Most succulents dislike being kept in the bathroom. They prefer to be kept outside, where they can receive more sunlight and be kept away from the humid environment.
However, some succulents such as Aloe vera can be grown in a bathroom.
Light is a big factor when growing succulents. You want to provide enough light for the plant to get sunlight, but not too much light that it gets scorched.
If you put your succulent outside during the summer months, do so.
