Saunum AirCube One – A Stylish, Modern Sauna for Any Garden

The Saunum AirCube One is a beautifully designed outdoor sauna that brings comfort, warmth, and relaxation straight to your garden. With its clean, modern shape and high-quality build, it fits perfectly beside a patio, pool, or quiet corner of your outdoor space. Strong materials and expert craftsmanship make it both long-lasting and luxurious, giving you a peaceful place to unwind after a busy day—or a great spot to enjoy with family and friends.

This sauna is practical, elegant, and designed to be the standout feature of any garden.

Customise It To Match Your Style

Exterior Colours – Black, Anthracite, or Light Grey

Choose a colour that suits your home and garden. All three options keep the AirCube One looking sleek and modern.

Glass Choices – Clear, Bronze, or Grey

Pick the level of light and privacy you prefer:

  • Clear for bright openness
  • Bronze for a warm, gentle tint
  • Grey for a modern look with extra privacy

Interior Woods – Alder or Thermo-Aspen

Alder wood comes as standard, offering a warm and comfortable feel.
Upgrade to Thermo-Aspen for a tougher, premium wood that handles heat incredibly well and keeps its shape for years.

Benches – I-Shaped or L-Shaped, Alder or Thermo-Aspen

Choose a classic straight bench or a more spacious L-shaped layout. Both can be made in either Alder or Thermo-Aspen, depending on the look and durability you prefer.

Lighting, Sound & Atmosphere

The AirCube One includes indoor and outdoor LED lighting, helping you create the perfect mood whether it’s daytime or evening. Optional dimmable lights add a soft, cosy glow. You can also add Bluetooth speakers to enjoy music or relaxing sounds during your sauna session.

Built with Smart Features

Every detail is designed for comfort and ease—from the self-closing door with a solid oak and steel handle, to the insulated walls that keep heat inside efficiently. It’s simple to maintain, dependable, and built to last.

Made for Your Personal Wellness

The Saunum AirCube One is fully customisable so you can create a sauna that suits your taste and your outdoor space perfectly. Choose your colours, glass, wood type, and bench style to build the sauna that feels just right for you.

The Saunum Sauna Experience

How It Works

Saunum is a world leader in sauna innovation, renowned for its patented air-blending technology that creates a perfectly balanced thermal environment. Because Saunum units are precision-engineered and arrive as significant, pre-assembled structures, we follow a rigorous professional process to ensure your investment is handled with the highest level of care.

1. Place Your Order & Site Assessment

We invite you to schedule a personalised consultation with our specialist team to discuss your project in detail. We recognise that a wellness installation of this calibre is a significant investment, and we are dedicated to providing the expert guidance and transparency you need to move forward with complete confidence.

During this stage, we review your selected model—from the Leil to the Primary series—and perform an initial assessment of your property to ensure a seamless logistical path.

2. Bespoke Production

Once your specifications are finalised, your sauna enters the production phase.

  • Craftsmanship: Every Saunum sauna is built to order, ensuring that the timber work and internal air-blending systems are integrated to factory standards.
  • Lead Times: Due to the bespoke nature and high level of customisation, the production lead time is 8–10 weeks.
  • Total Timeline: Including international transit and logistics coordination, you should expect a 10–12 week window from order to arrival.

3. Delivery & Professional Logistics

While we offer complimentary delivery to Mainland UK, it is important to understand the distinction regarding "Last Mile" logistics.

  • Pre-Assembled Nature: Because Saunum saunas are delivered fully built, they require specialist handling.
  • Logistics Audit: We consult with our specialist delivery partners prior to production to verify access.
  • Last Mile Requirements: The final stage of delivery (from the kerbside to your specific location) often requires specialised equipment such as a HIAB or crane. As access requirements vary significantly from property to property, this "last mile" service is quoted and invoiced separately based on your specific site needs.

4. Preparation Checklist (Pre-Delivery)

A successful installation relies on two critical pillars of preparation:

  • The Foundation: You must provide a solid, level foundation. This base must be engineered to support the combined weight of the structure and its maximum occupancy.

    • Example: If your sauna weighs 1,600kg and accommodates 4 people, your base should be rated to support 2,000kg – 2,200kg.

  • Electrical Infrastructure: Electrical installation is the customer’s responsibility. We strongly recommend consulting a qualified electrician before placing your order.

    • Resources: We will provide the specific Saunum wiring and heater manuals in advance so your electrician can ensure your property’s power supply is prepared for the specific load.

5. Delivery & Inspection

On your scheduled delivery day, your sauna arrives in its final, pre-assembled form.

  • Specialist Equipment: Our team will utilise the equipment identified during your site assessment (e.g., crane or heavy-duty forklift) to navigate your property's specific access requirements.
  • Once the unit is positioned and unpacked, please inspect all components, including the glass facade and internal air-blending heater. To maintain your warranty eligibility, any discrepancies must be reported to our support team within 24 hours.

6. Installation: The Plug-and-Play Advantage

One of the primary benefits of a Saunum sauna is the "Plug-and-Play" design. Because the unit is pre-assembled, no on-site sauna build construction is required.

  • Final Connection: Installation consists primarily of your certified electrician connecting the unit to your pre-prepared power supply.

7. Warranty Validation & Handover

To validate your manufacturer’s warranty and protect the integrity of the Nordic timber:

  • Wood Treatment: You must immediately treat the interior and exterior timber with a high-quality, suitable breathable wood oil. This is a mandatory step to protect against moisture and ensure long-term durability.
  • Mechanical Check: Verify that doors, windows, and ventilation slats operate precisely.
  • System Commissioning: Once the electrical connection is certified, run a full test cycle of the Saunum air-blending heater and any integrated LED systems to experience the unique Saunum climate.

8. Enjoy Your Sauna & Aftercare

Your Saunum is designed to provide a lifetime of superior wellness.

  • Maintenance: Periodically inspect the wood finish and electrical components. Proper maintenance ensures the patented air-blending system continues to perform at its peak for decades.
  • Ongoing Support: As your dedicated reseller, we provide long-term assistance. Contact our team at any time for maintenance advice, replacement parts, or technical support.
Heater Information +

The Saunum AirCube One Outdoor Sauna is compatible with two advanced heating systems:

  • Saunum Experience Heater: A flexible solution with adjustable height, efficient air mixing, and smart control compatibility—ideal for everyday use.
  • Saunum Spa Session Heater: A premium wall-mounted heater with concealed ducting and dual-level stone baskets, designed for longer-lasting heat and refined steam control.

Both options integrate with Saunum Leil smart controls, including mobile and Wi-Fi functionality, giving you full control over temperature, timing, and sauna modes.

Delivery & Installation +

Delivery and Unloading Guide

All Saunum products are custom-crafted to order in Estonia, the historic home of the traditional sauna. While we are pleased to offer complimentary delivery directly to your doorstep, please be advised that unloading and final positioning of the sauna are the customer's responsibility.
Because all Saunum saunas arrive fully assembled, they cannot be offloaded by hand. We highly recommend consulting our Installation Guide prior to delivery to ensure your site is adequately prepared.

Offloading Options

Depending on your property's accessibility, you will need to arrange one of the following specialised offloading methods:

  • Forklift: This is the most cost-effective solution, provided your property has adequate space and suitable terrain to transport the sauna from the delivery truck to its final location.
  • HIAB (Lorry Loader): A highly practical and affordable option if the sauna needs to be lifted over roadside boundaries, such as fences or low walls.
  • Crane: This service is necessary for more complex deliveries where the sauna's final destination is situated far from the road and is inaccessible to a forklift.

We can arrange the unloading for you, for an additional fee.

Foundation and Site Preparation Requirements

Proper site preparation is essential to ensure the longevity and structural integrity of your sauna. Please ensure your chosen location meets the following criteria prior to delivery:

  • Level and Stable Base: The foundation must be completely level and stable to safely support the weight of the sauna.
  • Full Beam Support: Every base beam beneath the sauna requires continuous, solid support underneath it.
  • Minimum Elevation: To ensure proper airflow and prevent moisture damage, the sauna must be elevated at least 75 mm above the surrounding ground. Please note that this elevation rule applies even if you are placing the sauna on a hardscape surface, such as a terrace or pavement.
  • Our Recommendations for a Perfect Base: We highly recommend placing the sauna on concrete blocks or concrete strip foundations set over compressed gravel. If you are installing over natural ground, laying a geotextile weed membrane underneath the sauna will effectively prevent grass and weeds from growing into the structure.

Need Assistance? If you are uncertain about site preparation or which offloading solution is most appropriate for your property, please contact us. Our team is happy to provide personalised advice and help you determine the best approach for a seamless delivery.

Return & Refund Policy +

Returns and Refunds Policy for Made-to-Order Saunas

We take pride in delivering high-quality, made-to-order saunas designed to meet your unique specifications. Because each sauna is individually crafted, our returns and refund policy reflects the bespoke nature of these products.

Why Returns Are Limited for Made-to-Order Saunas

Each sauna is custom-built according to specific customer requirements. As these items cannot be resold or restocked, we are unable to accept returns or offer refunds once the production process has begun.

Please review all details of your order carefully before confirming, including dimensions, features, and finishes.

  • Our Policy in Detail: Customisation Acknowledgement: By placing an order, you acknowledge that your sauna is a bespoke product created to your specifications.
  • Non-Returnable Items: Once production has commenced, cancellations, returns, or refunds are not permitted unless the product arrives defective or damaged.
  • Damaged or Faulty Products: If your sauna arrives with visible damage or a manufacturing defect, please notify us within 48 hours of delivery.

We will assess the issue and may provide a repair, replacement, or refund, depending on the circumstances.

Order Review

We strongly recommend verifying all measurements and customisation details before confirming your order.

  • Right to Cancel (Before Fabrication): You may cancel your order before fabrication begins, subject to an administrative fee.
  • Relevant Consumer Laws: This policy is designed in accordance with UK consumer protection laws, including the Consumer Rights Act 2015. Products must be of satisfactory quality, fit for their intended purpose, and accurately described. If your sauna fails to meet these standards, we will take appropriate action to resolve the issue.
  • Consumer Contracts (Information, Cancellation, and Additional Charges) Regulations 2013: Bespoke and made-to-order items are exempt from the standard 14-day cancellation period for online purchases. However, your rights remain protected if the product is faulty or does not conform to the agreed specifications.
