Floating bath shelves are best to keep your bathroom looking simple and minimalistic while also adding functionalities. These shelves do not take up much space on the wall either. But one downside of floating shelves is the limited storage capacity. All floating shelves come with a mounting block as well. The mounting block will be attached by default to the back of the shelf. To install the shelf, you first need to remove the mounting block. You can attach this on to the wall using a drill and screws the usual way. Finally, latch the floating shelf onto the mounting block.
