Sun Home Equinox Infrared Sauna review: 2-Person and 3-Person

Last updated July 2026 · Verified against the manufacturer's product page

The Sun Home Equinox sits at the premium tier of the home infrared sauna market, and it comes in two sizes: the 2-person at $6,099 (MSRP $6,799) and the 3-person at $6,999 (MSRP $7,699). Both are the same sauna at a different footprint: full-spectrum heating built around two 500-watt full-spectrum units plus far-infrared, a measured 0.5 milligauss EMF rating, eco-certified eucalyptus wood, and a 7-year warranty on cabinetry and heaters (3 years on controls, 1 year on glass and audio). Most brands at this price point claim some version of these specs. Sun Home publishes the third-party measurements that back them up, which is the actual reason to consider the Equinox at the price. This review covers both sizes and which one to buy.

The published-EMF story

Almost every infrared sauna brand markets itself as "low EMF." Very few publish numbers a buyer can verify against an independent measurement standard. Sun Home publishes 0.5 milligauss as the measured EMF at typical use distance, verified by an independent lab (Vitatech Electromagnetics), alongside their patented ELF shielding implementation. The number itself sits well below the levels that wellness-conscious buyers screen for.

The reason this matters is structural. EMF and ELF travel differently. EMF drops off quickly with distance from the panel. ELF travels farther. A sauna that gets EMF down by spacing the user away from the panels can still fail on ELF if the panel design doesn't include the right shielding. Sun Home's claim covers both fields and points at the specific design choice. That puts the Equinox in a different conversation than the standard-tier infrared cabins where the published spec ends at "low EMF" without further detail.

Buyers without EMF concerns may find this section pedantic. Buyers with EMF concerns are most of the reason this price tier exists.

What you actually get

The Equinox is a fixed-cabin infrared sauna with full-spectrum heating panels lining most of the interior wall surface. The 2-person runs six heaters: four far-infrared units handle the bulk of the heat-distribution work, and two full-spectrum units at 500 watts each cover the near and mid-infrared frequencies that some recovery research points to. The 3-person adds a fifth far-infrared heater to keep its wider cabin even. Either size warms up on the same schedule and seats its rated number of adults on bench seating.

Wood selection is one of Sun Home's deliberate departures from the rest of the category. The interior is eco-certified eucalyptus rather than the hemlock or red cedar that most competitors use. Eucalyptus is harder, holds up to repeated heat cycles without warping, and has none of the allergy concerns some users develop around cedar over time.

The included accessories cover what most buyers actually need on day one: interior LED lighting, Bluetooth audio, an integrated control panel, and a programmable timer with preset session lengths. Some premium-tier competitors charge extra for these. Sun Home includes them at the listed price. Note that the Equinox is Bluetooth-only. There's no Wi-Fi or app preheat on this line, a point a few owners flag after the fact.

Installation reality

This is the section most buyers wish they had read before clicking Buy. The Equinox needs a 120V, 20-amp dedicated circuit, and this holds for both sizes: the 3-person draws a bit more (roughly 18.8 amps versus the 2-person's 15.7) but runs on the same circuit and the same NEMA 5-20P plug, so stepping up in size doesn't change your electrical. A 20A dedicated circuit is not the same as a standard household outlet, which is rated for 15 amps on most American residential wiring. The distinction matters because Sun Home will ship the cabin to your address whether the circuit exists or not. If your intended room has only a 15A circuit available, you cannot run the sauna safely from it. You'll trip the breaker repeatedly or brown out the heaters, and in the worst case overheat the wiring.

The fix is straightforward but not free. A licensed electrician can pull a 20A circuit from your panel to the sauna location for $200–$600 in most US markets, more if the panel is far from the install room. Verify panel capacity before ordering. Don't rely on the existing outlet just because it accepts the plug.

Assembly itself is genuinely tool-free. Sun Home's Magne-Seal system uses magnetic panel edges to lock the walls together. Two adults can put either cabin together in about two hours. The panels are heavy. The 2-person is around 520 pounds boxed and the 3-person around 620, so plan on having help available rather than attempting solo assembly.

How it performs

Warm-up is reasonable for an infrared cabin, though not instant. Expect roughly twenty minutes to a comfortable 110–120°F and another ten to twenty to reach the 130–145°F working range; the larger 3-person takes a little longer than the 2-person. Sun Home rates the heaters to 165°F, but owners across both sizes report the usable range settling in the 130s to low 150s. Treat 165°F as the ceiling rather than the working temperature. Heat distribution is even across the interior, which is largely a function of how much panel surface area Sun Home crammed into the cabin. Cheaper infrared cabins tend to have cold spots near the door or floor; the Equinox doesn't.

Session experience is what you'd expect from a premium infrared cabin: mild air temperature, with heavy sweating inside twenty minutes and easy breathing throughout. The full-spectrum heaters add a perceptibly different quality of heat compared to far-infrared-only cabins.

Daily-use viability is high. Operating cost runs around $0.30 per session on typical residential electricity rates, and the cabin needs almost no maintenance beyond wiping benches after use. The warranty handles the failure modes most owners would worry about.

2-Person or 3-Person: which size to buy

The two sizes are the same sauna with a different footprint, so the decision is almost entirely about how many people use it at once and how much room you have.

The 2-person ($6,099) is about 51 inches wide and 520 pounds, with a bench sized for two adults side by side. The 3-person ($6,999) stretches to about 62 inches wide and 620 pounds, adds a fifth far-infrared heater to keep the larger interior even, and seats three. Its interior depth and height match the 2-person, so the extra money buys width: a wider bench and more room for two people to spread out sideways, or a comfortable third seat. Everything else is identical: the same eucalyptus interior, the same published 0.5 milligauss EMF, the same 7-year warranty, the same tool-free Magne-Seal assembly, and the same 120V/20A circuit.

Buy the 2-person if it's you or you-plus-one and floor space is tight: the smaller footprint is easier to site and $900 cheaper. Buy the 3-person if a third person will regularly join, or if you want more room to spread out per person. Either way, make sure your space can take the extra foot of width. The price step buys real interior space rather than a spec upgrade. Households of four or more have outgrown the Equinox line either way, and should look at a larger or outdoor cabin.

How it compares

The Equinox slots cleanly between two reference points readers tend to know.

Against Sunlighten's flagship mPulse line, which is quote-gated and generally starts around $7,000, the Equinox gives up some of the deepest customization (Sunlighten's PulseIQ separates near, mid, and far IR into independently controllable channels) and the integrated tablet interface. Both Equinox sizes come in under Sunlighten's typical pricing, and Sun Home publishes a numerical, third-party EMF figure where Sunlighten's product page stays qualitative.

Against entry-tier Amazon cabins in the $1,800–$2,800 range, the Equinox is playing a different game. The Amazon cabins use thinner wood, FIR-only heaters, shorter warranties, and unspecified EMF. The price gap reflects a real spec gap, not a brand premium.

Against the Therasage Thera360 Plus portable at $1,428, the cabin form factor is the relevant comparison rather than the spec sheet. The Equinox is a permanent room-occupying installation. The Thera360 stows under a bed. Buyers who can host a fixed cabin should buy one; renters and apartment dwellers should not.

Who this is for

Homeowners shopping the premium infrared tier who specifically value the published EMF/ELF specs, the eucalyptus interior, and the 7-year warranty are the natural buyer profile. Couples are a particularly clean fit for the 2-person: the bench accommodates both users, the install requirement is one-time, and the operating cost is roughly the same as a single-user session. A household of three is the case for the 3-person, as is a couple who want more room to spread out.

The Equinox also makes sense for buyers stepping up from a portable infrared booth who want the full-cabin experience without paying Sunlighten flagship pricing. If you specifically want red light therapy built into the cabin, Sun Home's step-up model adds it. See our Sun Home Eclipse review for whether that upgrade is worth the premium.

Who should skip it

• Renters and apartment dwellers. The 20A install gets messy with landlord approval. The Therasage Thera360 Plus is the better category for non-permanent setups.
• Households of four or more. The 3-person raises the cap to three; a family of four or more will outgrow either Equinox and should look at a larger or outdoor cabin.
• Traditional sauna purists. Infrared and traditional are different products with different experiences. If löyly is what you want, no infrared cabin delivers it, including this one. See our infrared vs traditional comparison for the full picture.
• Buyers without a path to a 20A circuit. If you cannot get an electrician quote or your panel is at capacity, the Equinox is the wrong fit for your install constraints regardless of every other spec.

The bottom line

Sun Home built the Equinox to be the premium infrared cabin where the published specs match the marketing language. Every meaningful spec it claims is verifiable on the product page or in third-party measurement reports. The EMF shielding is the clearest differentiator at the price; the eucalyptus wood and the 7-year warranty deepen the case. Pick the size by how many people share it: the 2-person for one or two, the 3-person when a third joins or you want the room. The single thing that catches buyers off guard is the 20A circuit, and it's the same on both sizes. Handle that conversation before ordering and the rest of the purchase is one of the cleaner experiences in the category.
