If you're looking for interior design tips for organizing classified documents in your bathroom, I suggest opting for neutral colors like, off-whites, Ivory, taupes and creams when choosing boxes. To create visual interest, use boxes of various sizes and arrange them in a staggered manner to add depth to the space. For an efficient layout, consider stacking the majority of the boxes on one wall, while keeping your most current reading materials within reach of the toilet. As a final touch, placing a candle on top of your current reading box can add a nice aesthetic element to the arrangement.
