Choose if	Two people with a dedicated 120 V, 20 A circuit, about 51 × 46 in of indoor floor and a paved path for freight.	Two adults without indoor space who can set the 970 lb cabin on a level, draining pad and run a new 240 V, 20 A circuit to it.
Main trade-off	Opened saunas can't be returned, warranty labor is on you, and the panel magnets can affect pacemakers.	You pay for the electrician and the pad on top of the price, warranty labor and shipping end after 90 days, and you can't return it once it's unpacked.

Dimensions	Outside: 50.9 W × 45.9 D × 77.7 H in, including 2 in feet. Inside: 45.4 W × 39.9 D × 70.3 H in. The door opening is 28 in. The bench is 45.2 in wide and 20.3 in deep, 19.5 in off the floor. It weighs 541 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.	Exterior: 57 W × 51.5 D × 82.7 H in. Interior: 53.4 W × 47.2 D × 71.7 H in. The door opening is 24 in. The cabin weighs 970 lb assembled. It ships in one 65 × 32 × 89 in crate with a gross weight of 975 lb.
Installation	It needs a dedicated 120 V, 20 A circuit with a NEMA 5-20R outlet. Sunlighten rates it at 1,880 W and 15.67 A. The product page tells you to book an electrician so the outlet is ready, but doesn't mention GFCI protection. Under Sunlighten's warranty, a power strip, extension cord, converter or non-dedicated circuit voids coverage. So does placing it within 5 ft of a shower, bathtub or cold plunge. Sunlighten says its saunas aren't designed to be placed outdoors. If you put one outside anyway, its separately sold cover and plastic sheet must stay on, even during sessions, or the warranty is void. Freight needs a flat, paved surface up to your garage door. The carrier leaves the sauna on a pallet in the garage or on the driveway and can't take it up steps. A local agent calls to schedule delivery. It ships in two to three boxes of 130 lb each, and Sunlighten says to have at least two people to unpack. The Magne-Seal panels lock together without screws or nails. Sunlighten says two people take about 2 to 3 hours. Its support page links an owner's manual, spec sheet, assembly guide and power box guide, but those PDFs couldn't be opened for this review.	It needs a dedicated 240 V, 20 A circuit with GFCI protection. It also needs a weatherproof NEMA L6-20R twist-lock receptacle within 6 ft of the cord exit. Sun Home says a licensed electrician is required. The manual says not to plug it into a standard 120 V household outlet or share the outlet with other appliances. The 8 ft cord exits the roof at the back wall. The pad must be flat, level and draining, extend at least 6 in beyond the footprint and support at least 1,500 lb. Leave 4 to 6 in behind and beside the cabin, 20 to 24 in above the roof, and room for the door to swing fully open. The product page says to install it at least 5 ft from other electrical devices. Placing it within 5 ft of a water source that produces liquid or vapor voids the warranty. The owner's manual offers a free roof security cable kit, requested by email, to anchor the sauna. It doesn't say at what wind speed the kit is needed. The sauna arrives palletized at the curb in one crate. Sun Home says to set aside half a day and two or more people for assembly.
Materials	The outside has a limited-edition black finish that Sunlighten calls Obsidian. The inside is natural eucalyptus, which Sunlighten says is sustainably sourced. Plain eucalyptus costs the same, and basswood is $200 less. It comes with a CELLIANT heater cover.	The interior is Canadian red cedar. The exterior has what Sun Home calls aerospace-grade aluminum cladding, a stainless steel roof and double-pane black glass. A fitted all-weather cover is included.
Warranty	The product page shows a 7-year warranty badge. Sunlighten's warranty page groups Amplify with its other cabin saunas. For home use, the cabinet and heaters get 7 years. The cabinet includes the benches, 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 lighting has its own 1-year term. Commercial use gets 5 years on the cabinet and heaters and 1 year on everything else. The warranty's disclaimers say labor and technician costs aren't covered. You pay all freight, including on parts shipped for service. Coverage is for the original buyer only and ends if you sell the sauna. It's void on a power strip, extension cord, converter or non-dedicated circuit, or within 5 ft of a shower, bathtub or cold plunge. Sunlighten says its saunas aren't designed for outdoor use. Outside, the separately sold cover and its plastic sheet must stay on at all times. The sauna must be bought and put into use within a year of its manufacture date.	These terms cover residential purchases in the US on or after March 2, 2026. Cabinetry (benches, floor grates and heater cover frames) and heaters get a limited lifetime warranty. That coverage applies for up to seven years, which the terms give as their expected useful life. The exterior cabin and the controls (control panel and power box) get 3 years each. LED lighting, glass doors and audio get 1 year. For the first 90 days after delivery, warranty service includes replacement parts, labor and shipping. After that, you pay shipping and labor. Only the original purchaser is covered. Weather events, normal weathering, cosmetic damage and water exposure are excluded. Lacking a dedicated outlet, or placing the sauna within 5 ft of a water source, voids the warranty. The included cover is optional, and not using it doesn't by itself void the warranty. Commercial use carries shorter terms.
Returns	You have 30 days from delivery to start a return or exchange, and the sauna must be in its original, unopened packaging. Opened saunas can't be returned or exchanged. Returns, exchanges and cancellations may carry a 3% administrative fee and a $499 restocking fee for each Amplify sauna. Storage fees for re-routing the sauna and return shipping to the warehouse may also apply. Exchanges can add shipping back to you. If it hasn't shipped, you cancel by emailing your sales representative, or through Sunlighten's order portal if you don't have one. Refunds go to the original payment method once the sauna is received, inspected and restocked, with no stated timeframe. Sunlighten reserves the right to refuse a return, exchange or cancellation.	You can return an unused sauna in its original, unopened packaging within 30 days of delivery. Sun Home deducts a 25% restocking fee plus outbound and inbound shipping, even on free-shipping orders. It doesn't accept uncrated, assembled or used saunas. Every cancellation carries a 3% fee. You can cancel an in-stock order within 24 hours. After that, a 25% restocking fee and possibly roundtrip shipping apply. Refunds are issued within 21 days of Sun Home receiving the return. Inspect the shipment before the delivery driver leaves.
