If you are planning shelves for storage in your new bathroom, consider building shelves that are recessed into the wall. These shelves can be either framed with trim or left unframed. Or you can add doors to keep things on the shelves dust free. In a small bathroom, doors with glass or frosted glass doors will make the room appear more spacious than solid wood doors (and frosting creates enough blurring that you don’t need to be quite as neat). You can use the shelves strictly for storage or you can mix storage and display of decorative items. If you cannot or do not want to build recessed shelves, you might consider installing glass shelves. Because they are clear and reflect light, they do not make the room look smaller, as wood shelves might do.
Ambient lighting can be accomplished be placing small halogen bulbs at the back of the painting or decoration pieces housed in their cabinet sections. The textures chosen for this should be as follows. The wall should be painted with a very smooth finish emulsion, wallpapers should be avoided here, and the decoration pieces with their shelves should be dull and matted. They should not be shinny and glittery. Basically their security level should be kept in check.
