The story of Rexener hot tubs began with one man’s dream. Thinking, planning, manufactured parts, trial and error. This is how the first handmade hot tub was made, from Finnish raw materials, at Sarininkulma in Rekijoki.
At first, the entrepreneur only intended to earn a small amount of additional income. However, once the orders started pouring in, there wasn’t even time to sleep. By June 2020, nearly 1,400 hot tubs had already been sold all over Finland. Demand for such an excellent product was high, and now the hot tubs are being developed by a top international team.
The premium handmade fibreglass hot tub found its niche in a market saturated with massproduced products. Its uncompromising quality and level of finish said it all. Every hot tub manufactured and sold convinced new customers at an increasing pace.
At the same time as Sarininkulma was hard at work manufacturing hot tubs in Sipoo, Grels “Celle” Ström had the idea to use Airrex hall heaters’ technology to warm up hot tubs. Rexener Bioheater was born. The two men’s paths eventually converged, and now their innovations are reflected in Rexener’s hot tubs.
Even with all the Finnish “sisu” in play, making more than 300 hot tubs in one year began to take its toll on the one-man workshop. The time had come to take the next step towards conquering the world. With Rex Nordic, the one-man workshop became a Nordic team of nearly 40 people, who are now building the story of the best hot tubs on the market for future generations.
The colours and material choices of Rexener hot tubs have been inspired by the northern nature. The frame and panelling are made from genuine Finnish wood. The colours of our hot tubs come from the building blocks of the wintry northern dreamscape – the white snow and the black granite stone of the north, Gabro.

REXENER Polar 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.
Unique and spacious
– seats up to 8 people
No need for an electrician or expensive electrical connection/ cabling. Works with 10A lighting current.
The filter and UV light ensure that the water stays clean for longer. The Gelcoat surface is easy to keep clean. Thanks to the integrated chemical dispenser, the use of chemicals is simple and easy.
If there’s a problem, we’ll visit your home to service your hot tub.
The first heating only takes around 4 litres of fuel.
Automatic thermostat control (0–40°C). The timer enables you to easily program how often the circulating water pump and heater run. The energy consumption will decrease by up to two-thirds.
Heats from cold to ready to use (7–37°C) in around two hours (including one hour to fill the pool).
Quick and easy draining, extremely well-insulated.
NEW! A SMALLER, SEPARATE HEATER UNIT AND BUILT-IN TECHNOLOGY ALLOW FOR MORE FLEXIBLE INSTALLATION AND EASIER MAINTENANCE.
A distance of up to 10 metres between the pool and the heater offers new installation opportunities. You can place the heater further from the pool for an aesthetic effect, and you can embed the pool in the terrace/patio.
You can install the heater unit up to 10 metres from the pool. Please note, however, that the best energy efficiency is achieved when the heater unit is attached to the pool/tub. If you install the heater unit further away, we recommend that you insulate the water hoses well. 0-10 m
