About this Sauna
As the smallest member of Leil’s Round Cube family, the Round Cube Mini is designed to deliver a genuinely premium sauna experience without dominating your garden.
Its distinctive curved corners soften the contemporary cabin shape, while configurable glazing and natural Thermowood give it the architectural quality that sets the Round Cube collection apart.
Inside, multi-level Aspen seating provides comfortable space for 4–5 people, complemented by backrests, footrests and dimmable LED lighting. An optional Juniper feature wall can introduce another layer of natural texture and aroma to the interior.
With two different depths available, it’s also easy to choose a footprint that suits your available space. For customers who love the Round Cube aesthetic but don’t require the scale of the Single, Double or Relax, the Mini is arguably the sweet spot.
