Light, cool colors are often recommended for small bathrooms to create an illusion of space. Soft blues, light grays, and pale greens can make a bathroom feel larger and airier. These colors reflect light well, brightening the space and giving it a clean, fresh appearance.
However, don't be afraid to consider darker hues for a small bathroom. Deep, rich colors can create a cozy, intimate atmosphere when paired with proper lighting. For instance, a dark navy or forest green can add depth and sophistication to a small space, especially when balanced with white fixtures and good lighting.
