Repurposing an Elevator Locker into Bath Storage

Hubby and his friend brought the vintage elevator locker into the house this weekend. Hubby wanted it out of his garage, and when he's motivated, he finds help!

Unfortunately, I was not as prepared, e.g. I did not power wash the greasy beast before moving it into the main level bathroom. So today, the locker and I bonded, over a bucket of soapy water.

Here's the pics of what will be our new bathroom storage cabinet. Pics of the interior of the locker to be revealed after I figure out how to hang shelves on metal. Any ideas?
