Solid Thermowood construction holds heat efficiently across longer sessions with more people inside. Built for households who decided from the outset that barrel sauna ownership deserved the larger size, not a smaller starting point.

A barrel sauna sized properly for group use from the outset tends to get used more consistently by friend groups and families than a compact model that becomes a squeeze the moment more than two people want to join. The core benefits of sauna bathing, improved circulation, reduced muscle tension, a cardiovascular response comparable to light exercise, apply regardless of group size, but the social dimension of bathing together rather than rotating through a cramped cabin becomes considerably more practical with genuine room for four or five.

Group sauna use specifically supports the social and mood benefits that solo bathing doesn't fully capture, since the relaxed, unhurried environment of a sauna session naturally encourages conversation in a way that's harder to find elsewhere in daily life. Households who know they'll regularly host friends or family for sauna sessions tend to find that investing in genuine group capacity from the start avoids the frustration of a too-small cabin discouraging spontaneous group use later.

The ergonomic bench design, carried through at this larger size, continues to support comfortable seating and reclining for everyone in the group rather than a few people getting the good spots while others perch awkwardly. That genuine comfort across the full group tends to make sessions feel more relaxed and enjoyable for everyone, supporting the kind of consistent, repeated group habit that delivers the most meaningful long-term wellbeing benefits.
Delivered flat packed for self-assembly, with free UK mainland delivery on qualifying orders. The largest Ergo takes a little longer to assemble than the smaller sizes, best tackled over a weekend with a helper for the larger panels. Needs a solid, level base and clear access. Professional installation available as an upgrade; see our Self Assembly Guide.
The largest Ergo model follows identical care principles to smaller sizes in the range, simply across more bench and wall surface. After every session, leave the door open for twenty to thirty minutes to let the heat room dry out fully, the most effective habit for preventing mould and staining regardless of cabin size. Wipe down the ergonomic benches once cooled, and sand the interior lightly once or twice a year wherever group use creates the most contact wear.

Leave the timber unsealed to allow proper moisture absorption during use. If fitted with the optional glazed end, clean it with a standard glass cleaner and soft cloth.

Externally, treat the curved Thermowood exterior with a wood treatment every two to three years, budgeting slightly more time for this larger structure than the smaller Ergo sizes. Check the door seal each season, and keep the base clear of debris and standing water across the longer footprint this model has compared with the rest of 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.

The largest ergo, for genuine group use

Ergo 220 sits at the top of the Ergo range, extending to 220 centimetres in length while keeping the same 205 centimetre diameter as the smaller Ergo 150 and 180 models. Solid Thermowood construction throughout gives the structure genuine thermal mass at this larger scale, holding heat efficiently across longer sessions involving more than just one or two people sitting comfortably inside.

The extra length compared with the smaller Ergo models translates into proper room for a small group rather than just a couple, useful for households who have decided barrel sauna ownership suits their household well enough to invest in the larger end of the range from the outset rather than starting smaller and upgrading later. The consistent 205 centimetre diameter across the whole Ergo line means the proportions remain familiar and well balanced even at this longer length.

Ergo 220 suits anyone who wants the largest available size within the Ergo format specifically, rather than moving to a different barrel sauna line entirely, keeping the same recognisable diameter and build quality while simply extending the length to accommodate more people during a typical session. It is the natural choice for anyone already committed to the Ergo aesthetic who simply needed more room to match, rounding out the range at the size most suited to genuine family or group use.
