Half-Baths | Utility Bathrooms

Bathroom layouts illustrating the dimensions of utility bathroom floorplans with linear, single wall, and split layouts

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.

Consult local building codes for accessibility requirements.
Overall bathroom sizes will vary based on the actual dimensions of bathroom fixtures.
