Cube Sauna "Cube Premium" with panoramic front

The workday is over. While others are still sitting in their cars or waiting for rush hour traffic, you are already opening the glass door to your own wellness oasis – just a few steps away from your terrace.

Warm light welcomes you. Through the generous panoramic front, your gaze falls upon your own garden, while the soothing warmth already spreads throughout the room. No travel time, no opening hours, no crowds in packed spa areas.

Many garden owners dream of having their own sauna – but forgo it due to lack of space or because traditional saunas look like heavy, dark blocks that dominate the garden instead of enriching it.

This is precisely where the Cube Sauna "Cube Premium" comes in: On a manageable footprint of just 7.32 m², it combines modern, light-filled design with ample space for up to 4 people. The striking panoramic front transforms the sauna session into a nature experience and makes the sauna an architectural highlight of your garden.

You are not just investing in wellness equipment, but in a permanently available retreat that expands your living space and sustainably increases your quality of life.

This speaks in favor of the Cube Sauna "Cube Premium":

• Impressive panoramic front for a connection with nature: Two generous panoramic windows and a glass door made of 8mm safety glass create a light-flooded atmosphere and allow a view into your garden – wellness with an open, modern feeling of space instead of a cramped cabin atmosphere.
• Elegant design on a compact footprint: With external dimensions of only 3.05m x 2.40m, the Cube Premium blends harmoniously into even smaller gardens and still offers comfortable space for 2 people lying down or 4 people sitting.
• High-quality materials for durability and comfort: back wall and side walls made of weather-resistant thermally modified wood in solid log construction, sauna benches and interior fittings made of skin-friendly, low-aromatic aspen wood – a well-thought-out combination of materials for decades of wellness enjoyment.
• Fully equipped and flexibly configurable: Including LED lighting, ventilation grilles, black bitumen roof shingles and a complete sauna accessory set – available as a kit or fully assembled, with an electric heater or a traditional wood-burning stove according to your personal preferences.

Detailed description of the Cube Sauna "Cube Premium":
Panoramic front – Where wellness meets nature experience

The defining design element of the Cube Premium is its generous panoramic front. Two wide panoramic windows and a fully glazed sauna door made of 8mm thick safety glass open up the view to your garden and create a unique connection between the indoors and outdoors. Unlike traditional saunas with small, high-mounted windows, here you experience a feeling of spaciousness and openness.

This glazing is not only aesthetically pleasing but also functionally sophisticated. The 8mm safety glass withstands the extreme temperature differences between the sauna interior and exterior and ensures excellent thermal insulation. This allows you to enjoy the panoramic view without compromising energy efficiency.

Particularly appealing: Whether you watch the rising sun in the early morning, follow the play of clouds during the day or relax under the starry sky in the evening – the panoramic front makes every sauna session a visual experience and enhances the relaxing effect of the heat.

Modern design meets functional construction

The Cube Premium combines contemporary architecture with time-honored craftsmanship. Its cubic, clean lines blend elegantly into modern garden landscapes and appear as a high-quality extension of your living space – not like an afterthought garden shed.

The construction follows the proven log cabin method: Solid 42mm thick logs made of Nordic thermally modified wood form the side and end walls, while the back wall is made of 28mm thick logs. This construction method ensures excellent stability, optimal heat retention, and a pleasant indoor climate. The individual logs are precisely milled and interlock – the result is a tight-fitting, durable structure.

Stable feet ensure a secure hold on any level surface, while stainless steel tension bands allow for later adjustment and retensioning of the log planks. Wood naturally expands and contracts – these thoughtful details ensure that your sauna remains in perfect shape even after years of use.

Thermally modified wood and aspen wood – the perfect material combination

When selecting materials, Cube Premium relies on an intelligent combination: thermally modified wood for the exterior areas, aspen wood for all contact surfaces in the interior.

Thermally modified wood is produced through the controlled heat treatment of Nordic softwood. This process permanently alters the wood's structure: the material becomes more dimensionally stable, weather-resistant, and significantly more resistant to moisture and fungal attack – ideal for permanent outdoor use. At the same time, the wood acquires its characteristic dark, elegant color. The 42mm thick thermally modified wood logs form a robust, heat-insulating shell that protects your sauna from all weather conditions.

Only aspen wood is used for the interior fittings – and for good reason. Aspen wood has low thermal conductivity, meaning it heats up slowly even at high sauna temperatures. This means you can lean back comfortably without burning yourself on hot wooden surfaces. Furthermore, aspen wood is virtually resin-free and develops hardly any odor, even when heated intensely, allowing your sauna infusions to fully develop their aromatic effect.

All sauna benches, backrests, bench panels, the heater guard, and the floor grate are made from this skin-friendly, high-quality wood. The light, warm color of the aspen wood further enhances the open and inviting atmosphere.

Generous space on a compact footprint

With external dimensions of just 3.05m wide and 2.40m deep, the Cube Premium only occupies 7.32 m² of your garden space – yet offers a surprisingly spacious feel. The intelligent interior design, featuring two sauna benches of different widths, allows for flexible usage options.

The lower sauna bench is 39cm wide and offers comfortable seating, while the upper bench, with a depth of 60cm, invites you to relax and lie down. For social sauna sessions, up to four people can sit comfortably. If you wish to enjoy the more intense heat in the upper zone and stretch out completely, the Cube Premium offers ample space for two people to lie down.

The ceiling height of 2.45m and the generously sized door (1.90m high and 69cm wide) allow for comfortable, upright entry. There's no need to bend down or squeeze through narrow openings – access is comfortable and inviting.

This size makes the Cube Premium the ideal solution for garden owners who do not have large areas available, but still do not want to miss out on an authentic, spacious sauna experience.

Flexible oven options to suit every taste

The Cube Premium lets you choose between different heating methods – according to your personal preferences and the local conditions.

You can equip your sauna with either a modern electric heater or a traditional wood-burning stove. Both options are available as complete sets including sauna stones. For electric heaters, we recommend the Harvia Legend Home XW with 10.8 kW output; for wood-burning, the Harvia Linear Compact 18 with 14.3 kW – including a BImSchV2 kit for low-emission combustion in accordance with current legal requirements.

The electric sauna heater impresses with its ease of use, precise temperature control, and fast heating times – ideal if you want to use your sauna spontaneously. The wood-burning sauna heater, on the other hand, creates an authentic sauna experience with the characteristic scent and crackling of a real fire and requires no electrical connection.

A permanently installed fireproof plate made of natural stone on the back wall ensures maximum safety in both versions. The included aspen wood stove guard prevents accidental contact and completes the well-thought-out safety concept.

Well-designed features for a perfect sauna climate

The quality of the Cube Premium is evident even in the details. An integrated ventilation grille ensures optimal air circulation and guarantees a constant supply of fresh air – a prerequisite for a pleasant, healthy sauna climate without stuffiness.

The LED lighting creates pleasant, glare-free light and contributes to a relaxing atmosphere. LEDs do not generate any significant heat of their own, are long-lasting and energy-efficient – ​​even at the extreme temperatures of a sauna.

The high-quality roof structure is covered with black, hexagonal bitumen roof shingles. These not only look elegant but also offer excellent protection against rain, snow, and UV radiation. The shingles are durable, require little maintenance, and underscore the overall high-quality appearance of the sauna.

A complete sauna accessory set is included: a thermometer and hygrometer for monitoring temperature and humidity, as well as a high-quality bucket with ladle. This allows you to immediately begin your first sauna sessions and atmospheric infusions.

The aspen wood floor slats protect your feet from direct contact with the cold floor and allow for good air circulation in the floor area. The backrests ensure relaxed seating positions, while the bench panels create a visually cohesive and high-quality interior design.

Kit or fully assembled – the choice is yours.

The Cube Premium is delivered as a high-quality kit as standard. All components are precisely prefabricated, numbered, and supplied along with detailed assembly instructions and all necessary mounting hardware. With some skill and assistance, DIY-savvy garden owners can assemble the sauna themselves – a worthwhile project where you can experience the quality of each individual component firsthand.

For those who prefer the convenience of a ready-to-use solution, the Cube Premium can also be ordered fully assembled. Experienced professionals will then handle the complete setup, allowing you to focus on what matters most: the anticipation of your first sauna session.

Both options offer the same outstanding quality – the decision is entirely up to you and your individual preferences.

A place for all seasons, all occasions

The Cube Premium is designed for year-round use. Its solid log construction and high-quality materials withstand all weather conditions – whether summer heat, autumn storms, or winter frost.

After a long day at work, it offers you an immediate retreat. No travel, no waiting – just minutes after arriving home, you can relax in soothing warmth and leave the day behind.

On weekends, the sauna becomes a wellness ritual that you consciously treat yourself to. Time for yourself, for mindfulness, for the conscious care of body and mind.

And for social occasions, your Cube Premium transforms into a special meeting place: Leave everyday life behind with friends or family, get together for a sauna infusion, then cool off in the garden – these shared experiences create connections and remain in memory.
