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 (assembled): 50.9 W × 45.9 D × 77.7 H in. Inside: 45.4 W × 39.9 D × 70.3 H in. It 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.
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 needs its own dedicated 120 V, 20 A circuit with GFCI protection, and the owner's manual says a licensed electrician should install it. 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, and the 10 ft power cord exits the back-left of the roof, so don't use power strips, extension cords or converters. The cabin is for indoor use only, away from rain, snow, high humidity and liquids. Sun Home says the Magne-Seal panels assemble indoors without special tools, and the manual says assembly takes two or more people and gives no time. Installation that ignores the instructions or electrical requirements voids the warranty, per Sun Home's warranty FAQ.
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.	Kiln-dried eucalyptus. Sun Home says it uses low-VOC materials throughout, but shows no emissions test or certification.
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.	Sun Home's owner's manual gives 7 years on cabinetry and heaters, 3 years on controls and 1 year on glass and audio. For orders placed on or after March 2, 2026, labor and all shipping charges are covered for the first 90 days only, and after that you pay shipping and labor. The product page shows a "7-Year Warranty," and a site-wide menu advertises a "Limited Lifetime Warranty" on most models without saying whether it applies to this one. Coverage is for the original owner only, with proof of purchase. Sun Home's warranty FAQ says the limited lifetime coverage on cabinetry and heaters is residential only and lasts up to seven years. Exclusions include moisture and water exposure, pests and improper installation. That includes skipping the dedicated outlet or placing the sauna within five feet of water that produces liquid or vapor. Commercial buyers get separate terms.
Returns	You have 30 days from delivery to return it, but only while it's unopened in its original packaging. Opened saunas can't be returned or exchanged. Fees can include a 3% administrative fee and a $499 restocking fee for each mPulse sauna. They can also include storage fees, return shipping to the warehouse and shipping back to you on an exchange.

To return it, email your sales representative for an authorization, or Sunlighten's logistics team if you have none. Sunlighten then schedules the pickup and refunds your original payment method after it inspects and restocks the sauna. Sunlighten reserves the right to refuse a return, exchange or cancellation.	You can return the sauna within 30 days of delivery only if it's unused and in its original, unopened packaging. Sun Home won't take back an uncrated, assembled or used sauna. It deducts a 25% restocking fee plus outbound and inbound shipping from the refund, even during free-shipping promotions, and issues the refund within 21 days of receiving the return. Every cancellation carries a 3% fee per product. You can cancel an in-stock order within 24 hours of placing it, and after that a 25% restocking fee and possibly roundtrip shipping apply. Sun Home asks you to inspect the shipment before the delivery driver leaves.
