Review the supplied manufacturer documents before electrical work, installation, assembly, or operation.
Is the Cal Saunas Solara 4 Right for Your Home?
The Solara 4 is best suited to homeowners who want a larger residential infrared sauna with room for up to four users while still keeping the cabin manageable for a dedicated indoor wellness space.
Its 10 carbon infrared heaters, Canadian Hemlock construction, integrated digital controls, RGB and LED lighting, glass door, and built-in audio make it a feature-rich option for households that value both capacity and convenience.
