Homemade smokers make awesome BBQ at an affordable price.

But before you get started, a few safety tips.

Do NOT use:

  • lead
  • cadmium-plated metal (including old fridge shelving)

These are heavy metals, will not come out of the body, and are extremely dangerous.

Also, beware of hexavalent chromium! This harmful carcinogen is a byproduct of welding galvanized steel. Impurities like lead can also surface from welding galvanized materials.

On Galvanized Materials…
Galvanized surfaces are not food-safe. They are coated with zinc which will be absorbed into the food, so do not let food come in to contact with them.

That said, if the galvanized material has not been welded and does not come into contact with food, it’s probably OK to use in your smoker. Understand that a little zinc may be deposited on the food.

But a little zinc isn’t bad for the body…many people take zinc regularly for their immune system. However, a lot can be harmful and give you flu-like symptoms.

Keep in mind:

  • Zinc melts at 420 C / 790 F
  • Zinc boils at 900 C / 1700 F

Smokers almost never operate above 200 C / 400 F, so the risk of adding significant zinc to food is low. However, if you are still concerned, start a fire outside in that galvanized trash can. That should get the temperature high enough to melt off the zinc. Just don’t inhale the fumes!

Just what is a smoker, anyway?

It’s basically a box that smoke passes through. Learn more about the basics at the smoker guide section.


Metal Barrel

Most homemade smokers start with a 55 gallon steel drum.

A few tips:
Pick a barrel that is new or food-grade.

Do not use an old gas / oil barrel!
Your food will never taste right.

If there is any sort of lining or residue inside the barrel, burn it off. That’s right! Let out that inner pyro.

Why not!? After all, they keep your cold things cold and your hot things hot!

A cooler makes for a well-insulated homemade smoker. Just take a few precautions not to let the heating element touch the plastic.

Oh, and yes, your cooler will smell like smoked BBQ forever. Benefit or disadvantage? You decide.

Bricks / Cinder Blocks

It’s not just a smoker – it’s a piece of your backyard.

Brick pits are a unique part of our history and heritage – dating back to the original commercial BBQ pit. Something about them takes you “back to the simpler times.”

A quality brick pit has also long been considered one of the best ways to smoke BBQ. They’re well-insulated and last a lifetime when built correctly.

Old Refrigerator

Believe it or not, an old refrigerator can make a great homemade smoker with little or no modification.

Unfortunately, new fridges make poor smokers. They are mostly plastic, which does not hold up well under heat. They do, however, make great fridges.


Before we begin, a few words of safety:

Old refrigerators usually contain bad stuff. Really toxic, nasty, bad stuff.


Before using a fridge to smoke food, please do everyone a favor - remove all the bad stuff. This includes:

  • Plastic
  • Electronics, wires, etc.
  • ANY Thermometers / thermostats
  • Original Shelving


That’s right, throw away the original shelving.

Don't keep the metal shelving to save money on materials. Sometimes, the old shelving has been plated with cadmium – a highly toxic heavy metal. Aluminum racks will also corrode with salty BBQ.

Don’t let old racks taint your food – toss ‘em!

Instead, try using stainless steel racks from an old kitchen stove.

Cardboard Box

You’ve got to be kidding, right?

Nope! A sturdy cardboard box makes a good smoker.

Great for camping trips - when you’re done, burn the box!

Just know that your smoker is flammable. If it feels like it’s getting hot, spray the edges down with water. Or, line the inside with foil to deflect the heat. As long as your heat source does not touch the cardboard, you’re probably OK.

Also, use a cardboard smoker away from trees or houses, and keep a hose or fire extinguisher handy.

That’s right, wood!

Plywood, planks, or logs – you can build a great smoker out of wood. Here, we show you how to build the basic wooden smoker box. For a bigger (possibly more useful / permanent) wooden smoker, check out the smokehouse construction section. <link>

Also, know that your smoker is flammable. Don’t build it by your house or under trees, and keep a hose or fire extinguisher nearby.

Line the insides with thin sheets of metal. This:

  • Reflects the heat
  • Shortens smoking times
  • Keeps wood from disintegrating

With a stovetop smoker, you can create awesome smoked foods from the comfort of your own kitchen. Commercial stovetop smokers work well, but it’s fun and easy to make your own from common kitchen items.

Again – don’t set off those smoke alarms! When smoking indoors, run an exhaust fan or put a fan in the kitchen window.

Because nothing says you’re a serious outdoorsman like building a house in your backyard for smoking meat.

Just know that if you build a smokehouse, it won’t get very hot.

But that’s OK. Old-fashion smokehouses were originally used to preserve meat. This is best done by smoking very slowly – with little heat, and sometimes for several weeks.

Build a smokehouse if you:

  • Want to cold-smoke / preserve food
  • Smoke often
  • Smoke large quantities at a time

They’re practical, convenient, and are built on 100s of years of tradition.

When building a new fireplace, why not build in an attached smoker?

The benefits include:

  • Practical
  • Efficient
  • Comfort of own home
  • Can double as wood-fired pizza oven
  • Adds “rustic” look


Many of the earliest medieval kitchens (called “smoke kitchens”) often had no chimney. Instead, above the open fire pit hung a large smoke hood – made of wood and covered in clay.

Cooks hung meat in the smoke hood, which was smoked by the cooking fire below. The fire also served as a main source of warmth and light for the house.

Later, smoke boxes were added to chimneys and fireplaces. These were popular in pioneer America and are still quite popular in backwoods / farm areas around the world.

For more about fireplace history, see:

Now, you too can enjoy this ancient tradition from the comfort of your own home.

Propane / Gas Cylinders

Some of the best homemade smokers start with a large gas cylinder.

Whether you mount it to a trailer or build it into a backyard setup, these smokers produce great BBQ and can even get large enough to hold 2 whole hogs!

Keep in mind, when it comes to modifying these big tanks, some assembly is required.


Propane tanks store propane – a highly flammable gas. Put that inside of a metal tank, and you’ve got a bomb.

Assume that any propane tank you get still contains gas – no matter how old or how long it’s been out of use. Before you make a cut, purge the gas.

The easiest way to purge is to fill the tank with water and let it sit for a week or two. For added cleaning bonus, add soap.

Then, make your first cut into the water-filled tank with a cutting torch or Sawzal.

Drain the water, blow out the tank with an air compressor, and you’re good to go.
