The biggest myth about building a walk in humidor inside a house is that it costs a lot of money and you have to be filthy rich to have one in your home. The reality is that I have known many cigar smokers who have built such a humidor for less than $2000 total and did not spend anything crazy to buy a whole lot of cigars. As you would imagine that nobody who just started smoking cigars would just build something like this. These guys have a collection from 4-10 years or even more that they have been smoking some and collecting more than they smoke. If you buy cigars regularly then you know you do not end up smoking all your cigars. Here are some of the frequently thought about questions on this topic:
This image was posted on a website by a gentleman who has built this humidor on his own. This gentlemen has collected cigars for around 10 years at the time he built this humidor. To build something like this you can get it done under $3000 that will include the backing, flooring & humidification.
(2020 pricing estimates) The cost of a 4’ shelf will run around $45 and add some brackets and hardware. Depending on if you are redoing the flooring and backing you can get this done under a $600-900 budget. That will include a Humidifier. You can go with either a Cigar Oasis Magna 3.0 or a Humidifresh. Humidifresh will cost more but I am a big advocate of spending more money and getting a better item to preserve your cigars better.
For a bigger walk in Humidor you would want to double the cost of shelving. Add in the cost of flooring. You should also considerSpanish cedar paneling for the walls. A 4' 1/4” sheet of paneling will cost you around $85-$90. If you want to add to the looks and add some trim you are looking at some additional cost.
This part is easy. Measure the size of the room. Multiply the length, width and height of the room and that will give you the cubic ft space. Now all the humidifiers in the market will tell you how many cubic ft they can handle. For example Humidifresh will work well in a room for upto 30-90 cubic ft space. A room from 100-1000 can use an ARIS 826 Humidifiers. Consider Ultrasonic machine for anything from 800-4000 cubic ft room.
Not everyone is a handy person and get all this done themselves. So, then you have 2 options. You can either hire a contractor to get this work done for you. Contractor will do all the calculations and can help you with purchasing the material or you can get the modular units that are pre made. The good thing about the modular units is that the will be pre made and you just place them in the space you have. These modular units can be used in a built in wall/closet space or a big room stand alone unit.
