I would do a 3' cabinet for the W/D that you keep brooms in and a 3' pantry cabinet.

Also I would plan on having drawers for the lower portion of the pantry cabinet equal to the height of the W/D Doors (assuming 3').

Also Keep in mind the cabinets for W/D will be custom. Not something you can buy from a stock cabinet as it will need to be open tot he floor to support he weight of the machines.

Whenever I face a situation like this, I draw it out to scale. Takes the mystery out of it.

If you are looking for inspiration photos, try searching for Wardrobe Wall. It is a different purpose, but similar idea of a mass of cabinet panels and drawers that spans several feet wide. That first pic looks good to me, actually.

Thanks everyone for the feedback.Diana, yes, last night I sketched it out on graph paper. I'd have two doors 18" wide (for the W/D) and then three 12" wide (one for broom closet; the pair for the pantry). I did not love it.

Jan, I think you may be right (again! Does it ever get old? lol). I think I will either do something like the pic above with the white cabinets and the W/D (so a 30" pantry on the right, and the rest for the W/D and stash the broom in there). Or even just split it 3' for W/D and 3' for pantry. I feel like I need all the storage I can get. I had hoped to stash a bunch of stuff in this broom closet, like my tall step stool, ironing board, drying rack etc. But I can get creative.

BTW, I have friends whose cabinet maker did something like this (below). Just a simple pull out between the fridge and their wall. (not inside a dedicate cabinet). It's 2-3" wide and maybe 12 inches long. They only store 1 broom (sideways) and a dustpan. FWIW, their cabinet maker just attached a piece of wood to the regular sliding hardware. The cabinet above their fridge stretches to the wall and this will thing mounts on the bottom of that cabinet. You wouldn't know if it's there, unless you look. Maybe something like this next to my fridge??? Or maybe I'll just be low tech and put a hook on the wall next to the W/D.

Pocket doors will take up any space to the side of the washer where you might have stored brooms on hooks. The hardware is also very prone to breaking. Especially large cumbersome single piece ones like that that will also be a big challenge to keep from warping.

You may hate bifold doors, but in many ways, they provide better utility. So would multi panel bypass doors. So would a standard single drywall closet, instead of separating it into two sections. It would be a lot cheaper too.

GreenDesigns, the cabinet makers I spoke to would add a partition between the door mechanism and the W/D, so the side of the cab would be free. Are they prone to breaking? I saw a demo and it looked smooth. The cabinet maker had one on hand that he was currently building. He said they used to build a lot of TV cabinets with those doors, then with the slimmer TVs, that fell out of favor, and now they are back again. If I didn’t use the pocket door my thought was just a pair of 18” doors. I have 46” clearance between this cabinet and anything else. Hmmm.....not using the pocket doors would save me 5”. Hmmmm.....

GreenDesigns, you mentioned warping. I plan to have a large door there, no matter what type of hinge I use. Is this an issue for all large doors, that they are likely to warp (?). Or is it more of an issue w/ pocket doors, that even a little imbalance could become a problem? Thanks

Doors that tall should be 100% MDF. Wood will warp. Any wood cabinet that's over 48" needs to be 2 separate doors. Even in some climates with wide humidity swings, 48" is too tall to not warp.
