Put shelf under washer dryer. small laundry room mud room makeover, with pedestals and shelves, Tremendously Thrifty - love the storage under the W - but I'd want it to line up with the footprint of the machines.
Organize cleaning supplies under the kitchen sink with built in drawer organizers. Can also use same idea with beauty supplies in the bathroom. I like this drawer cause it's more childproof than cupboards.
