A barrel sauna sells for about $4,250 and a portable steam tent for about $80. Both show up under 'used sauna'. Here is what each type really costs.

A used barrel sauna sells for about $4,250. A portable steam tent sells for about $80. Both come up when you search "used sauna", and any average that includes both is a number that describes nothing. Type decides price in this category more than brand, age or size, and almost nobody separates them.
I sell this equipment for a living, and the sauna market is the most confusing one I deal with. Below is what each type actually goes for, so you can tell whether the listing you are looking at is a bargain, a rip-off, or a completely different product to the one you had in mind.
| Type | Typical price | Most sell between |
|---|---|---|
| Barrel sauna | $4,250 | $1,808 to $5,450 |
| Cedar sauna | $3,500 | $1,500 to $4,700 |
| Outdoor sauna | $3,300 | $925 to $3,925 |
| Four-person cabin | $3,000 | $2,025 to $4,900 |
| Two-person cabin | $1,200 | $250 to $2,000 |
| Infrared cabin | $1,100 | $250 to $1,800 |
| Portable tent or blanket | $80 | $55 to $105 |
That is a fifty-fold spread inside one search term. It is why "average used sauna price" is a useless figure and why sellers so often price theirs wrong in both directions.
A cabin is a wooden room with a heater, either infrared panels or a traditional stove. This is what most people picture. Used, a two-person infrared cabin runs around $1,100 and a four-person around $3,000.
A barrel or outdoor cabin is a standalone structure for the garden, usually cedar, usually traditional rather than infrared. These hold value best of anything in the category at around $4,250, because they are expensive new, built to sit outside, and genuinely hard to find secondhand.
A portable tent or blanket is a zip-up fabric enclosure with a small steam generator, or a padded wrap you lie inside. At around $80 used it is a different product at a different price point, and it is the thing dragging every "used sauna" average down.
If you are shopping, decide which of the three you actually want before you look at a single price, because otherwise the listings will look wildly inconsistent for no apparent reason.
Infrared cabins heat your body directly with panels, run cooler, plug into a standard outlet in most cases, and are far more common on the secondhand market. That availability is why they sell around $1,100 while comparable traditional cabins hold higher prices.
Traditional saunas heat the air with a stove and rocks, run much hotter, and give the steam experience people associate with a Finnish sauna. They tend to need more power and more ventilation, which makes installation the real cost rather than the unit.
Neither is better. They are different experiences, and the one you prefer is worth establishing before you spend $3,000 on the other.
Power it on and let it reach temperature. Infrared panels fail individually and a cabin with two dead panels still lights up and still gets warm, just not evenly. On a traditional unit, look for cracked stones and corroded elements.
Check the door seal and the glass. Warped doors are common on cabins that lived in a garage and they are difficult to fix. Look at the bench supports and the floor for water damage, particularly on anything that has been outside.
Ask how it will come apart. A barrel sauna is not going through a standard doorway assembled, and the honest answer to "how do I get this home" changes what you should pay.
Most people underprice a sauna badly, because they search "used sauna", see portable tents at $80, and assume theirs is worth a few hundred dollars. If you own a cedar barrel unit you are closer to $4,250, and if you have an outdoor cabin you are around $3,300.
Find your type in the table above, adjust for capacity and wood, and be honest about heater age. Then list it. Commonplace handles the part that stops most private sales dead: we send a driver, take it apart if it needs taking apart, and pay you at pickup. Nobody has to come and look at it in your garden first.
It depends entirely on type. A portable tent is around $80, an infrared cabin around $1,100, a four-person cabin around $3,000 and a cedar barrel unit around $4,250.
Outdoor and barrel units hold value well because they are costly new and scarce used. Portable units hold almost none. Infrared cabins sit in between and are the most heavily discounted type secondhand, which makes them the best value if a cabin is what you want.
Often yes. The panels and frame are simple and long-lived, and the discount against new is steep. Test every panel individually before you commit, because a partly dead cabin still warms up.
A barrel is a round outdoor structure, nearly always cedar and traditional. A cabin is a square indoor unit, usually infrared. The barrel is roughly four times the price used.
Cabins come apart into panels and move easily. Barrel saunas usually need to be partly disassembled and moved on a trailer. Always ask before agreeing a price, because the move is a real cost.
