Jacuzzi Infrared Sauna Review (2026): The Clearlight Connection Explained

One thing before anything else: this review is published by Peak Saunas, a direct competitor of both Jacuzzi's sauna line and Clearlight. That's exactly why every claim below is either quoted from one of their own live pages, attributed to a named third party, or clearly flagged as our opinion — and why their real strengths get conceded first, at full volume. Every source is linked at the bottom. Check us.

The Clearlight connection, explained plainly

This is the question almost nobody answers straight, so here it is with the receipts.

What the 2017 announcement actually says

On April 25, 2017, Clearlight Infrared published an announcement titled Clearlight Infrared and Jacuzzi Inc. Form a Licensing Partnership for Jacuzzi® Infrared Saunas (accessed August 2026). In it, Clearlight states that it will manufacture and market a line of infrared saunas under the Jacuzzi® brand name, and names the two lines involved: the Clearlight Sanctuary™ Full Spectrum Infrared Sauna models and the Clearlight Premier™ Far Infrared Sauna models. Clearlight founder Dr. Raleigh Duncan and then-Jacuzzi Group Worldwide CEO Bob Rowan are both quoted. The trade press reported the same arrangement independently: Kitchen & Bath Business, June 20, 2017, wrote that Clearlight Infrared would manufacture and market a line of infrared saunas under the Jacuzzi brand.

So the short version, in the companies' own words: Jacuzzi licensed its name; Clearlight builds the saunas. That is a brand license, not a merger, and it is stated by Clearlight rather than inferred by us.

What their pages look like today — and why that matters

Here's the part that trips people up. As of August 5, 2026, the two sites behave as if the other doesn't exist:

• jacuzzi.com brands the line as Jacuzzi® Saunas, names the models JS-1i, JS-2i and JS-3i, and closes every page with © 2026 Jacuzzi Inc. All rights reserved. We read the US saunas landing page, the infrared light therapy page, and all three model pages. None of them names Clearlight anywhere.
• infraredsauna.com brands itself Clearlight® Saunas, sells the Sanctuary™, Sanctuary™ Outdoor, Premier™ 1/2/3, The Curve™ dome and custom cabins, and closes with © 2026 Clearlight® Saunas. Its model index and warranty page make no mention of Jacuzzi.

None of that contradicts the 2017 announcement — brand licenses routinely run this way. But it does mean you cannot assume a JS-2i is a rebadged, spec-for-spec Clearlight Premier 2, because neither company currently publishes a model-to-model map. The practical advice that falls out of this is the most useful sentence on the page: whichever badge you buy, get the model number, the light specs and the warranty term in writing from your salesperson before you pay. The two badges genuinely differ on that last one, as the next section shows.

What this line genuinely gets right

A real doctor-founder origin

Clearlight was founded by Dr. Raleigh Duncan, a Board-Certified Doctor of Chiropractic, and has been building infrared saunas for roughly 28 years (their founder page, accessed August 2026). "Doctor designed" is not marketing invention here — it is the company's actual origin story, and it's older than most brands in this category by two decades. The ergonomic backrest that Jacuzzi's JS pages describe as chiropractor-designed traces back to exactly that lineage.

The strongest headline warranty in the category — on the Clearlight badge

Clearlight's warranty page (accessed August 2026) states a limited lifetime residential warranty covering, in its words, the entire sauna — heaters, controls, electrical and wood, even the included audio system — with a 5-year term for commercial installations. That is a genuinely excellent headline term, better than ours on paper, and we'll say so plainly. As with any lifetime warranty from anyone, read the current exclusions document before you buy.

Brand-name reassurance and a showroom you can actually visit

Jacuzzi is one of the few household names in the entire wellness-equipment category, and its sauna line rides a hot-tub dealer network that has been selling heavy freight equipment locally for decades. The JS model pages offer See in Showroom alongside Get a Quote, and delivery runs through your local authorized Jacuzzi® professional. For a buyer who wants to sit in a cabin before spending five figures and wants a local phone number afterward, that is a real advantage — and it is one we can't match, since Peak sells direct only.

The red light tower is the best add-on for a sauna you already own

Credit where it belongs: if you already own an infrared cabin and want to add full-body light therapy, Clearlight's separately sold Red Light Therapy tower is the strongest add-on option in the category. It's a legitimate product with real mounting hardware, and buying it beats replacing a sauna you're otherwise happy with. Our objection, below, is only to what it costs when you're buying a new cabin.

The flags: what to check before you buy

None of this is a scandal. All of it is checkable on their own pages, and all of it belongs in a five-figure decision.

1. Same lineage, two very different warranties

This is the most practical finding on the page. Every Jacuzzi JS model page — JS-1i, JS-2i, JS-3i — states, quoted as written on August 5, 2026: 5 Year comprehensive warranty covers the entire sauna for manufactures defects. Clearlight's own cabins carry a limited lifetime residential term. Five years is a perfectly respectable warranty; it is not a lifetime warranty. If the lifetime term is why you're drawn to this family of saunas, the Jacuzzi badge is not the one that carries it — a distinction we have never seen stated plainly in a review, and one worth a phone call before you order.

2. No published prices on either badge

Neither company publishes per-model cabin pricing. On jacuzzi.com, every JS page routes to a See Price Now form, a Get a Quote link, or a local dealer; if no certified dealer covers your ZIP code, the site tells you so. The single published number we could find anywhere in the line is a financing callout on the US saunas page reading, verbatim: Own a sauna for $130/month¹ for 72 months², interest-free ($9,354 MSRP) — with a footnote noting financing is available at participating dealers only (accessed August 5, 2026). Treat that $9,354 as one MSRP data point attached to a finance offer, not as a price list.

Clearlight is at least candid about the policy. Its model index states, in its own words: Instead of disclosing pricing, we offer an experience tailored to your unique needs and aspirations — while ensuring every sale is accounted for, and the most accurate price is quoted to you. That's a defensible business choice and plenty of buyers don't mind it. It does mean you cannot compare this line against anything without first entering a sales process. We've mapped what buyers actually report paying in how much a Clearlight sauna costs.

3. Red light therapy: described on one badge, sold separately on the other, specified on neither

The Jacuzzi JS pages say, verbatim: Jacuzzi Saunas include high intensity red light therapy allowing you to enjoy the benefits of light therapy in every session. That's the entire disclosure. As of August 2026, those pages publish no wavelength list and no irradiance figure (mW/cm²) at any distance — and "high intensity" is not a unit. Wavelength mix and delivered dose are precisely the two variables the photobiomodulation literature turns on, so a page without them leaves you unable to compare therapeutic value against anything.

On the Clearlight badge, full-body red light isn't included at all — it's a separate tower. Their published upgrades price list (verified August 5, 2026) shows Red Light Therapy at $999 (PERSONAL), $1,599 (CORE) and $2,199 (FULL BODY), plus $295 for the floor stand or $105–$180 for the various mounts. So on a new cabin purchase, full-body light therapy is a roughly $2,500 line item on top of a quote you haven't seen yet.

For contrast — and yes, this is the competitor talking, so verify it — every Peak full-spectrum model includes a full-body panel as standard: 8 wavelengths (630–1060nm), 216 dual-chip LEDs, with irradiance published at three distances (175 mW/cm² at 6″, 107 at 12″, 80 at 24″). Our methodology is in the 2026 red light therapy sauna guide.

4. Electrical requirements run high on the 2- and 3-person cabins

Per the JS model pages (August 5, 2026): the JS-1i runs 120V / 2,100W / 17.5A on a NEMA 5-20 plug, but the JS-2i jumps to 240V / 2,340W / 9.75A on a NEMA 6-15, and the JS-3i to 240V / 3,640W / 15.16A on a NEMA 6-20. In other words, the 2-person cabin already needs a 240V outlet most homes don't have in a spare room — usually an electrician visit. Worth pricing before you commit. By comparison, the 2-person Peak Fuji runs on 120V/20A.

5. Delivery-condition and quality-control themes in third-party reviews

The company behind the saunas, Sauna Works (Clearlight Infrared Saunas), holds an A+ BBB rating and has been BBB accredited since July 21, 2006 — two decades of accreditation is a real trust signal and we'll lead with it. Alongside it, recent reviews on that same BBB profile (read August 5, 2026) describe a unit arriving with multiple defects the reviewer felt quality control should have caught, several service calls needed to reach working condition, and app and WiFi connectivity trouble. On Trustpilot, the profile stood at 4.4/5 across roughly 1,483 reviews when we checked it on August 5, 2026 — a good score — with the 1- and 2-star reviews repeating specific themes: damage or scratches found on delivery, long waits for replacement parts, and app connectivity failures. Every company shipping heavy freight accumulates some of this; the pattern worth noting is delivery condition and post-sale parts speed, not the volume. We documented both sides, with citations, in our Clearlight problems review.

Head to head: the cabins a buyer actually cross-shops

If you're quoting a JS-2i or JS-3i, these are the two Peak cabins sitting in the same size and price territory. Every Peak figure below is live on our product pages right now; every Jacuzzi figure is from theirs, on August 5, 2026.

The honest summary of that table: Jacuzzi gives you a name, a showroom and a salesperson; Peak gives you the numbers up front. Full write-ups: Peak Fuji review · Peak Matterhorn review · the full lineup.

Where Peak is actually different

Four differences, stated so you can check each one rather than take our word for it.

• Red light therapy is standard, and published. Every Peak full-spectrum model includes a full-body panel: 8 wavelengths (630–1060nm), 216 dual-chip LEDs, and irradiance published at three distances — 175 mW/cm² at 6″, 107 at 12″, 80 at 24″. Not an upgrade line item, and not a one-sentence adjective.
• Transparent live pricing. Every model shows its price on its own page — $5,950 through $16,750 across the lineup as of August 2026 — with free shipping, 0% APR financing up to 24 months, and HSA/FSA eligibility through Truemed. No form stands between you and the number.
• Warranty in plain terms. Limited lifetime on structure, wood and heating elements (defined as 7 years residential); 7-year red light panel; lifetime U.S.-based support. Clearlight's residential headline is longer than ours and we've said so above — but ours is defined in the open rather than in a document you download after the quote.
• Guided wellness included. Peak Wellness Club included free for life — daily guided sessions and 30-day programs — which no other sauna brand includes. A Jacuzzi or Clearlight cabin heats up and plays music; it doesn't tell you what to do in there on a Tuesday in month seven, which is when most sauna ownership quietly ends.

Who should buy which

Find the sentence that sounds like you.

• "I want a brand my spouse has heard of." → Jacuzzi. It is the most recognized name that will ever be attached to a sauna in your house, and that reassurance is a legitimate thing to buy.
• "I need to sit in it before I spend five figures." → Jacuzzi. The dealer and showroom network is the real advantage here, and no direct-to-consumer brand — including us — can offer you a local room to try one in.
• "The lifetime warranty is why I'm here." → Then buy the Clearlight badge, not the Jacuzzi one. The limited lifetime residential term is on Clearlight's cabins; the Jacuzzi JS pages state 5 years. Same lineage, different paperwork.
• "I already own a sauna and just want full-body red light." → Clearlight's Red Light Therapy tower, $999–$2,199 plus a mount. Adding light to a cabin you like beats replacing it, and this is the best add-on in the category.
• "I want to know the price and the light specs before I talk to anyone." → Peak. Live prices, published wavelengths and irradiance at three distances, free shipping. Start with the Fuji ($8,250) against a JS-2i quote, or the Matterhorn ($10,750) against a JS-3i.
• "I don't have a 240V circuit and don't want an electrician." → Check carefully. The JS-2i needs 240V; the 2-person Peak Fuji runs on 120V/20A.
• "I'm cross-shopping this whole tier." → Read the spec-by-spec Peak vs Clearlight comparison, which concedes their wins by name, and our roundup of the best Clearlight alternatives, where five of nine category wins go to brands other than us.

FAQs

Is a Jacuzzi sauna the same as Clearlight?

Not identical, but they share an origin. Clearlight Infrared announced an exclusive licensing partnership with Jacuzzi Inc. on April 25, 2017, under which Clearlight would — in its own words — manufacture and market a line of infrared saunas under the Jacuzzi brand name, covering the Clearlight Sanctuary full-spectrum and Clearlight Premier far-infrared model lines. As of August 2026, though, the two storefronts run separately: jacuzzi.com sells JS-1i, JS-2i and JS-3i cabins with a 5-year comprehensive warranty through its authorized dealer network, while infraredsauna.com sells Sanctuary and Premier cabins direct with a limited lifetime residential warranty, and neither brand's current product pages mention the other. Treat them as related but not interchangeable, and get the model, the light specs and the warranty term in writing before you buy either.

Who makes Jacuzzi infrared saunas?

Clearlight Infrared, per Clearlight's own 2017 announcement, which states that Clearlight Infrared will manufacture and market a line of infrared saunas under the Jacuzzi brand name. Kitchen and Bath Business reported the same arrangement in June 2017. Jacuzzi's own current sauna pages do not name Clearlight anywhere and carry only a 2026 Jacuzzi Inc. copyright line, as of August 2026 — so if the connection matters to your purchase, ask the dealer to confirm it in writing rather than relying on either website.

How much does a Jacuzzi infrared sauna cost?

Jacuzzi does not publish per-model sauna prices. As of August 2026, every JS-1i, JS-2i and JS-3i page routes to a See Price Now form, a Get a Quote link, or a local authorized dealer. The one published figure anywhere in the line is a financing callout on Jacuzzi's US saunas page citing a $9,354 MSRP at $130 per month for 72 months, interest-free at participating dealers — one MSRP data point attached to a finance offer, not a price list. Clearlight is quote-gated too, and says so directly: instead of disclosing pricing, it offers an experience tailored to your unique needs and aspirations. Because both route through quotes, your actual number depends on model, options and dealer, so get it in writing before comparing against brands that publish prices.

Does a Jacuzzi infrared sauna include red light therapy?

The Jacuzzi-branded JS pages say yes, in a single sentence: Jacuzzi Saunas include high intensity red light therapy allowing you to enjoy the benefits of light therapy in every session. What those pages do not publish, as of August 2026, is a wavelength list or an irradiance figure at any distance — the two numbers the photobiomodulation literature actually turns on. On the Clearlight-branded side, full-body red light is a separate purchase: the published upgrades list shows the Red Light Therapy tower at $999 personal, $1,599 core and $2,199 full body, plus $295 for the floor stand. That tower is genuinely the best add-on if you already own a sauna and want to add light therapy. Every Peak full-spectrum model instead includes a full-body panel standard: 8 wavelengths (630–1060nm), 216 dual-chip LEDs, irradiance published at three distances.

What warranty comes with a Jacuzzi infrared sauna?

Five years. Each Jacuzzi JS-1i, JS-2i and JS-3i page states a 5 Year comprehensive warranty covers the entire sauna for manufactures defects, quoted as written, as of August 2026. That is materially shorter than the Clearlight-branded headline, which is a limited lifetime residential warranty covering the entire sauna including heaters, controls, electrical and wood, with 5 years for commercial use. Same lineage, different paperwork — which is the single most practical reason to know which badge you are buying.

Where can you buy a Jacuzzi infrared sauna?

Through Jacuzzi's authorized dealer and showroom network. The JS model pages offer See in Showroom and Get a Quote paths, and Jacuzzi's pages note that delivery runs through your local authorized Jacuzzi professional; if no certified dealer covers your delivery ZIP code, the site tells you so. Clearlight, by contrast, sells direct from infraredsauna.com through its Sauna Specialists, and Peak sells only at peaksaunas.com with a live price on every model page and free shipping.

Jacuzzi vs Peak Saunas: which should I buy?

Buy Jacuzzi if a household brand name, a local showroom you can sit in, and a dealer relationship are what make you comfortable spending five figures. Buy Peak if you want the numbers before the phone call: live prices on every model page — the 2-person Fuji at $8,250 and the 3-person Matterhorn at $10,750 as of August 2026 — with a full-body red light panel included standard at 8 wavelengths (630–1060nm) and 216 dual-chip LEDs, irradiance published at three distances (175 mW/cm² at 6 inches, 107 at 12 inches, 80 at 24 inches), free shipping, limited lifetime coverage on structure, wood and heating elements (defined as 7 years residential), a 7-year red light panel warranty, and lifetime U.S.-based support. Peak also includes Peak Wellness Club free for life — daily guided sessions and 30-day programs — which no other sauna brand includes.

Are Jacuzzi infrared saunas worth it?

For the right buyer, yes. You are getting a cabin from a lineage that traces to Clearlight Infrared, a company founded by Dr. Raleigh Duncan, a Board-Certified Doctor of Chiropractic, with an A+ BBB rating and accreditation dating to 2006, plus one of the strongest headline warranties in the category on the Clearlight-branded side. Weigh that against the checkable trade-offs as of August 2026: the Jacuzzi badge carries 5 years rather than lifetime, no per-model price is published on either brand's site, no wavelength or irradiance figures are published for the red light, the 2- and 3-person cabins need 240V, and BBB and Trustpilot reviews repeat delivery-condition and quality-control themes. If those matter more to you than the brand name, compare against cabins that publish their prices and light specs outright.

Disclosure: This review is published by Peak Saunas, a direct competitor of both Jacuzzi's infrared sauna line and Clearlight. We have an obvious interest in the outcome, which is why their genuine strengths — the doctor-founder origin, the limited lifetime residential warranty on the Clearlight badge, the dealer and showroom network, and the red light tower as the best add-on for an existing sauna — are conceded above at full strength, why 4 of the 7 buyer profiles route to Jacuzzi or Clearlight rather than to us, why every critical claim is limited to what one of their own live pages or a named third party shows, and why every figure is date-stamped August 5, 2026. Prices, specs and terms change; verify on their sites before buying.
