It had 5 shelves from ceiling to floor and was so deep. You could store a lot of stuff in there, but you couldn't get to over half of it with out pulling a bunch of stuff off of the shelves.
We checked at all the local hardware stores and were not happy with all the wasted spaces they left in the cabinet. I talked with my son and wife about a 6 shelf Lazy Susan pantry cabinet design with back shelves that used all the space and wasted very little.
Our pantry closet is 27" wide at the back and 41" wide at the front, 23" deep, and 76 inches high. The closet is very large and can hold a lot of food items.
We needed to make the Lazy Susan large so that we could reach into the back of the pantry. We decided to make the lazy susan shelf a half semi circle with the pivot point at the front of the pantry door.
The trick was to find the center of pantry entrance and still clear the pantry door as the Lazy Susan swung around. Once I found this point I mounted a 5/8 inch pillow block bearing to the top inside of the pantry door to make all other measurements. I hung a plum bob from the pillow block bearing to the point I marked on the floor as the center of the pantry door.
You should make a template out of poster board of the pantry cabinet floor to make your measurements and drawings. Each shelf may have an unequal dimension as the walls are not square, so determine the largest and smallest size. You need one set of dimensions that will work for all shelves. The shelves can then be cut to the smallest size and they should fit in any place.
We reviewed the design and determined to proceed. We decided that the best color to paint the inside of the closet is a solid white color so that it would make it easier to find items on the back shelves. We decided to stain all the oak plywood panels a natural oak color.
