The invention provides a basin integrated with a water purifier. The basin comprises a basin body and the water purifier, a first groove is integrally formed in the side of the basin body, a second groove serving as a water storage bucket of the water purifier is integrally formed in the position, close to the first groove, of the basin body, a first through hole communicated with a multistage filter element sewage outlet is formed in the bottom wall of the first groove, a second through hole communicated with a multistage filter element water inlet is formed in the outer side wall of the first groove, and a third through hole communicated with a multistage filter element purified water outlet is formed in the position, close to the side wall of the second groove, of the first groove. A fourth through hole is formed in the outer side wall of the second groove and communicated with a fifth through hole formed in the outer edge of the second groove through a water path pipeline, the fifth through hole is connected with an electric control faucet, a water suction pump is arranged at the position, between the fourth through hole and the fifth through hole, of the water path pipeline, and the water suction pump is triggered to be started when the electric control faucet is switched on. According to the basin integrated with the water purifier, water purifier waste water is directly drained into a sewer from the bottom of the basin, and the water leakage accident of a traditional water purifier is avoided.
