Wellness Benefits

Twenty minutes in the Kaski at full heat, a cool rinse, and repeat — the classic hot-and-cold cycle that eases sore muscles, quiets the mind and leaves you genuinely relaxed.

Care & Maintenance

Wipe the timber benches with a damp cloth after use and air the cabin with the door open. Treat interior wood periodically with sauna-specific paraffin oil; never varnish or paint the interior. Re-stack the heater stones and check the heater once a season.
