Choose if	Two or three people who share sessions, with a dedicated 120 V, 20 A circuit and about 63 × 46 in of indoor floor.	Two adults with about 57 × 54 in of floor space and a lightly loaded 15 A outlet who want a near-infrared panel included at a published price.
Main trade-off	Opened saunas can't be returned, and the product page skips wattage, top temperature and a safety listing number.	The 1,780 W draw nearly fills a 15 A circuit, the panel has no published wavelength or output, and beyond the heater core, harness and wiring the warranty runs 10 years, with warranty labor at your expense.

Exact variant	3-person installed infrared cabin, eucalyptus/obsidian	2-person indoor infrared cabin, Indonesian mahogany, Tecoloy dual-wave mid/far-infrared heaters plus a standard 96-diode near-infrared LED panel, 120V/15A plug-in
Dimensions	Outside: 62.3 W × 45.9 D × 77.7 H in, including 2 in feet. Inside: 56.8 W × 39.9 D × 70.3 H in. The door opening is 28 in. The bench is 56.7 in wide and 20.3 in deep, 19.5 in off the floor. It weighs 642 lb. Sunlighten says it fits under a standard 8 ft ceiling and its panels fit through a standard 30 in doorway. The product page gives no clearance to leave around the cabin.	Outside: 47.25 W × 43.5 D × 77 H in. Inside: 45 W × 39.5 D × 71.5 H in. The manual asks for at least 5 in of clearance from walls on all sides, so plan on about 57.25 × 53.5 in of floor space. Health Mate doesn't state the weight or bench size.
Installation	It needs a dedicated 120 V, 20 A circuit and outlet. Sunlighten's FAQ says a power strip or converter voids the warranty. The warranty page also rules out extension cords and shared circuits. It asks for at least 5 ft between the sauna and a cold plunge, shower or bathtub. The product page suggests booking an electrician so the outlet is ready on build day. It doesn't list the wattage, amperage or outlet type. Freight delivery needs a flat, paved surface up to your garage door. The carrier leaves the sauna there on a pallet and can't carry it up steps. It comes in two to three mattress-sized boxes of 130 lb each. The Magne-Seal panels lock together without screws or nails. Sunlighten says two people take about 2 to 3 hours.	It plugs into a standard 120 V, 15 A outlet with a NEMA 5-15P plug, and the product page says "no electrician needed." The catch is the load. The 1,780 W rating works out to about 14.8 A at 120 V, which leaves the circuit little room for anything else. The manual says to confirm the breaker matches the sauna's rating and not to share the circuit with too many appliances. It also calls for a properly grounded three-wire outlet and strongly recommends a GFCI in potentially wet locations. The cabin must be freestanding (not built into a structure) on a level, dry surface. It ships crated on a pallet by freight, with lift-gate service and a scheduled appointment, typically in 7 to 12 business days. Standard curbside delivery is free. The product page lists inside delivery and white-glove delivery as quoted separately, and says extra fees may apply if the carrier needs special access or handling. According to the manual, the magnetic wall panels need no tools. The shipping page says two people can assemble it in 30 minutes or less. For outdoor use, the manual says it needs a cover and a spot under an awning or overhang.
Materials	It's eucalyptus in Sunlighten's black Obsidian finish. Plain eucalyptus costs the same, and basswood is $200 less. It comes with a CELLIANT heater cover. Sunlighten says its eucalyptus is sustainably sourced. It also says the glue on the tongue-and-groove boards is non-toxic and was third-party tested by Franklin International.	100% Indonesian mahogany. Health Mate notes that grain, tone and finish vary. The info sheet describes a wood interior and exterior with limited see-through glass. The handle is stainless steel.
Warranty	Sunlighten's warranty page groups Amplify with its other cabin saunas. For home use, the cabinet and heaters get 7 years, the controls 3 years, and the glass door and audio 1 year. Commercial use gets 5 years on the cabinet and heaters and 1 year on everything else. You pay the freight on parts shipped for service. A general disclaimer says coverage is for replacement parts only, not labor or technician costs. It sits right after the red light panel's terms, so it's unclear whether it applies to cabins. The warranty covers only the original buyer and ends if you sell the sauna. It's void on a power strip, extension cord, converter or shared circuit, or within 5 ft of water. Sunlighten says its saunas aren't designed to be placed outdoors. If you put one outside anyway, its cover (sold separately) has to stay on at all times, even during sessions. The sauna must also be bought and put into use within a year of its manufacture date. The page shows no version or effective date.	The product page markets a "Limited Lifetime Warranty," but the same page's FAQ says only that Health Mate saunas come with a 10-year warranty on wood. The owner's manual is more specific. Its warranty section is headed "10-Year Limited Warranty" and applies to saunas bought after 2024. It gives lifetime coverage to the heater core, harness and wiring. Coverage is 10 years on the cabin and frame, paneling, flooring, door and glass, handles, electronic controls and wiring, interior and exterior lighting, interior audio, and labor of factory-installed components. A second, shorter column of 1 to 5 years applies to what the manual defines as commercial use. Despite that labor row, the same terms say labor to replace cabin, frame, hardware and component parts isn't covered. All warranty labor must be done by the customer or a contractor, at the customer's expense. You pay shipping on parts in both directions, and removal and reinstallation costs are excluded. A claim requires timely registration. The warranty can't be assigned or transferred unless Health Mate approves. Upgrades, options, parts and accessories follow their own manufacturer's warranty, and the near-infrared LED panel isn't named. The coverage table has no outdoor column, so it doesn't address outdoor placement, which the manual allows with a cover. Health Mate's warranty page words the lifetime offer as applying to new full-size saunas purchased in 2025. Its warranty sheet is titled "Limited Warranty."
Returns	Non-custom saunas like Amplify can be returned or exchanged within 30 days of delivery, but only in the original, unopened packaging. Opened saunas can't be returned or exchanged. Charges can include a 3% administrative fee, a $499 restocking fee, storage fees and return shipping to the warehouse. Cancelling before it ships can cost the 3% fee, plus storage fees if the sauna has to be re-routed. Sunlighten reserves the right to refuse a return, exchange or cancellation. It refunds to your original payment method after it inspects and restocks the sauna.	Health Mate accepts returns within 30 business days of receipt, with a return authorization (RMA) number. The sauna must be in new or like-new condition, in undamaged original packaging with all manuals. The catch is cost. The refund is reduced by a 20% restocking charge (about $1,060 at list price) and any original shipping charges. You also pay return shipping. Custom, private-label and non-standard models are non-refundable. An order canceled before shipment is fully refunded. After shipment, a cancellation is handled as a return. The returns policy gives 5 business days to inspect for concealed damage. But the shipping page says damage must be noted on the delivery receipt and reported within 1 day (24 hours) of delivery.
Unresolved questions	The cabin's rated wattage and amperage, and so its running cost The maximum cabin temperature Which outlet type it needs and whether GFCI protection is required How much clearance to leave around the cabin Whether the warranty's no-labor line covers cabin saunas or only the red light panel What the owner's manual and power box installation guide require, since those PDFs couldn't be opened Whether an ETL listing covers this exact model, and its file number What the linked EMF test measured, on which models and at what distance Carton weights, since two to three boxes of 130 lb each don't add up to 642 lb Whether the $6,999 sale price outlasts the October 14 event	Cabin and crate weight, bench dimensions, and heater count and wattage by location Near-infrared panel wavelength, irradiance and wattage How a "9-color" panel relates to near-infrared output, since near-infrared itself isn't visible Whether the near-infrared panel runs separately from the heaters Whether the lifetime offer, worded for 2025 purchases on the warranty page, applies to 2026 orders Whether the LED panel is covered by the warranty How the 10-year labor row fits the manual's statement that warranty labor is at the customer's expense Which wattage figure (1,780 W or 1,810 W) is correct Prices of inside delivery, white-glove delivery and the promo savings behind the offer form Listing number and model scope behind the Intertek ETL mark Whether any app or smart control exists. The comparison page tags Enrich 2 as Smart without defining it and lists App Control only for Inspire models. The same page's $5,300 Classic Enrich Series card says "Doesn't have smart features"
