How To Build a Walk-in Cigar Humidor

If you buy and collect premium cigars in quantity and have outgrown your humidor, consider a walk-in humidor. Because they can be expensive, convert a closet into a humidor with a carpenter's advice.


  • Step 1: Add a small air conditioner to the closet/walk-in humidor. Know that this can require added maintenance like the regular disposal of residual water.
  • Step 2: Add a humidistat or digital hygrometer to measure the room's humidity level.
  • Step 3: Install a glass door with wooden hinges. Frequently open and close the door to keep the room properly ventilated. Now enjoy your new and practical use of a closet.
  • FACT: The slang term "stogie" comes from the old west Conestoga wagon drivers who often favored long thin cigars.
  • Step 4: Install ceramic floor tiles to absorb humidity. Nail Spanish red cedar panels to the wood framing according to plans. Install Spanish red cedar shelves.
  • TIP: Spanish red cedar is a wood that's most often used for humidors. It's mildly aromatic and absorbs humidity.
  • TIP: Cigar connoisseurs recommend keeping a humidor at 70 to 75 degrees to maintain a steady tobacco moisture level.
  • Step 5: Remove the closet's door, along with any coat racks and/or shelving. Staple a plastic moisture barrier to the closet's interior walls.
  • TIP: Improperly humidified tobacco can become either too moist or dried out.
  • Step 6: Hire a carpenter to draw up plans and do rough wood framing in the closet. Buy 3/8-inch Spanish red cedar panels that conform to the plans.
  • Step 7: Find the right closet in your home for the humidor. The closet should be away from direct sunlight, and within 5 feet of a 110-volt wall outlet.
