Consider using light and neutral colors on the walls and floor to make a small bathroom appear more prominent. Incorporate mirrors to create an illusion of depth and reflect light. Choose space-saving fixtures like wall-mounted sinks and toilets. Eliminate visual clutter and opt for open shelving or hidden storage solutions. A frameless glass shower enclosure can also add a sense of openness to the space. Proper natural and artificial lighting can play a significant role in making a tiny bathroom feel more spacious.
