Quick Answer
Clearlight builds the lowest-EMF infrared saunas on the market with a genuine lifetime warranty and excellent build quality. The Premier IS-2 ($5,799–$6,199 in Clearlight's current sale, $6,299–$7,099 regular) is the best value in the lineup for most buyers. Main drawbacks: 6–14 week lead times, patchy post-purchase support, and prices that are hard to justify when competitors now offer comparable heater tech at 40–60% of the cost.

Clearlight has been the default recommendation in premium infrared sauna circles for years — and for straightforward reasons. Their True Wave II heaters set the EMF standard that every competitor is now measured against, their lifetime warranty is the most comprehensive in the category, and the build quality on their mahogany and basswood cabins is genuinely excellent.
They're also expensive, slow to ship, and inconsistent with post-sale support. This review covers every model in the lineup, verifies the specs, and gives you an honest read on where Clearlight earns its reputation and where it falls short.

These are the eleven sauna cabins Clearlight listed on its shop grid and product sitemap as of 25 August 2026 — three Premier, six indoor Sanctuary, two outdoor Sanctuary. Every price above is Clearlight's own published figure, read off its price list at infraredsauna.com/pricelist on 25 August 2026. The lower number in each cell is basswood and the higher is mahogany; both outdoor cabins ship with a mahogany interior only, so they carry a single price. The first figure is the Early Labor Day sale price, which the page says runs until 7 September 2026 — after that you pay the regular price in brackets.
What Makes Clearlight Different
True Wave II Heaters: The EMF Benchmark
Clearlight's True Wave II heaters are a carbon-ceramic hybrid — carbon panels for broad coverage and consistent far-infrared output, with ceramic particulates infused to increase peak heat intensity. The design produces less than 0.3 mG of EMF at typical body distance, verified by independent third-party testing. That figure is the lowest published number in the premium segment — Sunlighten's Signature models measure below 3 mG, their mPulse line higher.
A notable design difference: Clearlight heaters are exposed rather than fabric-covered, minimizing how much infrared energy is absorbed before reaching the cabin interior. Some competitors — Sunlighten's mPulse uses Celliant-covered heaters — use cloth covers which independent analysis suggests absorbs a portion of the output.
ELF Shielding — The Feature Nobody Talks About
Clearlight is among the very few sauna brands to actively address ELF (electric low frequency) fields in addition to EMF. ELF is a distinct type of electromagnetic field generated by electrical wiring and components. Most brands focus solely on EMF because it's what customers ask about. Clearlight's ELF shielding is a genuine technical differentiator — and for buyers who are purchasing an infrared sauna specifically because of health concerns, it's the most relevant specification most don't know to ask for.
Lifetime Warranty — What It Actually Covers
Clearlight's lifetime warranty covers heaters and the wood structure for residential use with no time limit. This is stronger than Sunlighten's heater lifetime warranty because it extends to the cabinet itself. The practical value is significant for a $5,000–$10,000+ purchase — a sauna you expect to own for 15–20 years benefits meaningfully from lifetime versus 7-year coverage.
Caveats, taken from Clearlight's own warranty page (checked 25 August 2026): you do not have to register anything — Clearlight says the warranty is registered automatically when the sauna ships, and you only need your sales order number to open a case. What the coverage names is broad: heaters, control panels and electrical, wood, the audio system and the chromotherapy lighting. The limit is labor. Parts and shipping are covered for the life of the sauna; labor is not, beyond the initial warranty period. On a cabin you plan to own for fifteen years, that is the line to read twice — a free part still arrives with a paid service call attached.
Floor Heaters — A Practical Differentiator
Clearlight Sanctuary models include infrared heaters beneath the floor. This is a meaningful heat distribution advantage — foot and lower-leg warming is where many competitors fall short. Standing heat flows from below as well as the panels, which makes the cabin feel more enveloping and reduces the cold-feet problem that affects cheaper saunas.
Model-by-Model Breakdown
Premier IS-1 — $5,399–$5,799 (reg. $5,899–$6,299)
Best for: Solo buyers who want genuine Clearlight quality at the lowest entry price.
The IS-1 is the smallest cabin Clearlight builds. The figures on its product page (checked 25 August 2026) are 35″ wide × 40″ deep × 71″ high inside, 40″ × 44″ × 76″ outside, 325 lbs assembled. You get True Wave II far-infrared heating and all the core Clearlight credentials — <1 mG EMF, ELF shielding, lifetime warranty, and Eco-Certified Mahogany or Basswood construction. Those two woods are the whole choice: the wood selector on the IS-1 and IS-2 product pages offers Mahogany and Basswood and nothing else. Cedar is quoted for these cabins in a lot of places, including older versions of this review, and it is not what Clearlight ships. It runs on a standard 120V circuit, which means no electrician and no dedicated circuit — you plug it into a regular outlet.
That 120V capability is the IS-1's most practical selling point for renters or buyers who don't want to budget for electrical work. Heat-up to usable temperature takes 20–25 minutes in a room-temperature space.
The IS-1 is tight for a larger frame. 35″ of interior width and a 33″ × 22″ bench is one person sitting upright, not stretching out. If you're fitting it into an alcove or a closet, measure against the 40″ × 44″ exterior and add the 2″ of clearance Clearlight asks for on each side — not the interior figure. For more room, the IS-2 is 45″ inside with a 43″ bench, and the IS-3 is 56″ with a 54″ bench.
Premier IS-2 — $5,799–$6,199 (reg. $6,299–$7,099)
Best for: Most buyers. The best balance of space, value, and Clearlight's core technology.
The IS-2 is the model we'd buy. At $5,799 in basswood or $6,199 in mahogany — $6,299 and $7,099 once the current sale ends on 7 September — for a 2-person far-infrared cabin with lifetime warranty and the lowest-EMF heater system in the category, it's the value anchor of the entire Clearlight lineup. One quirk worth knowing if you want the mahogany: the IS-2 in mahogany is the only cabin in the range carrying a $900 cut rather than the $500 or $700 applied everywhere else, so the wood upgrade costs $400 during the sale and $800 after it. Like the IS-1, the standard IS-2 runs on a 120V/15A circuit — no electrician needed for most homes. That makes it one of the most practical premium saunas to install.
Two people fit in the IS-2, and on your own the whole 43″ bench is yours — enough to sit sideways with your legs up. Lying out flat is a different matter: the longest bench in the Premier range is the IS-3's, at 54″, so no Premier cabin lets an adult stretch out full length. The furniture-grade tongue-and-groove construction, in Eco-Certified Mahogany or Basswood, looks the part from day one. The door seal is tight, and owners consistently describe the joinery on Clearlight cabins as visibly better than budget brands.
Heat-up time: 20–30 minutes to 125–140°F depending on ambient room temperature.
Premier IS-3 — $6,199–$7,099 (reg. $6,699–$7,599)
Best for: Three-person households — and it's the largest Premier cabin Clearlight builds.
The Premier line stops at three people. Clearlight's shop grid and its product sitemap both list exactly three Premier cabins as of 25 August 2026 — the IS-1, IS-2, and IS-3 — so if you've seen a "Premier IS-4" or "IS-5" quoted anywhere, it isn't a model Clearlight currently sells.
The IS-3 is a real footprint upgrade, but check it against the Sanctuary line before you assume it saves you the full-spectrum step. In basswood it does: $6,199 for the IS-3 against $6,899 for a Sanctuary 1 is a $700 gap, and $1,100 separates it from a Sanctuary 2. In mahogany that gap mostly disappears — the IS-3 is $7,099 against $7,299 for a full-spectrum Sanctuary 1, a $200 difference, and it sits only $600 below a Sanctuary 2. A mahogany buyer choosing the IS-3 is paying close to Sanctuary money for a far-infrared cabin, which is a harder case to make than the basswood one. Clearlight lists the interior at 56″ wide × 40″ deep × 71″ high with a 54″ × 22″ bench, and 440 lbs assembled — enough that three people fit without touching knees. It carries the same True Wave II heaters, ELF shielding, and lifetime warranty as the IS-1 and IS-2. Across the Premier range the variables are footprint and electrical draw, not technology.
If you need four or five people in the cabin at once, the Premier line can't do it and you're shopping the Sanctuary series instead. Clearlight sells three larger indoor cabins: the corner-format Sanctuary C, which its product page rates at up to four adults; the Sanctuary Retreat, which Clearlight describes as fitting four to five; and the Sanctuary 5, named for five but described on its own page as built to fit up to four adults. That's a full-spectrum upgrade and a genuine price step, not just a bigger box — read the Sanctuary section below before you assume the capacity is the only thing changing.
Sanctuary Series — Sanctuary 1, 2, 3, C, Retreat and 5
Best for: Buyers who want full-spectrum infrared (near/mid/far) and have a larger budget.
What changes on a Sanctuary is the heaters, not a light panel bolted onto a far-infrared cabin. The front wall carries True Wave® full spectrum heaters — two 500W units on the Sanctuary 1 and 2, four on the Sanctuary 5 — while True Wave far-infrared heaters cover the back wall, side walls, behind your calves and under the floor. Clearlight describes the full-spectrum emitters as delivering over 1,000 watts of near, mid and far infrared simultaneously. That is the whole upgrade: the emitter type in front of you changes, and the rest of the cabin stays far-infrared.
One point of confusion worth heading off. Sanctuary cabins do contain a large LED array — Clearlight's upgraded chromotherapy, which its chromotherapy page specs at 96 medical-grade LEDs across twelve colors, and every Sanctuary product page offers the twelve-color selector to match. A Premier gets a smaller standard system: all three Premier product pages say "15 LED lights in an array of 6 colors" (checked 25 August 2026). Clearlight's older sauna-overview page still quotes 36 LEDs for the Premier, but the per-model product pages are the surface it keeps current — all three were updated on 21 August 2026 against the overview page's May — so we've gone with 15. Either count is visible colored light for mood and color therapy. It is not where the near-infrared comes from, and it is not the reason the Sanctuary costs more than a Premier. Clearlight also sells Red Light Therapy Towers as a separate accessory, which is a genuine LED product but not part of the cabin.
Whether the near-infrared addition meaningfully improves outcomes beyond far-infrared alone is debated. The peer-reviewed literature on photobiomodulation (near-IR's mechanism) is solid, but most sauna-specific research uses far-infrared protocols. The Sanctuary makes sense if you want the full-spectrum option for skin health or recovery protocols — research suggests near-infrared has meaningful effects on collagen production and wound healing — but don't buy it solely expecting superior cardiovascular benefits.
The Sanctuary Retreat is Clearlight's accessibility cabin, and that is the reason it exists. Its product page leads with "wheelchair accessible features including; a removable ramp, wide door, extended handle and lower keyboard", and it is built around a 60″ turn-around radius inside the cabin. If you or someone in the house uses a wheelchair, this is the only Clearlight model designed for it. It is also the one worth calling out if your protocol isn't bench-based: the same page describes two removable benches and says it "could also be used for training and exercise" — take the benches out and you have clear floor space for stretching, yoga, or mat work rather than a fixed bench seat. It's a 240V cabin drawing 3,610 watts / 15.1 amps at 780 lbs, with two flat 34¼″ × 22″ benches when they're in.
The four- and five-person indoor Sanctuary cabins split three ways. The Sanctuary C is the corner-format 4-person cabin — 68″ × 68″ interior, 640 lbs, 240V / 3,330 watts / 13.9 amps — which suits a room where a square cabin against two walls wastes less space than a rectangle. The Sanctuary 5 is the widest indoor cabin at 76¼″ × 44″ interior and 727 lbs, 240V / 3,960 watts / 16.5 amps, with four full-spectrum front-wall heaters rather than two. Worth knowing before you shop it on capacity alone: Clearlight's own copy is inconsistent here — the product name and page title say five people, while the description on the same page says "built to fit up to 4 adults." Treat it as a roomy four rather than a comfortable five.
On post-purchase reliability, the complaint that survives checking is about service speed rather than any specific component: warranty claim processing has drawn repeated criticism for slow turnaround. We went looking for owner reports of a systemic Sanctuary hardware failure mode and could not find one outside rival sauna brands' own blogs, which are not a source we will name a part and a timeline on. If you have first-hand experience of a Sanctuary component failing, we want to hear it.
Outdoor Models — Sanctuary Outdoor 2 and Outdoor 5
Best for: Buyers planning outdoor installation — patio, garden, dedicated outdoor wellness area.
Clearlight's outdoor line is two cabins, not a broad range: the Sanctuary Outdoor 2 and the Sanctuary Outdoor 5. There is no 4-person outdoor model. Both use a weather-resistant DriftwoodTec™ exterior finish rated for outdoor installation with a mahogany interior — not the cedar you'll see quoted elsewhere. These are infrared cabins rather than traditional wood-burning saunas, so no chimney or fire management is required.
Note that both outdoor cabins are Sanctuary models, not Premier ones: they run full-spectrum, with True Wave® full-spectrum heaters on the front wall and far-infrared heaters on the back wall, side walls, behind the calves and under the floor. That is the Sanctuary heater layout, not the far-infrared-only Premier one, and it means the outdoor cabins carry the full-spectrum price step. Both are 240V and need a dedicated circuit — the Outdoor 2 draws 2,320 watts / 9.7 amps (NEMA 6-15p) and the Outdoor 5 draws 3,600 watts / 15 amps (NEMA 6-20p).
Outdoor installation introduces additional considerations: reinforced flooring or a concrete pad is typically needed for the weight (Clearlight lists the Outdoor 2 at 765 lbs, and the Outdoor 5 is larger again), weatherproofing for the electrical connections, and a covered area or additional weather protection is recommended even for weather-rated cabins in high-precipitation climates.
Lead times for outdoor models are comparable to the indoor range — plan for 6–14 weeks minimum.
Clearlight vs. Sunlighten: The Honest Verdict
Since every Clearlight buyer eventually asks this question, here it is plainly:
Choose Clearlight if:
- EMF is your primary concern — <0.3 mG vs. Sunlighten's 3–12 mG on the mPulse
- The lifetime warranty on both heaters and cabinet matters to you
- You want far-infrared at a lower price than Sunlighten's equivalent cabin
- ELF shielding is important to you (Clearlight is among the very few brands to actively address it)
Choose Sunlighten if:
- You want PulseIQ — independently controlled near/mid/far infrared with six programmable wellness protocols
- Clinical research backing on the heater technology specifically matters
- You want integrated red and near-infrared light in a single system with sophisticated app control
For most buyers who aren't specifically chasing the Sunlighten PulseIQ experience, Clearlight is the stronger long-term value — the lifetime warranty on a cabin you'll use for 15+ years is worth more than it sounds on paper.
What to Know Before Buying
The prices are published, just not where you'd look for them. Every Clearlight product page shows a "Get Pricing" form instead of a number, which is a deliberate sales strategy — a pricing conversation is where financing, accessories and installation get sold. The full retail list is real, though: every cabin, both woods, sale and regular price, on a separate page at infraredsauna.com/pricelist. Read that before you fill in the form, so you go into the call already knowing the number. Then get the full delivered price including freight, electrical work and any accessories before you compare.
Lead times are genuinely long. Six to fourteen weeks is the norm, not the exception. If you need a sauna within a month, Clearlight is the wrong brand — look at brands with faster fulfillment.
Assembly is a real project. Most owners manage with a helper over 4–8 hours following Clearlight's instructions, but some buyers report the documentation being ambiguous about electrical integration. DIY assembly on a Sanctuary model can extend significantly. Budget $300–$800 for professional installation if you'd rather not deal with it.
Post-purchase support varies. Pre-sale responsiveness is excellent — Clearlight's sales team is attentive. Post-purchase technical support has drawn criticism for slow response times on warranty claims and technical issues. If something goes wrong 3 years in, be prepared for a longer resolution process than the warranty language implies.
Electrical requirements. Every Premier cabin runs on 120 volts — there is no 240V Premier. Clearlight lists the IS-1 at 1,370 watts and the IS-2 at 1,750 watts / 14.5 amps, both on a standard household outlet with no electrician needed. The IS-3 draws 1,950 watts / 16 amps and wants a 120V/20-amp outlet, which is the one Premier model likely to need an electrician if your room only has a 15-amp circuit. On the Sanctuary side the 120V line is drawn lower than most buyers expect. Only the Sanctuary 1 and Sanctuary 2 run on household power — the Sanctuary 1 at 1,750 watts / 14.6 amps into a 120V/15-amp outlet, the Sanctuary 2 at 2,260 watts / 18.83 amps into a 120V/20-amp outlet on a NEMA 5-20p. Every indoor Sanctuary from the 3-person up is 240V and needs a dedicated circuit, starting with the Sanctuary 3 at 2,800 watts / 12 amps on a NEMA 6-15p — a $7,699–$8,599 cabin, not a top-of-range one. Both outdoor cabins are 240V too, including the 2-person Outdoor 2 at 2,320 watts / 9.7 amps. Add $200–$600 for the electrician on any of those. Always confirm the electrical spec for your specific model and configuration with Clearlight before ordering.
FAQ
Is Clearlight sauna worth the price?
For buyers who prioritize lifetime warranty and the lowest-EMF infrared sauna in the premium segment, Clearlight justifies the premium. If you want comparable far-infrared heat at lower cost, Dynamic Saunas and Maxxus offer 80–90% of the Clearlight experience at 40–60% of the price. Clearlight earns its premium through warranty depth and EMF credentials — not unique technology, since the heater design is now widely replicated.
What is the cheapest Clearlight sauna?
The Premier IS-1 (1-person) is the most accessible entry point at $5,399 in basswood, or $5,899 at regular price. A 2-person Premier IS-2 is $5,799 in basswood and $6,199 in mahogany. Clearlight does publish these figures — they sit on its price list at infraredsauna.com/pricelist rather than on the product pages, which show a "Get Pricing" form instead. Read 25 August 2026; the sale prices run to 7 September 2026.
How long does a Clearlight sauna take to heat up?
Clearlight saunas reach 125–145°F in 20–30 minutes in a room-temperature space. This is faster than Sunlighten's mPulse line, where real-world heat-up times of 45–90 minutes are commonly reported. In a cold unheated garage, budget 35–45 minutes for Clearlight.
What is the difference between Clearlight Premier and Sanctuary?
The Premier delivers far-infrared only via True Wave II heaters — effective for cardiovascular benefits, relaxation, detox, and recovery. The Sanctuary swaps the front wall for True Wave® full spectrum heaters that emit near, mid and far infrared, keeping far-infrared heaters on the back wall, side walls, calves and floor. The near-infrared comes from those heaters, not from an LED panel — the 96-LED array in a Sanctuary is chromotherapy, visible colored light. The step is a flat $1,500 at most matched sizes in the same wood — a Premier 1 in basswood is $5,399 against $6,899 for a Sanctuary 1 in basswood. Two pairs break the pattern. The 3-person mahogany pair is $1,000 at both the sale and the regular price. And the 2-person mahogany pair is $1,500 during the sale but only $1,100 after it, because the Premier 2 in mahogany carries a $900 discount where every other cabin carries $500 or $700 — so the Sanctuary looks like a bigger jump now than it will in September. Whether near-infrared adds meaningful sauna benefits beyond far-infrared is still being established in the research literature.
How does Clearlight compare to Sunlighten?
Clearlight wins on EMF (<0.3 mG vs. Sunlighten's 3–12 mG), ELF shielding, lifetime warranty on heaters and cabinet, and price (typically 20–40% less for comparable capacity). Sunlighten wins on programming sophistication (PulseIQ), clinical research backing, and integrated red light delivery. Most buyers focused on safety specs and long-term value choose Clearlight; buyers who want advanced wellness programming choose Sunlighten mPulse.
What are the most common Clearlight sauna problems?
The most reported issues: 6–14 week delivery delays (sometimes longer), slow post-purchase technical support, DIY assembly complexity that runs longer than documented, and warranty claim processing that can take weeks. The lifetime warranty is broad on paper — heaters, controls, electrical, wood, audio and chromotherapy, with parts and shipping covered for life but labor only for the initial period — so getting a claim honored quickly, and paying for the labor if it lands years later, is where the friction occurs.
Does Clearlight have an ELF shield?
Yes. Clearlight is among the very few sauna brands to actively shield ELF (electric low frequency) fields in addition to EMF. ELF is generated by electrical wiring and components and is distinct from the EMF that most brands address. For buyers purchasing a sauna specifically for health reasons, ELF shielding is the most meaningful differentiator most don't know to ask about.
Our Verdict
Clearlight's Premier IS-2, at $5,799 in basswood and $6,199 in mahogany, is the sauna we'd recommend to most buyers at this end of the range. True Wave II heaters, lifetime warranty, <0.3 mG EMF, ELF shielding, Eco-Certified mahogany or basswood construction — it's the most complete package at that price point from any established brand.
The Sanctuary line is worth the upgrade only if you have a specific reason to want near-infrared alongside far-infrared — a skin health protocol, a recovery setup that specifically targets photobiomodulation, or a Sanctuary Retreat whose removable benches make floor work practical. For general sauna benefits, the Premier delivers everything the research supports at a lower price.
What Clearlight needs to fix: the post-purchase support experience and the lead time reality don't match the premium price. Paying $5,400–$10,400 for a sauna should come with faster, more reliable support after the sale. That's the brand's weakest point, and it's worth knowing before you commit.
If EMF is your primary concern and the lifetime warranty matters to you, Clearlight is still the right choice. If you can live with higher EMF and want more sophisticated wellness programming, Sunlighten's mPulse is the alternative. Either way, both brands are building genuinely good saunas — the decision comes down to what you're optimizing for.
