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.
No matter what kind of wall art you choose to hang in your home. Be sure to get one that you enjoy looking at. Before purchasing wall decor, make sure that that the size is ideal for your wall space. Take note of colors around the room and get artwork that contains some of those colors. Avoid hanging artwork with the same color as your wall to make the artwork stand out.
