Sun Home vs Sunlighten: Which Infrared Sauna Should You Buy?
Sun Home and Sunlighten compared on current price, full-spectrum models, electrical requirements, published testing, warranty, returns and ownership risk.
Comparison
Quick answer: Choose Sun Home Equinox if you want a publicly priced $6,099 full-spectrum two-person cabin, a 120V/20A install path and published third-party VOC and EMF documents. Choose Sunlighten Signature if far-infrared is enough and its $5,099-$5,599 published price fits, or consider mPulse only after getting the full price, electrical, delivery and control-replacement terms in writing. Sun Home is our current overall pick, with the shorter company track record as its main tradeoff.
Best for
US buyers comparing premium indoor infrared cabins from Sun Home and Sunlighten.
Wrong fit
Buyers who want a traditional high-temperature Finnish sauna or an outdoor cabin.
Tradeoff
Sun Home gives clearer price and test documentation; Sunlighten gives a longer brand track record and broader consultation-led product story.
Sun Home and Sunlighten sell premium infrared saunas in overlapping price bands, but the buying experience is different. Sun Home publishes prices, a model-level electrical path and third-party documents. Sunlighten publishes prices for Signature and Solo, while mPulse and Amplify still require a consultation.
Our current pick is Sun Home Equinox for the buyer who wants full-spectrum infrared with evidence and price visible before a sales call. Sunlighten Signature remains a credible far-infrared alternative, and mPulse only makes sense after a complete written quote.
Disclosure: Sun Home paid for a May 2026 launch sponsorship. We kept editorial control, and the sponsorship did not buy this verdict. See our editorial policy.

Where Sun Home wins
1. A full-spectrum price you can see
The Equinox 2P is currently listed from $6,099. That creates a clean decision point: compare the exact delivered cost with Sunlighten's quoted full-spectrum mPulse or Amplify, not with a far-infrared Signature cabin that performs a different job.
The Equinox also publishes a 120V/20A electrical path. That can avoid the cost and scheduling of a 240V circuit when the home's existing dedicated circuit is suitable. Have an electrician confirm the outlet and circuit before delivery rather than assuming any standard receptacle is ready.
2. Better public evidence before checkout
Sun Home publishes an April 2026 VOC report from an AIHA-LAP-accredited laboratory using EPA Method TO-15, with a reported 27 micrograms per cubic meter total VOC result. It also publishes a Vitatech seated-position magnetic-field reading of 0.5 mG.
Those documents do not prove every health claim, and EMF readings depend on measurement location and method. They are still more useful than an unsourced "low EMF" badge because a buyer can inspect the lab, method, date and result.
3. Simpler buying path
The price, model and electrical requirement are visible without entering a sales funnel. That does not make delivery, returns or warranty effortless. It makes the initial comparison less opaque.
Where Sunlighten wins
1. Longer brand history
Sunlighten has operated since 1999, while Sun Home was founded in 2021. A longer history is not a product test, but it gives Sunlighten a larger installed base and more years of owner experience to inspect. Buyers who prioritize company longevity may accept the consultation process for that reason.
2. A lower-priced published far-infrared cabin
Sunlighten's US shop lists Signature I at $5,099 and Signature II at $5,599 under current sale pricing, with free contiguous-US shipping shown at the July 2026 check. If far-infrared is the actual requirement, Signature II can cost less than Sun Home Equinox.
Do not compare those stickers without technology and scope. Equinox is full-spectrum. Signature is far-infrared. The correct question is whether you will use the additional spectrum and controls, not which product page has more wavelength language.
3. More product paths
Sunlighten offers Solo portable, Signature far-infrared, Amplify full-spectrum, mPulse with its PulseIQ control layer and custom installations. That breadth is useful when a buyer has an unusual space or wants a consultation-led solution.
The cost is complexity. mPulse and Amplify prices are not published, and mPulse makes an embedded control interface central to the experience. Put replacement cost, controls warranty and manual fallback behavior in writing before paying.

Sunlighten's own shop is the source of the Solo and Signature prices. The mPulse and Amplify ranges come from a third-party 2026 price guide and are weaker evidence. They are included only to set the scale of the sales call; your written quote is the number.
Warranty: nearly the same headline, same missing-cost question
Both published residential warranty structures resolve to roughly seven years on cabin/heaters, three years on controls and one year on selected glass, LED or audio components. Both are non-transferable, and neither should be described as seven years of free ownership.
Ask each seller:
Who diagnoses the problem after 90 days?
Who pays labor, travel and shipping for parts?
What is the control or tablet replacement cost outside warranty?
Does the sauna still heat if the app or main display fails?
Which maintenance, electrical or placement condition can void coverage?
The sauna warranty comparison shows why a long headline can still leave the expensive service line with the owner.
The tradeoffs Sun Home buyers should not skip
Sun Home has a shorter ownership record, does not state manufacturing origin on its public site and limits returns once a cabin is assembled. Independent import records connected to its operating entity indicate Chinese OEM production. Country of manufacture is not a reliability verdict, but origin-sensitive buyers should ask for it in writing.
Sun Home's published warranty terms are documents, not our first-hand claims experience. We have not owned the Equinox for years or tested a warranty claim. Price the labor and shipping exposure the same way you would for Sunlighten.
The tradeoffs Sunlighten buyers should not skip
The sales consultation should end in a written line-item quote, not a verbal discount. Confirm model, delivery method, white-glove fee, circuit, accessories, cancellation window and return freight before paying.
For mPulse, ask about the embedded control layer specifically. Owner complaints and independent reviews report tablet or control failures and slower heat-up than some marketing expectations. These reports are not a measured failure rate, so use them as pre-purchase questions rather than proof that every unit fails.
Our verdict
Buy Sun Home Equinox when you want full-spectrum infrared, a clear $6,099 starting price, a 120V/20A install path and inspectable VOC and EMF documents. It is our current pick for that buyer.
Buy Sunlighten Signature when far-infrared is enough, the published $5,099-to-$5,599 price fits and the older brand history matters. Consider mPulse or Amplify only when the written quote and control-service terms beat Equinox on a feature you will actually use.
For a two-person full-spectrum buyer, Sun Home Equinox is our current pick because price, 120V/20A installation and third-party documents are visible. Sunlighten can be better for buyers who want its older brand history, Signature far-infrared pricing or a specific consultation-led model.
Which is cheaper, Sun Home or Sunlighten?
Sunlighten Signature I and II are currently cheaper than Sun Home Equinox, but they are far-infrared rather than full-spectrum. Sunlighten mPulse and Amplify require quotes, so a direct full-spectrum price comparison needs a written proposal.
Which has the better warranty?
The residential headlines are similar. The meaningful comparison is labor, shipping, diagnostics, controls and transferability after 90 days. Neither should be bought on the seven-year phrase alone.
Has Sauna Guide tested these saunas?
We have not completed a long-term ownership test of either cabin or a warranty claim. The comparison uses current manufacturer documents, published laboratory material, price checks, independent records and owner reports labeled by evidence type.
These guides are built from manufacturer documentation, public specifications, primary research where health claims matter, and repeated buyer questions that show up in real ownership and installation decisions.
Manufacturer responses can clarify pricing bands, warranty terms, support footprint, or common mistakes. They do not move a page up the shortlist on their own.
