How to choose

Far-infrared alone covers most of the published sauna research and costs less. Full-spectrum adds near and mid wavelengths in the same heaters. Finnmark publishes third-party EMF numbers; that is why these three are the first buy links we put on this page. If you want a kit cabin with that report trail, start at Topture. If you want something built for the room, start a SaunaCloud or Sweaty Yeti quote.

Questions people actually ask

Finnmark kit or a custom cabin?

Kit if you want a published spec and a tracked Topture checkout. Custom if the room is odd-shaped or you want a built cabin, via SaunaCloud or Sweaty Yeti.

Which Finnmark size should I buy?

FD-1 for one person, FD-2 for two, FD-3 if you want extra room. See the FD-1 vs FD-2 vs FD-3 page for power and who should skip.
