Quick Answer: Sun Home positions itself as the budget alternative to Sunlighten, but on October 2026 shop prices that never actually happens. The entry far-infrared tier is an exact tie — Solstice 1-Person and Signature I both sell for $4,999 — and above it Sunlighten is cheaper size for size: the full-spectrum Amplify II ($5,799-$5,999) undercuts Sun Home’s Equinox 2-Person ($6,099), and Sunlighten’s 2-person red-light Amplify RED II ($7,699) undercuts Sun Home’s Eclipse 2-Person ($9,999) by $2,300. Pricing is from each brand’s own US shop, checked October 29, 2026.
Updated October 29, 2026: re-priced every tier from both brands’ current US shops (Sun Home’s Solstice dropped to $4,999; Sunlighten’s Signature I is $4,999, Amplify II $5,799-$5,999, Solo dome $1,999). We also corrected the red-light matchup: this page previously compared the Eclipse 2-Person with the mPulse Aspire at $7,499, but Sunlighten’s own product page lists the Aspire as a 1-person sauna. The like-for-like 2-person rivals are Sunlighten’s newer Amplify RED II ($7,699) and the mPulse Believe ($8,899).
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 | Infrared sauna blanket, $499 (no dome) | Solo Dome Chromo, $1,999 | Different products |
| Far-infrared only, 1-person | Solstice 1-Person, $4,999 | Signature I, $4,999 | Exact tie |
| Far-infrared only, 2-person | Solstice 2-Person, $5,599 | Signature II, $5,499 | Sunlighten by $100 |
| Full-spectrum, no red light, 2-person | Equinox 2-Person, $6,099 | Amplify II, $5,799-$5,999 | Sunlighten by $100-$300 |
| Full-spectrum + red light, 2-person | Eclipse 2-Person, $9,999 | Amplify RED II, $7,699 / mPulse Believe, $8,899 | Sunlighten by $1,100-$2,300 |
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.
- Now $4,999 (regular $5,599) — exactly the same price as Sunlighten's Signature I at the same far-infrared-only tier, not the clear undercut Sun Home's positioning implies.
At this bottom tier, per each brand’s own US shop on October 29, 2026, Sun Home’s Solstice 1-Person and Sunlighten’s Signature I both sell for $4,999, and at 2-person size Sunlighten’s Signature II ($5,499) is $100 under Sun Home’s Solstice 2-Person ($5,599). 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 sells for $6,099 ($6,799 regular), while Sunlighten’s Amplify II is $5,799 in basswood or $5,999 in eucalyptus — a $100-$300 gap in Sunlighten’s favor, even though both are 2-person full-spectrum cabins with no red light therapy included. At 3-person size the gap closes to nothing or $200 (Amplify III $6,799-$6,999 vs. Equinox 3-Person $6,999). Sun Home’s Equinox runs on a 120V/20A circuit, while Sunlighten lists Amplify as 120V or 240V depending on the model, so confirm your circuit before treating the sticker gap as the real difference.
The flagship tier: the biggest gap of all
Sunlighten Amplify RED II 2-Person Red Light Sauna
- Full-spectrum infrared plus integrated visible red and near-infrared light; 240V circuit required on every Amplify RED size.
- $2,300 less than Sun Home's Eclipse 2-Person ($9,999); the mPulse Believe, Sunlighten's other 2-person red-light cabin, is listed at $8,899.
- Sunlighten publishes no red light wavelength or output figure; Sun Home publishes 650nm + 850nm and 180-250 mW/cm² at 6 inches for the Eclipse.
Sun Home’s Eclipse 2-Person ($9,999) and Sunlighten’s Amplify RED II ($7,699) are the closest apples-to-apples matchup between the brands: both are 2-person, full-spectrum cabins with built-in red light. Sunlighten wins on price by $2,300, or by $1,100 if you want its PulseIQ-based mPulse Believe ($8,899) instead. Don’t compare the Eclipse with the mPulse Aspire: Sunlighten’s own product page lists the Aspire as a 1-person sauna. Eclipse’s real edges at this tier are service and documentation, not heat: Sun Home dispatches a technician to your home for any warranty issue on Eclipse, Luminar, and Pod models, and it publishes the Eclipse’s red light wavelengths and output, which Sunlighten doesn’t. Wiring differs too — the Eclipse 2-Person uses a 120V/30A twist-lock circuit, Amplify RED a 240V circuit. For every red-light cabin compared on published specs, see our best red light sauna guide.
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 at the lowest price — its Amplify II and Amplify RED II undercut Sun Home’s equivalent Equinox and Eclipse 2-person cabins by $100-$300 and $2,300 respectively, and its $1,999 Solo dome has no Sun Home equivalent at all for renters or small spaces. Buy Sun Home if you want the entry-level far-infrared Solstice (an exact tie with Signature I at $4,999) or you value the Eclipse’s technician-dispatch warranty service and published red light specs enough to pay its $2,300 premium over Amplify RED II.
