Illustration of a common efficient full bathroom layout with side fixtures

Bathrooms are rooms used for personal hygiene and include specific bathroom fixtures such as sinks, toilets, bathtubs and showers. Variations of bathroom layouts include minimal utility bathrooms, full bathrooms with included bathtubs or showers, ensuite bathrooms attached directly to private bedrooms, and jack-and-jill bathrooms split between two separate bedrooms. In real estate, a full bathroom contains four fixtures, a three-quarter bath contains three fixtures, and a half bathroom is limited to only a toilet and sink. Bathroom layouts should take into consideration additional spaces required bathroom accessories such as towel bars, mirrors, and storage, while also providing comfortable and safe clearances for general movement and usage. Bathroom dimensions will vary on a case-by-case basis due to variations in actual sizes of fixture.
