Quick Answer: Used infrared saunas on Facebook Marketplace and Craigslist typically sell for 50-70% off retail — a $3,500 two-person cabin often resells for $900-$1,400 after a few years of light use. That’s a real discount if the cabin checks out, but factor in likely repair costs first: a $1,200 used unit needing electrical work, replacement panels, and transport can land close to $2,050 in real cost, which narrows the gap with a new entry-level cabin fast. Inspect the exterior panels, door seal, control panel, and heating elements in person before buying, and always test-run a full heat cycle first.
A “used sauna for sale” listing looks like free money until you’re the one paying to fix a cracked panel or rewire a corroded outlet. Here’s what actually determines whether a used cabin is a deal or a liability.
Why used saunas are so much cheaper than new
The resale math is steep. A 2-person infrared cabin that retailed around $3,500 commonly turns up on Marketplace for $900-$1,400 within a few years of light residential use, per marketplace-tracking guides for used saunas — sellers moving, downsizing, or replacing a unit for a bigger model dump inventory well below what it’s worth in working condition. Single-person cabins start even lower, often listed from $600, and full-size 3-4 person units from name brands like Sunlighten or JNH Lifestyles regularly show up in the $850-$2,000 range depending on age and condition.
That steep discount is real, but it assumes the cabin needs nothing. The moment it needs a part or an electrician, the math changes.
What to check before you hand over cash
Work through this in person, before you pay:
- Exterior panels. Press firmly on the wood panels looking for warping, soft spots, or water-stain discoloration — signs of moisture damage that won’t show up in photos.
- Door seal. Press the door seal closed and check for gaps; a failed seal lets heat escape and makes the cabin run inefficiently for the rest of its life.
- Control panel. Power it on and test every button — sticking, flickering, or unresponsive controls point to failing electronics that are expensive to source for a discontinued model.
- Heater and panels. Listen for buzzing or ask to run a full heat cycle. Infrared emitter panels are rated for roughly 30,000 hours of use, so age alone rarely kills them — physical damage or a loose wire connection is the more common failure.
- Model and age. Get the exact brand and model number and look up when it was discontinued. Replacement infrared emitter panels run $200-$600 each, and parts for an older or discontinued model can be hard to find at any price.
| Scenario | Sticker price | Hidden costs | Real total cost |
|---|---|---|---|
| Used cabin, needs nothing | $900-$1,400 | $0 | $900-$1,400 |
| Used cabin, needs electrical + parts + transport | ~$1,200 | $400 electrical + $250 parts + $200 transport | ~$2,050 |
| New entry-level cabin (e.g. Smartmak, plug-in) | ~$180-$200 | $0 — new, warrantied | ~$180-$200 |
| New 2-person cabin (e.g. Dynamic Andora, plug-in) | ~$1,900 | $0 — new, warrantied | ~$1,900 |
The real math: used isn’t always the cheaper choice
Run the numbers before you commit. A used cabin listed at $1,200 that needs $400 in electrical repairs, $250 in replacement parts, and $200 to transport home has an actual cost of about $2,050 — within a few hundred dollars of a brand-new Dynamic Andora 2-person cabin at roughly $1,900, which arrives with a full warranty, free shipping, and zero repair risk. The used cabin only wins decisively if it passes every check above with no repairs needed.

Where to buy used safely
Facebook Marketplace and Craigslist carry the highest volume of used residential sauna listings and, critically, let you inspect and test the cabin in person before paying — insist on running a real heat cycle, not just a visual look. Local pickup also avoids the freight cost of shipping a large cabinet, which can otherwise erase a chunk of the discount on its own. Be more cautious with eBay or shipped listings you can’t test first, and walk away from any seller who won’t confirm the exact brand and model or won’t let you plug it in.
When new beats used
If a used listing needs any real repair work, or you can’t verify the model and test it in person, a new entry-level cabin is usually the safer bet. The Smartmak far-infrared portable sauna starts under $200 — often cheaper than a “deal” used cabin once you add transport and repairs — and our best infrared sauna guide ranks the full lineup of new cabins by price and features if you want the Andora’s warranty without the used-market gamble.
Bottom line
A used sauna can be a genuine 50-70% discount, but only if it passes a hands-on check of the panels, door seal, control panel, and heater, and needs zero repair work. Run the real math before you buy: add likely electrical, parts, and transport costs to the sticker price, and compare that total against a new entry-level cabin with a warranty. When in doubt, or when a seller won’t let you test-run the heater first, buying new removes the guesswork entirely.
