Indoor infrared saunas

Nine cabins from SunRay Saunas, LuxSauna and Enlighten Saunas — from a plug-in two-seater to a five-person full-spectrum room. Real prices and specs from each brand's site.

Check the electrical requirements before you pick a model: some plug into a standard outlet, others need a dedicated 20A circuit or 240V.
