I have one 15 inch upper and I use it for large spice containers and oils (other spices are in a drawer). I wish it was a little bit larger/wider. Do you have any idea what you might want to put there?

They are on the right side of the sink and above a dishwasher so I'm thinking bowls and glasses. I have another 15 on the left side of the window which i'll be putting all the spices and oils in there. I think the designer just did the 15/33 combo so I'll have 15 on both side of the window.

blfenton - yes these are uppers. May I ask what you put in your 18"?

my 18" will have all of my tea and coffee supplies. the 17" (yes weird) will have special oils and vinegars.

15" is good for drinking glasses. esp if you have the stacking kind.

Ok, too coincidental. I have 2 - 18's. One has my mugs and my tea and coffee supplies. The other one as my special oils, vinegars and spices.

My 30" one, which is right beside the 18" with the mugs, has my dishes (plates and bowls) and glasses and both those cupboards are above my DW.

I have 3 18" cabinets and one 21" upper cabinet. I find I use the space well when I keep smaller items (oils, baking supplies, canning miscellaneous) in them. In the ones where I have bigger stuff, like a salad bowl, mixing bowls, there's a lot more wasted space since one salad bowl uses most of the width. My preference would be for one wide cabinet like your 33" to keep big plates, etc., and one narrow cabinet like your 15" to keep smaller stuff like glasses and bowls.

I would mark off the interior space on a flat surface (consider if your face frames to block part of the access). Put the stuff you want to store in the taped off area to give you a better idea of what might fit. You might only get one stack of bowls there, and maybe 3 columns of glasses.

In my old kitchen, I had a corner cabinet with an angled door that was maybe 15". I used it for glasses. There was plenty of space in the cabinet, but the door really limited access and I hated it.

If possible, consider a drawer for smaller spices or else they will be buried behind one another and difficult to locate and access.

I have a 15 inch wide upper cabinet on both sides of my window. They are 9 inches deep. (That's right 9 inches). My cabinets are all 36 inches tall so it gives me 3 reachable shelves. I can get 5 mugs per shelf. This was done to give some interest to the window area since there are 12 inch deep cabinets beside each 9 inch. It looks great! They are close to my coffee bar (3 different types of coffee machines) so I keep coffee cups in them along with small juice glasses. We always have juice in the morning before we have coffee so it works good for the 2 of us.

I have one 13" cabinet in which I house cookbooks.

Coffee and tea supplies and mugs in mine. It's also a good size for pet food cans.

I have four 18" uppers, and I keep all kinds of things in them. A set of dishes in one. Lunch items (peanut butter, granola bars, etc.) in another. In another, one shelf has cookbooks and other shelves have prep tools/dishes, sugar bowl, salt/pepper, wine glasses, overflow glasses, etc. 18" cabinets hold a lot! Consider making your 15" cabinets 15" deep - they'll fit even more! (My 18" cabinets are 15" deep.)

Here are a couple of examples:

I have 15" cabinets on each side of a window. The one on the cleanup side has glasses and mugs; the one on the prep side has food (canned and boxed things). We don't have a pantry. They are a huge improvement over the 12" uppers I had previously!

I got extra shelves for both - like in Buehl's photos, each shelf is only as high as it needs to be. I get much more efficient storage when I don't need to stack things.

"I got extra shelves for both - like in Buehl's photos, each shelf is only as high as it needs to be"

I had extra shelves put in the cab to left of my sink for dishes. I have a set for 4 so didn't need the height normally given for a shelf. I use one for plates and paper plates (I mostly use) and mugs. and another for soup type bowls.

the cab to the R of sink is for glassware - of which I have little. I don't use them for me, just company. I use my mugs.

I have a 9" cabinet which holds my teas, drink mixes, coffee and coffee filters. The coffee maker sits below it on the 9" bit of counter. My lone 15" cabinet is next to the fridge and holds my cookbooks, water bottles, coffee travel mugs and random manuals and any overflow of little-used items. 15" is a tad narrow , even for frameless like I have-- it will be okay if that looks best in your space, but I would rather have two 24".
