Description
The Outdoor Cube Sauna is Finnmark Sauna’s own-design two-person outdoor sauna, manufactured in Estonia from thermally modified spruce and supplied as a flat-packed DIY kit. Its square barrel form keeps the footprint to 1,450 × 1,339 mm at 2,217 mm tall, so it suits smaller gardens, while 40 mm staves, an 8 mm tempered glass door and front walls, and two-tier thermally modified aspen benches make the interior feel far from small. Bitumen roof shingles, aspen floor duckboards, an integrated ventilation valve and two stainless steel frame bands are all included, and most customers complete assembly in a weekend. It is sold without a heater, with a Narvi NM Domestic 6 kW electric heater in black and sauna stones, or with a HUUM CORE Wall 6 kW heater in black with the HUUM UKU Wi-Fi Glass controller, safety railing and stones; either heater needs a dedicated 32 A circuit installed by a qualified electrician (installation not included). A black-exterior version is sold separately as the Outdoor Cube Sauna (2 Person) in Black.

Assembly
The sauna arrives flat-packed as a complete DIY kit with pre-cut parts, fixings and step-by-step instructions. Most customers complete assembly in a weekend with basic tools; the manufacturer recommends two people for the build. The stainless steel frame bands should be re-tightened a few days after assembly as the timber settles.
Foundations
The cabin needs a level base of concrete, paving slabs or crushed stone measuring at least 1,500 × 1,400 mm, free from standing water and with adequate drainage. Leave at least 300 mm between the cabin and any nearby wall or fence. At 2,217 mm tall the sauna falls under permitted development rights in most cases, though we recommend checking with your local planning authority, particularly in conservation areas.
Heater options
The sauna is sold in three configurations: without a heater, with a Narvi NM Domestic 6 kW electric heater in black and sauna stones, or with a HUUM CORE Wall 6 kW heater in black supplied with the HUUM UKU Wi-Fi Glass controller, safety railing and sauna stones. Either 6 kW heater requires a dedicated 32 A circuit installed by a qualified electrician; installation is not included.
Timber
The frame and staves are thermally modified spruce, heated to 200 °C to permanently alter the cellular structure of the timber. The process gives the wood its darker, richer colour and markedly improves resistance to decay and warping, so the sauna keeps its shape and appearance for decades.
Care
Thermally modified timber needs no annual treatment. The exterior ages naturally without fading to grey, and the roof shingles and frame bands need only an occasional check.
Brand
The cube sauna is designed by Finnmark Sauna, a UK sauna specialist based in Durham, and manufactured in Estonia.
Ordering & Delivery
This sauna is built to order with a typical lead time of around 16 weeks. Specialist delivery is required and the kit ships in a single box measuring 2,090 × 1,110 × 780 mm; please ensure there is access to your installation site. The Delivery & Returns tab carries the full policy.
