The RUKU Sauna Factory in Illertissen produces top quality saunas to your specifications. Our claim is construction of the best possible sauna or infrared cabin for your requirements. The crucial difference from other sauna producers is our wood insulation. This is made using fibre materials that pose no risk to health and offers the best quality insulation that lasts for decades - and it comes as standard in all our sauna and infrared cabins.

For our infrared sauna we use a special infrared surface system. Compared to a sauna oven, in the RUKU thermium this permits gentle sweating and ensures the best cabin climate with a high oxygen content. In addition, the RUKU Meditherm steam generator enables you to enjoy a steam or aromatic bath in the same cabin (thermium or sauna).

Your thermium or sauna is individually produced according to your preferences regarding size, equipment and design. Our sauna expert will be happy to provide you with personal advice on all the possibilities relating to our sauna and infrared cabins.
