Choose ifTwo 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.Two adults with a 20 A outlet and about 60 × 56 in of floor space who'd rather have long warranty coverage than a published price.
Main trade-offYou 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.You can't compare its cost upfront with listed-price cabins like the Sunlighten Amplify II, labor coverage ends after 7 years indoors, and a return costs 25% plus freight and the original shipping charge.

Exact variant2-person outdoor full-spectrum infrared cabin, Canadian red cedar interior, aluminum exterior, dedicated 240V / 20A circuit, without the optional red-light add-on2-person full-spectrum infrared cabin, mahogany (basswood also offered), 120V / 20A plug-in
DimensionsExterior: 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.Outside: 51.75 W × 47.75 D × 77 H in (listed as 51 3/4″ × 47 3/4″ × 77″). Inside: 46.5 W × 44.25 D × 72.5 H in. It weighs 450 lb. The owner's manual asks for at least 4 in of clearance on all sides for air circulation. The product page recommends 4 in around the sauna if it's built into an enclosed space.
InstallationIt 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.It plugs straight into a 120 V, 20 A wall receptacle with a NEMA 5-20P plug. It's rated at 18.83 A, close to the circuit's 20 A rating. Clearlight doesn't say you need a dedicated circuit or an electrician. The manual calls for a properly grounded 3-wire socket and advises against extension cords. It strongly recommends a GFCI in potentially wet locations, and asks for a dry, level surface with at least 4 in of clearance. The sauna ships by liftgate freight, with a scheduled delivery appointment. Clearlight's general assembly page says two people usually assemble it in about 1 to 1.5 hours, using a screwdriver and the included Allen wrench. Installation service is available in some areas, at no stated price. Outdoors, Clearlight requires its optional canvas cover, with the sauna on a deck or concrete pavers.
MaterialsThe 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.Mahogany or basswood, which Clearlight describes as genuine, furniture-grade natural wood. It says the heaters combine ceramic and carbon.
WarrantyThese 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.Clearlight says its lifetime residential warranty covers the entire sauna for as long as you own it: the wood cabin, True Wave heaters, controls and electrical components, audio and chromotherapy lighting. Parts and shipping are covered for life. Labor is covered only for an initial period. The "Sauna Works Limited Lifetime Warranty" table in the owner's manual sets that at 7 years for indoor residential use (USA and Canada only). Outdoor residential use is covered only if you bought Clearlight's water-resistant cover with the sauna and kept it on. In that case, the manual limits cabin and labor coverage to 5 years. Commercial use carries a 5-year warranty. Clearlight's warranty page and manual differ on registration. The warranty page says it's automatic when the sauna ships. The manual says you must register within 30 days of purchase. The manual also says the warranty can't be transferred without Clearlight's written consent.
ReturnsYou 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.Clearlight calls it a "30 Day Risk-Free Return Policy", but returns aren't free. They're accepted within 30 business days of receipt, and you need a Return Merchandise Authorization. The sauna has to be in new or like-new condition, in undamaged original packaging with all manuals. The refund is the purchase price minus any original shipping charges and a 25% restocking charge. If the sauna shipped under a free or discounted shipping promotion, the actual original freight cost is deducted. You pay return shipping. Custom, private-label and non-standard models are non-refundable. You must open the boxes and inspect them for concealed damage within 5 business days of delivery.
