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.
Room and wardrobe organizers. Garments thrown across the floor, footwear dropping from the current wardrobe, absolutely no top area of any home furniture uncovered. Does this seem like your own master bedroom? Setting up a few open up shelves inside your wardrobe and then putting smaller plastic-type storeroom containers and plastic bins on them is actually a sensible way to maintain your room neat. Little plastic footwear storage cardboard boxes may also be bought and piled nicely or put alongside on the floor of your room. In case you have place beneath your bed, lower profile storage bins could be wheeled under there nicely out of eyesight.
