The verdict

Sanctuary 1 is a one-person full-spectrum infrared cabin that Clearlight says plugs into a standard 120V, 15A outlet. Its residential lifetime warranty covers parts and shipping. The catch: the price is quote-only, and a return costs a 25% restocking charge plus shipping.

The trade-off

There's no published price, labor is covered for 7 years rather than for life, and the 14.6A draw leaves little headroom on a 15A circuit.

About this price

Clearlight's product page listed no price on Oct 13, 2026. It showed a "Get Pricing" quote button, a "Save $600" Early Black Friday Sale banner and free shipping. It also showed financing offers: $999 down with 18-month financing, and payments as low as $138 per month. None of these gives a list price, so no price is recorded.

A GOOD FIT FOR

A solo user with about 42.5 × 48.25 in of floor space who wants full-spectrum heaters running off a standard 120V, 15A outlet.

A solo user with about 42.5 × 48.25 in of floor space plus clearance, and an available 120 V, 15 A outlet
You want front-wall full-spectrum heaters without a 20 A or 240 V circuit (the product page calls for neither)

THINK TWICE IF

You want a published price to compare before contacting sales
More than one person at a time, since Clearlight says it's built for one adult
Anyone who might need to return it: returns carry a 25% restocking charge plus shipping costs

What still needs checking

The current quoted price, and whether the Save $600 promotion applies
Whether the owner's manual or spec sheet recommends a dedicated circuit (the linked spec sheet couldn't be opened)
Whether the red light therapy upgrade needs a bigger circuit. Clearlight's FAQ says add-ons may require a circuit upgrade, typically from 15 A to 20 A or from 20 A to 30 A, but doesn't name models
Whether the manual's 7-year labor term is current, since the warranty page gives no length
Number and wattage of the far-infrared heaters
Which models and components the claimed ETL and CE certification covers
Delivery timeline

Before you buy

InstallationIt plugs into a standard 120 V, 15 A household outlet with a NEMA 5-15P plug

It plugs into a standard 120 V, 15 A household outlet with a NEMA 5-15P plug. The product page doesn't say it needs a dedicated circuit. Shipping is advertised as free. The sauna arrives by freight with lift-gate service at a scheduled delivery appointment, and someone 18 or older must sign for it. Clearlight says two people usually assemble it in about 1 to 1.5 hours with a screwdriver and the included Allen wrench. Its FAQ says 1 to 3 hours. Clearlight offers installation service in some areas but doesn't state a price.

WarrantyClearlight says its residential Limited Lifetime Warranty covers the entire sauna…

Clearlight says its residential Limited Lifetime Warranty covers the entire sauna for as long as you own it. That means the heaters, control panels and electrical components, wood cabin, audio and chromotherapy lighting. Parts and shipping are covered for life, but labor isn't. The warranty page says labor is covered for an initial period without giving its length. The Sanctuary owner's manual, which lists Sanctuary 1, sets labor at 7 years for indoor home use in the US and Canada. The manual counts coverage from the purchase date. It also says the warranty can't be transferred without written consent from Sauna Works, which issues it. Commercial use falls under a 5-year warranty. The warranty page says registration is automatic when the sauna ships. The manual instead asks you to register within 30 days of purchase.

ReturnsClearlight calls it a "30 Day Risk-Free Return Policy," but a return isn't free

Clearlight calls it a "30 Day Risk-Free Return Policy," but a return isn't free. You have 30 business days from receipt and need a return authorization (RMA). The sauna must be in new or like-new condition, with undamaged original packaging and all manuals. Clearlight deducts a 25% restocking charge and the original shipping charges. If the sauna shipped under a free or discounted shipping promotion, that means the actual freight cost. You also pay return shipping. Custom, private-label and non-standard models are non-refundable. Orders canceled before shipment are fully refunded. Concealed damage must be reported within 5 business days of delivery.

More about this assessment

Sanctuary 1 is a one-person full-spectrum infrared cabin in mahogany or basswood. Clearlight says it plugs into a standard 120 V, 15 A outlet, but its rated 14.6 A draw uses nearly all of that outlet's rating. There's no list price, so you have to request a quote. The residential limited lifetime warranty covers parts and shipping for as long as you own the sauna. Labor is covered for 7 years, according to the owner's manual. Returns carry a 25% restocking charge plus shipping costs.

Energy component: Unknown

Purchase + installation + years × (annual consumables + annual other) + watts/1000 × hours/day × 365 × years × $/kWh. Annualized allowances, not an exact replacement schedule. Excludes taxes, shipping, finance and resale unless entered.

Replacement parts & cost assumptions

No scheduled consumable is listed. That does not mean zero maintenance or repair costs.

Purchase is unknown because the product page listed no price on Oct 13, 2026. The sale banner and financing offers don't state a list price, so they aren't used to estimate one.
The pages checked show no recurring proprietary part. The $0 for annual consumables doesn't mean zero electricity, cleaning, shipping, installation or repair costs. Smartphone control has no stated fee, so other yearly costs are left unknown rather than set to zero.
Installation is unknown. You can assemble the cabin yourself and plug it into a standard outlet. Clearlight's installation service, offered in some areas, has no stated price, and any electrical work would cost extra. Shipping is advertised as free.
The 1,740 W figure is the product page's rating, not a measured average. Clearlight's FAQ estimates about 20 to 25 cents per session for its saunas in general. It doesn't give the electricity rate or name this model. With no daily use stated, energy isn't estimated.

Evidence & sources.

Are saunas good for you? Our evidence review grades the research as Moderate. That grade is about the claim, not about this product.

Manufacturer claimDimensions, heater layout, electrical rating, materials and features are Clearlight's published specifications.¹ Not independently tested for this review.
Manufacturer claimClearlight describes its saunas as General Wellness products not evaluated by the FDA. It says they aren't intended to treat, cure or prevent diseases or medical conditions.¹ This is Clearlight's own regulatory statement, not an FDA clearance. The product page also carries benefit marketing and study citations, which aren't assessed here.
Manufacturer claimClearlight's FAQ lists ETL and CE certification among its quality standards. It also says True Wave heaters measure less than 1 mG when tested directly on the heater. Intertek and CE logos appear in the site footer, but the product page itself doesn't mention ETL.^{1, 5} These are Clearlight's statements only. The pages checked show no certificate number, listing, test standard, lab or report. The FAQ doesn't say which models are covered, and the claim wasn't confirmed in a certifier directory.
