Leil Celto Outdoor Sauna
Celto is Leil's most approachable outdoor sauna: solid 60 mm cross-laminated timber (CLT) panels for walls, ceiling and floor, generous bronze-tempered glazing that fills the room with light, and an EPDM roof on an impregnated base frame. Two people can assemble it in about four to six hours.
Celto S seats two and fits small yards and terraces; Celto M has a wider interior for three. Both have two-level aspen benches with a wide backrest, four ventilation openings and an optional LED strip behind the backrest. Electric heater; heater not included.
