What's the big deal with building your own DIY walk-in humidor? Well, for starters you can save some serious coin. A walk-in cigar box is an affordable project that requires less effort than you think—and considering how much cigar enthusiasts spend on quality products, the costs are worth it. Many cigar smokers build a walk-in humidor for less than $3,000, while having the ability to choose from a wide range of style and functionality options.

DIY humidor rooms are great projects for seasoned cigar lovers who have been collecting cigars for years. If you are a cigar aficionado like this, then you have extensive knowledge and taste when it comes to taking care of your prized collection. Cigar smoking means more to you than just something to look forward to on the weekend. It is a significant part of your lifestyle, so the walk-in humidor cost is important for you.

This group also includes customers who tend to collect more than they smoke! These cigar lovers always have an exceptional collection on hand, and a walk-in humidor is a great place to keep your cigars safe without worrying about space constraints.

Humidors are a great way to keep your cigars fresh, so it's no surprise that people have questions about them. This article will answer some frequently asked ones for you!

What is a walk-in humidor?

A walk-in humidor is a space for storing cigars in an environment where the humidity and temperature are controlled 24/7. This preserves the quality and freshness of the cigars to ensure they have enhanced flavor over time. There are different shapes and sizes of walk-in humidors available, depending on how many cigars you plan to store and collect. Many of our walk-in humidors come with water tanks if you don't have access to a water supply or drain.

What are the benefits of building a walk-in humidor?

There are many benefits of building a walk-in humidor. You can collect a larger volume of cigars without worrying about their quality diminishing if they're stored incorrectly. You can also organize your cigars to make it easier to find a specific product that you own.

DIY walk-in humidors allow you to display your cigars in a beautiful arrangement to show them off to your friends, family members, and guests. This can allow you to see every item in your collection to ensure they're spread out in small rows and are easy to choose from. Plus, your guests will marvel at your class when you tell them that the whole unit is custom!

Walk-in humidors are a luxurious addition that enhance the quality of your home or office. Similar to a wine cellar, they make it easy to access your cigars and spend more time browsing through the available options. They're even large enough to accommodate one or two people.

How many cigars should I have to build a homemade Cigar Humidor Room?

This question depends on the amount of space you have to build your walk-in humidor. A small closet (3 ft wide by 6 ft high) would be the smaller end of the range and would fit a collection of 12-15 cigar boxes.

A larger walk-in closet will fit more cigar boxes based on the amount of shelving available. A good rule of thumb to use is approximately 3-4 cigar boxes per 4 ft - 8 ft shelf (of course, you can try measuring your cigar boxes and shelves at home to be sure). This allows for room between the boxes so they do not appear too crowded.

This image was posted on a website by a gentleman who built this humidor room on his own. He had been collecting cigars for around ten years at the time he built this humidor. Building a home humidor similar to this would cost you less than $4000, including the backing, flooring, and humidification.


How much would it cost?

(2022 pricing estimates) The cost of a 4’ shelf will run around $59 (including brackets and hardware). Depending on whether you are redoing the flooring and backing, you can get this done within a $900-$1100 budget. And it will include a humidifier.

You can go with either a Hydra Large or a Humidifresh humidifier. Humidifresh will cost more, but we are advocates of spending some more money if it can get you a better item that will preserve your cigars better. You can find the Spanish Cedar prices here.

For a bigger DIY walk-in cigar humidor, you would have to double the cost of shelving. Then add in the cost of flooring. It would be best if you also considered Spanish Cedar paneling for the walls. Spanish Cedar wood offers several benefits in terms of cigar storage.

A 4' x 1/4” sheet of Spanish Cedar paneling would cost you around $85 - $90. If you want to add to the looks of your DIY walk-in cigar humidor closet, consider adding some trim. Of course, you’d be looking at some additional costs in that case.

How to pick the right size humidifier?

This part is simple. Measure the size of the room. Multiply the length, width, and height of the room, and that will give you the total area of the space, in cubic ft. Now all the humidifiers in the market clearly indicate how many cubic ft. they can handle. For example, Humidifresh will work well in a room of up to 30-90 cubic ft. space. A room with an area ranging from 100 to 1000 can use an ARIS 826 Humidifier. Consider an Ultrasonic machine for any 800 - 4000 cubic ft. room.

Do I need to hire a contractor to get this done?

Not everyone is a hands-on person who can do everything by themselves. So, you have 2 options.

The first is you can hire a contractor to get this work done for you. The contractor will perform all the calculations and can help you with purchasing the material, or you can choose to get modular units that are pre-made. The good thing about modular units is that they are already made, so all you have to do is simply place them in the space you have. These modular units are used in a built-in wall/closet space or even a big room stand-alone unit.

hey guys, I’m converting my closet into a walk in humidor and was wondering if I could buy the supplies I need from you. The area I need cedar sheets and shelves is about 160ft or so.
