Sun Home Equinox: what the documentation says
A spec-led look at Sun Home's full-spectrum cabin, the questions its documentation leaves open, and what is actually buyable in the same class today.
Sun Home is one of the more visible names in premium home saunas, and the Equinox is its full-spectrum cabin. It attracts a lot of search interest, so it is worth setting out what a buyer can actually establish from published sources — and where those sources go quiet.
What the class involves
A full-spectrum cabin at this tier combines near, mid and far infrared emitters, typically with some degree of band selection, in a cabinet built to a higher standard of joinery and timber grade than the mid-market. Power draw is materially higher than a far-infrared cabin, which means a 220 V or 240 V circuit and an electrician.
Sun Home's marketing places significant weight on low EMF and on full-spectrum output. Both are reasonable things to lead with. Both also raise the same question we put to every manufacturer in this category, and it is the question worth taking into a sales call.
The questions to ask before buying
| Question | Why it matters |
|---|---|
| EMF figure, and the distance it was measured at | An EMF number without a distance cannot be compared to any other manufacturer's number. |
| Measured wall draw and required circuit | Determines your install cost, which is not in the sticker price. |
| Near-infrared irradiance at a stated distance | The only way to know what the full-spectrum claim actually delivers. |
| Interior bench depth and internal height | Exterior dimensions tell you about the room, not about you. |
| Warranty, per component, in years | Heaters, electronics and cabinet are usually covered differently. |
| Delivery and installation scope | Curbside freight versus assembled and commissioned is a large practical difference. |
A manufacturer that answers the first and third rows with numbers and distances is giving you something you can check. Very few in this category do. That is not a comment on Sun Home specifically — it is the state of the whole market, and it is why our EMF comparison page exists.
What we could not verify
- A first-party Amazon listing. Our search for one returned no confirmed result, and we are not going to link a third-party reseller as though it were the manufacturer.
- A published EMF figure with a stated measurement distance.
- A published near-infrared irradiance figure at a stated distance.
- Interior bench dimensions, as opposed to exterior cabinet dimensions.
Absence of publication is not evidence of a bad product. It is evidence that a buyer cannot compare on those axes from published material, which means the sales conversation is where the comparison has to happen.
Alternatives you can buy today
If what you want is a full-spectrum three-person cabin available now through a normal retail channel, the picks below are in that class. They are not Sun Home units and we are not suggesting they are equivalent in build quality — they are what exists in the same category at a different tier, with the specifications each seller chose to publish.

Duthss 3-Person Full-Spectrum Infrared Sauna

#ad We earn a commission if you buy, at no extra cost to you. How this is funded.
Full spectrum at this size means a 220 V circuit, and the listing says so instead of burying it. That single line is worth more than the whole feature list.
| Capacity | 3 person |
|---|---|
| Power draw | 3,600 W |
| Voltage | 220 V |
| Interior | 60" W × 41" D × 75" H |
| Heaters | 4 carbon panels plus 4 red-light tubes |
| Wood | Hemlock |
| Extras | Foot heating, insulated glass |
What works
- Publishes interior dimensions, not just the outside box
- Foot heating addresses the most common complaint about infrared cabins
- The 220 V requirement is stated openly rather than discovered on delivery day
What doesn't
- 220 V means an electrician, a permit in most jurisdictions and a real install cost
- No EMF figure published
- 3,600 W is expensive to run — check the arithmetic before you commit
Skip it ifyou are not prepared to add a 220 V circuit. Budget the electrical work before the cabin, because on this unit the wiring is not optional.
Smartmak 3-Person Full-Spectrum Infrared Sauna

Eleven elements across 2,100 W means each one is modest: good for even coverage, less good if you were expecting the aggressive radiant punch of a few high-output panels.
| Capacity | 3 person |
|---|---|
| Power draw | 2,100 W |
| Heating elements | 11 |
| Wood | Canadian hemlock |
| Spectrum | Full-spectrum with red light |
| Extras | Wi-Fi control, speaker |
| EMF, as published | Not published |
What works
- Element count is published, which lets you reason about distribution
- 2,100 W keeps it inside a standard 20 A circuit
- Wi-Fi preheat is genuinely useful on a cabin with a long warm-up
What doesn't
- Spreading 2,100 W over 11 elements limits peak radiant intensity
- No EMF figure
- Some listed features are novelties we would not pay for and cannot assess
Skip it ifyou are upgrading specifically for stronger radiant intensity. More elements is not more power — the 2,100 W total is the number that matters.
RESTISLAND 3-Person Far Infrared Sauna

It publishes both the wattage and the circuit it needs — the pair of numbers that actually decides whether you can install a sauna where you want it.
| Capacity | 3 person |
|---|---|
| Power draw | 2,240 W |
| Circuit | 20 A |
| Wood | Canadian hemlock |
| Extras | 7-color chromotherapy, Bluetooth speakers |
| EMF, as published | Described as low EMF; no figure given |
| Spectrum | Far infrared |
What works
- States the circuit requirement up front — most listings make you infer it
- 2,240 W is a real number you can run a running-cost calculation against
- Tempered glass door on a sub-premium cabin
What doesn't
- A dedicated 20 A circuit is not optional and most rooms lack a spare one
- 'Low EMF' again carries no figure
- No near infrared
Skip it ifyour only free outlet is on a shared kitchen or bathroom circuit. At 2,240 W this will trip a 15 A breaker, and an extension cord is a fire risk rather than a workaround.
Our honest position
If you want a Sun Home Equinox, buy it from Sun Home. We earn nothing either way, and a direct purchase gets you the warranty and the support that are a real part of what you are paying for at that tier.
If you are cross-shopping and the premium is what you are weighing, the useful comparison is not Equinox against a cheaper cabin — it is Equinox against a well-specified far-infrared cabin plus a standalone red light panel. That combination gives you both wavelength ranges with control over the near-infrared distance, which no built-in emitter offers.
