What types of cleaning products do you really need to clean the bathroom?

I mean, every market has 2 or 3 whole aisles dedicated entirely to cleaning products and each seems specific for one thing only. I feel like some soap with a disinfectant is enough, but most people I know do a whole 3 stage cleaning ritual - soap (and rinse), disinfectant (and rinse), bleach (and rinse to finish)
