Description
Finnmark’s EDEN® Black Outdoor Sauna is a modular garden sauna for 5–6 people, built from 55 mm cross-laminated timber with a black-stained thermo pine exterior, a black-stained terrace and a knot-free thermo aspen and alder interior. A glass door extending into a side window keeps the room bright and open, an overhang roof offers a sheltered spot to hang towels, and two-tiered, L-shaped benches with pre-installed warm-white LED lighting seat the whole group comfortably. The sauna arrives flat-packed with Moffett delivery included for most mainland UK postcodes and is sold three ways: as the cabin alone, with an electric package built around the Narvi Velvet 10.5 kW heater with the UKU Wi-Fi controller and stones, or with a wood-burning package built around the HUUM Hive Flow with its flue kit and stones; assembly and installation services are quoted on request, and the same cabin is available in a natural finish as the EDEN® Outdoor Sauna.

Assembly
The EDEN® Black is delivered as a flat-packed kit for straightforward assembly, and the door is hung to open outwards for safety. Finnmark offers a full assembly and installation service, quoted individually depending on location and access; contact the customer service team for a personalised quote.
Foundations
The cabin can be installed on a concrete foundation, concrete blocks or ground screws, on a firm and level base. Leave at least 300 mm of clearance between the sauna’s footprint and any nearby wall or fence.
Heater options
The EDEN® Black is sold three ways: as the cabin alone, with an electric package comprising the Narvi Velvet 10.5 kW heater, the UKU Wi-Fi controller with a glass black panel and sauna stones, or with a wood-burning package comprising the HUUM Hive Flow, a through-the-ceiling flue kit, protective bedding, a spill guard and a sufficient quantity of stones. Heater installation must follow the manufacturer’s manual.
Timber
The walls are formed from 55 mm mixed wood cross-laminated timber (CLT), a construction chosen for its thermal mass: the layered structure absorbs heat gradually, distributes it evenly through the room and minimises heat loss, so the sauna comes to temperature at a steady rate without hot spots or cold zones. The interior is clad in thermally treated, knot-free timber, and the benches and backrests arrive pre-treated with Tikkurila Supi Saunavaha; the operations manual recommends re-treating seating surfaces at least annually and inspecting the exterior walls periodically, repainting with a suitable varnish to protect the CLT. Please note that seasonal weather conditions may influence the heat-up time of the heater and the sauna space.
Brand

Warranty

Once an in-stock cabin leaves the warehouse it is usually delivered within 3–8 working days.
