which makes the pool feel very large. The Rexener Polar hot tub has a step that makes it easy to climb in and out of the pool, and can also be a children’s seat when necessary.

Easy-to-use drain mechanism – exclusively in Rexener Polar hot tubs

Our products are in active development and as a result, how easy it is to drain the pool is something we have taken into account. All the water can be drained from the bottom of the pool, without having to drain it by hand. The fireplace side of the pool has a drainage valve from which the water drains. You can also attach a 25 mm hose to better direct the water flow.

Rexener Bioheater – a warm hot tub at the press of a button

No need to chop firewood! Anybody can use the Rexener Bioheater: just press the button, and the heater does the rest. It takes considerably less time to heat the water than when heating with wood. The Rexener Bioheater keeps the water temperature constant. No more water that is too cold or too hot in the pool! Adjust the temperature on your own!

UV-light helps keep the pool water clean

– Water circulates from the pool through the circulation pump to the mass filter, and from there through the UVC device to the Rexener Bioheater heater, from where the warm water returns to the pool.
– Water intakes in the pool have grilles so the biggest debris can’t get into the water circulation system
– The circulation pump is equipped with a pre-filter that catches larger debris.
– Inside the mass filter there is filter fiber, which is also called filter balls. These effectively purify the water and bind small dirt particles, such as skin and other dirt that comes off when bathing in the pool.
– The UVC device has a UV light inside that brightens and purifies the water.
– UV light also prevents the formation of algae and reduces potential pathogens in the water.
– UV light reduces the need for chemical disinfection to a minimum and can also reduce the smell of chlorine, for example
