Saunum AirCube Terrace

A complete outdoor sauna with an integrated terrace

AirCube Terrace extends the cabin beyond the glass with a covered outdoor terrace. It gives you a dry threshold for stepping out, cooling down and leaving towels or sandals close at hand.

The current package is finished in black Thermo-pine outside and Thermo-Aspen inside, with the bench, lighting, Bluetooth sound, glazing, ventilation, rainwater system and protective transport box all included. Choose one of two 9 kW Saunum heater sets and one of two bench layouts.

Up to 5With L-shaped bench

1,500 kgApprox. cabin weight

Saunum AirCube Terrace black outdoor sauna with covered front platform in a woodland setting

Included in the base package

The cabin arrives with the finishing details already specified

The timber interior, lighting, audio, glazing and weather-management systems are part of the standard Terrace package.

Thermo-Aspen throughout

Interior cladding, I-shaped bench and backrest, bench skirt and wooden floor mat are all finished in Thermo-Aspen.

Included

Layered dimmable lighting

Two LED strips sit behind the backrest, with further lighting beneath the upper and lower bench. Outdoor LEDs illuminate the terrace after dark.

Included

Bluetooth sound

Integrated Bluetooth speakers let you play audio without bringing a separate speaker into the sauna room.

Included

Built for the weather

Black Thermo-pine cladding uses hidden fasteners, backed by insulated construction, a UV-resistant roof and a rainwater system.

Included

Clear, insulated glazing

Clear double-glazed glass keeps the terrace and sauna feeling connected and bright without losing heat, and the self-closing lockable door with an oak and stainless-steel handle means there's no hardware to fit after delivery.

Included

Prepared for installation

The electrical box and ventilation connections are already prepared at the factory, so there's less for your electrician to source or connect on-site. The cabin travels assembled inside a protective OSB transport box.

Included

Warm LED lighting behind the AirCube Terrace sauna backrest and beneath the Thermo-Aspen bench

A calmer way to move through the session

Warm timber inside, an integrated terrace outside

The Thermo-Aspen interior gives the room a consistent finish from wall to floor. Soft lighting behind the backrest and beneath the bench adds depth without a harsh overhead glare.

Step through the double-glazed door onto the covered platform between rounds. Whichever heater you choose, Saunum's air-mixing system circulates hot air and cooler floor-level air for a more even climate from head to toe.

Dimmable interior LEDsSet the light level for daytime heat or an evening session.

Bluetooth speakersAudio is built into the cabin package.

Air-mixed sauna climateA more even temperature from head to toe.

Four clear choices

Choose the heater and bench that suit you

The cabin finish is fixed. The customiser contains two heater sets and two Thermo-Aspen bench layouts.

Heater choice

Saunum Experience 9 kW Closed Basket SetIncludes 90 kg of sauna stones and the complete Saunum Leil system: external WiFi touchscreen, internal Leil air-circulation button, temperature and door sensors, and mobile app control.

Heater option

Saunum Spa Session 9 kW SetIncludes 60 kg of sauna stones and the same complete Leil control system. Its lower all-in-one design, directional outlet and heavier-duty construction make this the premium heater choice.

Heater option

Bench choice

I-shaped Thermo-AspenIncluded as standard. Seats three in comfort or up to four at classic sauna closeness.

Included

L-shaped Thermo-AspenAdds a return bench for a more sociable layout. Seats four in comfort or up to five at classic sauna closeness.

Bench upgrade

Both heater sets include WiFi and the complete Leil control system. The internal Leil button adjusts air circulation from inside the sauna; the touchscreen control panel is installed outside.

Experience or Spa Session?

The same Saunum principle, in two different heater designs

Saunum Experience delivers Saunum's core air-mixing effect, three airflow settings, salt-ion use and aroma capability in a tall closed-basket design.

Spa Session is shorter, neater and more heavily built. Its dual-level stone basket and adjustable outlet refine water distribution and let you direct the mixed air.

Choose Experience for the better-value route into Saunum's air-mixed climate, or Spa Session for the premium low-profile installation.

Practical planning

Plan the base, access and electrics before delivery

The cabin travels as a large assembled unit. The site must be ready for mechanical unloading, safe positioning and the final electrical and rainwater connections.

A fully supported base

Prepare a level, stable and well-drained base at least 75 mm above the surrounding ground. Every base beam must be supported beneath the approximately 1,500 kg cabin.

Mechanical unloading

The boxed unit weighs approximately 1,650 kg and cannot be offloaded by hand. Depending on access and final position, you will need a forklift, HIAB or crane.

A dedicated supply

The 9 kW heater requires a dedicated electrical supply. A qualified electrician must confirm the protective devices, cable sizing and final connection for your property.

Final on-site work includes the rainwater system, outdoor lighting connections, heater and controls, supply cable and finishing trims. Use the Request an Installation Quote button above the customiser if you would like Heracles to assess the access, base and commissioning work.

AirCube Terrace in context
