At this scale, combining maximum length, maximum width, and a genuine multi-room layout, a sauna stops being a single household amenity and starts functioning as serious infrastructure for regular wellness use, whether for a large family, a friend group, or a commercial hospitality setting. The core physiological benefits of sauna bathing, improved circulation, reduced muscle tension, a cardiovascular effect comparable to light exercise, remain consistent regardless of scale, but the capacity to genuinely host eight to ten people without compromise opens up a different category of use altogether.

The two-room layout plus terrace adds real practical value at this scale, separating the heat room from changing and outdoor seating space in a way that supports a considered, unhurried ritual even with larger groups regularly using the structure. For glamping operators and holiday lets specifically, offering a genuinely spacious, well-laid-out sauna experience taps into the established social and wellbeing benefits of group sauna bathing, something increasingly valued by guests seeking a real wellness amenity rather than a token feature.

For households who've decided they want everything the Icon range can offer, this model represents the format's fullest expression: maximum room to move, maximum capacity, and a layout built to support genuine, regular group use across a full UK year. That combination of scale and consideration tends to support the kind of consistent, repeated group habit that delivers the most meaningful long-term wellbeing benefits for everyone using the space.
Delivered flat-packed for self-assembly, with free UK mainland delivery on qualifying orders. The larger Cube format requires a little more assembly time than the smaller Icon models, so we recommend allowing a weekend and having a second person to help. A solid, level base and suitable delivery access are required.

For a complete setup, select Professional Installation and choose your preferred date, allowing for the stated production lead time. We’ll then arrange the installation around your requirements, including any additional preparation or works needed to accommodate your sauna where possible.

Electric sauna heaters require a suitable dedicated electrical supply and are not simply plug-and-play. The power requirements depend on the heater's output and the electrical supply available at the property.

Smaller heaters may be suitable for a 230V single-phase supply, while larger or more powerful heaters can require a 400V three-phase supply. Single-phase power uses one electrical phase, whereas three-phase power distributes the load across three phases and is better suited to higher-powered equipment.

The correct supply will depend on the specific heater you choose, so the heater's electrical requirements should always be checked before installation.

Sauna heaters will normally need to be hard-wired into a correctly rated dedicated circuit with the appropriate cable, isolation and electrical protection. They should not be connected using a standard household plug or extension lead.

The final electrical connection should be completed by a suitably qualified electrician in accordance with the heater manufacturer's instructions and applicable electrical regulations. This is important for both safety and reliable operation of the heater.

If you're based in the Leicestershire area, we can arrange the electrical installation of your sauna heater for an additional fee. Please speak to our team if you'd like this included with your sauna.

Wood-fired sauna heaters do not require an electrical supply for heating, but they do require the correct installation of the stove, chimney, flue and surrounding heat protection.

The stove must be positioned according to the manufacturer's required safety distances from timber walls, benches and other combustible materials. Depending on the stove and sauna design, suitable heat shields or other non-combustible protection may also be required.

The floor beneath and immediately around the stove may also require suitable non-combustible protection, particularly where there is a risk of embers or hot material falling from the stove.

A suitable chimney and flue system must be installed to safely carry smoke and combustion gases outside the sauna. Where the flue passes through the roof, the correct insulated chimney components, roof flashing and heat-resistant protection should be used.

Correct ventilation is also important. A wood-fired stove requires an adequate supply of combustion air, while the sauna itself needs sufficient airflow to provide fresh air, circulate heat and allow moisture to escape.

When choosing the position of an outdoor wood-fired sauna, you should also consider where the chimney will discharge in relation to your house, neighbouring properties, windows, boundaries and outdoor seating areas.

Any applicable local requirements should be checked before installation, particularly where chimney positioning, smoke control or other restrictions may apply.

A sauna of this scale rewards a more organised maintenance approach given the considerably larger surface area across the heat room, changing area, and terrace. After every session, prop the heat room door open for twenty to thirty minutes to let moisture escape fully, the most effective habit for preventing mould and dark staining regardless of structure size. Wipe benches down once cooled, and sand the interior lightly once or twice a year wherever group use creates the most contact wear.

The changing area and terrace, given their different use and exposure, should be checked separately for general wear and dampness, with the terrace decking treated on a similar cycle to the main exterior. If fitted with a window, clean it with a standard glass cleaner and soft cloth.

Externally, treat the full Spruce exterior on a two to three year cycle, though a structure this size is worth tackling in sections across a season rather than all at once. Check the full base perimeter for debris and standing water, given the considerably larger footprint this combined structure occupies compared with smaller Icon models.
This sauna comes with a 5 year warranty for residential use and 2 years for commercial use, covering structural timber, glazing, and hardware. Valid claims are assessed case by case, and we'll supply replacement parts wherever possible rather than the whole sauna.
Production takes 10-12 weeks, plus 1-2 weeks dispatch time for pallet haulage. This sauna is delivered flat packed unless otherwise stated. Free UK mainland shipping applies to orders over £500 covering up to one double pallet (2.4m x 1.2m x 2.2m) or two single pallets (1.2m x 1.2m x 2.2m). Given this model's size and weight, additional pallet charges may apply and will be quoted separately based on your postcode, and forklift unloading may be required as it exceeds normal tail-lift limits (1000kg). Please have a solid base, clear access, and suitable unloading space ready before delivery, with help on site if needed. Pallet deliveries are kerbside only, and you're responsible for moving goods onto your property.

Cube Sauna Icon 385 XL — Largest Spruce Cube Sauna, 3.85m — spruce — angle view 1

Everything the icon range can offer

Icon 385 XL sits at the very top of the Icon range, extending to 385 centimetres in length while keeping the wider 226 centimetre diameter introduced in the 220 XL model. Solid spruce construction throughout gives the structure genuine thermal mass at this substantial scale, the combination of extra length and extra diameter together delivering by far the most spacious interior available within the entire Icon format.

At this size, Icon 385 XL suits households who have decided they want everything the Icon line can offer, maximum length, maximum diameter, and the kind of group capacity that genuinely rivals the largest standard barrel saunas elsewhere in the range while still keeping the distinctive cube aesthetic that sets the Icon series apart visually. This is a serious commitment to outdoor sauna ownership rather than a modest addition to the garden.

Icon 385 XL suits anyone planning a genuinely substantial outdoor sauna built around the cube format specifically, delivering the largest capacity the Icon range offers without compromising on the wider diameter that makes the XL models feel meaningfully different from the standard sized options earlier in the line. It is the model that defines what the Icon format is capable of at its absolute fullest extent, the natural endpoint for anyone who started out drawn to the cube silhouette and simply wanted more of everything.
