Sunlighten sauna prices: what's listed, what isn't, and what comparable saunas cost

What Sunlighten publishes

I checked each model page and the brand's online store. The store sells the Amplify, Signature and Solo lines; the mPulse cabins appear there only as accessory packages, so their price comes with a quote.

The Sunlighten Amplify RED II was listed but sold out on the day. The Amplify II and III also come in Basswood, for $200 less than the Eucalyptus prices above. I don't repeat prices from blogs or forum posts here. They're usually someone's quote at some date, with or without delivery and options, and they aren't Sunlighten's published price. If you've been quoted for an mPulse, the questions below help you compare.

How to get a Sunlighten price

For the mPulse, the "Get pricing" form on each model page is the route, and a sales representative follows up. For a listed model, the same questions are worth asking before you order. Get these in writing:

• the total with delivery, and whether delivery is to the curb or into the room;
• the wood: most models come in Basswood or Eucalyptus, and the price differs;
• the manufacture date. The warranty applies only if the sauna is bought and activated within one year of it;
• the return terms that apply to your order, including whether "unopened" is the condition;
• the delivery window.

Costs you can know in advance

Returns. Sunlighten's return policy (checked October 16, 2026) takes back mPulse, Amplify, Signature and Solo within 30 days of delivery only in the original unopened packaging. Returns, exchanges and cancellations "may be subject to" a 3% administrative fee, storage fees, a $499 restocking fee per cabin ($299 for a Solo System) and return shipping. A Solo Dome or SoloPad bought on its own counts as an accessory: no unopened condition, with restocking fees of $299 a dome and $99 a pad.

Wiring. No Sunlighten cabin runs off a standard 15 A outlet. The one- and two-seaters need a dedicated 120 V 20 A circuit; the three- and four-seaters and the Amplify RED II need 240 V on a 20 A circuit. Model by model: mPulse Aspire 120 V 20 A, mPulse Believe 120 V 20 A, mPulse Conquer 240 V, Amplify II 120 V 20 A, Amplify III 240 V, Amplify RED II 240 V, Signature I 120 V 20 A, Signature II 120 V 20 A, Signature IV 240 V. If you don't have that circuit, get an electrician's quote before you sign; a licensed electrician should do the work.

Delivery. The store lists free shipping for the Signature I, the Amplify II and the Solo System. For the mPulse, delivery terms come with the quote.

How expensive is an infrared sauna to run?

Use the wattage on the spec sheet. Watts ÷ 1,000 × hours of use gives kilowatt-hours, and your electric bill tells you what a kilowatt-hour costs where you live. The rated wattage is the most the sauna can draw, so the real figure is at or below it.

• Sunlighten Signature I: 1,350 W, so at most 1.35 kWh per hour;
• Sunlighten mPulse Believe: 2,400 W, at most 2.4 kWh per hour;
• Sunlighten mPulse Conquer: 3,600 W, at most 3.6 kWh per hour.

Count the preheat too: Sunlighten recommends 45–60 minutes for the Signature. A full comparison of running and buying costs across sauna types is on how much a sauna costs.

Comparable saunas with a listed price

Within each class the order is by price. Heavenly Heat gives 10 years on its indoor saunas, against Sunlighten's 7. For red light in a cabin, Sun Home publishes prices for models that compete with the mPulse, but its warranty terms conflict between pages, which its review explains. Brand reviews: Heavenly Heat, Sun Home, Clearlight.

Is it worth paying more for Sunlighten?

For the Amplify and Signature you can now compare listed prices directly. The Sunlighten Signature II at $5,499 costs less than the Heavenly Heat 2-Person Far Infrared Sauna at $7,400, while the JNH Lifestyles Tosi 2-Person Cedar is $5,199 with full-spectrum heat. Sunlighten gives detailed spec sheets, a 7-year warranty, and, in the mPulse line, separate far, mid and near infrared plus red LED panels that no brand with listed prices matches one for one. Against that, its returns end when you open the box, and Heavenly Heat's warranty runs longer. Whether infrared heat does what you want it to is a separate question: what studies of infrared saunas show.
