Bespoke wood-fired sauna and wellness space
A barrel sauna's curved profile isn't purely aesthetic; the rounded walls promote more even heat circulation throughout the cabin than a square-cornered alternative, where hot air can otherwise collect unevenly. For personal or couple use specifically, this means a more consistently warm experience throughout a session, supporting the core physiological benefits of sauna bathing: improved circulation, reduced muscle tension, and a cardiovascular effect comparable to light exercise.

For anyone new to sauna ownership, an affordable, appropriately sized entry point like this removes a real barrier to starting a regular habit. Committing to a large, expensive group-focused sauna before knowing how often it'll actually get used can feel like a significant risk, whereas a compact personal model lets a household build genuine consistency first, which research on habitual sauna users consistently identifies as the key factor driving long-term cardiovascular and wellbeing benefits.

The ergonomic bench design adds genuine comfort to that consistency, supporting a more relaxed, properly seated or reclined position rather than perching upright on a flat bench. Comfort during a session matters more than people often expect when it comes to whether they actually use a sauna regularly or let it become an occasional, underused feature, making thoughtful bench design a practical investment in long-term habit building, not just a nice-to-have detail.
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.

Barrel saunas need straightforward, regular care to keep performing well for years. 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 dark staining on timber surfaces. Wipe down the ergonomic benches once cooled, since sweat left to dry on the wood will leave a residue over time.

Give the interior a light sand once or twice a year wherever the ergonomic benches and backrests see the most contact. Leave the timber interior unsealed, since sauna wood needs to breathe and absorb moisture during use rather than sit under a coating that would trap it.

Externally, the curved Thermowood exterior needs a wood treatment reapplied every two to three years depending on weather exposure, with the curved surface actually shedding rainwater slightly more effectively than a flat-walled cabin. Check the door seal periodically, and keep the area around the base clear of leaves and standing water, since pooling moisture against the lowest timber courses remains the most common cause of long-term damage on any outdoor sauna regardless of shape.
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.

Barrel Sauna Ergo 150 — 1-2 Person Thermowood Sauna, 1.5m — thermowood — angle view 1

An affordable entry into barrel saunas

Ergo 150 brings the classic barrel sauna format to a compact 150 centimetre length with a 205 centimetre diameter, solid Thermowood construction giving the curved structure genuine thermal mass despite its relatively modest overall footprint. The barrel shape is one of the most traditional and recognisable outdoor sauna formats, the curved roof naturally encouraging heat to circulate evenly throughout the interior space.

At this length, Ergo 150 suits personal or couple use rather than larger group sessions, a sensible entry point into barrel sauna ownership for anyone drawn to the format who does not need the largest available size. The 205 centimetre diameter remains consistent with several other models in the Ergo and standard sauna ranges, meaning the proportions feel familiar and properly balanced rather than unusually cramped for the format.

Ergo 150 suits anyone wanting a genuine barrel sauna experience without committing to a longer structure, the kind of size that fits efficiently into a smaller garden while still delivering the authentic curved profile and even heat distribution that makes barrel saunas such an enduringly popular outdoor sauna format. Many owners find this compact size gets used just as often as a larger sauna would, simply because it is always there and ready.
