Quick Answer: Clearlight’s flagship Sanctuary line ships every model with True Wave full-spectrum heaters (near, mid, and far infrared together) and a limited lifetime warranty on wood, heaters, controls, electronics, and audio — one of the strongest coverage terms of any sauna brand we track. Pricing runs from $6,999 (Sanctuary 1, 1-person) to $9,899 (Sanctuary Retreat, mahogany), with a cheaper far-infrared-only Premier tier starting around $5,099. For most buyers the Sanctuary 2 at $7,399 is the sweet spot: two-person capacity, full spectrum heat, and the same lifetime warranty as the rest of the line, per Clearlight’s own 2026 pricing.
Clearlight has been building infrared cabins since 2003, and the Sanctuary series is what the brand is best known for — not because it’s the cheapest full-spectrum option (it isn’t; Golden Designs’ Reserve Edition undercuts it at $4,999), but because of how far the warranty reaches. Here’s how the four series actually compare, and where owner-reported issues mean the reputation doesn’t fully match the marketing.

1. Sanctuary 2 — Best Overall
Clearlight Sanctuary 2 Full Spectrum Infrared Sauna
- True Wave full-spectrum heaters standard — near, mid, and far infrared from the same panel, rated for roughly 30,000 operating hours.
- Limited lifetime warranty on wood, heaters, controls, electronics, and audio, plus 7 years of included technician labor, per Clearlight's residential terms.
- Built-in chromotherapy lighting, Bluetooth audio, and under-floor foot heater standard at every Sanctuary size.
Setting up delivery for a cabin this size takes planning — try Amazon Prime free for 30 days for free two-day delivery on the sauna towels, thermometers, and other accessories you’ll want on hand before the first session. The Sanctuary 2 is the size Clearlight itself sells most of: enough room for two adults without the extra $400 jump to the Sanctuary 3, and it carries the identical warranty and heater spec as every other model in the line.
2. Sanctuary 1 — Best Solo Use
Clearlight Sanctuary 1 Full Spectrum Infrared Sauna
- Plugs into a standard 120V household outlet — no dedicated circuit or electrician required, per Clearlight's spec sheet.
- Same True Wave full-spectrum heaters and lifetime warranty as the larger Sanctuary sizes.
- Smallest footprint in the Sanctuary line at 42.5"W x 48.25"D exterior, sized for one adult.
The Sanctuary 1 is the right call if you’re the only regular user and want full-spectrum heat without paying for space you won’t use. Comparing it against Sunlighten’s far-infrared-only Signature line? See our Sunlighten vs. Clearlight breakdown for the full warranty and pricing comparison.
3. Premier 1 — Best Budget Pick
Clearlight Premier 1 Far-Infrared Sauna
- Far-infrared-only heat — about $1,900 less than the equivalent Sanctuary 1, trading full spectrum for a lower entry price.
- Fewer built-in extras than Sanctuary (no chromotherapy or under-floor foot heater standard on most configurations).
- Still backed by Clearlight's residential lifetime warranty on core components.
Premier is worth considering if you specifically don’t need full spectrum — the near and mid infrared bands add engineering cost that far-infrared-only research on relaxation and sweat doesn’t strictly require. See our infrared vs. traditional sauna guide if you’re still deciding on infrared at all.
4. Outdoor 2 — Best Outdoor Model
Clearlight Outdoor 2 Full Spectrum Infrared Sauna
- Weatherproofed construction rated for exterior installation — Sunlighten currently sells no comparable outdoor-rated model.
- Same True Wave full-spectrum heaters and lifetime warranty as the indoor Sanctuary line.
- Outdoor 5 ($9,799) steps up to 5-person capacity for households wanting a shared backyard cabin.
If a dedicated outdoor cabin from a different brand family is more your budget, our best outdoor sauna guide covers barrel-style alternatives from Dundalk and Almost Heaven starting closer to $5,000.
Where Clearlight’s reputation doesn’t fully hold up
The lifetime warranty is real and among the strongest in the category, but it’s not the whole picture. Owner reviews aggregated across third-party sauna review sites report uneven heat distribution in some Sanctuary units — corner-to-corner variance up to roughly 30°F in isolated cases — and WiFi/app control issues that some owners say took 6 to 12 months to fully resolve through support. Neither issue is universal, and the warranty does cover electronics and controls, but it means the lifetime-coverage pitch sometimes gets tested in practice rather than staying theoretical. Compare that against Golden Designs, which doesn’t offer the same warranty depth but has a longer track record with fewer reported electronics complaints.
The bottom line
For most buyers, the Sanctuary 2 at $7,399 is the right pick — full-spectrum heat, two-person capacity, and Clearlight’s full lifetime warranty without the $2,500 premium of the Outdoor or Retreat models. Solo users should look at the Sanctuary 1 ($6,999), and anyone who doesn’t need near/mid infrared can save close to $1,900 by stepping down to the Premier 1 (~$5,099). Buyers specifically wanting an outdoor-rated cabin should go straight to the Outdoor 2 ($8,699), since indoor Sanctuary models aren’t weatherproofed for exterior use.
