You can hang this shower curtain with the pockets facing either the inside or outside, depending on what you need to store.
Promising review: “I needed more storage in my shower because there are no built-in niches and I only have room for a narrow shower caddy. I saw this idea on Pinterest, but it was geared toward college dorms and small apartments. I found that it works great in any size bathroom.
It has nine pockets of different sizes, so you can store many different items. The liner itself is of heavy plastic and the pockets are of sturdy mesh. The overall quality is very good and it does not feel too thin. My shower rod is screwed into the wall, so I am not concerned about putting too many heavy items in the pockets, but if you have a tension rod, you should be aware not to overload it.” —Minerva King
