Saunum AirCube Terrace Outdoor Sauna FAQs

Can the Saunum AirCube One be delivered flat-packed and assembled on-site?

No, the Saunum AirCube Terrace is delivered fully assembled to maintain its structural integrity and ensure no parts are damaged during transportation or on-site assembly. Delivering it fully assembled also guarantees that the sauna is of the highest quality, ready for immediate use.

Do I need a crane to position my sauna?

Depending on your location, a crane may be needed to position your sauna. If access allows, a forklift can also be used for placement. Our team will assess your site and provide guidance on the best approach for safe delivery and positioning.

Can you organise the crane if needed?

Yes, we can assist in organising a crane or any other required equipment. However, we often recommend that customers hire a local contractor for cost efficiency. Our team will work closely with you to coordinate the placement, ensuring the process is smooth and stress-free.

Why isn’t the heater included in the price of the sauna?

The heater is sold separately to give you the flexibility to choose a model that best suits your needs and preferences. This approach allows you to select a heater that matches your desired sauna experience, whether it’s a traditional or modern heating option.

What are the benefits of Saunum’s patented air-blending system?

Saunum's patented air-blending system ensures even heat distribution throughout the sauna, eliminating hot and cold spots for maximum comfort. It also incorporates salt ions into the steam, which can improve respiratory health and promote healthier skin. The balanced temperature makes sauna sessions more enjoyable and allows for longer, more effective relaxation.

How do I maintain the Saunum AirCube Terrace Outdoor Sauna?

The Saunum AirCube Terrace is designed with low maintenance in mind. The Thermo-pine exterior is treated to resist weather conditions, and regular cleaning with gentle products is recommended. The LED lighting and glass panels should also be wiped down to keep them in pristine condition. For best results, always follow the care instructions provided.

What warranty does the Saunum AirCube Terrace come with?

The Saunum AirCube Terrace Outdoor Sauna comes with a 2-year warranty, covering defects in materials and workmanship. This ensures peace of mind and supports maintaining your sauna in excellent condition.
