"Have you ever noticed that a lot of decorators put a spindly-legged chair or side table in the bathroom? It's not just a prop for holding a pile of picturesque, perfectly folded towels; it can make the room feel larger, too. You can see under the chair's legs, which creates the illusion that it's not taking up nearly as much space as, say, a shelf; and, it works just as well.
Many people choose an opaque shower door to add a sense of privacy, but doing so can also chop your space in half, divvying the bathroom up into a shower space and a sink area.Those 3 inches may not seem like much, but they can expose a whole extra row of tile, making the room appear a bit bigger."
