How Saunakivi works

  • Every specification comes from the maker's own website or manual, and links to it.
  • A figure we cannot find on the maker's own pages is left out, never estimated.
  • We compare what makers publish. We have not tested these products, and we make no claim about what a sauna, a cold plunge or a steam shower does for your body.
