If you use it in the bathroom, where possible, store it in the bathroom.
For items you can't live without e.g. toothpaste, shampoo, toilet paper... ensure there is a space allocated to store the replacement product i.e. 1 toothpaste currently being squeezed to death in the drawer and a new one below ready to replace it.
Hint: When looking for baskets or containers to fit a specific spot, write down the maximum space available Height, Width and Depth and carry these measurements with you until you find the right sized container.
