| Choose if | Two or three people who share sessions and can run a dedicated 240 V, 15 A circuit to the spot. | Two adults with a 20 A outlet and about 60 × 56 in of floor space who'd rather have long warranty coverage than a published price. |
| Main trade-off | You can't return it once it's opened, and the warranty terms, heater details and safety listing aren't published. | You can't compare its cost upfront with listed-price cabins like the Sunlighten Amplify II, labor coverage ends after 7 years indoors, and a return costs 25% plus freight and the original shipping charge. |

| Exact variant | 3-person Full-Spectrum Infrared Sauna | 2-person full-spectrum infrared cabin, mahogany (basswood also offered), 120V / 20A 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. | Outside: 51.75 W × 47.75 D × 77 H in (listed as 51 3/4″ × 47 3/4″ × 77″). Inside: 46.5 W × 44.25 D × 72.5 H in. It weighs 450 lb. The owner's manual asks for at least 4 in of clearance on all sides for air circulation. The product page recommends 4 in around the sauna if it's built into an enclosed space. |
| 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 straight into a 120 V, 20 A wall receptacle with a NEMA 5-20P plug. It's rated at 18.83 A, close to the circuit's 20 A rating. Clearlight doesn't say you need a dedicated circuit or an electrician. The manual calls for a properly grounded 3-wire socket and advises against extension cords. It strongly recommends a GFCI in potentially wet locations, and asks for a dry, level surface with at least 4 in of clearance. The sauna ships by liftgate freight, with a scheduled delivery appointment. Clearlight's general assembly page says two people usually assemble it in about 1 to 1.5 hours, using a screwdriver and the included Allen wrench. Installation service is available in some areas, at no stated price. Outdoors, Clearlight requires its optional canvas cover, with the sauna on a deck or concrete pavers. |
| 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, which Clearlight describes as genuine, furniture-grade natural wood. It says the heaters combine ceramic and carbon. |
| 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 lifetime residential warranty covers the entire sauna for as long as you own it: the wood cabin, True Wave heaters, controls and electrical components, audio and chromotherapy lighting. Parts and shipping are covered for life. Labor is covered only for an initial period. The "Sauna Works Limited Lifetime Warranty" table in the owner's manual sets that at 7 years for indoor residential use (USA and Canada only). Outdoor residential use is covered only if you bought Clearlight's water-resistant cover with the sauna and kept it on. In that case, the manual limits cabin and labor coverage to 5 years. Commercial use carries a 5-year warranty. Clearlight's warranty page and manual differ on registration. The warranty page says it's automatic when the sauna ships. The manual says you must register within 30 days of purchase. The manual also says the warranty can't be transferred without Clearlight's written consent. |
| 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 returns aren't free. They're accepted within 30 business days of receipt, and you need a Return Merchandise Authorization. The sauna has to be in new or like-new condition, in undamaged original packaging with all manuals. The refund is the purchase price minus any original shipping charges and a 25% restocking charge. If the sauna shipped under a free or discounted shipping promotion, the actual original freight cost is deducted. You pay return shipping. Custom, private-label and non-standard models are non-refundable. You must open the boxes and inspect them for concealed damage within 5 business days of delivery. |
