Wooden crates add cozy texture to your cabinets while providing sturdy modular storage. Stack them horizontally or vertically to create open cubbies for extra toilet paper rolls and folded washcloths. Their rigid structure supports heavier items, like gallon jugs of shampoo refills, with ease.
12. Mount Magnetic Strips for Grooming Tools
Fasten a strong magnetic tool strip along the inside frame or door of your vanity cabinet. It provides a secure magnetic spot to hold metal nail clippers, tweezers, bobby pins, and cuticle trimmers.

Breathable metal mesh baskets are ideal for humid bathroom environments because they allow airflow and resist rust. Choose modular versions that stack on top of one another to build a customized storage tower around your pipes. The open mesh allows you to quickly scan your inventory before heading to the store.
