One of our favorite tricks for organizing a space is simply dumping like things into their own box or container. In the bathroom even when we've gone through and gotten rid of everything that's cluttering it up, we're still left with enough stuff that if we don't contain it somehow it'll overtake the counters and start making us crazy.
We love this example of how like colored containers on open shelving in the bathroom can make order out of chaos. Thankfully we don't have that much stuff but this goes to show that sometimes open shelving can be neater and easier to access than a whole wall of cabinets. Try containers from from Ikea or the container store for affordable versions. Or make your own by using a version of these custom magazine files.
