Saunum AirCube Terrace: Sauna and Outdoor Living, In One. Built to Order

The AirCube Terrace brings something the others don't — an integrated outdoor terrace that extends the experience beyond the cabin itself. Heat, fresh air, and open sky, all in one considered build. Crafted to your specification and designed to become the heart of your outdoor space, this is wellness living at its most complete.

More Than a Sauna

The AirCube Terrace blurs the line between sauna and home spa. Step out of the heat and straight onto your own private terrace — sheltered, connected, and entirely yours. It's a setup that turns a single session into a full experience, and a garden into something you never want to leave.

Built to Last, Inside and Out

The exterior is clad in planed thermally modified pine, finished in black as standard and built to hold its own through every season. Inside, STS Alder lines the walls, bench seating, backrests, bench skirts, and wooden floor matting — rich, smooth, and a genuine pleasure to spend time around. Double-glazed tempered glass floods the interior with natural light, while the self-closing door with lock seals in the heat and the quiet whenever you need both.

Every Detail Considered

Dual LED strip lighting behind the backrests and beneath both the upper and lower benches creates a layered, atmospheric glow inside the cabin. Outdoor LED lights, a rain gutter, ventilation, and a full electrical box are all included as standard — everything thought through before your build even begins.

Made to Order, Made for You

The AirCube Terrace is a custom build, crafted once your choices are made. The base build comes finished in black with clear glass and STS Alder throughout. From there, the decisions are yours — upgrade the exterior to anthracite, light grey, or a bespoke colour. Choose grey or bronze glass. Switch to thermo-aspen for the interior, benches, or floor. Upgrade to an L-shaped bench. Add an extra window, dimmable lighting, or a Saunum Pro Experience heater. Your space, your way.

Why We Love Saunum Saunas

Our appreciation for Saunum saunas started in Tallinn, Estonia, when we went to visit the people behind the product. Here, sauna has been a way of life for centuries. It’s where people reset after a long day, strengthen their bodies, and find stillness in a fast-moving world. Sauna is part of the national identity. The result is an experience that's deeper, reflecting Estonia’s uncompromising respect for craftsmanship, authenticity, and wellbeing. Want some guidance on your sauna? Give us a call, we'd be happy to talk through your plans and help you find the perfect option.

FAQS

Where can I find an installation guide?

Installation Guide Technical Overview

Which control unit do I choose?

Display & Controls Outside Sauna — Simple and practical. Set everything up before you get in and let the sauna do its thing.

 

Display Outside, Button Inside Sauna — The most popular choice. Trigger a fresh splash onto the stones from the bench without breaking your session.

 

Display & Controls Outside Sauna, WiFi — Pre-heat remotely so your sauna is ready the moment you walk in.

 

Display Outside, Button Inside Sauna, WiFi — The best of everything. Control from your phone and splash on demand from the bench.

How do I choose between Alpine and Thermowood?

Both Alpine and Thermowood are premium Nordic timber options. Alpine cladding offers a lighter, natural timber tone that looks more traditional. Left untreated, it will gradually soften to a silvery patina. Thermowood has a deeper brown tone from the offset. It contrast, undergoes a high-temperature thermal modification process that enhances dimensional stability and improves resistance to moisture and movement. Over time, it ages evenly and typically requires less intervention to maintain its appearance.

What's the vapour barrier and wind barrier for?

Saunum saunas are built using a layered wall system that includes both a vapour barrier and a wind barrier. They're not visible features, but are defining difference in construction quality. This approach ensures heat is retained more efficiently, moisture is managed correctly within the structure, and the cabin performs consistently in outdoor conditions. Lower-cost outdoor saunas often omit these layers to reduce manufacturing costs, which can compromise insulation performance and long-term structural stability. 

It says a Protan SE 1.2mm PVC roof covering is included - what is that? 

It offers a superior level of weather resistance. The membrane remains stable through temperature extremes, resists UV exposure, and provides long-term waterproof protection without degrading. Usually, lower-cost outdoor saunas rely on basic felt or lightweight coverings. Those shaped by Nordic climate and tradition signal a level of reliability that's difficult to find elsewhere. In Estonia, sauna is not a trend — it is part of everyday life. Structures are built to endure long winters, shifting temperatures, and years of use. That mindset influences every material choice. This is not just a roof covering. It’s a detail rooted in Estonian building culture.

Why are sauna cabins and sauna heaters sold separately?

Saunas and heaters are sold separately because no two sauna spaces or users are quite the same. Keeping them separate lets you choose the right heater size, output, and features for your specific room and how you like to sauna, rather than settling for a generic, bundled option. It also gives you flexibility in the future, whether you want to upgrade the heater or refine the experience without changing the whole sauna.

What are the 5 sauna modes and how do they differ?

These are five, integrated and distinct climate choices within one intelligently engineered space. You can choose a traditional high-heat Nordic sauna, a more humid steam-rich session, a lower-temperature relaxing mode, or enhance the environment with salt ions or aromatherapy —whichever suits your preference for the session.

Why are these saunas delivered pre-assembled?

Saunum cabins are delivered pre-assembled so that every structural and thermal detail is completed in a controlled environment. This ensures the insulation, vapour barriers, glazing, and exterior finishes are installed with precision before the cabin reaches your property. The result is consistent build quality and a cleaner, more refined finish. For you, this means a simpler installation process and confidence that the sauna has been constructed exactly as intended.

Can you help me install the sauna?

Yes, absolutely. Because the sauna is delivered as a pre-built structure, it cannot be offloaded manually. We can arrange unloading and positioning on your behalf at an additional cost, managing the process from start to finish. The appropriate lifting solution will depend on your site access and final installation position. In some cases, mechanical lifting equipment can move the cabin directly into place. Where access is more restricted, or the sauna needs to be positioned over a boundary or deeper into the property, a lorry-mounted crane or mobile crane may be required. If you would prefer us to coordinate this, simply contact us for a tailored quotation. We are also happy to review site photos or plans in advance to help determine the most suitable approach. Please note, you will need a qualified electrician to connect the sauna to your power supply.

Should I buy the protective OSB box?

These are purpose built to shield the exterior cladding, glazing, and finishes during delivery. This reduces the risk of cosmetic damage and ensures the sauna arrives in the same condition it left the workshop. It’s a practical detail that protects both your product and investment.

The 5 Sauna Modes

Classic Nordic Sauna 

(60–100 °C)

Hot and dry! This is the traditional Nordic sauna experience, with higher temperatures and drier air. It feels intensely warm and invigorating, helping to relax muscles, improve circulation, and create the authentic effect cherished for centuries. 

Humid, Steam Rich Sauna

(60–100 °C)

Soft, soothing, and steamy! This mode uses more humidity and lower temperatures, so it feels gentler and easier to breathe in. The moist heat is very relaxing, helps prevent the air from feeling too dry, and is ideal if you prefer a steam-room-like experience. 

Mild, Relaxing Sauna

(40–55 °C)

Gentle warmth. This mode uses more humidity and lower temperatures, so it feels gentler and easier to breathe in. The moist heat is very relaxing, helps prevent the air from feeling too dry, and is ideal if you prefer a steam-room-like experience. 

Salt-Ion Sauna

(40–100 °C)

Wellness focussed air quality. Adding salt spheres releases salt ions into the air. It feels similar to a regular sauna but with cleaner, fresher air. Many people find it helps create a more refreshing atmosphere and supports easier breathing and overall wellbeing. 

Aromatherapy Sauna

(40–55 °C)

Gentle warmth. This mode uses more humidity and lower temperatures, so it feels gentler and easier to breathe in. The moist heat is very relaxing, helps prevent the air from feeling too dry, and is ideal if you prefer a steam-room-like experience.
