Main trade-off	Sunlighten publishes no price, and you can't return the cabin once the boxes are opened.	The lifetime warranty covers only the heater core, harness and wiring. Health Mate lists two different power draws, so check the circuit before you share it.	You can't return it once the boxes are opened, and the warranty doesn't pay for labor.

Exact variant	1-person installed infrared cabin with red light, eucalyptus or basswood	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	1-person installed far-infrared cabin, eucalyptus
Dimensions	Outside: 43.6 W × 41.6 D × 79 H in, including 2 in feet. Inside: 37.8 W × 35.6 D × 71.5 H in. The bench is 37.8 in wide and 21.7 in deep, 20.2 in off the floor. It weighs 463 lb in eucalyptus and 432 lb in basswood. Sunlighten recommends 4 in to the walls and 6 in above the cabin. Sunlighten gives no minimum doorway width and asks you to measure doorways and hallways before you buy.	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, which makes about 57.25 × 53.5 in of floor space. Health Mate doesn't state the weight or bench size.	Outside: 37.8 W × 39.8 D × 77.7 H in, including 2 in feet. Inside: 32.2 W × 33.6 D × 70.3 H in. The door opening is 28 in, and the door swings outward to the right. Sunlighten's spec sheet recommends 4 in between the sauna and the walls and 12 in above it. The manual's FAQ asks for 8 to 12 in around the back and sides and at least 8 in behind so the electronics can cool, so leave the larger gap. The cabin fits under a standard 8 ft ceiling, and its panels fit through a standard 30 in doorway.
Installation	It needs a dedicated 120 V, 20 A circuit and outlet with a NEMA 5-20 plug. Sunlighten's assembly guide rates it at 120 V, 18 A and 2,160 W. The 10 ft cord exits at the back left of the floor and must plug straight into the wall. The assembly guide says to add a GFCI or dual-function breaker only if your local code requires one. The spec sheet says dual-band Wi-Fi (2.4 and 5 GHz) is required, while the product page says recommended. Freight goes to a garage or a flat, paved driveway, where the carrier leaves it on a pallet and can't carry it up steps. You need two people to unpack and assemble it, which Sunlighten's FAQ puts at 1 to 2 hours, and professional installation isn't required.	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. Health Mate's product page lists 1,780 W (about 14.8 A at 120 V) and its info sheet 1,810 W (about 15.1 A). A 15 A circuit carries little else, so ask Health Mate before you share it. The manual says to match the breaker to the sauna's rating, use a grounded three-wire outlet and strongly recommends a GFCI in potentially wet locations. The cabin must stand freestanding on a level, dry surface, and for outdoor use the manual calls for a cover and a spot under an awning or overhang. It ships in boxes on a single pallet by freight, with lift-gate service and a scheduled appointment, in a typical 7 to 12 business days. Curbside delivery is free, inside and white-glove delivery are quoted separately, and extra fees may apply if the carrier needs special access. The magnetic wall panels need no tools, and the shipping page says two people can assemble it in 30 minutes or less.	It needs a dedicated 120 V, 20 A circuit with a NEMA 5-20R outlet (5-20P plug). Plug it straight into the wall, not a power strip, extension cord or converter. Sunlighten's manual says a certified electrician should install the dedicated outlet, and that failing to do so voids the warranty. It also says to put a GFCI or dual-function breaker on the circuit, so check your local code. Freight goes to a garage or flat, paved driveway, where the carrier leaves a pallet and can't carry it up steps. It comes in two to three mattress-sized boxes of 130 lb each, and at least two people must carry in the panels. The Magne-Seal panels lock together without screws or nails, and Sunlighten says two people take about 2 to 3 hours.
Materials	Sunlighten says each sauna is built from sustainably sourced eucalyptus with natural variation in tone and grain. Its spec sheet also lists basswood. It lists kiln-dried wood, thick insulation, a glass front door and side glass, and CELLIANT fabric covers over the heaters on the interior walls. Its safety page calls the glue non-toxic, citing testing by Franklin International.	100% Indonesian mahogany. Health Mate notes that grain, tone and finish vary. The handle is stainless steel.	Eucalyptus, which Sunlighten says is sustainably sourced, with natural variation in tone and grain. Basswood was marked not available. Obsidian is offered on the same page at no extra cost. It comes with a CELLIANT heater cover. Sunlighten says the glue is non-toxic, citing third-party testing by Franklin International.
Warranty	Sunlighten's warranty page gives the cabinetry and heaters 7 years for home use, and one set of terms covers its mPulse, Signature and Amplify cabins. Coverage is for replacement parts only, with no labor or technician costs. You pay freight on parts shipped for service, and the page excludes costs or freight for parts shipped more than 90 days after delivery. Controls (tablet, control pad and power box) get 3 years, the glass door and audio get 1 year. Chromotherapy and the Blaupunkt sound system carry a separate 1-year manufacturer's warranty. Commercial use gets 5 years on the cabinetry and heaters and 1 year on controls, glass and audio. It covers only the original buyer and ends if you transfer ownership, and the sauna must be bought and put into use within a year of its manufacture date. It's void if the sauna is altered, misused or exposed to water. It's also void on a power strip, extension cord, converter or non-dedicated circuit. The same goes for a spot within 5 ft of a shower, tub or cold plunge, or a repair attempted without consulting Sunlighten. Sunlighten says its saunas aren't designed for outdoor use, and outdoors the separately sold cover must stay on at all times, even during sessions. The page doesn't say whether the red and near-infrared LED panels count as heaters.	Health Mate's owner's manual gives lifetime coverage to the heater core, harness and wiring only. Most other parts get 10 years for saunas bought after 2024. That list covers the cabin and frame, paneling, flooring, door and glass, handles, electronic controls and wiring, lighting and interior audio. The product page markets a "Limited Lifetime Warranty," but its FAQ says only that Health Mate saunas come with a 10-year warranty on wood. The 2025 warranty sheet, the warranty page and the manual's coverage table list 10 years of labor, but the manual's warranty clause says required labor for replacing parts isn't covered, so get the labor terms in writing before you buy. Commercial use gets 1 to 5 years. Removal and reinstallation costs are excluded, and you pay parts shipping both ways. A claim requires timely registration, and the warranty can't be transferred unless Health Mate approves. The near-infrared LED panel isn't named, and upgrades, options and accessories follow their own maker's warranty. The coverage table has no outdoor column, though the manual allows outdoor placement with a cover.	Sunlighten's warranty covers replacement parts only, not labor or technician costs, and you pay all freight, including on parts shipped for service. For home use, the cabinet and heaters get 7 years. The cabinet includes the bench, floor grates and heater cover frames. Controls get 3 years, and the glass door and audio get 1 year. Commercial use gets 5 years on the cabinet and heaters and 1 year on everything else. Coverage is for the original buyer only and ends if you sell the sauna. The sauna must be bought and put into use within a year of its manufacture date. It's void on a power strip, extension cord, converter or non-dedicated circuit, within 5 ft of a shower, tub or cold plunge, or after unauthorized repairs. Sunlighten says its saunas aren't designed for outdoor use, and outdoors the separately sold cover has to stay on at all times.
