Description
The URSA® Black Outdoor Sauna is Finnmark’s modular garden sauna for 3–4 people, built from 55 mm cross-laminated timber and clad in black stained thermo pine, with the same thermally treated, knot-free interior as the natural version. A full glass front with a glass door offers unobstructed views and plenty of natural light, while a roof overhang at the side gives practical space to hang towels. Inside, two-tiered thermo aspen and thermo alder benches run along the back wall, with warm-white LED strips behind the backrest. The sauna arrives flat-packed with Moffett delivery to most mainland UK postcodes included, and is sold as the cabin only, with an electric heater package comprising the HUUM HIVE Mini 10.5 kW heater, the UKU Wi-Fi controller in glass black and stones, or with a wood-burning package built around the HUUM HIVE Flow Mini with a through-the-ceiling flue kit and stones; a personalised installation service can be quoted on request. The natural-finish URSA Outdoor Sauna is listed separately.

Assembly
URSA arrives flat-packed for straightforward assembly. A personalised installation service is available on request; quotes depend on location and access.
Foundations
The cabin can be installed on a concrete foundation, concrete blocks or ground screws. Leave at least 300 mm clearance between the sauna’s footprint and any nearby wall or fence.
Heater options
The cabin is sold without a heater, with an electric package comprising the HUUM HIVE Mini 10.5 kW heater, the UKU Wi-Fi controller with a glass black panel and sauna stones, or with a wood-burning package built around the HUUM HIVE Flow Mini. The wood-burning kit includes the HIVE Flow Mini, a through-the-ceiling flue kit, protective bedding and spill-guard, and a sufficient quantity of stones.
Timber
The structure is 55 mm mixed wood cross-laminated timber, whose thermal mass absorbs heat gradually, distributes it evenly through the room and minimises heat loss, so the sauna heats at a consistent rate without sudden temperature spikes. The interior cladding and benches are thermally treated, knot-free thermo aspen and thermo alder, and the benches and backrests are pre-treated with Tikkurila Supi Saunavaha.
Care
Protect the benches with seat covers or towels, clean spills promptly and avoid paints and varnishes, re-treating the wood with Supi sauna wax after deep cleaning. The door opens outwards for safety, and the air vents should be closed during heavy rain, storms or snow. Full guidance is given in the Operations, Maintenance and Safety manual in the Downloads tab. Seasonal weather conditions may influence the heat-up time of any outdoor sauna.
Brand
