Mom Hack: if you have teenage daughters, chances are you have a bathroom counter full of bottles, lotions, makeup and mess. Our girls have to share a bathroom with the boys so I shift all their primping gear to their rooms. Each girl has a counter-height shelf (made from an IKEA shelf remnant and some IKEA shelf brackets), a large mirror, and an adjustable stool. For less than $30 I save myself from countless 'She's taking forever in there!" fights.
