IKI Sauna Heaters

A cube sauna is a modern sauna featuring a clean, square profile that maximises usable space while offering an authentic sauna experience. Unlike traditional cabin-style designs, cube saunas combine contemporary architecture with efficient use of space, making them suitable for gardens, indoor wellness areas, basements, and converted spaces.

Our cube saunas are designed as comfortable two-person saunas, providing enough space for one or two people to enjoy a relaxing sauna session. Their compact footprint makes them ideal for those who want a genuine sauna experience without requiring the space of a larger traditional sauna.

Yes. Our range includes both indoor cube saunas and outdoor cube saunas, allowing you to choose the model best suited to your space. Outdoor models are designed to withstand the changing British climate, while indoor cube saunas are ideal for spare rooms, basements, and dedicated wellness areas.

A thermowood cube sauna is constructed using thermally modified spruce, a specialist timber treated at high temperatures to improve durability and stability. This process helps the wood resist moisture, decay, and warping while enhancing its natural colour and grain.

Most customers can complete the installation of a cube sauna over a weekend. Each sauna arrives as a complete kit with the heater, sauna stones, benches, tempered glass door, roof components, fittings, and instructions required for assembly.

One of the benefits of a thermally modified timber cube sauna is its excellent durability and low maintenance requirements. The heat treatment process improves resistance to moisture and decay, helping the sauna maintain its appearance and performance for many years. For hassle-free upkeep, we also offer a range of sauna cleaning equipment and care products, making it easy to keep your sauna clean and looking its best with minimal effort.

The main difference is where the sauna is designed to be installed. An indoor cube sauna is suited to spaces such as spare rooms or basements, while an outdoor cube sauna is designed specifically for garden installation and year-round exposure to the elements.

Yes. Our range includes a selection of finishes, including the distinctive black cube sauna, which offers a contemporary architectural look and makes a striking addition to modern gardens and outdoor spaces.

A cube sauna offers a more contemporary, architectural design with straight lines and a practical layout, while a barrel sauna has a more traditional curved appearance. The right choice depends on your preferred style, available space, and how you want your sauna to complement its surroundings.
