We didn’t choose these models because they’re from competing brands. We chose them because they’re two of the very few full-spectrum infrared saunas that can genuinely exceed 160°F.
Finnmark FD-2 and Sun Home Equinox are two of the only specific models that can push past 160°F on standard household power — most infrared saunas plateau under 140°F at 110V, full stop.
That’s the real reason to put these two side by side in a Finnmark vs Sun Home comparison: if you specifically want high heat without commercial-grade electrical work, this is the short list. Note this comparison is between the FD-2 and the Equinox specifically — Finnmark also makes a separate Trinity Hybrid line that runs hotter using a traditional heater, covered briefly below. The two get there differently — Finnmark on a standard 15A outlet, Sun Home needing a dedicated 20A circuit — and from there it comes down to which tradeoffs fit your situation. Here’s how to tell which one’s for you.
Why Compare These Two Specifically?
For scale: budget-friendly brands like JNH top out around 140°F, and Dynamic tends to land closer to 130–135°F — both well under what Finnmark and Sun Home reach on the exact same residential power. If high heat is the whole point of buying a sauna, those budget brands aren’t really in the running.

The 170°F Claim: Does It Actually Matter?
Finnmark wins on paper here — 170°F vs. 165°F. That number is real, confirmed by multiple retailers, not just Finnmark’s own marketing.
But here’s the decision that actually matters: most people run full-spectrum sessions at 130–150°F regardless of the max setting. Unless you specifically plan to max out the dial every single time, this 5-degree gap won’t change your experience. Don’t let it break the tie for you.
One thing worth knowing if you want it hotter than either of these: Finnmark also sells a separate Trinity Hybrid line (FD-4, FD-5) that pairs the same 170°F infrared system with a traditional Harvia heater and rocks — running noticeably hotter than infrared alone once the traditional heater kicks in. That’s a different product from the FD-2 this article compares, and an important catch: the traditional heater needs to be hardwired by a licensed electrician, on its own 240V line. So the “no electrician needed” pitch only applies to the infrared-only FD-2, not the Hybrid models.
What the EMF numbers actually mean for your decision: Both numbers are real and lab-tested. This isn’t a situation where one brand made something up — Finnmark’s 1.17mG and Sun Home’s 0.3–0.5mG both come from accredited, named labs with real reports behind them.
The difference is age. Finnmark’s test is from December 2019 — six years old. Sun Home’s Vitatech report is from January 2025. If “how current is the data” matters to you, that decides it: Sun Home wins on recency. If you just want confirmation both are legitimately tested and not just marketing talk, you already have your answer — yes, both are.
PRL take: One brand’s EMF number is from when the iPhone 11 was new. The other’s is from last year. For a decision today, recent data tells you more about what you’d actually get.
Same Voltage, Different Amperage — This Is the Real Split
Both saunas run on standard 110–120V household power — neither needs commercial-grade electrical service. But getting to 160°F+ on that voltage takes more current, and the two brands solve that differently.
Finnmark’s FD-2 does it on a standard 120V/15A outlet — the kind already in most rooms. Plug it in, done. The Sun Home Equinox needs a dedicated 120V/20A circuit to hit its 165°F ceiling, which in an older home can mean an electrician visit before the sauna even arrives.
If you’re in new construction or already have a 20A outlet free, this is a non-issue. If you’re retrofitting an older house, budget an extra $150–$400 for an electrician on top of the sauna’s sticker price — something neither brand’s marketing mentions.
Warranty: What 10 Years vs. 7 Actually Buys You
Finnmark’s 10-year warranty includes a lifetime guarantee specifically on the Spectrum Plus heaters — the part most likely to fail after years of regular use. Sun Home’s Equinox carries 7 years on cabinetry and heaters, plus 3 years on the digital controls specifically. For occasional users, this gap may never matter. For anyone planning to use a sauna 4–5 times a week for a decade-plus, the heater being covered for life is the kind of detail that only matters the day something actually breaks — but it matters a lot that day.
That long-haul use case isn’t hypothetical. One verified FD-2 owner bought theirs in 2022, took a year-and-a-half break, then came back to using it 4–5 times a week — calling it “the best health investment I have ever made.” That’s the kind of multi-year relationship a warranty needs to actually hold up for.
Build Quality: Cedar vs. Eucalyptus, Bolts vs. Magnets
This is the part most comparisons skip, and it actually changes the day-to-day experience. Finnmark builds the FD-2 interior from antimicrobial Western Canadian Red Cedar — the classic sauna look and scent, naturally moisture-resistant. Sun Home uses kiln-dried eucalyptus instead: denser, harder, lower natural VOC off-gassing, but without cedar’s aromatic smell. Neither is “better” — it’s a preference call, and if you specifically want that traditional cedar aroma, Finnmark gives you that and Sun Home doesn’t. For a deeper look at how the eucalyptus build holds up, see our full Sun Home Equinox review.
Assembly is a bigger practical gap. Finnmark uses a standard panel-locking system — heavy panels that genuinely need two people to latch into place. Sun Home’s Magne-Seal system uses magnetic panels that snap together without tools; Sun Home’s own listing says 30–60 minutes, though independent assembly reports run closer to 45 minutes to two hours depending on how many hands you have helping. Either way, it’s faster and less physical than Finnmark’s traditional build.
One more data point worth knowing: Sun Home publishes AIHA-accredited VOC testing (27 µg/m³) for the Equinox — a separate certification from the EMF testing, covering off-gassing rather than electromagnetic field. Finnmark’s marketing doesn’t mention VOC testing for the FD-2 at all. That’s not proof Finnmark has a VOC problem — it just means Sun Home is the only one of the two publishing that particular number.
The Availability Problem Nobody’s Talking About
As of this writing, Finnmark FD-2 units are backordered at multiple authorized dealers. One retailer’s listing shows pre-order only, with shipping pushed to late August 2026, and another lists the FD-2 as unavailable outright due to demand, pointing customers toward a different model instead. This isn’t one retailer having a bad week — it’s showing up across more than one authorized seller, which suggests a factory-level supply issue rather than a single dealer’s stock problem.
That changes the comparison for anyone buying now rather than researching for later. The Sun Home Equinox is shipping normally. If you need a sauna this summer, the spec sheet might not be the deciding factor — what’s actually available to ship is.
Who Should Buy Which
| Choose Finnmark FD-2 If You’re… | Choose Sun Home Equinox If You’re… |
|---|---|
| Set on the highest available temperature ceiling | Buying now and need it to actually ship this summer |
| Stuck with a standard 15A outlet and don’t want an electrician | Prioritizing the most recent EMF verification available |
| Willing to wait into late summer for delivery | OK running a dedicated 20A circuit, or already have one |
| Want the longer warranty (10 years vs. 7) | Want a brand actively publishing fresh third-party test data |
| Want the traditional cedar scent and look | Want faster, tool-free assembly and don’t mind skipping the cedar aroma |
Editorial Integrity Note
We have not physically tested either sauna. Specs are cross-referenced from each brand’s official site, the original NTS and Vitatech test reports, and multiple authorized retailer listings as of June 2026. Availability information comes from public retailer listings, not a direct statement from Finnmark — if you’re closer to a purchase, confirm current stock directly with a dealer before assuming either situation has changed.
PRL Verdict: Finnmark vs Sun Home
Choose Finnmark if: you want the highest ceiling temperature, a standard outlet is a hard requirement, and you can wait out the current backorder.
Choose Sun Home if: you want a sauna that ships now and EMF data from the current decade, and a 20A circuit isn’t a dealbreaker.
Bottom line: In the Finnmark vs Sun Home decision, both brands have legitimate third-party EMF testing — this isn’t a “one brand lies” situation like some budget products. The real differences are recency of that data, electrical requirements, and right now, whether you can actually get one delivered. For most buyers in June 2026, that last point may decide it before the spec sheet does.

FAQ
Finnmark vs Sun Home: which is better for EMF?
Sun Home’s data is more current; Finnmark’s is older but still legitimate.
Finnmark’s FD-2 measured 1.17mG via an accredited lab (NTS) in December 2019. Sun Home’s Equinox measured 0.3–0.5mG via Vitatech Electromagnetics in January 2025. Both are real, accredited tests — the difference is six years of recency, not one brand faking data.
Why is the Finnmark FD-2 sold out or backordered?
Multiple authorized dealers report factory-level supply delays.
As of June 2026, more than one authorized Finnmark retailer lists the FD-2 as pre-order only (shipping late August) or unavailable. This pattern across multiple sellers points to a supply issue at the manufacturer level, not a single store running low.
Does the Sun Home Equinox need special electrical work?
Yes — a dedicated 20A circuit, which the Finnmark FD-2 doesn’t require.
The Equinox needs a 120V/20A dedicated circuit, which can mean hiring an electrician in older homes. The Finnmark FD-2 runs on a standard 120V/15A outlet most rooms already have.
Which sauna runs hotter, Finnmark or Sun Home?
Finnmark, by 5°F — though most sessions don’t use either unit’s max setting.
The FD-2 reaches 170°F using combined Spectrum Plus and Spectrum Carbon heaters; the Equinox tops out at 165°F. Most users run full-spectrum sessions in the 130–150°F range regardless of the unit’s ceiling, so the 5-degree gap rarely shows up in actual use.
