Gravity Cabin Sauna

The Gravity Cabin Sauna is our most substantial offering: a full cabin designed to be the permanent centrepiece of a garden wellness space, garage conversion, or dedicated outbuilding. Where barrel saunas excel in compactness, the Gravity Cabin offers space — genuine room to stretch out, change position, or simply lie flat and let the heat do its work. Constructed from double-wall Canadian hemlock panels with a mineral wool insulation layer between them, the Gravity Cabin achieves excellent thermal retention. The enlarged kiuas — loaded with a deep bed of volcanic stones — heats the 4.2 cubic metre interior to authentic Finnish temperatures of 80°C–100°C within 45 minutes, and holds that temperature efficiently once reached. The layout features a two-tier bench system: the upper bench for those who want intense, enveloping heat close to the ceiling; the lower bench for a gentler experience or for stretching. The changing room anteroom — an integral part of the design — provides a space to undress, cool down between rounds, and store towels and accessories without stepping into the cold. The exterior cladding is treated with a charred-effect finish that performs well against UV and moisture while giving the cabin a considered, architectural presence in a garden. The Gravity Cabin arrives pre-cut and numbered, with all fixings, the kiuas unit, and a full löyly accessory kit included.
