Quick Answer: Sun Home positions itself as the budget alternative to Sunlighten, and that holds true only at the cheapest far-infrared tier — Solstice ($5,299) versus Signature ($5,099), essentially a wash. Match the brands feature-for-feature at higher tiers and the story flips: Sunlighten’s full-spectrum Amplify ($5,799) undercuts Sun Home’s Equinox ($6,099), and Sunlighten’s red-light mPulse Aspire ($7,499) undercuts Sun Home’s Eclipse ($9,999) by roughly $2,500. Pricing above is per each brand’s own 2026 shop listings, verified September 2026.
Both are direct-to-consumer infrared sauna brands with lineups split into multiple lines by wavelength coverage, so a fair comparison means matching tier to tier — far-infrared to far-infrared, full-spectrum to full-spectrum, red-light to red-light — not just picking whichever entry price sounds lower.
Sun Home vs. Sunlighten, tier by tier
| Tier | Sun Home | Sunlighten | Cheaper |
|---|---|---|---|
| Portable / entry | None | Solo dome, $1,899 | Sunlighten (no Sun Home equivalent) |
| Far-infrared only | Solstice, $5,299 | Signature, $5,099-$5,599 | Roughly tied |
| Full-spectrum, no red light | Equinox, $6,099-$6,599 | Amplify, $5,799 | Sunlighten by ~$300 |
| Full-spectrum + red light | Eclipse, $9,999 | mPulse Aspire, $7,499 | Sunlighten by ~$2,500 |
The entry tier: Solstice vs. Signature is nearly a tie
Sun Home Solstice 1-Person Far Infrared Sauna
- Eight to ten wall-mounted far-infrared panels, kiln-dried eucalyptus, built-in chromotherapy and Bluetooth audio.
- $200 more than Sunlighten's Signature I ($5,099) at the same far-infrared-only tier — a near-wash, not the clear undercut Sun Home's positioning implies.

At this bottom tier, per each brand’s own current 2026 shop pricing, Sun Home’s Solstice ($5,299) actually runs about $200 above Sunlighten’s Signature I ($5,099), though Sunlighten’s larger 2-person Signature II ($5,599) does cost more than Solstice. Close enough either way that far-infrared shoppers should decide on warranty service and build details rather than price alone — see our best Sun Home sauna and best Sunlighten sauna breakdowns for the rest of each brand’s lineup.
The full-spectrum tier: Sunlighten actually wins on price
This is where Sun Home’s “budget alternative” positioning breaks down. Sun Home’s Equinox 2-Person lists at $6,099 on sale ($6,599 regular), while Sunlighten’s Amplify II and III both list at $5,799 — a roughly $300 gap in Sunlighten’s favor, even though both are 2-3 person full-spectrum cabins with no red light therapy included. Sun Home’s Equinox does run on a standard 120V/20A circuit, which is simpler to install than some higher-tier full-spectrum cabins, but on sticker price alone, Sunlighten’s Amplify is the cheaper full-spectrum buy.
The flagship tier: the biggest gap of all
Sunlighten mPulse Aspire 2-Person Full Spectrum Sauna
- Full-spectrum near/mid/far infrared plus red light therapy, starting price per Sunlighten's own current shop listing.
- About $2,500 less than Sun Home's comparably-equipped Eclipse 2-Person ($9,999) despite matching wavelength and red-light coverage.
Sun Home’s Eclipse 2-Person ($9,999) and Sunlighten’s mPulse Aspire ($7,499) are the closest apples-to-apples matchup between the brands: both are 2-person, full-spectrum, red-light-equipped flagship cabins. Sunlighten wins on price by roughly $2,500. Eclipse’s one real edge at this tier is service, not heat: Sun Home dispatches a technician to your home for any warranty issue on Eclipse, Luminar, and Pod models, rather than the self-service repair path more common in the category. Whether that white-glove service is worth a $2,500 premium depends on how much you value not troubleshooting a sauna yourself.
Warranty: close, and neither beats Clearlight
Sun Home’s residential warranty covers cabinetry and heaters for a limited lifetime (rated to a 7-year expected component life) and controls for 3 years. Sunlighten’s is similarly tiered — 7 years on cabinetry/heaters, 3 years on controls, but only 1 year on glass doors and audio. The two are close enough that warranty length shouldn’t be the deciding factor between these two brands specifically; if a genuinely stronger warranty matters more than brand, our Sunlighten vs. Clearlight comparison covers Clearlight’s flat lifetime-on-everything coverage, which beats both.
The bottom line
Buy Sunlighten if you want full-spectrum or red-light heat — its Amplify and mPulse Aspire lines undercut Sun Home’s equivalent Equinox and Eclipse tiers by $300-$2,500 despite matching wavelength coverage, and its $1,899 Solo dome has no Sun Home equivalent at all for renters or small spaces. Buy Sun Home if you specifically want the entry-level far-infrared Solstice (essentially tied with Signature on price) or you value Eclipse’s white-glove technician-dispatch warranty service enough to pay its $2,500 premium over mPulse Aspire.
