I believe I just answered this for you a few minutes ago and I need to correct myself and add more info to this (for obvious reasons)
I hope you received this corrected, more thorough info in time:
A better explanation with considerations is as follows:
The CF091 (which is what I have) is measured as follows: Base is 12" Wide x 9 1/2" Deep (including a "wrap-around" cord-storage at right rear that sticks out about a 1/2" from back) , The Machine is 15" Tall but you will need an extra 1 1/2" approx. to remove the water reservoir or an extra 4" to open the lid on top to fill it with water without removing the reservoir. But if you have close tolerances, it may be easier for you to just remove the reservoir in order to fill since it obviously may be difficult to do if you don't have the space. I ALSO have to note that the unit produces steam from the top through vents, so it may affect the bottom side of your cabinet over time. Or if you have the space, simply slide the whole unit from under your cabinet while brewing. I hope this helps
