Here’s a bathroom cabinet I tackled a while back. I used adhesive hooks (with a thin metal hook) to hang all of the flat irons and curling irons on the cabinet door. Set aside all of your “thoughts/opinions” on adhesive hooks (most people think they don’t work), these things actually work (when you buy the right ones). The hooks I used here hold up to a few pounds each which is more than enough for the appliances I hung.
If you look toward the back of the photo, you’ll see I used the “J-Pipe” (the annoying pipe under every sink) to hang the blow dryer. Blow dryers usually fit nicely in this awkward space.
On the bottom shelf of the cabinet, I sorted all of the makeup by category and stored each category in deep pull-out organizers.
