I don't have this exact set up but its a really cool way to add space in the laundry room. Plywood as a laundry room counter top, just rub on some danish oil. (add a cheap rubber floor mat between the wood and metal to dampen the sound)

Rubbermaid Reveal Spray Mop Kit - My floors seemed to become sticky so I purchased this at the advice of my mom. She told me to use a solution of Vinegar, Amonia and 1 Qt. of water. I purchased the mop to help apply the mixtures.
