The main bathroom in your home should always be as spacious as possible, being at least more spacious than any other bathrooms you may have. What makes this one work so well is the fact that they sued the color white so liberally. What keeps the space form being glaring is that they used differing shades of white. What this does is help offset the overall light of the room and keep it easy on the eyes. The use of white also makes the room look bigger, as does that large window. The actual space itself is a good size; it is just that this is accentuated by the color and the window.
