Clearlight saunas come in twelve models organized into four lines. The Sanctuary Indoor line (six models: Sanctuary 1, 2, 3, 5, C, and Retreat) delivers full-spectrum infrared — near, mid, and far infrared combined. The Premier Indoor line (three models: 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) brings full-spectrum Sanctuary-grade saunas to permanent outdoor installation. The Curve Dome is the portable far-infrared dome for renters and space-constrained buyers. Every Clearlight indoor and outdoor cabin sauna ships with a Lifetime residential warranty covering the entire sauna. True Wave carbon-ceramic heaters with independently tested EMF below 0.8 milligauss across the entire lineup. Every Sauna Republic invoice includes a "Pay with Truemed" option for HSA/FSA.

The Clearlight sauna lineup at a glance
The full Clearlight sauna catalog covers twelve models. The table below shows every sauna currently available with its primary specs — capacity, spectrum, electrical, and footprint. Each sauna is covered in depth in its dedicated section further down, with an image and direct link to the full product page.
| Model | Capacity | Spectrum | Electrical | Exterior dimensions |
|---|---|---|---|---|
| Sanctuary 1 | 1-person | Full spectrum | 120V / 15A | 42.5" × 48.25" × 77" |
| Sanctuary 2 | 2-person | Full spectrum | 120V / 20A | 51.75" × 47.75" × 77" |
| Sanctuary 3 | 3-person | Full spectrum | 240V / 15A | 71" × 48" × 77" |
| Sanctuary 5 | 5-person | Full spectrum | 240V / 20A | 82.25" × 47.25" × 77" |
| Sanctuary C | 4-person corner | Full spectrum | 240V / 15A | 71.25" back × 38.25" sides × 47.5" front × 77" |
| Sanctuary Retreat | 4-person wheelchair-accessible | Full spectrum | 240V / 20A | 76.5" × 64.5" × 85" |
| Premier IS-1 | 1-person | Far infrared only | 120V / 15A | 40" × 44" × 76" |
| Premier IS-2 | 2-person | Far infrared only | 120V / 15A | 50" × 44" × 76" |
| Premier IS-3 | 3-person | Far infrared only | 120V / 20A | 61" × 44" × 76" |
| Sanctuary Outdoor 2 | 2-person outdoor | Full spectrum | 240V / 15A | 57" × 52" × 80" |
| Sanctuary Outdoor 5 | 4-5 person outdoor | Full spectrum | 240V / 20A | 82.25" × 51.5" × 80" |
| Curve Dome | 1-person portable | Far infrared only | 2× 120V / 15A | 73" × 35" × 20" (dome + mat) |
Three patterns to understand before diving into individual sauna sections. First, full-spectrum vs far-infrared-only is the single biggest decision in the Clearlight lineup — Sanctuary is full spectrum, Premier is far infrared only. Second, capacity scales predictably with electrical requirements — 1-to-2-person saunas typically run on standard 120V household outlets, while 3-person and larger saunas require a dedicated 240V circuit. Third, every indoor and outdoor Clearlight cabin sauna carries a Lifetime residential warranty covering the entire sauna, which is the strongest warranty coverage available in the premium infrared sauna market.
Sanctuary Indoor Full Spectrum lineup (6 models)
The Sanctuary Indoor line is Clearlight's full-spectrum flagship — six models combining True Wave carbon-ceramic far infrared heaters (back wall, side walls, calf heaters, floor heater) with full-spectrum infrared heaters on the front wall that deliver near, mid, and far infrared wavelengths simultaneously. Every Sanctuary is built from eco-certified mahogany or basswood, rated for permanent indoor installation, and backed by Clearlight's Lifetime Residential warranty covering the entire sauna. Smart Device Control is available across the Sanctuary line as an optional add-on for smartphone-based remote operation.
Sanctuary 1 — single-person full spectrum
The entry point to the Sanctuary line. 1-person capacity, 42.5" × 48.25" footprint, standard 120V/15A household outlet (no electrician required). 1,750W total heater output with True Wave full-spectrum heaters on the front wall and True Wave far infrared heaters on the back wall, side walls, calf heaters, and floor. Features include chromotherapy lighting, Bluetooth audio, oxygen ionizer, floor heater, glass roof, and double doors. Weighs 425 lbs assembled. For buyers who want the complete Sanctuary experience in the smallest footprint possible — renters with power limitations, buyers with tight spare-room layouts, or anyone who wants solo sauna sessions without the capacity of a multi-person cabin.
Sanctuary 2 — two-person full spectrum
The most-purchased Sanctuary model for couples and individuals who occasionally share sessions. 2-person capacity, 51.75" × 47.75" footprint, 120V/20A outlet (NEMA 5-20P — not a standard 15A outlet, check your electrical before ordering). 2,000W total with two 500W True Wave full-spectrum heaters on the front wall plus full far-infrared heater coverage. Same feature set as the Sanctuary 1, including a partial glass ceiling. 450 lbs assembled. If you are the only one using the sauna most of the time but want the option to share a session with a partner, this is the model most specialists recommend.
Sanctuary 3 — three-person full spectrum
The first Sanctuary model requiring a dedicated 240V/15A circuit (NEMA 6-15P — licensed electrician recommended). 3-person capacity, 71" × 48" footprint, 2,800W total output. Includes the full glass roof (the Sanctuary 2 has a partial glass ceiling). Bench dimensions expand to 66" × 22" with 20" height to accommodate three adults comfortably. 580 lbs assembled. For small families, couples who want room to stretch out, or buyers planning to host guests for sessions.
Sanctuary 5 — five-person full spectrum
The largest standard-layout Sanctuary cabinet. 5-person capacity (76.75" × 21.25" bench), 82.25" × 47.25" footprint, 240V/20A circuit (NEMA 6-20P), 3,960W total with four 500W True Wave full-spectrum heaters across the front wall plus full far-infrared coverage. Glass roof included. 727 lbs assembled. For larger families, commercial settings running individual or small-group sessions, and buyers who want the most spacious Clearlight indoor footprint without moving to a corner layout.
Sanctuary C — four-person corner
The corner-layout Sanctuary designed to use otherwise-dead space in a room. 4-person capacity with an L-shaped bench (left bench 66.25" × 22", right bench 44.5" × 22"), 71.25" back walls × 38.25" sides × 47.5" front, 77" height. 240V/15A circuit (NEMA 6-15P). 3,330W total output. Recliner-compatible — one of only two Clearlight indoor saunas that fit the Sanctuary Recliner Chair. 640 lbs assembled. For buyers with room corners to spare, open-plan home gyms, or anyone who wants multi-person capacity without committing to a rectangular footprint in the middle of a room.
Sanctuary Retreat — four-person wheelchair-accessible
The only wheelchair-accessible sauna in the Clearlight catalog. 4-person capacity with two removable benches (34.25" × 22" each), 76.5" × 64.5" footprint, 85" tall (taller than the standard 77" Sanctuary line). 36" wheelchair-accessible doorway with included ramp, 60" turnaround clearance, removable benches to accommodate wheelchair users. 240V/20A circuit (NEMA 6-20P), 3,570W. Recliner-compatible. 780 lbs assembled. For buyers with accessibility needs, facilities serving wheelchair-access requirements (spas, wellness clinics, medical practices), or multi-generational households planning for long-term accessibility.
Which Sanctuary model fits your space?
Sauna Republic's specialists walk through your available space, electrical setup, and capacity needs to identify the right Sanctuary model. Pricing requests are answered by a human, not a form bot.
Get PricingPremier Indoor Far Infrared lineup (3 models)
The Premier line delivers Clearlight's True Wave far infrared heater technology at a more accessible price point than the Sanctuary line — without the front-wall full-spectrum heaters. For buyers focused on deep-tissue far infrared therapy at the 6 to 14 micron wavelength (the therapeutic band for most infrared sauna benefits), the Premier line gives you Clearlight-grade heaters, Clearlight-grade EMF performance, and Clearlight-grade warranty coverage. Every Premier includes the ergonomic backrest as a standard feature (unlike the Sanctuary line, where the Moveable Ergonomic Backrest is a separate accessory purchase).
Premier IS-1 — single-person far infrared
1-person capacity, 40" × 44" footprint, standard 120V/15A household outlet (NEMA 5-15P — no electrician required). 1,370W total output with True Wave far infrared carbon-ceramic heaters on the back wall, side walls, calf heaters, and under-floor heater. Bench 33" × 22" × 17.5" with included ergonomic backrest. Features include chromotherapy, Bluetooth audio, oxygen ionizer, and floor heater. 325 lbs assembled. The smallest and lightest Clearlight indoor cabinet in the catalog. For buyers who want clinical-grade far infrared therapy at the most accessible Clearlight price point.
Premier IS-2 — two-person far infrared
2-person capacity, 50" × 44" footprint, 120V/15A standard household outlet (no electrician required). 1,750W total output. Bench 43" × 22" × 17.5" with included ergonomic backrest. Same feature set as IS-1. 395 lbs assembled. Notable because this is the largest Clearlight indoor sauna that still runs on a standard 120V/15A outlet — the Sanctuary 2 (120V/20A), Sanctuary 3 (240V/15A), and larger models all require circuit upgrades or electrician work. For buyers who want 2-person capacity with no electrical modifications to their home.
Premier IS-3 — three-person far infrared
3-person capacity, 61" × 44" footprint, 120V/20A outlet (NEMA 5-20P — one horizontal blade, not a standard 15A outlet). 1,950W total output. Bench 54" × 22" × 17.5" with ergonomic backrest. 440 lbs assembled. The IS-3 is the largest Premier cabinet and notably runs on a 120V/20A circuit rather than the 240V circuits that the equivalent-capacity Sanctuary 3 requires — a meaningful electrical simplification for buyers who want 3-person capacity without installing 240V wiring.
Is Premier the right line for you?
The Sanctuary vs Premier decision is the single biggest question in Clearlight indoor sauna buying. Read our full Sanctuary vs Premier comparison guide for side-by-side specs, heater details, and the complete decision framework.
Get PricingSanctuary Outdoor Full Spectrum lineup (2 models)
The Sanctuary Outdoor line takes the full-spectrum Sanctuary heater stack and packages it in a weather-rated cabinet built for permanent outdoor installation. Gray Cedartec exterior (weather-rated cedar composite), mahogany interior, IPX4 weather rating, side windows on both models plus front windows on the Outdoor 5. Both are full-spectrum Sanctuary-grade saunas. Warranty is a Lifetime Residential warranty covering the entire sauna, with a 5-year cabin warranty reflecting the outdoor exposure. Smart Device Control is available across the Sanctuary Outdoor line as an optional add-on for smartphone-based remote operation.
Sanctuary Outdoor 2 — two-person outdoor full spectrum
2-person capacity, 57" × 52" × 80" exterior footprint, 240V/15A dedicated circuit (NEMA 6-15P — licensed electrician recommended). 2,480W total output with True Wave full-spectrum heaters on the front wall plus full far-infrared coverage throughout the cabin. Bench 50" × 22" × 20". Features include chromotherapy, Bluetooth audio, oxygen ionizer, floor heater, IPX4 weather rating, and side windows. 765 lbs assembled. Requires a flat weight-bearing surface (concrete pad, paver base, or reinforced deck) and the 240V circuit — most buyers schedule an electrician during the pre-delivery window.
Sanctuary Outdoor 5 — four-to-five person outdoor full spectrum
4-to-5 person capacity, 82.25" × 51.5" × 80" exterior footprint, 240V/20A dedicated circuit (NEMA 6-20P). 3,800W total output with four True Wave full-spectrum heaters plus full far-infrared coverage. Bench 77.25" × 22" × 20". Adds front windows on top of the side windows included in the Outdoor 2. 1,050 lbs assembled. The largest Clearlight sauna in the catalog. For larger families, commercial outdoor installations (wellness retreats, outdoor spa facilities, recovery-focused gyms), or buyers who want backyard group sauna sessions at multi-person capacity.
Thinking about an outdoor Clearlight sauna?
The outdoor buying decision has its own considerations — installation surface, weather exposure, 240V electrical, and the Outdoor 2 vs Outdoor 5 capacity question. Read our Clearlight Outdoor Sauna buying guide for the full breakdown.
Get PricingClearlight Curve Dome portable sauna
Shop the Clearlight Curve Dome
The Curve Dome is the portable sauna in the Clearlight catalog — a two-piece clamshell far infrared dome you lie down inside of, with your head staying outside the dome in cool air. For buyers who cannot install a cabin sauna (renters, apartment dwellers, buyers without square footage for a permanent wooden enclosure, or anyone who moves too often to justify permanent construction), the Curve delivers Clearlight-grade True Wave far infrared heaters and below-0.8-milligauss EMF performance in a format that plugs into two standard 120V outlets, weighs 93 pounds total, and sets up in minutes on any flat surface.
The Curve ships bundled with the full-size Clearlight Amethyst Infrared PEMF Mat (73" × 29.5" × 2", 40 lbs, 25+ lbs amethyst crystal, 10 PEMF cores, negative ion therapy) as part of the purchase — not a separate accessory add-on. Total package is the dome (53 lbs) plus the mat (40 lbs) for a combined 93-lb setup. Warranty is 7-year residential and 5-year commercial on both dome and mat.
Format trade-offs to understand: the Curve is single-person only, lie-down only (no upright sauna experience), and far infrared only (no full-spectrum option in the portable format). If you want the upright cabin sauna experience, multi-person capacity, or full-spectrum infrared, a Sanctuary or Premier cabin is the right answer. If a cabin is physically impossible for your situation and you want serious Clearlight-grade infrared therapy anyway, the Curve is the purpose-built answer.

Get PricingSanctuary vs Premier: the core decision
If you are buying a Clearlight indoor cabin sauna, Sanctuary vs Premier is the question that matters most. Capacity choices come second, electrical requirements fall out of capacity, and every other decision flows from there. Understanding the spectrum difference is the foundation.
| Dimension | Sanctuary (Full Spectrum) | Premier (Far Infrared Only) |
|---|---|---|
| Front wall heaters | True Wave full-spectrum heaters (near + mid + far) | Not applicable |
| Back + side wall heaters | True Wave far infrared (6–14 micron) | True Wave far infrared (6–14 micron) |
| Calf + floor heaters | Included | Included |
| Wavelengths delivered | Near infrared (~700–1400 nm) + mid (~1400–3000 nm) + far (6–14 μm) | Far infrared only (6–14 μm) |
| Ergonomic backrest | Separate accessory purchase | Included standard |
| Smart Device Control | Optional add-on | Not available |
| Typical price point | Premium (higher) | More accessible (lower) |
| EMF performance | <0.8 mG | <0.8 mG |
| Warranty | Lifetime residential (entire sauna) | Lifetime residential (entire sauna) |
The practical question boils down to whether you specifically want near-infrared wavelengths in your sauna sessions. Near-infrared (~700–1400 nm) is the wavelength band associated with skin penetration, mitochondrial function, and red-light-therapy-adjacent benefits. The Sanctuary front-wall full-spectrum heaters put that wavelength band into your sauna cabin directly. If near-infrared is specifically important to your wellness goals, Sanctuary is the right line. If deep-tissue far infrared therapy at the Clearlight price floor is the priority, Premier delivers that at a more accessible entry point without compromising heater technology or warranty coverage.

Get PricingWhat makes Clearlight saunas different
Three technical commitments define why Clearlight sits at the top of the premium infrared sauna market, and why the Clearlight price point reflects engineering rather than marketing markup.
Clinical heritage is the quieter fourth commitment. Clearlight was founded by Dr. Raleigh Duncan specifically because he wanted a better sauna for his own chiropractic practice than what existed in the market. That origin shows up in small engineering decisions across the lineup — the doctor-designed Moveable Ergonomic Backrest, the wheelchair-accessible Sanctuary Retreat, the recliner compatibility on the Sanctuary C and Retreat, the clinical-grade EMF testing protocols — and it explains why Clearlight saunas are specified into chiropractic offices, physical therapy clinics, wellness studios, and medical practices worldwide alongside residential installations.
Complete your Clearlight setup
A Clearlight sauna is the foundation of a complete home wellness practice, not the endpoint. Clearlight manufactures a full ecosystem of accessories, wellness devices, and cold therapy equipment designed to layer directly into sauna sessions or complement them. Most Clearlight sauna buyers add one or two of these products in the first year of ownership, and the full ecosystem is covered in detail in dedicated guides for each product category.
Clearlight saunas FAQ
How many Clearlight sauna models are there?
Twelve current Clearlight sauna models. Six Sanctuary Indoor full-spectrum models (Sanctuary 1, 2, 3, 5, C, Retreat), three Premier Indoor far-infrared-only models (IS-1, IS-2, IS-3), two Sanctuary Outdoor full-spectrum models (Outdoor 2, Outdoor 5), and the Curve Dome portable far-infrared sauna. Every model uses the same True Wave carbon-ceramic heater technology and meets Clearlight's below-0.8-milligauss EMF standard.
What is the difference between Clearlight Sanctuary and Premier saunas?
Sanctuary is Clearlight's full-spectrum infrared line — near infrared, mid infrared, and far infrared combined. Premier is Clearlight's far-infrared-only line at a more accessible price point. Both use Clearlight's True Wave heaters and deliver the same near-zero EMF performance. The decision comes down to whether you specifically want near-infrared wavelengths (Sanctuary) or whether excellent far infrared alone is sufficient (Premier). Read the full Sanctuary vs Premier comparison guide for side-by-side details.
Do I need an electrician to install a Clearlight sauna?
It depends on the model. Saunas that run on standard 120V/15A household outlets (Sanctuary 1, Premier IS-1, Premier IS-2) require no electrician. Saunas on 120V/20A outlets (Sanctuary 2, Premier IS-3) require a NEMA 5-20P receptacle — a different outlet type that may need an electrician depending on your existing wiring. Saunas on 240V circuits (Sanctuary 3, 5, C, Retreat, and both Outdoor models) require a dedicated 240V circuit installation by a licensed electrician. The Curve Dome runs on two standard 120V outlets with no electrical work.
How much does a Clearlight sauna cost?
Clearlight saunas are priced at the premium end of the infrared sauna market, reflecting the Lifetime residential warranty, clinical-grade EMF performance, True Wave heater technology, and eco-certified hardwood construction. Pricing varies by model, capacity, spectrum, and current promotional cycles. Clearlight sets minimum advertised pricing policies for authorized dealers, and Sauna Republic provides current pricing on request. Get pricing for the specific model you are considering.
What warranty do Clearlight saunas come with?
Every Clearlight indoor cabin sauna (Sanctuary and Premier) carries a Lifetime Residential warranty covering the entire sauna. Outdoor models (Sanctuary Outdoor 2 and Outdoor 5) carry the same Lifetime Residential warranty covering the entire sauna, with a 5-year cabin warranty reflecting the outdoor exposure. The Curve Dome carries a 7-year residential warranty. Commercial installations are covered under 5-year commercial warranties on the same components. All warranties cover the original retail purchaser.
Are Clearlight saunas HSA or FSA eligible?
Every Sauna Republic invoice includes a "Pay with Truemed" option. You click it, complete Truemed's health assessment, and if Truemed approves, the transaction completes with HSA/FSA funds. Eligibility depends on your individual health profile and HSA/FSA plan rules — Truemed verifies per customer on a per-purchase basis, not per product. Our HSA/FSA information page explains how the flow works end-to-end.
Are Clearlight saunas good for commercial installations?
Yes. Clearlight saunas are commonly specified into chiropractic offices, physical therapy clinics, wellness studios, day spas, recovery-focused gyms, and medical practices. The 5-year commercial warranty (matching residential components with a 5-year commercial coverage tier), clinical-grade EMF performance, and Dr. Raleigh Duncan's clinical heritage all contribute to the brand's positioning in professional settings. Sauna Republic handles commercial multi-unit pricing and dedicated project support for commercial installations.
Do I need to assemble a Clearlight sauna myself?
Clearlight cabin saunas are engineered for customer assembly — the cabin pieces snap together with integrated hardware and most indoor 1-to-3-person models can be assembled by two people in two to four hours. Larger 4-to-5 person indoor models and outdoor models take longer but follow the same assembly approach. If you prefer professional assembly, local handyman services can handle the job — most cabin saunas do not require specialized tools or electrician-grade skills beyond the 240V circuit installation (if your model requires one). The Curve Dome ships fully assembled.
How do I decide between Sanctuary 1 and Premier IS-1 for a single-person sauna?
The Sanctuary 1 and Premier IS-1 are Clearlight's two single-person indoor models, both running on standard 120V/15A household outlets. The Sanctuary 1 delivers full-spectrum infrared (near + mid + far) and includes the glass roof and double-door features. The Premier IS-1 delivers far infrared only and includes the ergonomic backrest as standard equipment. If you specifically want near-infrared wavelengths and the premium Sanctuary feature set, Sanctuary 1. If far infrared therapy at a more accessible price with the ergonomic backrest built in is the priority, Premier IS-1. Both are excellent single-person solo-session saunas for buyers with space for a permanent cabin installation.
Where can I buy Clearlight saunas?
Clearlight is sold through a network of authorized dealers — not retail stores. Sauna Republic is an authorized Clearlight dealer serving residential and commercial buyers across the United States. Authorized dealer status ensures you get the full manufacturer warranty, accurate technical guidance, and current Clearlight pricing. Unauthorized resellers cannot honor the warranty and typically have no access to current inventory or technical support.
