Installation Information

The Helsinki Barrel Sauna kit is designed for easy DIY assembly with no cutting required. All components arrive pre-cut and ready to assemble, typically requiring two adults and basic hand tools. The kit includes barrel cradles for stable ground placement and metal bands for a secure, weatherproof build. It is recommended to install the sauna on a level, solid foundation such as a concrete pad, gravel, or a reinforced deck. Note: The 8KW heater requires a dedicated electrical circuit installed by a certified licensed electrician.

Suggested Usage

For a comfortable sauna session, preheat the sauna using the WiFi app to reach your desired temperature, typically between 170°F–185°F. Use the internal two-tier benches to choose your preferred heat level, then utilize the exterior terrace for 5–10 minute cooling breaks between sessions. Many users incorporate sauna time into their regular relaxation, lifestyle, and at-home wellness routines based on personal preference and comfort level. Always stay well-hydrated before and after each session.
