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 maximum length, wider diameter, and two-room plus terrace layout make this a substantial build, best planned over a full week with experienced help. Needs a solid, level base and good access. Professional installation is strongly recommended; see our Self Assembly Guide.
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 Thermowood 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.

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 Thermowood 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.
