The trouble with those shower caddies that hang from the shower head pipe is that you have only one showerhead. To get more space for your bath potions, hang another caddy on a cabinet knob. With a No. 8-32 hanger screw, you can screw the knob into a stud. To fasten to drywall, use a screw-in drywall anchor along with the hanger screw.
Mason jar wall hanging for q-tips, brushes, tubes. Perfect for those who don't care for the messy bathroom drawer.
Plant holders make great hair styling supply holders. Instead of hanging plants in them, you just mount them to the wall and put your blow dryer, curling iron and other hair supplies inside. They look great in the bathroom and help you to save a bit of cabinet space.
