Sunlighten Amplify II Price: What It Costs New and Used
Sunlighten Amplify II price: roughly $7,000 to $8,000 new and $5,500 to $6,500 used. Specs, line comparison, what to inspect, and how to move one.
The Sunlighten Amplify II price is the one number Sunlighten will not put on its website. You fill out a form, a consultant calls you, and eventually you get a quote. Based on what these units list for secondhand and the retail figures sellers cite on their own listings, a new 2-person Amplify II lands somewhere between $7,000 and $8,000 once you add the wood and options most buyers pick. A clean used one trades for $5,500 to $6,500.
I help people buy and sell big, heavy things for a living, and saunas are among the most common items we move. I have watched a lot of Sunlighten cabins get taken apart in one garage and reassembled in another. So this is the practical version of the question: what the Amplify II actually costs new, what it goes for used, how it compares to the Signature and mPulse lines, and what to check before you buy somebody else's.
What Does a Sunlighten Amplify II Cost?
A new Sunlighten Amplify II costs roughly $7,000 to $8,000, and a used one costs $5,500 to $6,500 in good condition. That is a narrower gap than you get on most big-ticket wellness gear, and the reason is simple: these cabins barely wear out. There is no pump, no water, no filter, and no moving part except a door hinge.
| How you buy it | What you pay | What you get |
|---|---|---|
| New, direct from Sunlighten | Roughly $7,000 to $8,000 quoted | Full warranty, delivery to the curb, white-glove setup usually costs extra |
| Used, like new (1 to 2 years) | $5,750 to $6,500 | Same cabin, no factory warranty, you handle the move |
| Used, good (3 to 5 years) | $4,500 to $6,000 | Expect minor wood marking, heaters typically still fine |
| Used, older or partial | $2,200 to $4,000 | Older control panel, possible missing hardware, verify heaters work |
Those used figures come from what Sunlighten cabins actually list at on our own platform, where prices have ranged from around $2,200 for an older 2-person Amplify up to $8,250 for a larger mPulse. A brand-new Amplify II listed with a $7,500 retail reference. Use those as your anchors when a seller quotes you a number.
Why Sunlighten Does Not List the Price
Sunlighten sells through consultants, not a shopping cart. That is a deliberate choice, and it means the Sunlighten Amplify II price you are quoted depends on when you call, what promotion is running, and which options you take. Four things move the number.
- Wood. Basswood is the standard. Eucalyptus is the upgrade, and it typically adds several hundred dollars.
- Size. The Amplify II seats two. The Amplify III seats three or four and costs meaningfully more, though used Amplify III units sometimes sell for less than a used II because fewer buyers have room for one.
- Promotions and bundles. Sunlighten runs seasonal offers that fold in accessories, chromotherapy, or an audio upgrade instead of cutting the sticker.
- Delivery and setup. Curbside delivery is one price. Getting it into a basement and assembled is another, and on a modular cabin that charge is not trivial.
None of that applies when you buy used. On the secondhand market the price is the price, and the options that cost extra when new (eucalyptus wood, chromotherapy, the upgraded panel) come along for free because most sellers do not know to charge for them. Ask what options the unit has. It is free money if it has the good ones.
Amplify vs Signature vs mPulse: What You Get for the Money
The Amplify is Sunlighten's full-spectrum cabin without the smart-control premium of the mPulse. That is the whole positioning in one sentence. The Signature line is far infrared only and costs the least. The mPulse adds programmable wavelength control and app-driven sessions and costs the most.
| Signature | Amplify | mPulse | |
|---|---|---|---|
| Infrared type | Far infrared | Full spectrum | Full spectrum, programmable |
| Red light / LED | Optional | Included | Included |
| Control | Simple panel | Touchscreen panel | Touchscreen, app, custom programs |
| Typical used price, 2-person | $2,500 to $4,000 | $5,500 to $6,500 | $3,400 to $6,000 |
| Best for | Sweating on a budget | Most buyers | People who want to tune wavelengths |
My read after watching these move: the Amplify II is the model to buy used. The Signature is cheaper but you give up near infrared and the LED panel, which is most of why people choose Sunlighten over a $2,000 cabin from a big-box site. The mPulse is genuinely more capable, but the extra features are software, and software is exactly what ages worst on a ten-year appliance. Buy the cabin, not the app. If you want the full comparison, we broke down how the mPulse stacks up against Clearlight and GHS separately.
What to Inspect on a Used Sunlighten Amplify II
Run every heater for twenty minutes before you agree to anything. That is the whole inspection in one line, and almost nobody does it. Infrared heater panels fail individually, not all at once, so a cabin can heat up and still have a dead panel behind the bench that you will not notice until the first cold week.
The order I would go in: power the unit on and let it run to temperature, then put your hand near each heater panel in turn (front, back, side walls, under the bench, calf panel) and confirm every one is warm. Check the LED panel actually lights. Then work the control panel through its full menu, set a temperature, set a timer, and confirm it holds. A control panel that boots but will not hold a setting is the most expensive thing on this cabin to fix.
After the electronics, look at the wood. Basswood and eucalyptus both mark easily, and sweat stains on the bench are cosmetic and normal. What is not normal is a panel that has bowed or cupped, or a seam where two wall panels no longer meet flush. That means the cabin was stored somewhere damp or was assembled and disassembled carelessly, and warped panels do not go back together tight. Finally, pull the bench and look at the wiring runs between panels: the connectors should be seated and the harness should be free of tape repairs and rodent damage. Saunas that sat in garages sometimes have both.
Electrical, Space, and Whether It Works in a Garage
Most 2-person Sunlighten cabins run on a dedicated 120V 20-amp circuit, which is the single most important thing to confirm before you buy. Read the label on the unit itself rather than trusting a listing, because larger models step up to a 240V circuit and that is an electrician visit, not an extension cord. Never run one on an extension cord or a shared circuit with anything else on it.
For footprint, plan on a little under four feet wide by about three and a half feet deep, and close to seven feet of ceiling height once you account for the roof cap. Measure your doorways too, but measure them for the panels, not the assembled cabin, because you are moving it in pieces.
A garage works if the garage is insulated and dry. An uninsulated garage in a cold climate is a bad home for an infrared sauna, and not for the reason people assume. The unit will still heat. The problem is the humidity swing, which is what warps panels and corrodes connectors over a few seasons. A finished basement is the better answer nine times out of ten, and it is also where most of the used ones we pick up have been living.
Moving One Without Wrecking It
Sunlighten cabins are modular and come apart on purpose. The walls, roof, floor, and bench are separate panels that clip together, and two people who know what they are doing can break one down in well under an hour. The glass door is the fragile part and it should come off first and travel flat and padded.
The two things that go wrong: people lose the small hardware, and people scrape a panel face while carrying it. Bag every clip and screw and tape the bag to the inside of a wall panel. Blanket-wrap each panel individually rather than stacking them bare. If a seller tells you they will "just have a couple of guys grab it," expect at least one scratched panel.
Warranty is the other thing to settle before money changes hands. Sunlighten's coverage is written for the original purchaser and does not follow the cabin to a second owner in a private sale. Assume you are buying it uncovered. If that matters to you, call Sunlighten with the serial number before you buy and ask directly, since policies change and it costs you one phone call to know.
This is the part our process was built for. Drivers disassemble the cabin at the seller's house, run it through a 30 to 50 point inspection, photograph and video the heaters running before it leaves, and reassemble it at yours. You get up to 60 minutes to test it at home before you pay anything, buyers and sellers never meet, and it comes with a 60-day warranty that has nothing to do with Sunlighten's. Browse used saunas with delivery handled if you would rather skip the panel-carrying.
Frequently Asked Questions
How much does a Sunlighten Amplify II cost?
Expect a quote in the $7,000 to $8,000 range for a new 2-person Amplify II, depending on wood choice, promotion, and delivery. Used units in good condition sell for $5,500 to $6,500, and older or incomplete ones drop toward $2,200. Sunlighten does not publish list prices, so the only way to get an exact new number is to request a quote.
Is a used Sunlighten sauna worth buying?
Usually yes. Infrared cabins have no water, no pump, and no filter, so the failure modes are limited to heater panels, the control board, and warped wood. All three are checkable in twenty minutes. You save a couple thousand dollars for doing that inspection, which is a better hourly rate than most things you can do with your afternoon. Our guide on used sauna vs new runs the full math.
What is the difference between Amplify and Amplify II?
Amplify is the product line and the Roman numeral is the capacity. Amplify II is the 2-person cabin and Amplify III seats three to four. Confusingly, used Amplify III units sometimes sell for less than a used Amplify II, because far fewer buyers have a room that fits one.
Does a Sunlighten Amplify II need special wiring?
Most 2-person Sunlighten cabins run on a dedicated 120V 20-amp circuit, which many finished basements already have or can get cheaply. Larger cabins may need 240V. Confirm the requirement from the label on the actual unit before you buy, and budget for an electrician if you do not have a free dedicated circuit where the sauna is going.
Can you move a Sunlighten sauna yourself?
Yes, if you have a second person and some patience. The cabin is modular and clips apart into wall, roof, floor, and bench panels. Take the glass door off first, bag and label the hardware, and blanket each panel separately. The mistakes are almost always dropped hardware and scraped faces, not structural damage.
Is the Sunlighten warranty transferable?
No, not in a private sale. Sunlighten's warranty is written for the original purchaser. Price a used cabin as if it has no factory coverage at all, and if you want certainty, call Sunlighten with the serial number before you commit.
The short version: the Sunlighten Amplify II price is roughly $7,000 to $8,000 new and $5,500 to $6,500 used in good shape, and the used one is the better buy for almost everybody. Run every heater, work the control panel, check the wood for warping, confirm the circuit, and settle the warranty question up front. Do those five things and you have removed nearly all the risk of buying secondhand.
And if you are on the other side of this and have a cabin taking up a basement you would rather use for something else, here is how to sell a sauna without losing money on the resale, or list it with us and let a driver handle the disassembly. If you are still deciding between technologies entirely, start with infrared versus traditional before you shop a specific model.
