Can you move the outlets? I'd put shelving/cabinetry on the long wall for maximum usage and then your hanging items (vac, dry erase, etc) on the shorter wall. I had a similarly sized pantry, but with door in the short end, and ran ~ 12" deep shelves around all three sides. That was more than enough depth for canned goods, cereal boxes, extra serving pieces, paper towels, etc.

Thank you! The outlets can be moved just was trying to avoid that to get this project done quicker haha. I like the idea of the dry/erase board on the wall you can see from the kitchen.

My pantry is 58"x14' long with the door on the short end. I debated for a long time on shelves/cabinets and finally decided to go with 3 Ikea HAVSTA Storage units along the long wall and 24" butcher block countertop along the back short wall with a mini-wine cooler & a single HAVSTA base cabinet underneath (pulled forward to make up for the 6" depth difference). The base cabinet is 18" deep and the top shelves are around 12". They work great. The base cabinets are a nice depth for things like bulk paper towel storage and Sam's Club size snacks for kid's lunches. The upper shelves are a nice depth for can foods where nothing gets lost in the back. Unlike a lot of the ikea shelving units, these are made from pine so there are no issues with sagging shelves. (Some Pinterest photos I've seen of Ikea PAX used as pantry shelving were sagging.)

I'll try to attach a link to a similar setup on the Ikea website. (As with most Ikea products, there are a bazillion configurations!)

I have something like this Ikea HAVSTA triple setup with doors on the base cabinets, but not on the uppers. My middle upper cabinet has doors, but after I bought them, I decided it would be more efficient without them. The upper units with doors have a back panel, so you can't access electrical outlets without cutting holes in it. The upper units without doors do not have backs, so I can access my electrical outlets. I got a matching paint color and painted the wall behind the units so it looks pretty and I don't think anyone has noticed two are painted and the 3rd has the back board.

Thanks @Becky we are doing pax for our master closet so I will definitely look at this when we go to Ikea to get that. I love this! Do you have any pictures?

I'm attaching photos, but pardon the mess. I was rearranging the pantry last week when the kids got sick and I had to stop mid-project. These aren't really Houzz worthy photos, but hopefully, they're good enough to give you some ideas. :)

BTW, I did Pax in our closets too and am very pleased. We saved a ton of $ using Ikea products for the closets and bedrooms.

@Becky that is amazing thank you! I love the color too!

@itsourcasa Thanks, we were originally going to get white, but they were sold out when I placed my order. Happy accident! I really like the gray. Also, I forgot to mention my pantry is 14 feet, but the length of the pantry shown in the photos (from the edge of the first shelf to the wall behind the butcher block) is just under 12 feet or about 142 inches.
