Build a Walk-In Humidor

For owners a large cigar collection, cigar-shop owners who don't want to deal with contractors or cigar aficionados who have a spare room and have been itching for a new home-improvement project, building your own walk-in humidor can be a cost-effective and rewarding experience. Although this project is a major undertaking, it is far from an impossible one and will add a unique addition to your home or business.

Step 1

Pick the room you would like to use for your humidor.

Step 2

Install ceramic floor tiles. The room will be very humid, and ceramic tiles are resistant to warping in humidity.

Step 3

Install 100 percent Spanish cedar wall panels. Although paneling an entire room with Spanish cedar can be expensive, it is the preferred material. Other types of cedar may produce odors that can ruin cigars.

Step 4

Install 100 percent Spanish cedar shelves. For display purposes, the shelves should be installed at a 40 to 45 degree angle. The shelves must be slatted to allow for air circulation.

Step 5

Install recessed lights with either LED or compact fluorescent bulbs. Incandescent bulbs give off too much heat and can adversely affect the carefully managed temperature and humidity of the room. Do not point the lights directly at your cigars.

Step 6

Install an automated humidifier and a thermometer to monitor temperature. The size of the humidifier will vary, depending on the size of your humidor. Follow the 70/70 rule: 70 percent humidity at 70 degrees F is the perfect temperature for cigars.


If, for financial reasons, you have to choose between cedar paneling and cedar shelves, pick the shelves. Although not every humidor has cedar paneling, cedar shelves are a necessity. If you don't use cedar paneling, forgo wooden paneling altogether and use a non-organic paneling such as plastic or bare concrete.


This project is a major undertaking and should not be done by anyone uncomfortable with installing floor tiles, wall paneling, lighting fixtures, shelving or automatic humidity systems.
