Sun Home Solaris: what the documentation says
Sun Home's outdoor traditional sauna, delivered as a fully built structure in four- and six-person sizes. The published specification is detailed — and its weight and circuit tell you most of what the project involves.
The Solaris is Sun Home's outdoor traditional sauna: a real heater, stones and water, up to 230 °F by Sun Home's figure, built from thermally modified alder and delivered as a finished structure rather than a flat-pack. It comes in four- and six-person sizes, and its published weight and electrical requirement tell a buyer a great deal about the installation before any other question is asked.

Sun Home states the Solaris needs a level, load-bearing outdoor pad and a clear path for delivery of a fully built structure, and that a licensed electrician hardwires it. Figures read from Sun Home's product pages on 2026-09-11.
What the specification tells you about the project
Weight. At roughly 1,700 to 1,900 pounds, the Solaris needs a proper foundation — a level, load-bearing pad, not a patch of lawn — and our foundation guide covers the options. Because it arrives built, the delivery route matters as much as the pad: a finished structure cannot be carried through a side gate in pieces.
Electrical. A hardwired 25 A or 40 A circuit is an electrician's job and, in most places, a permit. That is normal for a traditional heater of this size and it is the cost most people underestimate; the electrical guide explains what the run involves.
Heater. Sun Home specifies HUUM heaters — the exposed-stone design we compare with Harvia in Harvia vs HUUM. A named heater brand means a published spec sheet and a parts channel, which matters most on the component most likely to need service.
Warranty. Three years on the outdoor Solaris, against the limited lifetime warranty Sun Home publishes on several indoor models. That is a meaningful difference worth weighing, and it reflects what an outdoor structure faces.
What we could not verify
- Insulation specification — wall build-up or R-value, which matters for winter warm-up.
- Roof covering details beyond the published photographs.
- Interior bench dimensions, as opposed to exterior dimensions.
- Warm-up time in cold conditions.
- A first-party Amazon listing. Sun Home sells direct.
Alternatives you can buy today
If you want an outdoor traditional sauna through a normal retail channel now, the picks below are in the class. They are not Sun Home products. Most arrive as kits you assemble rather than finished structures, which is a large part of the price difference — and a large part of the work.
Outdoor traditional alternatives on Amazon
4-Person Outdoor Barrel Sauna, Canadian Cedar, 6 kW Harvia
Generic Amazon listing
#ad Price as of Sep 27, 2026. We earn a commission if you buy, at no extra cost to you. How this is funded.
Cedar shell, named-brand heater, four-person capacity — the three things that actually decide whether a barrel sauna is still good in year five.
| Capacity | 4 person |
|---|---|
| Height | 78" |
| Wood | Canadian cedar |
| Heater | 6 kW Harvia |
| Type | Traditional, vertical barrel |
| Circuit | 240 V — required for a 6 kW heater |
| Roof covering | Not published in the listing |
What works
- A Harvia heater means a published spec sheet and a real parts channel
- Cedar is the correct wood for a structure that lives outside year round
- 6 kW is properly sized for a four-person barrel volume
What doesn't
- A 240 V run to the yard is a real, permitted expense
- Roof covering is not specified, and barrels leak at the top first
- Freight delivery with a curbside drop — you move it yourself
Skip it ifyour yard has no realistic path for a 240 V run. Trenching a circuit to the back of a garden regularly costs more than the sauna, and it is not a corner worth cutting.
ALEKO Liatris Barrel Sauna, 5–6 Person, 6 kW Harvia
ALEKO
#ad We earn a commission if you buy, at no extra cost to you. How this is funded.
The UL certification on the heater is the detail worth paying for — it is what your insurer and your electrical inspector will ask about.
| Capacity | 5–6 person |
|---|---|
| Wood | Rustic cedar |
| Heater | 6 kW Harvia, UL certified |
| Porch | Front porch canopy |
| Type | Dry and wet steam |
| Circuit | 240 V |
What works
- UL certification stated explicitly, which most listings avoid mentioning
- A front canopy keeps rain off the door — a real longevity feature
- Six-person capacity is unusual in a barrel
What doesn't
- 6 kW is undersized for a genuine six-person volume — expect long warm-ups when full
- Rustic cedar grading means more knots than clear cedar
- A very large footprint for a suburban yard
Skip it ifyou regularly fill it. At 6 kW into a six-person barrel a full house is a 60-minute-plus warm-up; the four-person model with the same heater gets hot far faster.
AYCHLG Western Red Cedar Outdoor Barrel Sauna, 6 kW
AYCHLG
#ad Price as of Sep 27, 2026. We earn a commission if you buy, at no extra cost to you. How this is funded.
Western red cedar specifically, not 'cedar' as a marketing word. The species matters for how a barrel handles a wet-dry-freeze cycle.
| Capacity | 2–6 person (as listed) |
|---|---|
| Wood | Canadian western red cedar |
| Heater | 6 kW, wet or dry |
| Type | Traditional barrel |
| Circuit | 240 V |
| Roof covering | Not published |
| Heater brand | Not published |
What works
- Names the actual species rather than the generic word 'cedar'
- A wet-or-dry heater covers both use patterns
- Wide stated capacity range
What doesn't
- A '2–6 person' range is marketing, not a spec
- Roof covering unpublished — the first thing to fail on a barrel
- No stated heater brand
Skip it ifyou want a named heater brand. An unbranded 6 kW element works until it does not, and then you are hunting for a replacement that fits the same opening.
Smartmak Outdoor Square Sauna, 6–8 Person, Wood-Burning
Smartmak
#ad Price as of Sep 27, 2026. We earn a commission if you buy, at no extra cost to you. How this is funded.
A cube shape and a wood stove together mean no trench, no permit and no electrician — the install cost that sinks most outdoor sauna projects simply is not there.
| Capacity | 6–8 person |
|---|---|
| Shape | Square / cube |
| Wood | Hemlock |
| Heater | Wood-burning stove |
| Roof | Waterproof asphalt shingles |
| Power required | None for the stove |
| Accessories | Included |
What works
- Wood fired means zero electrical infrastructure
- An asphalt shingle roof is actually specified, which barrels rarely are
- Cube geometry uses interior volume better than a barrel at the same footprint
What doesn't
- Hemlock outdoors is a worse choice than cedar over a decade
- Wood firing means a 45-minute lead time and ash management every session
- A chimney through a roof needs correct clearances
Skip it ifyou want heat on a schedule. Wood-fired saunas reward planning and punish spontaneity.
Our honest position
The Solaris's strongest selling points are the ones a kit cannot match: delivery as a finished structure, a named premium heater and a fully published specification. Its weight and hardwired circuit are the project, not a footnote, and they belong in your budget before the cabin does. If you want one, buy it from Sun Home directly. If a kit and a weekend of assembly suit you better, the alternatives above reach the same heat, and our 4-person outdoor sauna page goes deeper on matching heater to room.
