The sink has no cupboard underneath it, so the only storage is the small shelf above the toilet, the small medicine cabinet, and the [small] space on top of the toilet tank, which is where T puts his toiletries of course.
But where to put the leftover cold medicine, the aloe for sunburns, the vitamins, extra band-aids, etc? I *almost* spent $35 on a particle board cupboard from Target to mount on the wall in an awkward manner. Instead I found this rusty, dirty metal sliding door shelf at Urban Renewals for $4:
It looks deceptively clean and nice here, but it had been at the thrift store for over a month, untouched and in the corner. Quick measurements showed it would in face fit in our small bathroom! All I had to do was slap on a few goats erm... Coats of white spray paint, and screw it into the wall:
Yes, it's in an unconventional place. I've never seen a medicine cabinet over a bathroom door. But it was perfect, unused space, and I don't need my anti-itch gel or antacids all the time, and when I do, I can stand on the toilet to get them.
Say "Yay!" for bathroom out of the way bathroom storage that cost just $7!
