If you have a shower that doesn’t have built in storage areas, this could be your answer. These are really easy to install. The waterproof stickers are super strong. I was somewhat shocked at how strong they really are. These shelves fit in a 90-degree wall corner. The shelves would not fit perfectly in the corner of my tub/shower combo. Only one side of the shelf would connect to sticker holder. I put all the bottles of stuff you would normally find in a shower on the shelf and it held! With only one side connected!
