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.

Half-Baths | Utility Bathrooms

Half-baths, also known as utility bathrooms or powder rooms, are minimum bathrooms that have two of the four main bathroom fixtures—typically a toilet and sink. Used primarily for short term visitors, half-baths are often found near the main entrance of a space and offer guests an easily accessed bathroom. When laying out a new floorpan or renovating an existing space, it is commonly recommended that adding half-baths, or converting existing closets into half-baths, is a strategy that adds higher value to real estate. Half-baths are designed with a variety of layouts that can be differentiated as linear, single wall, or split plans.

Split Bathrooms

Split bathrooms are designed to further separate bathroom uses into a primary sink and entry area and a more private bathtub and toilet zone. Divided by a central pocket or swing door, the split bathroom is ideal for shared bathrooms where one user desires additional privacy without restricting another persons access to the entry sink and vanity area.
