Flooring

Bathroom in my mother's home had sink leak which was fixed. Floor is caving in and needs to be replaced and retiled. Toilet and Cabinet also will be replaced. Would like an estimate for replacing the floor. I will separately engage the tile guy and plumber , but need estimate and schedule just for the floor. The only reason we are fixing the floor is because my mom is returning from nursing home and needs to live in the home for another year .
