Two or three people who share sessions, with a dedicated 120 V, 20 A circuit and about 63 × 46 in of indoor floor.
Main trade-off	No electrical safety listing is named, labor and shipping are covered for just 90 days, and returns exclude opened cabins and cost 25% plus freight both ways.	Opened saunas can't be returned, and the product page skips wattage, top temperature and a safety listing number.

Exact variant	2-person indoor full-spectrum infrared cabin, eucalyptus, 4 far-infrared plus 2 full-spectrum heaters, 120 V, 1,880 W, dedicated 20 A circuit	3-person installed infrared cabin, eucalyptus/obsidian
Dimensions	Outside (assembled): 50.9 W × 45.9 D × 77.7 H in. Inside: 45.4 W × 39.9 D × 70.3 H in. The door opening is 28 in, and the bench is 45 in wide and 19.5 in high. It weighs 541 lb assembled and ships in cartons up to 14 × 51 × 76 in. You need at least 4 in of clearance at the sides and back, and 12 in above the roof. The manual, citing the Installation Guide, gives 6 in behind. Sun Home says a 7 × 6 ft room with an 8 ft ceiling fits either Equinox size.	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.
Installation	It needs its own dedicated 120 V, 20 A circuit with GFCI protection. That can be a GFCI breaker, a GFCI outlet or a dual-function AFCI/GFCI breaker (check local code). The 5-20P plug needs a NEMA 5-20R receptacle. Don't use power strips, extension cords or converters. The owner's manual says to have a licensed electrician install the dedicated circuit. The 10 ft power cord exits the back-left of the roof. It's for indoor use only, away from rain, snow, high humidity and liquids. Leave at least 4 in at the sides and back (6 in behind, per the Installation Guide) and 12 in overhead. Sun Home says its Magne-Seal panels assemble indoors without special tools. The manual says assembly takes two or more people. No assembly time is stated. According to Sun Home's warranty FAQ, installation that doesn't follow the instructions or electrical requirements, such as a dedicated outlet, voids the warranty. So does placing the sauna within five feet of a source of water that produces liquid or vapor.	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.
Materials	Kiln-dried eucalyptus. Sun Home says it uses low-VOC materials throughout, but shows no emissions test or certification.	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.
Warranty	The product page shows a "7-Year Warranty". A site-wide menu advertises a "Limited Lifetime Warranty" on most models but doesn't say whether it applies to this one. The owner's manual gives 7 years on cabinetry and heaters and 3 years on controls. Glass and audio get 1 year. Coverage is for the original owner only, with proof of purchase. Sun Home's warranty FAQ says limited lifetime coverage for cabinetry and heaters is for residential use only and applies for up to seven years. For orders placed on or after March 2, 2026, labor and all shipping charges are covered for the first 90 days. After that, you pay shipping and labor. Exclusions include moisture and water exposure, pests, and improper installation, including not using a dedicated outlet. Placing the sauna within five feet of any source of water that produces liquid or vapor is also excluded. Commercial buyers get separate terms.	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.
Returns	You can return the sauna within 30 days of delivery only if it's unused and in its original, unopened packaging. Sun Home deducts a 25% restocking fee plus outbound and inbound shipping from the refund, even during free-shipping promotions. It won't take back an uncrated, assembled or used sauna under any circumstances. Refunds are issued within 21 days of Sun Home receiving the return. Every cancellation carries a 3% fee per product. You can cancel an in-stock order within 24 hours of placing it. After that, a 25% restocking fee and possibly roundtrip shipping apply. Sun Home asks you to inspect the shipment before the delivery driver leaves.	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.
Unresolved questions	The wattage of each far-infrared wall heater Average power use during a session Whether any electrical safety listing (such as ETL or UL) covers this model How Sun Home measured its under 0.5 mG EMF figure How long assembly takes The delivery timeline Whether the sale price will last	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
