Product information

Thirty extra centimetres, a genuinely different feel. Ergo 180 keeps the 205cm diameter of the smaller Ergo but extends to 180cm in length, solid Thermowood construction giving real room to lie back rather than just sit upright. The barrel shape distributes heat evenly without any extra engineering required. A sensible step up for anyone who found the 150 slightly too tight.

Premium Thermowood

Built to age beautifully. Thermowood offers a richer finish, stronger durability, and better long-term performance.
The extra length on this model is built specifically to support a more relaxed, reclined sauna posture, which many regular users find makes a genuine difference to how comfortable and enjoyable longer sessions feel. Being able to properly lie back rather than sit upright for the full duration tends to encourage people to stay in the heat longer, and longer, more relaxed sessions are associated with deeper relaxation benefits than a quick, slightly cramped sit.

The core physiological effects of sauna bathing remain consistent regardless of bench length: heat exposure raises heart rate and improves circulation in a way comparable to light cardiovascular exercise, with regular use linked to improved long-term cardiovascular markers in research on habitual sauna bathers. What changes with genuine comfort is consistency, since a sauna that feels properly relaxing rather than slightly cramped tends to get used more willingly and more often.

For couples or small households specifically, this size strikes a practical balance: enough room for comfortable shared use without the larger footprint and cost of a group-focused model built for capacities rarely needed in everyday personal use. That balance of genuine comfort and sensible scale tends to suit the realistic, regular usage patterns of most households better than either extreme.
Delivered flat packed for self-assembly, with free UK mainland delivery on qualifying orders. The slightly longer barrel takes a little more time than the 150, best tackled over a weekend for most competent DIYers. Needs a solid, level base and clear access. Professional installation available as an upgrade; see our Self Assembly Guide.
The Ergo 180 needs the same straightforward barrel sauna care as the rest of the range. 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 over time. Wipe down the ergonomic benches once cooled, and give the interior a light sand once or twice a year wherever contact is heaviest, particularly given this model's design for more reclined, longer use.

Leave the timber interior unsealed to allow it to breathe and absorb moisture properly during sessions. If you've added the optional glazed end, it needs only a standard glass cleaner and soft cloth.

Externally, treat the curved Thermowood exterior with a wood treatment every two to three years depending on weather exposure. Check the door seal each season, and keep the base area clear of leaves and standing water, the same principle that applies to any outdoor timber sauna regardless of size within the range.
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.

Enough room to properly lie back

Ergo 180 steps up from the 150 to a 180 centimetre length while keeping the same 205 centimetre diameter, solid Thermowood construction giving meaningfully more interior room without changing the fundamental barrel proportions that make this format work so well. The extra 30 centimetres makes a genuine difference to how comfortable the space feels, particularly for anyone wanting to lie back rather than simply sit upright during a session.

The barrel format continues to distribute heat evenly throughout the curved interior, a structural advantage that comes naturally from the shape itself rather than requiring any additional engineering or ventilation tricks to achieve. Solid Thermowood throughout provides the durability needed for genuine outdoor use across every UK season, standing up to wind, rain, and frost without the structure suffering for it over years of regular use.

Ergo 180 suits anyone who found the 150 slightly too tight for comfortable use, offering a sensible step up in length without moving into the largest sizes the Ergo range or wider barrel sauna catalogue has to offer, a practical middle ground for personal or couple use that still leaves room to genuinely relax. It tends to be the size couples settle on once they have tried the smallest option and decided they wanted just a little more breathing room to stretch out properly during a session.
