In a small bathroom, less is always more. If you include a vanity, you will probably need to choose a very small unit. Depending on your needs, you can choose the style (cabinet or drawers or a combination) that is most suited to your needs. Recessed medicine cabinets (set into the wall, with an unframed mirror) are ideal in small bathrooms.
Finally, turn the area under your pantry shelves into usable storage space with an under the shelf basket. Under the shelf baskets are easy to install and are a cost effective way to add more storage space to pantry. These convenient baskets come in a variety of sizes to fit any shelf and will make finding those smaller items in your pantry easier.
