Panoramic garden sauna beside square mobile and horsebox saunas

Greenhouse and box saunas

By the zauna editorial team · Updated 11 October 2026

The supplied sources do not establish a greenhouse sauna specification or explain how it differs from a box sauna. They do document panoramic garden saunas, square mobile models and horsebox builds. If you are comparing these options, focus on the stated layout, capacity and complete specification rather than treating the names as equivalent.

What do the sources tell you about greenhouse saunas?

There is not enough information here to describe a greenhouse sauna as a defined product type. The Lichfield Garden Buildings source has a title about greenhouse glass and polycarbonate. Its supplied extract, however, shows a garden-building collection rather than a sauna specification or a comparison of glazing materials.

That leaves an important gap. The extract does not establish which glazing is suitable for a sauna, how a greenhouse sauna is heated or what its construction should include. It cannot support a recommendation to convert a greenhouse.

If your search for a greenhouse sauna is about having a view from inside, the Polhus listings offer a more specific starting point. Several models are described as having panoramic views. That description does not establish that they are greenhouse saunas, but it gives you a documented feature to compare.

Which garden saunas offer views or privacy?

Polhus lists Sauna Minna at 4.3 m² for four to six people, with a panoramic view and a listed price of £3,990. Sauna Narvik is listed at 2.2 m² for two to three people, also with a panoramic view, at £3,990. Sauna Lumi has the same stated area and capacity as Narvik, with a listed price of £3,790.

The collection also includes models described as designed for privacy. Sauna Jorma is listed at 5.0 m² for four to six people at £3,690. Sauna Ritva is listed at 4.3 m² for four to six people at £3,790.

Compare those descriptions with what you want from your garden sauna. The supplied collection gives areas, capacities and selected features. It does not provide enough detail to compare the glazing construction or heating performance of these models.

What box and trailer sauna examples are documented?

The sources document several different mobile formats rather than one shared box-sauna specification. TimberIN lists its Nordic Square Mobile Sauna from £6,936, alongside mobile barrel and pod models. Its guidance says that a starting price or body size does not describe the complete purchase. Where a trailer is optional, it must be selected separately.

Sauna Box builds horsebox saunas to order in Suffolk for operators, glamping sites and hotels. Its stated capacity is six to eight people. The L-shaped bench layout seats six to seven, while the parallel-bench layout seats eight.

A separate Ifor Williams Trailers report describes Finnmark’s wood-burning demonstration sauna built in a box van trailer. This is a documented example of a trailer conversion, not evidence that every product described as a box sauna has the same layout, materials or intended use.

How do the mobile specifications compare?

Sauna Box lists thermo aspen lining, a Narvi heater and LED lighting as standard. Its horsebox specification gives overall dimensions of 4.61 metres long, 2.30 metres wide and 2.79 metres high. The layout descriptions separately give an approximate trailer footprint of 4.6 by 2.2 metres. These are different measurements on the same page, so ask which dimensions apply to your proposed unit.

Awaken’s mobile sauna listing gives dimensions of 3.2 by 2.2 metres. It describes a galvanised twin-axle trailer, Scandinavian redwood interior, metal frame, blackout glass door and window, and a Harvia wood-burning stove. Hidden LED lighting and an EPDM roof are also listed.

The supplied descriptions are not like-for-like specifications. Use them to identify questions for the builders, rather than assuming that the quoted dimensions cover the same parts of each finished trailer.

What should you confirm before buying?

Ask for a written specification for the complete sauna and, where relevant, its trailer. TimberIN specifically recommends confirming the completed assembly’s mass, dimensions, equipment and road-use documents. Its guidance also distinguishes travelling from parked operation and site services.

Check what each price covers. Sauna Box gives a guide price from £33,000 excluding VAT, with delivery priced by location. Its listed build time is 22–23 days, but the workshop lead time is agreed against your required date. Those are separate timings.

Awaken builds to order in Dungannon and asks buyers to request the current build window. It offers custom sizing and delivery across the UK and Ireland. Sauna Box offers a Suffolk workshop visit or a video walk-round; Awaken also welcomes workshop visits. You can use these opportunities to discuss the listed materials and layout. For electrical work, use a qualified electrician.

Questions people ask

Is a greenhouse sauna the same as a panoramic sauna?
The supplied sources do not establish that they are equivalent. Polhus describes several garden saunas as having panoramic views, but the extracts do not identify them as greenhouse saunas.
Can you use greenhouse glass or polycarbonate for a sauna?
The supplied material does not establish whether either is suitable. The greenhouse-titled source contains no relevant sauna glazing specification, so it cannot support a materials recommendation.
How many people fit in the Sauna Box horsebox?
Sauna Box states an overall capacity of six to eight people. Its L-shaped bench layout seats six to seven, while its parallel-bench layout seats eight.
Does a mobile sauna starting price include the trailer?
Do not assume it does. TimberIN says that some models have a separately selectable trailer. Ask for the price and written specification of the complete assembly.
Can you order a custom-sized mobile sauna?
Awaken states that custom sizing is available. You can discuss your required size with its team and request a quote.
