BigCube Thermowood Sauna 216 × 160 × 216 cm – Outdoor Sauna for Garden & Terrace

A spacious Thermowood outdoor sauna for gardens, terraces and private wellness areas. BigCube is designed for 2–4 people and offers more interior space than Mini Cube while keeping a modern, compact outdoor format.

The BigCube Thermowood Sauna is a modern outdoor sauna designed for private gardens, terraces, patios, holiday homes and wellness corners next to the house. With external dimensions of 216 × 160 × 216 cm, it offers more space and comfort than a small compact sauna, while still remaining suitable for private outdoor use.

Made from high-quality Thermowood with CLT plate construction, BigCube is designed for outdoor conditions and long-term use. Thermowood is heat-treated timber that offers improved dimensional stability and better resistance to moisture compared with untreated wood. The CLT plate structure in the front and back sections adds a solid, modern construction solution.

The front section is made with CLT plate and glass, creating a more open and premium look. The sauna includes a wooden door with a small glass panel, benches and ventilation openings for proper air circulation. The black roof and rounded cube-style design give the sauna a clean, contemporary appearance that fits well with modern houses, garden terraces, weekend homes and private wellness spaces.

BigCube is suitable for 2–4 people, making it a practical choice for families, couples, small groups or rental properties where a more comfortable sauna experience is preferred.

The sauna can be supplied as a flat pack or ordered assembled. The heater is not included in the base price and must be ordered separately. This model can be used with a suitable electric sauna heater or woodburning sauna heater, depending on the selected configuration and installation requirements.
