Leil Round Cube Relax Outdoor Wooden Sauna Cabin 6-Person
Leil Round Cube Relax Outdoor Sauna 6 Person
The Leil Round Cube Relax Outdoor Sauna is designed for up to six people and features a U-shaped bench layout that provides space for both sitting and reclining. Its distinctive curved design, full circular arches, and large glass front create a spacious outdoor sauna with a modern architectural style.
Handcrafted in Estonia and recognized with the Red Dot Design Award 2024, the Round Cube Relax combines a 1.57" (40 mm) ThermoWood structure with a premium black shingle roof. The three-level aspen bench layout provides flexible seating and reclining space for group sauna sessions.
The front wall features double tempered glass and is available in mirror, bronze, or black finishes. An optional handcrafted Estonian juniper back wall is also available for a natural wood finish and aromatic character when heated.
The Round Cube Relax uses an integrated platform layout with the heater positioned inside the sauna platform, so this model is designed for electric heater use only. The sauna heater, controls, and electrical components are purchased separately.
