I don’t have a lot of details about where is the outdoor shower located but it doesn’t really matter because if you have a garden I think you can easily create something similar. Of course, if you don’t live in a place where is warm weather all year round you need to use pots for the plants. And you need to work harder to keep it green because in the winter everything goes away.
Preferably you need plants that love humidity and water . Thin tree trunks will complete the decor and will keep you and your family away from the outside eyes. They should be tall because nobody wants to be spied when they shower, right?
Imagine showering in the morning before going to work here. It will bring a smile on your face that will last all day. Trust me!
