This is a very good question! I've lived in house shares and can tell you now that no one else ever cleaned the bathrooms. (or anywhere else for that matter). Having a daily bathroom cleaning checklist didn't work, neither did a cleaning rota or timetable.I quickly realised that a lot of people don't care about living in squalor. therefore, if you want to have a clean bathroom the chances are you'll need to clean it yourself! It will be great practice for when you have a spouse and kids! Do a few jobs off the printable bathroom checklist and you'll soon see that it stays reasonably clean even when you're the only one in the house cleaning it!
