The invention discloses a toilet with a water-heated seat. The toilet comprises an integrally formed toilet body, a toilet cover, a seat rotating seat and a hollow seat. The toilet cover is rotationally connected to the toilet body, the seat rotating seat is fixedly mounted at the upper end of the toilet body, and the hollow seat is rotationally connected to two ends of the seat rotating seat to allow a user to sit on. An ozone generator is mounted in the toilet body, a water storage pipe is fixedly connected in the toilet body, and an ultrasonic atomizer used for atomizing water in the waterstorage pipe is mounted at the lower end of the water storage pipe. By heating of the hollow seat with water, potential safety risks in electric heating of the toilet seat are eradicated; by adjustment of the hollow seat through water temperature, heat dissipation is slow due to high specific heat of water, so that continuous heating of the hollow seat is avoided.
