| 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. | One person with a dedicated 120 V, 20 A circuit and about 38 × 40 in of indoor floor. |
| 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. | You can't return it once the boxes are opened, and the warranty doesn't pay for labor. |

| 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. | It needs a dedicated 120 V, 20 A circuit and outlet.

The warranty page also rules out extension cords and non-dedicated circuits. The same page requires at least 5 ft between the sauna and a cold plunge, shower or bathtub. The product page doesn't say whether you need an electrician or GFCI protection. It points you to the spec sheet for electrical details. Sunlighten's support page links an owner's manual, spec sheet, assembly guide and power box installation guide. Those PDFs couldn't be opened for this review. Freight delivery goes to a garage or flat, paved driveway. 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, and you need at least two people to unpack and carry in the panels. The Magne-Seal panels lock together without screws or nails. Sunlighten says two people take about 2 to 3 hours. |
| 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.

| 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." | Sunlighten's warranty page covers its mPulse, Signature and Amplify cabins under one set of terms. For home use, the cabinet and heaters get 7 years. The cabinet includes the bench, floor grates and heater cover frames. The controls (in-sauna tablet, control pad and power box) get 3 years. The glass door and audio get 1 year, and chromotherapy has a separate 1-year warranty. Commercial use gets 5 years on the cabinet and heaters and 1 year on everything else. It covers replacement parts only, not labor or technician costs. You pay the freight on parts shipped for service. It covers only the original buyer and ends if you sell the sauna. It's void on a power strip, extension cord, converter or non-dedicated circuit. It's also void within 5 ft of a shower, tub or cold plunge. Sunlighten's contraindications page adds that repairs attempted without consulting Sunlighten void it. Sunlighten says its saunas aren't designed for outdoor use. Outside, the separately sold sauna cover 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. |
