Product information

Built to sit close to where you already gather. Terrace Sauna pairs a 160cm length with a 230cm diameter, solid Thermowood construction giving genuine thermal performance with a touch more breathing room than the narrower Ergo range. Positioned near existing decking or seating rather than across the garden. Proximity that makes regular use far more likely, especially through colder months.

Proximity and convenience matter more than people often expect when it comes to actually maintaining a regular sauna habit. A sauna positioned within easy reach of existing outdoor seating, rather than requiring a special trip across the garden, removes a small but real piece of friction that otherwise discourages spontaneous, regular use. Many owners genuinely find that a sauna they can step into easily after relaxing on a terrace gets used far more consistently than one that feels like a separate destination requiring deliberate planning.

The core physiological benefits of sauna bathing, improved circulation, eased muscle tension, a cardiovascular effect comparable to light exercise, depend heavily on regular, repeated use to deliver their full long-term value. Anything that supports that consistency, including simple positioning and convenience, genuinely contributes to better outcomes over time compared with an equally well-built sauna that's just slightly less convenient to reach.

The built-in deck terrace adds a further practical dimension, giving somewhere to sit and transition immediately before or after a session without needing separate decking elsewhere in the garden. For households who already value their outdoor terrace as a relaxing space, extending that same ease and comfort directly to the sauna experience tends to support exactly the kind of low-friction, regular use that turns sauna bathing into a genuine lasting habit rather than an occasional event.
Delivered flat packed for self-assembly, with free UK mainland delivery on qualifying orders. The built-in deck terrace adds a little extra to the build beyond the standard barrel structure, manageable over a weekend with a helper. Needs a solid, level base spanning both the sauna and decked area. Professional installation available as an upgrade; see our Self Assembly Guide.
The Terrace Sauna needs the same fundamental barrel sauna care as the rest of the range, with some extra attention to the built-in deck terrace given its different exposure and use. After every session, leave the door open for twenty to thirty minutes to let the heat room dry out fully, preventing mould and staining on the interior timber. Wipe benches down once cooled, and sand the interior lightly once or twice a year wherever contact is heaviest.

The built-in deck terrace, being a walked-on outdoor surface, should be checked periodically for general wear and slipperiness, particularly in wet weather, and treated with an appropriate decking oil or treatment on a similar cycle to the main sauna exterior.

Externally, treat the curved Thermowood exterior with a wood treatment every two to three years depending on weather exposure. Given its position close to existing outdoor living space, check that water from the main structure and the attached deck both drain away properly rather than pooling near the base, since proximity to other hard landscaping can sometimes affect natural drainage patterns.
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.

A sauna that sits right by your terrace

Terrace Sauna is built at a 160 centimetre length with a 230 centimetre diameter, sized and named for positioning on or near a terrace area rather than freestanding in the open garden. Solid Thermowood construction throughout gives the curved barrel structure genuine thermal performance, with the slightly wider 230 centimetre diameter compared with the Ergo range giving a touch more interior breathing room at a similar overall length.

The terrace positioning concept suits households who want their sauna close to existing outdoor seating or decking, keeping the whole wellness routine within a connected outdoor living space rather than requiring guests or family members to walk across the garden to reach it separately. This proximity matters more than it might initially seem, particularly through colder months when the distance between the house and a freestanding sauna at the far end of a garden can feel considerably longer than it actually is.

Terrace Sauna suits anyone planning their outdoor space around a connected wellness area, where the sauna sits as part of a broader terrace or decking layout rather than as an isolated feature elsewhere in the garden, making regular use that much more likely simply through convenience and proximity. A sauna a few steps from the back door tends to get used far more often than one tucked away at the bottom of the lawn.
