My walk in pantry is a bit different in dimensions, but it was already built in when we moved in.

The shelves are in a U layout, utilizing the full sides, then a bit deeper shelf on the back wall. So that's what I would suggest to you, utilize that full 14 inches on the sides, and perhaps a 20-24 inch shelf on the back side?

Thanks BeesNeeds. That's exactly what I was thinking but wanted to hear from others first. Do you feel claustrophobic in your pantry at all? Again, it's not like I'll be hanging out in there but still.

There are dozens of old threads on pantries to search.

Check out the Pantry thread in the Gallery...linked below.

FWIW...12" seems to be the best shelf depth. Deep enough for just about anything but not too deep that things get lost on the shelves. With a 12" depth, you can see everything without having to move anything.

I know you want to use Elpha shelving, but that limits you to 12,16, or 20 inch deep shelves.
I would do permanent built in shelves 12 to 14 inches deep on the sides and 14 to 16 on the back if you have a lot of large items. I have 11 inches on one side of my walkin and I really like it, but 12 to 14 inches would be better. Copco makes a nice canned good holder 12 inches deep. I have 24 inches on the back wall, but I only use the front half and the corners are hard to access because they are so deep.
I noticed that you are planning on storing large items like soda and paper towels. Perhaps the back shelf should be as deep as the soda (bottle, cans that you buy)
We installed our own shelves in our last kitchen and I put the shelves closer together in the middle section (for aluminum foil, etc.. and spaghetti boxes and small items) and then spaced the shelves further apart above and below.
If it's not too late have an electrician put in a door activated light for the pantry.

Our pantry shelves are 14" and 18" deep. The 14" could be reduced to 11" or 12" and still function well. I like the 18" for large and bulky items.

Here's the 14" deep shelves (to be reorganized today - we waited almost a year to get our sprinkler permit signed off but now it is, as is the final permit, so we're done!).

Here's the 18". P.S. I would have preferred wood shelving, but my DH really really wanted this metro-shelving. We just got plastic shelf liners and the difference is night and day (very difficult to use without them).

The white melamine Elfa shelving is a nice option. My daughter has a similar size pantry as you do. She used 9" shelving on the back wall and deeper shelving on one of the side walls. The 4" shelving on the other side wall was already there--she painted those shelves white and sealed it with poly for durability. The 9" back wall shelving preserved floor space which was ideal in her situation and may work well for you too.

Hi all- thank you for the awesome suggestions!!!

I should clarify that I want to use elfa on the door only. The shelving on the walls will be wood.

I spoke with the project manager and he suggested 12' on the sides and I'm blanking on what he suggested on the back wall. Maybe 18?

Let me go back now and take a good look at all of these great pantry photos you've linked. What would I do without this place?!!
