The Clearlight Sanctuary 2 vs Sanctuary 3 decision is the most common size question among serious infrared sauna buyers in 2026 — and it is simpler than most comparison articles make it. Both the Sanctuary 2 and the Sanctuary 3 use identical True Wave full-spectrum infrared heating technology, identical EMF shielding, identical construction quality, and identical lifetime warranty coverage. The difference is entirely in size and capacity. The Sanctuary 2 is the two-person specification — the correct choice for couples, solo buyers who want extra space, and rooms where footprint matters. The Sanctuary 3 is the three-person specification — the correct choice for families, buyers who want maximum bench space for lying flat during sessions, and rooms that can accommodate a larger footprint. Understanding which size serves your actual use case is the only decision this comparison requires.

What the Clearlight Sanctuary Series Is
Before comparing the Sanctuary 2 and Sanctuary 3 specifically, it helps to understand where the Sanctuary Series sits in the Clearlight lineup and why it's the specification most serious home sauna buyers end up choosing.
Clearlight offers three main product categories: the Premier Series (far-infrared only, most affordable), the Sanctuary Series (full-spectrum infrared, premium), and Outdoor models. The Sanctuary Series is the full-spectrum specification — the correct choice for buyers who want near, mid, and far infrared wavelengths delivered simultaneously in every session. The True Wave heater technology uses a patented combination of carbon fiber panels and ceramic heating elements — carbon for broad, even heat distribution across the full cabin surface, ceramic for intensity and raw heating power.
The Clearlight brand was acquired by Jacuzzi in 2021 — a development that meaningfully strengthens the long-term warranty and service picture. A lifetime warranty from a Jacuzzi-backed brand is a different proposition from a smaller standalone manufacturer, and for a $6,000–$9,000 home installation, that backing matters.
Both the Sanctuary 2 and Sanctuary 3 use the same True Wave full-spectrum heaters, the same EMF shielding technology producing under 1 mG at body level, the same lifetime warranty, and the same construction quality. The only difference is size. For the complete Clearlight brand comparison against Sunlighten, see our Clearlight vs Sunlighten 2026 guide.

The Clearlight Sanctuary 2 — The Two-Person Specification
Capacity: 2 persons | Interior: 44.5"W x 36"D x 72.5"H | Electrical: 120V/20A | Warranty: Lifetime
The Clearlight Sanctuary 2 is the most popular Clearlight configuration — the two-person full-spectrum infrared sauna that represents the standard home sauna suite specification for couples or solo buyers who want a dedicated sauna room without the footprint of a larger unit. At 44.5 inches wide and 36 inches deep, the Sanctuary 2 is the most space-efficient specification in the Clearlight Sanctuary lineup and the easiest to integrate into a dedicated room, basement, or wellness space without major renovation.
The 120V/20A electrical requirement is the most important practical specification for buyers evaluating installation — a standard dedicated circuit available in most homes without a panel upgrade, making the Sanctuary 2 the most straightforward installation in the Clearlight lineup. The two bench positions provide comfortable seating for two adults simultaneously, with the chiropractor-designed ergonomic backrest and reversible flat/ergonomic bench that are standard across the Sanctuary Series.
The True Wave heater panels deliver full-spectrum infrared — near-infrared for cellular repair and photobiomodulation, mid-infrared for circulation and muscle recovery, and far-infrared for deep tissue heating and cardiovascular response. EMF readings at body level are consistently under 1 mG. Available in Western Red Cedar and North American Basswood — cedar for the traditional aromatic sauna aesthetic, basswood for buyers who prefer a lighter, more neutral interior. The dual digital control panels, LED chromotherapy lighting, built-in Bluetooth audio, tablet cradle in the door handle, and glass roof are all standard.
For solo buyers, the Sanctuary 2 provides generous extra space — enough to lie flat on the bench for a full reclined session, which many buyers find more comfortable than the more confined single-person Sanctuary 1 specification. For couples, it provides a shared session experience that the Sanctuary 1 cannot accommodate.
Choose the Sanctuary 2 if:
You want the standard two-person sauna specification for a couple or solo buyer with extra space
Your installation space has a footprint limit — the Sanctuary 2 is 22 inches narrower than the Sanctuary 3
120V electrical is your preferred installation — no panel upgrade required
The two-person capacity is sufficient for your household's daily use
You want the most space-efficient Sanctuary Series specification
The honest trade-off: The Sanctuary 2's bench dimensions — 44" x 20" — are adequate for seated sessions but limit lying-flat options for taller buyers. The Sanctuary 3's 66-inch bench provides full-length reclining for most adults. For buyers who want to lie flat during sessions, the Sanctuary 3 is the more comfortable long-term specification.
The Clearlight Sanctuary 3 — The Three-Person Specification
Capacity: 3 persons | Interior: 66.5"W x 45.5"D x 72.5"H | Electrical: 120V/20A | Warranty: Lifetime
The Clearlight Sanctuary 3 is the three-person specification — the correct choice for families, buyers who want maximum bench space for lying flat, and households where more than two people will use the sauna regularly. At 66.5 inches wide and 45.5 inches deep, the Sanctuary 3 is 22 inches wider and nearly 10 inches deeper than the Sanctuary 2 — a meaningful increase in interior space that changes the daily use experience in ways beyond simple headcount.
The 66-inch bench length is the Sanctuary 3's most significant practical advantage over the Sanctuary 2. At 66 inches, most adults can lie fully flat on the bench during a session — a reclined position that many infrared sauna practitioners find more effective for full-body heat exposure and more comfortable for extended sessions. The Sanctuary 2's 44-inch bench accommodates seated and semi-reclined positions but not full-length reclining for adults over approximately 5'6". For buyers whose practice includes extended reclined sessions, the Sanctuary 3's bench length is the specification that matters most.
The Sanctuary 3 also runs on 120V/20A — identical to the Sanctuary 2 — which means the electrical installation is equally straightforward despite the larger cabin size. This is a meaningful advantage over some competing three-person saunas that require 240V. The Sanctuary 3's 580-pound weight requires careful consideration of floor load capacity and delivery access — confirm both before purchasing.
For the longevity lab buyer who uses the sauna as a daily recovery anchor and wants maximum session flexibility — lying flat, different positions throughout the session, occasional shared sessions with family — the Sanctuary 3 is the specification that accommodates the full range of practice without compromise.
Choose the Sanctuary 3 if:
You want to lie flat during sessions — the 66-inch bench accommodates most adults fully reclined
Three or more household members use the sauna regularly
Your installation space can accommodate the larger 66.5" x 45.5" footprint
Maximum session flexibility — seated, reclined, varied positions — is a priority
The additional price premium over the Sanctuary 2 is within budget
The honest trade-off: The Sanctuary 3 is wider and deeper than the Sanctuary 2 — verify your installation space can accommodate the full footprint including clearance on all sides before purchasing. At approximately 580 pounds it is significantly heavier than the Sanctuary 2's 450 pounds — confirm floor load capacity and delivery access. The price is higher than the Sanctuary 2 — contact Clearlight for current pricing on both models.
The Size Question: Which Fits Your Space and Practice?
The Clearlight Sanctuary 2 vs Sanctuary 3 decision is ultimately a size decision — not a technology decision. Here is the practical framework:
Choose the Sanctuary 2 if your primary use is: Solo daily sessions with occasional shared use, installation in a dedicated room with limited floor space, or a couple who sessions together regularly without needing full-length reclining.
Choose the Sanctuary 3 if your primary use is: Daily sessions that include lying flat or fully reclined positions, family use with three or more regular users, or any buyer who wants maximum session flexibility and can accommodate the larger footprint.
The floor space reality: The Sanctuary 2 requires approximately 4 ft x 3 ft of floor space plus clearance. The Sanctuary 3 requires approximately 6 ft x 4 ft of floor space plus clearance. Measure your intended installation space carefully before deciding — the 22-inch width difference is significant in a standard room.
The price reality: Clearlight does not publish prices publicly — contact infraredsauna.com for current pricing on both models. The Sanctuary 3 carries a meaningful price premium over the Sanctuary 2. For buyers whose budget is the determining factor, the Sanctuary 2 delivers identical infrared performance at a lower price.
Vapour & Stone Verdict
Choose the Clearlight Sanctuary 2 if the priority is the most space-efficient two-person Clearlight specification — 44.5" x 36" footprint, 120V electrical, identical True Wave full-spectrum performance and lifetime warranty at the lower price point. The correct specification for couples and solo buyers whose installation space has a footprint limit.
Choose the Clearlight Sanctuary 3 if the priority is maximum bench space for lying flat, three-person capacity, and the session flexibility that the 66-inch bench provides. At 66.5" x 45.5" with the same 120V electrical requirement and identical True Wave performance, it is the specification for buyers who want the full Clearlight experience without size constraints.

Frequently Asked Questions: Clearlight Sanctuary 2 vs Sanctuary 3
What is the difference between the Clearlight Sanctuary 2 and Sanctuary 3? Size and capacity only. The Sanctuary 2 seats two adults at 44.5" wide with a 44-inch bench. The Sanctuary 3 seats three adults at 66.5" wide with a 66-inch bench — long enough for most adults to lie fully flat. Both use identical True Wave full-spectrum infrared heaters, identical EMF performance under 1 mG, identical 120V electrical requirements, and the same lifetime warranty.
Can one person use the Clearlight Sanctuary 3? Yes — many buyers choose the Sanctuary 3 specifically for solo use because the 66-inch bench allows full-length reclining during sessions. The larger interior also provides more space for movement, different positions, and accessories like a yoga mat or recliner add-on.
Does the Clearlight Sanctuary 3 require 240V? No — the Sanctuary 3 runs on 120V/20A, identical to the Sanctuary 2. This makes it one of the few three-person infrared saunas available that can be installed on a standard dedicated household circuit without a panel upgrade.
