A sauna heater, or stove, is an electric or wood-burning appliance that heats the air in the sauna cabin and simultaneously heats the sauna stones placed on top of it. Pouring water onto the stones produces a short burst of humidity (löyly), which raises the perceived temperature without changing the actual air temperature. Electric heaters […]

Sauna stones are natural or volcanic rocks placed on the sauna heater’s heating element, where they store heat and release steam (löyly) when water is poured over them. A suitable stone must withstand repeated sharp temperature shocks without cracking or breaking apart, so dense, homogeneous rocks such as olivine, peridotite, or vulcanite are preferred. The […]

The shower zone is a functional part of the wellness area intended for rinsing the body before and after sauna use or bathing in a hot tub. For hygiene and operational reasons, it is separated from the sauna and hot tub by its own floor covering and drainage, capable of withstanding permanent contact with water. […]

Siberian larch is a coniferous species with high density and natural resin content, used outdoors primarily for decking boards under pergolas and around saunas and hot tubs. Slow growth in a cold climate produces a dense, finely structured wood grain with higher mechanical strength than common Central European conifers. High resin content acts as a […]

Spruce wood is a softwood species commonly used in Central and Northern Europe for wall cladding, structural elements and exterior decking on saunas and pergolas. Spruce has a light colour, a straight grain and a lower density, which makes it easier to work and reduces structural weight. In its raw state it has higher thermal […]
