Not every sanctuary needs to announce itself.

Quantum presents the Sauna Hiki Large, a six-person outdoor sauna built for those who prefer their wellness space to feel sheltered, private, and deeply calm. Part of the darker, more considered Hiki line, it offers a quieter architectural presence than glass-front models, wrapping its occupants in a warm Thermowood interior that encourages longer, more meditative sessions.

Constructed with 40mm polyurethane-insulated walls, a 30mm insulated roof, and premium Thermowood cladding throughout, the Hiki Large is engineered for year-round outdoor performance in any climate. Heat-treated aspen benches, a 9kW heater, and a generous 3.13m² interior create a space that is equally suited to a quiet solo ritual or an unhurried evening shared with family and guests.

Key Features:

• Sheltered dark exterior for privacy and calm
• Six-person capacity across 3.13m² interior area
• Premium Thermowood interior with heat-treated aspen benches
• 40mm polyurethane-insulated walls and 30mm insulated roof
