Yes. Wearing gloves is the very minimum needed to prevent bacterial infections when cleaning. The sinks in the bathrooms and kitchens, as well as the toilet, are perhaps the most often cleaned areas in your home. Unfortunately, salmonella and E. coli bacteria flourish in these three settings. If you use your bare hands to clean them, you might expose yourself to harmful bacteria and viruses. It's not enough to wash your hands after cleaning; you must do it properly to eliminate any chance of spreading germs. Don't put yourself in harm's way; use gloves instead.
