Clearlight sauna review

Clearlight publishes an unusually complete specification table — interior dimensions, wattage, amperage and plug type for all eleven cabins — and no prices at all. The warranty is the best in this category on paper. The EMF claim is the weakest part of the case.

By Sawyer V.Last updated
Clearlight The Curve Sauna Dome with Amethyst Infrared PEMF Mat

The short version: Clearlight is made by Sauna Works and licenses the Jacuzzi brand for its saunas, a partnership announced in 2017. The line splits into Premier, far infrared only, and Sanctuary, which adds 500 W full-spectrum heaters on the front wall. Eleven residential models run from a 1-person Premier at 1,370 W on a standard outlet to a 5-person Sanctuary at 3,860 W on 240 V. The specification sheets are complete — interior size, bench size, exterior size, weight, wattage, amperage and NEMA plug on every model — and there is no price anywhere on the site. The warranty is a genuine limited lifetime on cabin, heaters, controls and audio, with seven years of labor. The EMF claim is not supported by any published test document.

From Clearlight product pages and the electrical requirements page, read on 2026-09-23. Clearlight notes that added options can push a model up a circuit size — a Sanctuary 2 with upgrades is listed at 120 V/30 A.

Two things in that table are worth pausing on. First, the Premier 3 seats three on a 120 V circuit, which almost nobody else manages — the trade is 2,050 W spread over a 55-inch interior, where a 240 V cabin of the same size would carry more. Second, the amperages are close to their circuit limits: a Sanctuary 2 at 18.83 A on a 20 A circuit leaves very little headroom, and Clearlight's manual tells you to plug directly into a wall outlet rather than a strip or an extension cord. Our outdoor sauna electrical guide covers what a dedicated circuit involves, and infrared sauna buying guide covers how to read a wattage figure against a room size.

Sanctuary versus Premier: what the extra heaters do

Premier cabins are True Wave far infrared on the back wall, front wall, side walls, behind the calves and under the floor. Sanctuary cabins add True Wave full-spectrum heaters on the front wall — two 500 W units on the 1-, 2- and 3-person models, four on the Sanctuary 5 and Outdoor 5. That is the whole difference in kind. Full spectrum adds near and mid wavelengths, which is the part that feels like direct radiant heat on skin rather than ambient warmth; our full spectrum vs far infrared page covers what changes and what does not. Every model we read includes an under-floor heater, which is less common than you would think in this price bracket.

Temperature: 175 °F on the controller, 115 to 125 °F in the room

Clearlight's owner's manual says you can program a maximum of 175 °F, and its own FAQ says the cabins work at comfortable temperatures of 115 to 125 °F, warming for 10 to 15 minutes, with roughly 80 percent of the energy going into your body and 20 percent into the air. Those two numbers are not in conflict — one is a set point, the other is what an infrared cabin actually holds with a body in it — but they do explain why an infrared sauna feels nothing like a traditional room at 190 °F. If the number on the display is what you care about, read infrared vs traditional sauna before you buy either.

The EMF claim, and what is missing behind it

Every Clearlight product page carries the same sentence: that using ultra-sensitive testing equipment, its proprietary heaters cancel out both EMF and ELF, making them the safest on the market. Its blog puts numbers to that — under 1 mG at the heater surface, near 0 mG at the bench, against competitor carbon heaters at 70 to 100 mG — and its FAQ repeats the under-1 mG figure. What we could not find anywhere on the site is a named testing laboratory, a report, a test standard or a date. The company invites customers to check with their own gaussmeters, which is a fair invitation and not a substitute for a published measurement.

That matters because a competitor in the same price bracket does publish one. Sunlighten's Vitatech report names the lab, the engineer, the instruments, the date and the per-model maximum readings. We are not saying Clearlight's heaters are worse; we are saying one brand's claim is checkable and the other's is not. Our what is low EMF page explains what the numbers mean, low EMF sauna comparison compares what brands actually publish, and the Sunlighten review covers the report itself.

From the Clearlight Sanctuary owner's manual warranty table, read on 2026-09-23. The warranty is not transferable, does not apply to display models or to a sauna installed more than six months after delivery, and the labor term is US and Canada only.

Read the two conditions at the bottom of that table again, because they are the ones that catch people: the warranty is void on a cabin installed more than six months after it was delivered, and it does not transfer if you sell the house with the sauna in it. Indoor coverage extends to outdoor use only if you bought the specified water-resistant cover at the same time and keep it on. Compare the whole thing with the rest of the market on our sauna and cold plunge warranties compared page.

Buying, delivery and returns

Clearlight publishes no prices — the site is inquiry-based, which is the single biggest practical difference between shopping this brand and shopping Amazon. Liftgate service and delivery notification are standard, and someone over 18 has to sign. Assembly is quoted at one to three hours with two people and a screwdriver. Returns run 30 business days from receipt with a 25 percent restocking charge, return freight at your cost, and, on anything that shipped under a free or discounted shipping promotion, the original freight cost deducted from the refund. Custom orders are not refundable.

What is not published

  • Prices, anywhere on the site.
  • Any EMF or ELF test report, lab name or standard behind the cancellation claim.
  • A maximum temperature on the product pages — the 175 °F figure is in the owner's manual.
  • Heater surface temperatures or per-heater wattages, beyond the 500 W full-spectrum units.
  • Wood grade detail beyond Eco-Certified Mahogany or Basswood.

Who this is for

Clearlight suits a buyer who wants a cabin with a genuine lifetime parts warranty and seven years of labor, who is comfortable asking for a quote, and who values an under-floor heater and a complete specification sheet. It is a poor fit if you want to compare prices before you talk to anyone, if you need the EMF claim to be backed by a document you can read, or if you might move house and want the warranty to follow the sauna. The Amazon picks below are the same formats from brands that publish their own numbers — the Curve dome is Clearlight's own portable unit.

#ad Price as of Sep 27, 2026. We earn a commission if you buy, at no extra cost to you. How this is funded.

The only Clearlight sauna sold on Amazon, and the only way into its True Wave heaters without a quote and a delivery appointment. It is a lie-down dome, not a room.

Published specifications
Power1,000 W, 120 V, 8.3 A
Temperature range110–153 °F
Dome sizeAdjustable up to 73" L × 35" W × 20" H
Dome weight53 lb
Mat73" × 29.5" × 2", 40 lb, over 25 lb of amethyst
PEMF4 levels: 3, 7.8, 10 and 23 Hz
Warranty7 years residential, per Clearlight

What works

  • Clearlight's own heaters on a standard outlet
  • A published temperature range and wattage
  • Splits into two domes for storage

What doesn't

  • You lie down in it — no sitting up, no sharing
  • The EMF claim has no published test behind it
  • Costs more than most full one-person cabins

Skip it ifyou want to sit upright or share a session. A dome is a solo, horizontal format and nothing changes that.

#2 · Solid red cedar indoors

SalusHEAT 2-Person Low-EMF Far Infrared Sauna, Red Cedar

SalusHEAT

$1,878.99 · View on Amazon

#ad Price as of Sep 27, 2026. We earn a commission if you buy, at no extra cost to you. How this is funded.

Solid red cedar and heaters on the door and lower walls for calves and feet — the parts of you most infrared cabins leave cold.

Published specifications
EMF, as published0–5 mG; no measurement distance given
Power1,750 W
HeatingPanels on the front door, side walls and lower calf and foot zones
Wood100% solid red cedar
Dimensions47.24" × 39.37" × 75.67"
Weight283 lb

What works

  • Genuine solid red cedar, stated as such
  • Heating that reaches calves and feet
  • A two-person cabin at 1,750 W

What doesn't

  • A 0–5 mG range is wide and has no distance
  • 1,750 W is close to a 15 A circuit's rating — give it its own circuit
  • Cedar's aroma is strong for some people

Skip it ifyou are sensitive to aromatic woods. Solid red cedar is the point of this cabin.

#3 · A published EMF range, indoors

CedarLuma 1-Person Infrared Sauna with 660/850 nm Red Light

CedarLuma

$1,279.99 · View on Amazon

#ad Price as of Sep 27, 2026. We earn a commission if you buy, at no extra cost to you. How this is funded.

Publishes an EMF range rather than the word "low", and a realistic warm-up time — up to 149 °F in 45 to 50 minutes — which almost no one does.

Published specifications
EMF, as published1.4–2.6 mG; no measurement distance given
Power1,170 W
Heaters7 carbon fiber panels
Warm-upUp to 149 °F in 45–50 minutes, per the listing
WoodSolid Canadian hemlock
Dimensions31.5" × 31.5" × 63.3"
Weight188 lb

What works

  • A numeric EMF range, not just a claim
  • An honest warm-up time
  • Standard-outlet power for a one-person cabin

What doesn't

  • No distance for the EMF figure, so it cannot be compared precisely
  • "FDA-certified" red light is the seller's description; we have not verified it
  • One person only

Skip it ifyou need to compare EMF figures like for like. Without a distance, no Amazon listing here can be.

#4 · Full-spectrum output

Duthss 3-Person Full-Spectrum Infrared Sauna

Duthss

$3,499.99 · View on Amazon

#ad Price as of Sep 27, 2026. We earn a commission if you buy, at no extra cost to you. How this is funded.

Full spectrum at this size means a 220 V circuit, and the listing says so instead of burying it. That single line is worth more than the whole feature list.

Published specifications
Capacity3 person
Power draw3,600 W
Voltage220 V
Interior60" W × 41" D × 75" H
Heaters4 carbon panels plus 4 red-light tubes
WoodHemlock
ExtrasFoot heating, insulated glass

What works

  • Publishes interior dimensions, not just the outside box
  • Foot heating addresses the most common complaint about infrared cabins
  • The 220 V requirement is stated openly rather than discovered on delivery day

What doesn't

  • 220 V means an electrician, a permit in most jurisdictions and a real install cost
  • No EMF figure published
  • 3,600 W is expensive to run — check the arithmetic before you commit

Skip it ifyou are not prepared to add a 220 V circuit. Budget the electrical work before the cabin, because on this unit the wiring is not optional.

#5 · A published interior

LTCCDSS 2-Person Outdoor Far Infrared Sauna, Canadian Fir

LTCCDSS

$1,880.00 · View on Amazon

#ad Price as of Sep 27, 2026. We earn a commission if you buy, at no extra cost to you. How this is funded.

Publishes interior dimensions as well as exterior, and a sloped roof — the two details that matter most for an outdoor cabin's fit and life.

Published specifications
WoodCanadian soft fir
RoofSloped hillside roof
External57.7" × 40.5" × 81.1"
Interior39.4" × 33.5" × 71.7"
Weight280 lb

What works

  • Interior dimensions published
  • A roof that sheds water
  • Relatively light

What doesn't

  • The listing's capacity claims are inconsistent — the interior suits one or two
  • Fir is less rot-resistant than cedar
  • Power not in the feature text

Skip it ifyou want room to spread out. The published interior is snug for two.

The Curve is Clearlight's own product and the only one of its saunas you can buy on Amazon. The rest are not Clearlight units and we are not claiming equivalence — they are the cedar and full-spectrum cabins Amazon sells in the sizes Clearlight's line covers, each with its own published specifications.

Questions people actually ask

Is Clearlight the same as Jacuzzi?
Clearlight Infrared and Jacuzzi announced an exclusive licensing partnership in April 2017, under which Clearlight manufactures and markets a premium infrared sauna line under the Jacuzzi brand. The manufacturing entity named on the warranty is Sauna Works, Inc.
How hot does a Clearlight sauna get?
The owner's manual says you can program a maximum of 175 °F. Clearlight's own FAQ says the cabins work at 115 to 125 °F in practice, because an infrared sauna heats your body more than the air. Both figures are the brand's.
Are Clearlight saunas low EMF?
Clearlight says its True Wave heaters cancel out EMF and ELF and quotes figures under 1 mG at the heater surface. We could not find a named laboratory, a test report or a standard published anywhere on the site to support that, so treat it as a manufacturer claim rather than a measurement you can check.
What does the Clearlight warranty actually cover?
For indoor residential use: lifetime on the cabin, factory-installed heaters, controls and audio, with seven years of labor in the US and Canada. It is not transferable, it excludes display models, and it does not apply to a sauna installed more than six months after delivery. Outdoor use drops the cabin term to five years.
Can you buy a Clearlight sauna on Amazon?
The cabins are sold direct. The Curve portable sauna dome and some accessories are listed on Amazon; the Sanctuary and Premier cabins are not.
