| Choose if | Two or three people who share sessions and can run a dedicated 240 V, 15 A circuit to the spot. | A solo user with about 42.5 × 48.25 in of floor space who wants full-spectrum heaters running off a standard 120V, 15A outlet. |
| Main trade-off | You can't return it once it's opened, and the warranty terms, heater details and safety listing aren't published. | There's no published price, labor is covered for 7 years rather than for life, and the 14.6A draw leaves little headroom on a 15A circuit. |

| Exact variant | 3-person Full-Spectrum Infrared Sauna | 1-person indoor full-spectrum infrared cabin, mahogany (basswood also offered), 120V/15A plug-in |
| Dimensions | HigherDOSE now lists the 3-person exterior as 61 W × 41 D × 76.5 H in. Its interior is listed as 57 in (the dimension is unlabeled), 36.25 in deep and 70 in high, at about 580 lb. The maker's current exterior dimensions differ from the 71 W × 48 D × 77 H in reported by Garage Gym Reviews, which may describe another version. Confirm the exact unit and installation clearances before measuring your room. | Exterior 42.5 W × 48.25 D × 77 H in. Interior 37.5 W × 45.5 D × 72.5 H in. Bench 35.5 W × 21.75 D × 19 H in. It weighs 425 lb. If you build it into an enclosed space, Clearlight recommends leaving 4 in around the sauna. |
| Installation | It needs a dedicated 240 V, 15 A circuit. HigherDOSE rates it at 2,930 W with a NEMA 6-15P plug, so you'll need a matching NEMA 6-15 outlet. An upgraded cord is available on request. It ships separately, and you fit it yourself. The carrier leaves the sauna on a pallet, as far as it can get along the road or driveway. Delivery to a room of your choice costs extra, by quote from HigherDOSE's sauna sales team. Installation isn't included. No assembly time or manual is published, though the page embeds a "How to build" video. Garage Gym Reviews says its installers took about 7 hours. | It plugs into a standard 120 V, 15 A household outlet with a NEMA 5-15P plug. The product page doesn't say it needs a dedicated circuit. Shipping is advertised as free. The sauna arrives by freight with lift-gate service at a scheduled delivery appointment, and someone 18 or older must sign for it. Clearlight says two people usually assemble it in about 1 to 1.5 hours with a screwdriver and the included Allen wrench. Its FAQ says 1 to 3 hours. Clearlight offers installation service in some areas but doesn't state a price. |
| Materials | HigherDOSE describes the exterior as black mahogany and the interior as basswood. These are manufacturer descriptions, not independently verified species or emissions results. The finish and cabin-specific VOC testing remain unknown; the resource page's fabric test concerns the sauna blanket, not this cabin. | Mahogany or basswood. Clearlight calls it furniture-grade natural wood and notes that grain and color vary from cabin to cabin. |
| Warranty | The product page promises a limited 5-year residential warranty and a 1-year commercial warranty. HigherDOSE's warranty page has no sauna section, only one-year terms for nine other products. It doesn't publish what the 5 years covers, so heaters, controls, labor, parts shipping and transfer are all unclear. Ask for the written sauna warranty before you order. | Clearlight says its residential Limited Lifetime Warranty covers the entire sauna for as long as you own it. That means the heaters, control panels and electrical components, wood cabin, audio and chromotherapy lighting. Parts and shipping are covered for life, but labor isn't. The warranty page says labor is covered for an initial period without giving its length. The Sanctuary owner's manual, which lists Sanctuary 1, sets labor at 7 years for indoor home use in the US and Canada. The manual counts coverage from the purchase date. It also says the warranty can't be transferred without written consent from Sauna Works, which issues it. Commercial use falls under a 5-year warranty. The warranty page says registration is automatic when the sauna ships. The manual instead asks you to register within 30 days of purchase. |
| Returns | HigherDOSE's return policy gives Full Spectrum Saunas 30 days from delivery, but only if unopened and in the original packaging. Every approved return carries a 30% restocking fee, about $2,700 at the 3-person price. You also pay all return shipping. The 120-day money-back guarantee in the site banner doesn't cover saunas. The policy was last updated May 8, 2025. | Clearlight calls it a "30 Day Risk-Free Return Policy," but a return isn't free. You have 30 business days from receipt and need a return authorization (RMA). The sauna must be in new or like-new condition, with undamaged original packaging and all manuals. Clearlight deducts a 25% restocking charge and the original shipping charges. If the sauna shipped under a free or discounted shipping promotion, that means the actual freight cost. You also pay return shipping. Custom, private-label and non-standard models are non-refundable. Orders canceled before shipment are fully refunded. Concealed damage must be reported within 5 business days of delivery. |
