9. Under-Sink Storage That Actually Works

The area under the sink is often awkward due to plumbing, but with the right tools, it can become one of the most useful storage zones in a small bathroom.

Use stackable shelves designed to fit around pipes, or adjustable organizers that can be customized to your layout. Clear bins help you see everything at a glance, while pull-out drawers make accessing items easy.

This is a great place to store cleaning supplies, extra toiletries, and backup products — things you want nearby but not on display.
