The Harmone 2-Person Leil® Celto S Outdoor Sauna combines traditional Nordic craftsmanship with innovative cross-laminated timber (CLT) construction to create a strong, thermally efficient sauna for indoor or outdoor spaces. Designed for up to two people, its compact footprint makes it an excellent option where space is limited without compromising comfort or build quality.
Featuring solid 60 mm Nordic Spruce CLT panels, premium knotless aspen benches and backrest, tempered glass windows and door, and a 6.8kW Harvia Cilindro heater, the Celto S delivers a thoughtfully engineered sauna experience. Its prefabricated modular construction also allows for straightforward assembly and the flexibility to carefully disassemble and relocate the sauna if required.
At the heart of the Celto S is its cross-laminated timber construction. Layers of solid Nordic Spruce are bonded at alternating angles to create structurally strong and stable 60 mm panels. The dense timber walls help the sauna heat efficiently and retain warmth while creating a durable structure suitable for demanding sauna environments.
The precision-engineered panel system arrives flat-packed and is designed for straightforward assembly using basic tools. Once assembled and connected by a licensed electrician, the included 6.8kW Harvia Cilindro heater and 80 kg of traditional olivine diabase stones provide the heating system for the sauna.
Because of its modular construction, the Celto S can also be carefully disassembled and reassembled when needed, offering greater flexibility for future relocations, renovations, or changes to your space.
