Can you still use the toilet when someone else is in the bathroom?
Yes


Can you use the toilet if someone is in the shower?
Yes, makes no difference to our showers or pressure/temperatures


If someone is in the bathroom, where do you wash your hands?
Laundry, but in our house we have an ensuite so just wash hands there


If the toilet is off the laundry, are you meant to wash your hands in the laundry, or find your way to the bathroom?
Our toilet is right next to the laundry (on one side) and bathroom on the other. I prefer people NOT to use my laundry and often shut the door to avoid it


If there bathroom and toilet are on the opposite side of the house to each other and the kitchen is closer, is it ever OK to wash hands in the kitchen?
Absolutely not!! Only hand washing in my kitchen is after food prep. Never after toileting or general hand washing
