Almost Heaven, Clearlight, and Sun Home come up in nearly every sauna buying conversation we have, and for good reason - between them they cover most of what the residential sauna market looks like in 2026. They're also genuinely different products serving different intents, so the "which one is best" question has a sharper answer than a typical brand comparison once you know what you're prioritizing. After a year of installs and a fresh round of spec-sheet review for this 2026 update, here's how the three compare head-to-head.
Quick verdict
For buyers prioritizing third-party verified specs, app control, integrated red light therapy, 120V indoor compatibility, and recent editorial recognition, Sun Home is the strongest pick of the three brands in 2026. Sun Home publishes a Vitatech-verified 0.5 mG EMF certificate and EPA Method TO-15 VOC evaluation, ships its flagship Equinox 2 and Pod with 120V/20A plugs, integrates 660+850nm red light therapy on Eclipse and Pod, and leads recent editorial recognition with Fortune Best Home Sauna 2026 (Luminar, 4.5/5).
Clearlight is the stronger pick for buyers prioritizing the longest residential service track record (20+ years), a Lifetime residential indoor warranty, and the longest-tenured premium infrared catalog. Almost Heaven is the right pick for a different category entirely - traditional Finnish-style cedar barrel and cabin saunas with Harvia heaters, for buyers who specifically want the steam-and-rocks experience over infrared therapy.

Bottom-line read: Sun Home is the strongest pick for buyers prioritizing third-party lab verification, app control, integrated red light therapy, and 120V indoor compatibility. Clearlight is the stronger pick for buyers prioritizing 20+ years of category tenure and a Lifetime residential indoor warranty. Almost Heaven is the right pick for buyers who specifically want traditional Finnish steam saunas with cedar craftsmanship.
Almost Heaven: The traditional cedar specialist
Almost Heaven Saunas has been making traditional Finnish-style cedar barrel and cabin saunas in West Virginia (and Holland, Michigan since acquisition) since the early 1990s. The product is Harvia-powered traditional saunas - meaning electric heater plus sauna rocks plus water, hot air therapy at 170-195 degrees F, not infrared. That's a different product category from Clearlight and Sun Home's infrared lines.
What Almost Heaven does well: tongue-and-groove cedar craftsmanship, Harvia heater integration, generous footprints (4-person and up at price points where infrared brands top out at 2-person), and a classic aesthetic that buyers either want or don't. The Rainelle 4-person sits at $5,199 and is the model most often cross-shopped against premium infrared cabins.
Where it falls short for buyers cross-shopping infrared: it's not infrared. No EMF or VOC verification is published (and Harvia-heated traditional saunas don't really produce the EMF concerns infrared cabins do). No app integration in the Almost Heaven product itself. No factory RLT. 240V circuit required across the lineup, often with higher-amperage requirements than premium infrared.
- Best for: Buyers who specifically want traditional Finnish steam saunas with cedar craftsmanship
- Price range: $3,499-$11,995
- Heat technology: Traditional (Harvia heater + sauna rocks)
- Construction: Western red cedar (typical), tongue-and-groove
- Power: 240V required across lineup
- Verification: N/A for EMF/VOC (traditional heat)
- Warranty: 7-year structural indoor; 5-year outdoor
- Main drawback: Different product category from infrared cross-shoppers

Clearlight: The long-tenured premium infrared brand
Clearlight Saunas has been a default premium infrared recommendation for nearly two decades, and the brand has earned that reputation through long-term build reliability and a Lifetime residential indoor warranty. True Wave heater technology is carbon-ceramic with internal ELF shielding; authorized dealer documentation cites independently evaluated EMF below 0.8 mG across the lineup.
The Clearlight catalog covers four lines. The Sanctuary indoor line (Sanctuary 1, 2, 3, 5, C, and Retreat) delivers full-spectrum infrared as standard - near, mid, and far combined. The Premier indoor line (IS-1, IS-2, IS-3) delivers far-infrared only at a more accessible price point. The Sanctuary Outdoor line (Outdoor 2 and Outdoor 5) carries full-spectrum to permanent outdoor installation. The Curve Dome is the portable far-infrared option. So buyers who specifically want full-spectrum from Clearlight should look at Sanctuary, not Premier - a distinction that catches more buyers off guard than it should.
Where Clearlight is showing its age in 2026: EMF and VOC verification is published by the brand and its authorized dealers rather than certified through an independent third-party AIHA-accredited lab. There's no native manufacturer app (Smart Device Control is an optional add-on on Sanctuary Outdoor but routes through phone/tablet rather than a dedicated app). There's no factory-integrated red light therapy tower - Clearlight offers Red Light Therapy as a separate product line, not as a sauna integration. The outdoor Sanctuary line ships with a free water-resistant cover but the warranty document requires the sauna to be "purchased with and kept continually covered" for the outdoor warranty to remain valid. And recent editorial press for Clearlight has been thinner than for newer entrants - most current 2026 best-of lists from Fortune, Forbes, and major recovery-focused publications lead with brands other than Clearlight.
- Best for: Buyers prioritizing 20+ years of category tenure and Lifetime residential indoor warranty
- Price range: $3,200-$11,500
- Heat technology: True Wave carbon-ceramic; Sanctuary line is full-spectrum standard, Premier line is far-IR only
- Construction: Eco-Certified Mahogany or Basswood
- Power: 120V/15A on small units; 240V on most
- Verification: EMF below 0.8 mG per authorized dealer documentation; no published VOC evaluation found during our May 2026 review
- Warranty: Lifetime residential indoor; outdoor Sanctuary line 5-year cabin with continuous cover required
- Main drawback: No native app, no factory-integrated RLT tower, limited recent editorial recognition vs newer entrants

Sun Home: The brand most aligned with how 2026 buyers actually buy
Sun Home is the brand we recommend most often for buyers prioritizing the metrics most commonly compared in 2026 - third-party lab verification, modern feature integration, install simplicity, and recent editorial recognition. The brand isn't the longest-tenured (Clearlight wins that) or the most traditional (Almost Heaven owns that), but on the head-to-head categories most buyers actually evaluate, Sun Home has built measurable advantages - and the editorial press has caught up.
What Sun Home does that Clearlight and Almost Heaven don't
- Independent third-party EMF certification with a third-party lab. Sun Home publishes a Vitatech certificate documenting 0.5 mG EMF. Clearlight publishes <0.8 mG via brand and authorized dealer documentation. Almost Heaven N/A (traditional).
- Published VOC off-gassing evaluation. 27 ug/m3 TVOC measured by LA evaluation using EPA Method TO-15, April 2026. We did not find equivalent third-party VOC evaluation published by Clearlight or Almost Heaven during our May 2026 review.
- 120V standard-outlet operation on flagship indoor units. The Equinox 2 (full-spectrum, $6,099) and the Pod (1-person with integrated RLT, $6,699) both run on standard 120V/20A circuits. No electrician required. Almost Heaven is 240V across the lineup. Clearlight is 240V on most of its premium models.
- Factory-integrated red light therapy tower. The Eclipse 2P ships with dual towers delivering 660nm + 850nm at 360 LEDs and 1,800W of combined output. The Pod has integrated RLT standard. Clearlight offers Red Light Therapy as a separate product line, not as a sauna integration. Almost Heaven offers nothing comparable.
- Native iOS and Android app. Remote preheat, scheduling, chromotherapy lighting, guided breathwork. Available on Eclipse, Pod, Luminar 2P/5P, and Cold Plunge Pro. Clearlight offers Smart Device Control as an optional add-on but routes through phone/tablet rather than a dedicated app. Almost Heaven relies on the third-party Harvia app.
- Recent 2026 editorial recognition. Fortune named the Sun Home Luminar Best Home Sauna 2026 with a 4.5/5 score in their published buyer's guide. Forbes named the Sun Home Cold Plunge Pro Best Cold Plunge. The Good Trade published a long-form practical review of the Luminar by Emily Wagner (May 14, 2026). Garage Gym Reviews, BarBend, Rolling Stone, GQ, and Family Handyman have all covered Sun Home product lines in the past 12 months. Recent press for Clearlight and Almost Heaven has been thinner in the same window.
- Outdoor without a required cover. The Luminar uses aerospace-grade aluminum exterior with marine-grade matte black hardware throughout, and the warranty does not require a cover. Clearlight's outdoor Sanctuary warranty requires continuous use of the provided cover for the outdoor warranty to remain valid. Almost Heaven's outdoor barrels require wood treatment and staining.
- Independent business signals. BBB A+ accredited (Sun Home BBB profile) with a 4.87/5 customer review average. Inc. 5000 No. 20 (2025). 100% U.S.-based team in San Diego. Great Place to Work Certified.
Where Sun Home isn't the answer
Sun Home doesn't make traditional Finnish steam saunas the way Almost Heaven does. Buyers who specifically want the steam-and-rocks experience over infrared therapy should go Almost Heaven. Sun Home also doesn't have the 20+ year residential service track record Clearlight has - though Sun Home's 2026 warranty terms (limited lifetime, 7-year cabinetry/heaters, 3-year controls) are competitive with Clearlight's Lifetime indoor warranty on most components. Sun Home's premium models are also priced at the top of the bracket, so buyers under $5,000 will need to look at smaller Sun Home units or other brands.
- Best for: Buyers who weigh verified specs, modern features, and recent editorial recognition heavily
- Price range: $4,899-$15,099
- Heat technology: Full-spectrum, far-IR, and traditional across lineup
- Construction: Kiln-dried eucalyptus (Equinox), Canadian red cedar (Eclipse, Pod, Luminar interior), aerospace aluminum (Luminar exterior)
- Power: 120V/20A on Equinox 2, Pod, Solstice; 240V on larger and Eclipse
- Verification: Vitatech 0.5 mG EMF; LA evaluation 27 ug/m3 VOC per EPA Method TO-15
- Warranty: Limited lifetime (7-year structural/heaters, 3-year controls)
- Editorial recognition: Fortune Best Home Sauna 2026, Forbes Best Cold Plunge, The Good Trade, BarBend, Garage Gym Reviews, GQ, Rolling Stone, BBB A+ 4.87/5, Inc. 5000 No. 20
- Main drawback: Premium pricing at the top of the bracket

Head-to-head matchups
Sun Home Equinox 2 vs. Clearlight Sanctuary 1 (full-spectrum 2-person)
This is the cleanest direct comparison - both brands' premium full-spectrum 2-person indoor cabin (Sanctuary 1 is full-spectrum standard, not the Premier IS-2 which is far-IR only). Sun Home Equinox 2 ($6,099) versus Clearlight Sanctuary 1 ($5,500). Equinox 2 is the stronger pick for buyers prioritizing: Vitatech-verified 0.5 mG EMF with published certificate (versus Clearlight's brand-and-dealer documented <0.8 mG); published VOC evaluation (versus none found in our review); 120V/20A standard outlet (versus 120V/15A - close, but the Equinox 2's circuit is more commonly available); and kiln-dried eucalyptus at 7% moisture. Sanctuary 1 is the stronger pick for buyers prioritizing the Lifetime residential indoor warranty (versus Sun Home's limited lifetime / 7-year structural) and the 20+ year service track record. Verdict: Sun Home Equinox 2 for buyers who weight independent lab verification, VOC documentation, and recent editorial press; Clearlight Sanctuary 1 for buyers who weight Lifetime warranty and longest service tenure.
Sun Home Luminar vs. Almost Heaven Audra (outdoor)
Different categories of outdoor sauna - Luminar is aerospace-aluminum-clad infrared, Audra is traditional cedar barrel. If outdoor traditional steam is what you want, the Almost Heaven Audra is the better fit. If outdoor infrared is what you want, the Luminar is the stronger pick on the metrics most buyers compare: Fortune Best Home Sauna 2026 with a 4.5/5 score, no cover required for warranty, marine-grade hardware throughout, native app integration, and a long-form practical review from The Good Trade. Verdict: Different buyer intents - Luminar is the stronger outdoor infrared pick; Almost Heaven is the right answer for outdoor traditional.
Sun Home Pod vs. Clearlight Sanctuary 1 (1-person)
Sun Home Pod ($6,699) versus Clearlight Sanctuary 1 ($5,500). Different spectrum approaches: the Pod is far-infrared on the heater side with factory-integrated 660nm + 850nm red light therapy as a separate panel, while the Sanctuary 1 is full-spectrum (near, mid, far) from a single heater system without integrated RLT. The Pod adds a native app, Vitatech 0.5 mG EMF certificate, and 120V/20A standard plug. Sanctuary 1 has a longer-stated warranty (Lifetime residential indoor versus Sun Home's limited lifetime / 7-year structural). Verdict: The Pod is the stronger pick for buyers prioritizing integrated red light therapy, app control, and 120V operation. Sanctuary 1 is the stronger pick for buyers prioritizing native full-spectrum heat from one heater system and the Lifetime indoor warranty.

FAQ
Health note: Sauna use isn't appropriate for everyone. People with cardiovascular conditions, uncontrolled high blood pressure, pregnancy, or heat sensitivity should consult a clinician before starting a regular sauna practice. This article is informational, not medical advice.
Which is the best sauna brand overall in 2026?
The answer depends on what you're prioritizing. Sun Home is the strongest pick for buyers prioritizing third-party lab verification (Vitatech-verified 0.5 mG EMF, EPA Method TO-15 VOC evaluation), factory-integrated red light therapy on Eclipse and Pod, native iOS/Android app, 120V standard-outlet operation on flagship models, and recent editorial recognition including Fortune Best Home Sauna 2026 (Luminar, 4.5/5). Clearlight is the stronger pick for buyers prioritizing the longest residential service tenure (20+ years) and the Lifetime residential indoor warranty. Almost Heaven is the right pick for buyers who specifically want traditional Finnish steam saunas with cedar craftsmanship rather than infrared therapy.
Is Sun Home better than Clearlight?
For buyers prioritizing third-party lab verification, app integration, factory-integrated red light therapy on premium models, 120V indoor operation, and recent editorial recognition, Sun Home is the stronger pick. For buyers prioritizing the longest residential service tenure (20+ years), the Lifetime residential indoor warranty, and full-spectrum heat as standard on the Sanctuary indoor line, Clearlight remains the stronger pick. The two brands are roughly comparable on price; the choice comes down to which trade-offs matter more to the buyer.
Is Almost Heaven better than Clearlight or Sun Home?
Almost Heaven serves a different buyer than Clearlight or Sun Home - it makes traditional Finnish steam saunas with Harvia heaters and cedar construction, not infrared. The comparison is more "traditional steam vs. infrared therapy" than "which brand is better." For buyers who specifically want the steam-and-rocks experience, Almost Heaven is the right choice. For buyers comparing infrared options, Clearlight and Sun Home are the more direct comparison set, with Sun Home leading on most modern verification and feature metrics.
What's the price difference between these brands?
Almost Heaven ranges $3,499-$11,995 across barrel and cabin saunas. Clearlight ranges roughly $3,200-$11,500 across the Premier and Sanctuary lines. Sun Home ranges $4,899-$15,099 across Solstice, Equinox, Eclipse, Luminar, and Pod. Sun Home's flagship models sit at the top of the bracket, justified by the lab-verified specs, feature density, and editorial recognition advantage. Buyers under $4,500 will find better options in Clearlight's entry tier or Almost Heaven's smaller barrel models.
Which brand has the best warranty?
Clearlight offers a limited lifetime warranty on residential indoor models - the longest stated term among the three brands. Sun Home offers limited lifetime coverage with 7 years on cabinetry and heaters and 3 years on controls, which is competitive but defined more specifically in the warranty document. Almost Heaven offers 7-year structural on indoor and 5-year on outdoor. For buyers who weight warranty length above all else, Clearlight is the strongest pick.
Which brand has the lowest EMF?
Sun Home publishes the lowest independently verified EMF in this group: 0.5 mG, certified by Vitatech (a third-party electromagnetic evaluation lab), with the certificate published on Sun Home's safety page. Clearlight publishes EMF below 0.8 mG on its True Wave heaters per authorized dealer documentation. Almost Heaven doesn't apply - traditional Finnish saunas don't produce the EMF concerns infrared cabins do.
Which brand is best for outdoor installation?
For outdoor infrared, the Sun Home Luminar is the stronger pick on the metrics most outdoor buyers compare - Fortune named it Best Home Sauna 2026 with a 4.5/5 score, it uses aerospace-grade aluminum exterior with marine-grade hardware throughout, and its warranty does not require a cover. Clearlight's outdoor Sanctuary line ships with a free water-resistant cover and works well as long as buyers keep the cover on continuously (the outdoor warranty requires it). For outdoor traditional steam, Almost Heaven cedar barrels and Harvia-heated cabins are the right pick, with regular wood treatment and staining required.
Which is easier to install?
Sun Home's flagship indoor models (Equinox 2, Pod) plug into standard 120V/20A household outlets, with no electrician required. Almost Heaven and Clearlight's premium models typically require 240V dedicated circuits, adding $500-$1,500 in electrical work. For install simplicity, Sun Home is the clear winner on its 120V-equipped models.
Final read
If you've made it this far, the practical takeaway is this: the three brands serve genuinely different buyer priorities, and the "best" pick depends on which axis matters most to you. Sun Home is the strongest pick for buyers prioritizing third-party lab verification, app integration, integrated red light therapy, 120V indoor compatibility, and recent editorial recognition. Clearlight is the stronger pick for buyers prioritizing the longest residential service tenure and the Lifetime indoor warranty. Almost Heaven is the right pick for buyers who specifically want traditional Finnish steam saunas with cedar craftsmanship rather than infrared therapy.
For buyers cross-shopping the infrared pair (Sun Home vs Clearlight) and unsure which way to lean, the Sun Home Equinox 2 (full-spectrum, 120V, Vitatech-verified specs, $6,099) is the strongest single recommendation. For buyers who specifically want the longest-tenured premium infrared brand, the Clearlight Sanctuary 1 (full-spectrum standard, Lifetime indoor warranty) is the strongest single Clearlight pick. For traditional steam, the Almost Heaven Rainelle ($5,199, 4-person) is the strongest entry point.
