Story of the Rexener hot tubs

The story of the Rexener hot tubs began with one man’s dream. A lot of thinking, planning, parts manufacture, trial and error. This is how the first handmade hot tub was made, from Finnish raw materials, at Sarininkulma in Rekijoki. In the garage of a house by the forest, a happy hot tub maker grinned broadly
Quality first
The premium, handmade fibreglass hot tub found its niche in a market saturated with mass-produced products. Its uncompromising quality and level of finish said it all. Every hot tub manufactured and sold brought new customers at an increasing rate.

TK Kylpytynnyrit changes name to Rexener Hot Tubs

Even with all the Finnish “sisu” in play, 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 developed into a Nordic team of more than 20 people, who are now building the story of the best hot tubs in the market for future generations.

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.
