A toilet fetish fantasy involves a sexual interest or arousal related to toilets, bathroom activities, or bodily waste. Individuals with this fetish may experience excitement or gratification from various aspects of using or being associated with toilets, such as urination, defecation, or other bathroom-related behaviors.

In some cases, the fetish may involve scenarios where individuals fantasize about observing or participating in bathroom activities with a partner. This could include acts like watching someone use the toilet, being watched while using the toilet, or even engaging in sexual activities in a bathroom setting.

The fetish may also extend to specific objects or elements commonly associated with toilets, such as toilet seats, urinals, toilet paper, or bodily waste itself. Some individuals may find the sounds, smells, or visual aspects of bathroom activities arousing.
