Installing a wood stove in a cabin costs between $3,500 and $7,000 all in, once you count the stove, the chimney pipe, the hearth pad, the wall protection, the permit, and the inspection, and the chimney is usually half of that. I've put stoves in five cabins now. The first one I did wrong in three separate ways and got a very patient lecture from a county inspector named Dale. The last one passed first time. This is what I know, in the order you'll need it: clearances, the chimney, the hearth, the permit, what it costs, and the mistakes, so you can skip mine.
One thing up front. A wood stove is the best heat a cabin can have and it's also the thing most likely to burn one down. Every number below is there because someone's cabin burned. Don't round them.
Wood stove vs fireplace: why a cabin wants a stove
A fireplace looks better in a photo and heats the room worse. Most of the heat goes up the flue, and when the fire dies the open chimney pulls warm air out of the cabin all night. A modern wood stove, the EPA-certified kind, burns at 70 to 80 percent efficiency, heats the whole cabin from one spot, holds a fire overnight on a good load, and burns a third of the wood a fireplace does for the same heat. In a small cabin, one stove is the heating system. I've written about restoring an old stove and building the hearth around it; this post is about putting one in from scratch.
If you have a fireplace already and want the look, a stove insert goes into the existing opening and gets most of the efficiency back. Everything below about chimney and clearance still applies.
Clearances: the numbers that matter
Every stove ships with a clearance sheet, and that sheet is the law for that stove. Read it before you pick the spot, not after. But the shape of it is the same for nearly all of them:
Unprotected combustible wall, meaning a log or wood-paneled wall with nothing on it: 36 inches from the stove body, on every side. That's three feet. In a small cabin, three feet from two walls in a corner eats a lot of floor, which is why people cheat, and cheating is how log walls catch fire slowly over years as the wood dries out and its ignition point drops.
Protected wall, meaning a heat shield: the clearance drops, often to 12 inches or so, if the shield is built right. Built right means a non-combustible panel, cement board or sheet metal, mounted on one-inch spacers so air flows behind it, open at the top and bottom. A tile-on-drywall wall with no air gap is not a heat shield, no matter what the tile store said. Dale explained this to me at cabin one while pointing at a scorch mark I hadn't noticed.
Stove pipe, the single-wall pipe from the stove to the ceiling: 18 inches from anything combustible. Double-wall pipe cuts that to six.
Floor: the stove sits on a hearth pad, and the pad has to extend at least 16 inches in front of the loading door and 8 inches on the other sides in most codes, sometimes more. The pad's job is embers, not heat. A dropped coal on a wood floor is the second-most-common way these things go wrong.
The clearance sheet that came with the stove beats anything on the internet, including this. Tape it to the wall while you plan. Then tape it inside the cabinet under the sink, because the inspector will ask for it.
The chimney: where the money goes
You'll spend more on the chimney than the stove, and that's correct. The stove is a steel box. The chimney is the thing that keeps 500-degree exhaust away from your rafters for thirty years.
Two kinds. Single-wall black stove pipe runs from the stove up to the ceiling, inside the room, and that's all it's for. At the ceiling it changes, through a ceiling support box, to insulated Class A chimney pipe, the double-wall stainless kind, which runs through the attic or loft and out the roof, at least three feet above the roof where it exits and two feet higher than anything within ten feet. That's the 3-2-10 rule and it's what stops downdrafts and smoke in the cabin.
Straight up is best. Every bend costs draft. My cabin one stove had two 45s to dodge a beam and it never drew right until I moved the stove eighteen inches and went straight. If you can put the stove where the pipe goes straight through the roof, do that, and pick the stove's spot around the chimney rather than the other way.
Cost: a 15-foot run of Class A pipe with the support box, roof flashing, storm collar, and cap runs $1,400 to $2,200 in materials. Single-wall pipe and the connectors, another $150. If your roof is metal, which most cabins here are, the flashing has to be a metal-roof flashing, not the shingle kind, and it's the one part I'd never let a first-timer do. A leak there rots the roof deck under the metal where you can't see it.
Building the hearth
A hearth pad can be bought, a factory-made board that meets code, for $250 to $500, and for a first install that's what I'd do. Or you can build one, which I've done four times: a frame of 2x4 on the floor, cement board on top, tile or stone on that, and a trim edge. Cost around $300 in materials and it looks like it belongs to the cabin. The catch is the R-value: some stoves need a pad that insulates, not just one that's non-combustible, and if yours does, a homemade tile pad on cement board doesn't cut it without an insulating layer underneath. Again, the stove's sheet says.
I like a raised hearth, six or eight inches up, because it makes the stove easier to load without kneeling and gives a place to sit. It also gets the stove up where the light from the fire fills the room, which sounds like a decorating point and is actually the reason a cabin with a stove feels the way it does at night. I wrote about that in the layering light post. The stove is a lamp that happens to heat.
The permit and the inspection
Get one. In my county it's a mechanical permit, about $75, and the inspection is a guy with a tape measure checking the clearances, the pipe, and the pad against the manufacturer's sheet. Dale has been to four of my cabins. He's failed me once, on cabin one, for the heat shield with no air gap and for a stove pipe that was 14 inches from a beam instead of 18. Both fixes took an afternoon. If he hadn't failed me, I'd have been sleeping under a slow fire.
The other reason for the permit: insurance. A wood stove that wasn't permitted and inspected is a stove your insurer can use to deny a fire claim, and they will. Ask me how I know a guy who found that out.
What the whole thing cost, cabin by cabin
Cabin one, 2016, done mostly wrong then fixed: stove $1,100 used, chimney $1,600, hearth $280 built, shield $140, permit $75, plus the fixes, about $3,400 total and two weekends. Cabin four, 2022, done right the first time: stove $2,300 new, chimney $2,100 including metal-roof flashing that I paid a roofer $350 to set, factory hearth pad $420, shield $180, permit $75. About $5,400 and one long weekend plus the roofer's morning. The cabin I live in, 2024: a bigger stove, $2,900, everything else similar, about $6,100.
Buying used is fine for the stove if it's EPA-certified, which means built after about 1990 and has a tag saying so. Older stoves are cheap and burn dirty and some counties won't permit them. Never buy used chimney pipe. You can't see the inside.
The mistakes, in order of how bad they were
The heat shield with no air gap. Tile glued to the wall behind the stove, which does nothing, and the log behind it was charring. Fix: tear it off, cement board on one-inch ceramic spacers, tile on that, open top and bottom.
The two 45-degree bends. Smoke in the cabin every cold start for a year. Fix: move the stove, straight pipe.
The chimney cap I skipped to save $60. Rain down the pipe, a cup of creosote sludge in the stove every storm, and a bird. Fix: the $60 cap.
Not enough chimney above the roof. I did three feet and the roof peak was eight feet away and higher, so on a north wind the stove puffed back into the room. Fix: two more sections, $180, and the 3-2-10 rule tattooed on my brain.
Wet wood. Not an install mistake but it undoes everything. Wood needs a year split and stacked to get under 20 percent moisture, and a $25 meter tells you. Green wood makes creosote, and creosote is what burns in a chimney fire. Sweep the chimney every fall, or every cord if you burn a lot; a brush and rods are $60 and it's a twenty-minute job from the roof.
Sizing the stove: bigger isn't warmer
Stoves are rated by the square footage they'll heat, and the temptation is to buy one rated for more than the cabin. Don't. An oversized stove in a small cabin runs choked down all the time, and a choked stove burns cool and dirty, coats the chimney in creosote, and makes the cabin either too hot or, when you let it die back, too cold. The right stove runs with the air open most of the time, which is how it was designed to burn clean.
Rough numbers that have worked for me: a cabin under 800 square feet with normal ceilings, a small stove rated around 1,000 to 1,200 square feet, because the ratings assume a well-insulated house and an old cabin isn't one. A 900 to 1,400 square foot cabin, a medium stove, 1,500 to 1,800 rated. An A-frame with a tall peak, go one size up from the floor area, because the heat lives in the peak and you're heating the volume, not the floor. Cabin one had a stove rated for 2,000 square feet in a 700-square-foot A-frame. I ran it with the air nearly shut for two winters and swept a coffee can of creosote out of the chimney every month. The medium stove I replaced it with heats the same space better on less wood, and the chimney's clean.
The other sizing question is the firebox: can it take a 16-inch log? Most firewood around here comes cut to 16 and a stove that only takes 12 means you're re-cutting every piece. Check the firebox depth before you check anything else on the spec sheet.
Where to put it in a small cabin
Center of the main room if the chimney can go straight up from there, which in an A-frame it usually can. Against an interior wall, not an exterior one, so the heat stays in the building and the chimney stays warm and draws. Not in a corner unless you've got the clearances, because a corner install with a log wall on two sides needs two shields and still eats the corner. And not next to the stairs to the loft, because that's where the heat goes anyway and the loft will be 85 degrees while the floor is 60. I've written about reworking a loft, and where the stove sits was half of it.
Cabin four's stove sits on a raised stone hearth in the middle of the back wall, straight pipe, twelve feet from the loft stairs, with a ceiling fan on reverse pushing the warm air back down. It heats 900 square feet to 68 on a 20-degree night on one load, and it holds coals until morning. That's the install I'd copy.
A stove lights the room from knee height. The rest of the cabin still needs light at eye level: wall sconces on the log walls, warm bulbs, dimmed low so they don't fight the fire. The fire is the main light. The sconces are the fill.
