Swimming pool must not become a part of your house. Many people locate their swimming pool directly behind their house, this is not recommended in feng shui. If you already have one then you can try separate it from your house by closed doors. If you insist to have a swimming pool, then it should be located in front of your house. Rooftop pools are thought to symbolically ‘drown’ the residents and weigh them down while pool in the basement is considered a destabilizing influence.
