Saunas can be assembled by any 2 adults, even if they have no prior sauna building experience. Clearlight® Premier saunas take about 1 hour to assemble and Clearlight® Sanctuary saunas take about 2 hours to assemble. Some people opt to have their saunas assembled by a handyman with an assistant. No tools are required for the sauna assembly, with the exception of a Philips screwdriver. All of the saunas come with the heaters, electrical, sound system and lights pre-installed in the sauna walls and roof. For this reason, the saunas go together easily and they can also be disassembled, moved and reassembled – all with equal ease.
