US price	$10,999Checked Oct 23, 2026 · Price details in the review	Price on requestChecked Oct 20, 2026 · Price details in the review
Three-year ownership estimate	$10,999 Incomplete known subtotal. Not included: installation, other annual costs, energy use.	$319.30 Incomplete known subtotal. Electricity assumption: $0.18/kWh. Not included: purchase price, installation, other annual costs.
Choose if	Two adults who can set the 970 lb cabin on a level, draining pad and run a new 240 V, 20 A circuit to it.	One person with a dedicated 120 V, 20 A circuit who wants red light and several infrared wavelengths in one cabin.
Main trade-off	The electrician and the pad cost extra. Warranty labor ends after 90 days, and an unpacked unit can't be returned.	Sunlighten publishes no price, and you can't return the cabin once the boxes are opened.
Key specifications	Heaters: 6 full-spectrum heaters (4 behind the backrests, 2 on the glass wall) and 3 far-infrared heaters (2 calf panels, 1 floor). The wattage of each heater isn't stated Electrical: 240 V, 4,800 W, 20 A. NEMA L6-20P twist-lock plug on a dedicated GFCI-protected circuit. Licensed electrician required Temperature and warm-up: Up to 170°F. Warm-up takes 15 to 20 minutes in mild weather Session guidance: Control range 90 to 170°F. The manual gives typical sessions of 20 to 45 min, with a 45 min maximum. After 2 hours of continuous use, it says to shut the sauna down for at least an hour Outdoor rating: Rated for year-round outdoor use. The roof isn't built to carry more than a foot of snow Weight: 970 lb assembled. The pad must support at least 1,500 lb Controls and extras: Digital control panel, app control over 2.4 GHz Wi-Fi, Bluetooth and USB audio, chromotherapy lighting, oxygen ionizer and a soft-close door	Heaters: 5 far-infrared, 4 mid-infrared and 3 near-infrared and red LED panels. Sunlighten says its PulseIQ platform controls the four wavelengths separately. Per-heater wattage isn't stated Red and near-infrared light: Sunlighten says the LED panels peak at 650 nm (red) and 880 nm (near-infrared) and deliver 1 to 3 mW/cm² to the skin. It says that's lower than dedicated LED devices. No independent measurement is given Electrical: 120 V, 18 A, 2,160 W per the assembly guide. Dedicated 120 V, 20 A circuit with a NEMA 5-20 outlet. 10 ft cord. Dual-band Wi-Fi (2.4 and 5 GHz) Inside and seating: 37.8 W × 35.6 D × 71.5 H in.

Leave 4 in to the walls and 6 in above Heat: Sunlighten says it warms about 1°F a minute and suggests 45 to 60 minutes of preheat. Its wellness programs aim for 120 to 130°F, and you can preheat to 130 to 140°F by hand. No top temperature is stated Controls: Built-in tablet and Sunlighten app to start, preheat (up to 60 minutes), schedule and adjust sessions. Six preset programs plus a custom one.

Two people assemble it, about 1 to 2 hours per Sunlighten's FAQ Safety listing: Sunlighten says its saunas are ETL-certified. The spec sheet shows an ETL mark (US and Canada) beside RoHS, CE and TÜV logos, with no file number Running cost: Sunlighten's owner's manual estimates $0.20 to $0.50 an hour. The 2,160 W figure is the electrical rating, and Sunlighten gives no average power draw Extras: Chromotherapy lights with a remote, ceiling speakers, CELLIANT heater covers and a ceiling vent Cleaning: Wipe the bench and floor after each use, wipe all wood weekly with Sunlighten's natural cleaner and wipe heater surfaces monthly. Clear dust from the power box heat sinks twice a year
Exact variant	2-person outdoor full-spectrum infrared cabin, Canadian red cedar interior, aluminum exterior, dedicated 240V / 20A circuit, without the optional red-light add-on	1-person installed infrared cabin with red light, eucalyptus or basswood
Dimensions	Exterior: 57 W × 51.5 D × 82.7 H in. Interior: 53.4 W × 47.2 D × 71.7 H in. It ships in one 65 × 32 × 89 in crate with a gross weight of 975 lb.	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.
Installation	It needs a dedicated 240 V, 20 A circuit with GFCI protection. The weatherproof NEMA L6-20R twist-lock receptacle must be within 6 ft of the cord exit, and 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. The owner's manual offers a free roof security cable kit, requested by email, to anchor the sauna, and it doesn't say at what wind speed the kit is needed. The sauna arrives palletized at the curb in one crate, and Sun Home says to set aside half a day and two or more people for assembly.	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.
Materials	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.	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.
Warranty	Cabinetry (benches, floor grates and heater cover frames) and heaters get a limited lifetime warranty that applies for up to seven years, which the terms give as their expected useful life. For the first 90 days after delivery, warranty service includes replacement parts, labor and shipping, and after that you pay shipping and labor. The exterior cabin and the controls (control panel and power box) get 3 years each, and LED lighting, glass doors and audio get 1 year. These terms cover residential purchases in the US on or after March 2, 2026, and 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. Not using the included cover doesn't by itself void it. Commercial use carries shorter terms.	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.
Returns	You can return an unused sauna in its original, unopened packaging within 30 days of delivery, but Sun Home doesn't accept uncrated, assembled or used saunas. It deducts a 25% restocking fee plus outbound and inbound shipping, even on free-shipping orders, and issues refunds within 21 days of receiving the return. Every cancellation carries a 3% fee. You can cancel an in-stock order within 24 hours, and after that a 25% restocking fee and possibly roundtrip shipping apply. Inspect the shipment before the delivery driver leaves.	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 cancel before it ships, email your sales representative, and the same fees may apply. 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.
Unresolved questions	What the electrician, receptacle and pad will cost at your site The wattage of each heater Average energy use per session Whether it carries an ETL, UL or CSA safety listing, and the file number if so The test method or report behind the <0.5 mG EMF figure Its wind rating, and when you need the roof security cable kit Whether liftgate service or delivery past the curb is available	The price, and which models the Sale ends 10/31/26 footnote covers A ship date or lead time for the Aspire, since the shipping page says the estimated ship date varies by model Whether any EMF measurement covers the Aspire, since the Vitatech report tested other models and the safety page's 0.5 mG figure gives no model or distance The ETL file number and which models it covers A top cabin temperature Average power draw once the cabin is up to temperature The minimum doorway width its panels and cartons need Whether the 7-year heater warranty covers the red and near-infrared LED panels Whether your local code requires GFCI protection, and what an electrician would charge The tablet's screen size, and whether there's an automatic shut-off Whether the sauna works without Wi-Fi, since the spec sheet lists dual-band Wi-Fi as required and Sunlighten doesn't say
