How to create more storage space in bathroom

Shelf above a door in bathroom

I first found this great storage organizing idea on TipJunkie

A lot of us with smaller bathrooms in apartments or anywhere we are tight on space have a creative way to add more storage.  Build a shelf with two brackets and a board above a doorway to create extra storage for baskets, linens, toiletries, etc.

The idea came from MarthaStewart Home and Garden.  In her,

Install a Toiletry Shelf

Make space for supplies over the bathroom door so that they'll be accessible when they need to be replenished. Use wood screws to secure a pair of wooden shelf brackets to either side of the door frame; screw shelf to brackets. The shelf should rest on top of the door molding, which will help support the weight. Keep small bottled items and toilet paper in handled boxes. Bars of soap can be stored, unwrapped, in an airtight glass container.
