An intelligent toilet or smart toilet (sometimes referred to as a modern day bidet) is a bathroom plumbing fixture or type of electronic bidet toilet which incorporates traditional bidet cleansing (for genital, buttocks and anal hygiene), with the added enhancement of modern smart home technology.

Modern intelligent toilets incorporate electronic bidet cleansing functions into a ceramic toilet bowl for a low-profile and modern aesthetic. Intelligent toilet bidet functions are managed through voice command, mobile app or remote control navigation, depending on the toilet's manufacturer, make and model.

Lower-cost options include a detachable toilet seat referred to as an "electronic bidet ("e-bidet")" seat, which are becoming increasingly popular as well.

Modern high-efficiency intelligent toilets also use 1.0–1.28 gallons of water per flush, reducing water consumption and waste as well.

In the 1700s, Bidets introduced throughout numerous European countries as a standard for hygiene and in some countries, contraceptive measures.

Electronic bidets are introduced around the world in the 1980s with popularity slowly growing in Japan, Europe and North America.
