Most homeowners believe that there should be at least two bathrooms for every three bedrooms. For example, if you have a three-bedroom house, there will most likely be one main bathroom for adults and one family bathroom for children and other family members. But this isn't true for everyone. Some houses have more than two bathrooms while others have only one or none at all. The number of bathrooms in your home is often based on the number of people who live there. If you plan to have more than four people living in your home, then you should have at least two bathrooms. If not, you might want to look into adding on to your home or renting out rooms in friends' or relatives' homes so you have more space. You can save some money by having one bathroom for every bedroom. But because people usually spend more time in the bathroom than in their bedrooms, this isn't always the best idea. Your decision on how many bathrooms to have should be based on how many people will be living in your home at any given time.
