Choosing maximum length within a familiar, established silhouette rather than moving to a wider variant suits households who've specifically settled on the cube format's particular look and don't want to change those proportions even while seeking more capacity. The core physiological benefits of sauna bathing, improved circulation, reduced muscle tension, a cardiovascular effect comparable to light exercise, remain consistent regardless of which specific model within the range is chosen.

For households planning a genuine garden centrepiece around their sauna, the Icon 250s offers serious group capacity, comfortably fitting four to five people, while retaining the recognisable cube aesthetic that drew them to this particular range over a barrel or oval alternative. That consistency of visual identity alongside genuine scale matters for households who've put real thought into how their sauna fits the wider garden design.

Group sauna sessions specifically support social and mood benefits that solo use doesn't fully capture, and a sauna with adequate room for four or five people removes the friction that a too-small cabin would create for regular, consistent group use. For households who've decided the cube format and its established proportions suit their garden best, this model delivers the genuine capacity to match that aesthetic preference without compromise.
Delivered flat packed for self-assembly, with free UK mainland delivery on qualifying orders. As the longest standard Icon, this build takes a little longer than the shorter models, best tackled over a weekend with a helper. Needs a solid, level base and clear access. Professional installation available as an upgrade; see our Self Assembly Guide.
The Icon 250s needs standard Icon range care, applied across its maximum standard length. After every session, leave the door open for twenty to thirty minutes to let the heat room dry out fully, preventing mould and dark staining on timber surfaces. Wipe benches down once cooled, and sand the interior lightly once or twice a year wherever group use creates the most contact wear.

If fitted with the optional window, clean it with a standard glass cleaner and soft cloth. Check the door seal periodically given the more frequent use this size is likely to see.

Externally, treat the Thermowood exterior with a wood treatment every two to three years, budgeting proportionally more time for this longer structure compared with smaller Icon sizes. Keep the base clear of debris and standing water along the full extended footprint, checking drainage carefully given the greater length of timber in contact with the ground.
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). If your order exceeds this due to length, weight, or quantity, additional pallet charges may apply and are quoted separately based on postcode. 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.

Maximum length, same familiar cube look

Icon 250s sits at the top of the standard diameter Icon range, extending to 250 centimetres in length while keeping the consistent 205 centimetre diameter found throughout the smaller models. Solid Thermowood construction throughout gives the structure genuine thermal mass at this larger scale, holding heat efficiently even with a full group inside and the additional heat loss that comes with more frequent door use.

At this length, Icon 250s suits households who want the largest available size within the standard 205 centimetre diameter Icon format, rather than moving to the wider XL versions that change the underlying diameter rather than simply extending the length. This keeps the proportions and overall feel of the cube format consistent with the smaller models, just stretched out to accommodate a proper group session comfortably.

Icon 250s suits anyone who has decided the standard Icon diameter suits their needs well enough that they simply want the maximum length available within that specification, delivering serious group capacity without changing the fundamental character of the format they were originally drawn to. It rounds out the standard diameter line at the size most suited to genuine family or group sessions, giving the format every bit of length it can offer before stepping up to a wider diameter altogether.
