About Polarholz
Polarholz is a sauna manufacturer with its own production facility in Langenlonsheim (Rhineland-Palatinate). The company produces indoor saunas, garden saunas, saunas for sloped ceilings, infrared cabins and commercial sauna systems for hotels, fitness studios, thermal spas and medical practices. Products are made to measure via a 3D configurator as well as in five standard model series. Wood species used include Swiss stone pine and alder; construction is in solid wood with 45 mm log walls in flush cassette construction, as an element sauna with prefabricated elements that can be clad on the outside, and as a design sauna with large glass surfaces, salt stone and indirect lighting. For the technology, sauna heaters, controls and infrared radiators from the EOS brand are offered and installed. Every cabin is fully assembled and tested once after production before being shipped. Delivery is by freight forwarding, and installation is carried out by the company's own team throughout Germany. Showrooms are located in Langenlonsheim and Wiesbaden.
