Choose your package
- No heater: the cabin only. You will need a suitable heater, sauna stones and controls, bought separately.
- Narvi NM Domestic 6kW Black + stones: the cabin with a Narvi NM 6 kW electric heater and sauna stones.
- HUUM Core Wall 6kW Black + HUUM UKU WiFi Glass + stones: the cabin with a HUUM Core wall-mounted 6 kW electric heater, the HUUM UKU WiFi Glass controller and sauna stones.
Electric heaters must be hard-wired by a qualified electrician. Electrical work and installation are not included in any package.
Why choose this cube sauna?
- Black thermally modified wood: thermal modification improves the timber’s resistance to decay and warping and gives it a darker, richer colour.
- Space-efficient design: the square shape maximises the interior space within a compact footprint.
- Made for indoor use: with an integrated ventilation valve. Bitumen roof shingles are also included.

Before you order
Floor: the cube needs a level, solid floor that can carry its weight (about 450 kg) plus the people using it.
Room size and ceiling height: the cube is 221 cm tall, so the room needs extra space around and above it for assembly and ventilation. The clearances required are set out in the manufacturer’s installation manual, which we can send you before you order.
Ventilation: the room must be adequately ventilated, either naturally (a window or air vent) or by mechanical extraction, to supply fresh air and remove moisture during use.
Electrical supply: the heater must be connected by a qualified electrician to a suitable dedicated supply, as specified in the heater manufacturer’s installation manual.
Assembly: supplied flat-packed for self-assembly, with hardware and instructions.
Delivery: supplied in a single box of about 209 × 111 × 78 cm (L × W × H) and delivered by freight. Please contact us before ordering so that we can confirm the delivery arrangements, and check that the box can be carried to the room where the sauna will be assembled.
Warranty
The cabin is covered by the manufacturer’s warranty; please contact us for the terms before you order. Heaters and controllers carry their own manufacturers’ warranties.
Why thermally modified wood?
The timber is heated to around 200°C, which permanently changes its cell structure. This makes it more stable and more resistant to decay, and gives it a naturally darker colour that suits contemporary interiors.
Building Regulations
Indoor sauna installations should comply with Building Regulations, particularly for ventilation, electrical safety and structural loading. Please consult a qualified professional to make sure your installation meets the requirements for your property.
