Wellness Benefits

A cost-effective route to a permanent, built-in sauna without a full custom project. The Ounas kit supplies every component — cut, matched and ready — so a spare room becomes a genuine Finnish sauna.

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.
