Sterilite Medium Shelf Bin with Handles, Plastic Storage Container for Organizing Shelving, Closet, Pantry, and Countertops, Clear, 6-Pack

Image 1: You have the right idea with the bins on the top shelf. Do the drawer things work for you on the bottom shelf? They seem under utilized/ half empty. You could subdivide the drawers and store more things together. You could get a short but wide bin that fits on top of the drawer units. You could replace the drawer units with tall bins and fit two side by side in each space. A tall but open bin will hold the spray cans, mouth wash, and such upright. Image 2: You could do a bin on the left that fits in front of the plumbing. On the right, you could do a two tier pull out drawer organizer or just more bins. It would be helpful to know what you will store here to suggest more options. Under my kitchen sink, I keep my folding dish rack, some drying mats, a bin with dishwasher tabs and rinse aid, dish soap, garbage bags, and folded brown paper bags to reuse. Image 3: I think a real photo would be better and an idea of what you're trying to store here. Are there wire shelves and hanging rod? Is it a linen closet or an entry closet?
