The 58-year-old woman claimed that she "felt a force holding her down" and said she did not understand why she felt compelled to stay in the tiled bathroom.
According to her husband Kian Ann Ong, she was completely naked throughout the ordeal and only showered a total of 18 times.
He said those were the only times she left the toilet bowl and would imagine that if she left people would throw stones at her or spray her with water.
Ong said that he was the only person who had contact with his wife and she even refused to speak with their 27-year-old son Jiing Yih.
Eventually Ong decided to seek help and called the emergency services who took her to hospital near their home in Singapore.
"They had to come into my flat, hold her down, then wrap her in a towel before using a wheelchair to take her to the hospital," the Daily Mail quoted Ong as saying.
He said that whenever he tried to remove his wife from the bathroom, she would refuse and tell him that something was holding her back.
Leong would also get upset or angry if she heard her husband talking on the phone.
The couple's son, Jiing Yih, a freelance journalist, defended his actions when he was questioned about why he did not step in to help.
"My mum and I have similar personalities," he told The New Paper.
"We're both very straightforward and would frequently get into arguments.
"When she got into that state, her emotions became even more unstable, so I tried to avoid possible confrontations which could lead to blow ups," he said.
Ong said that he found it difficult to care for his wife during that time and considered leaving her but decided against it.
During her stay in the bathroom Leong lived on porridge, bread and biscuits prepared by her husband.
