Single-family homes started construction in 2025 typically had two full bathrooms, according to the U.S. Census Bureau’s Annual Survey of Construction.
A full bathroom, as defined by the Bureau, is one that has a washbasin, a toilet and either a bathtub or shower, or a combination of a bathtub and shower. Homes with two full bathrooms continued to have the largest share of starts followed by homes with three full bathrooms. Homes with four full bathrooms or more and homes with one bathroom or less made up under ten percent of starts each.
In 2025, 63.5% of new single-family homes started had two full bathrooms, down from 65.0% a year earlier. The share of single-family starts with three full bathrooms rose to 23.8%, up from 23.3%. The share of single-family starts with four or more bathrooms increased to 7.8% while the share of homes started with one bathroom or less rose to its highest level since 2012, reaching 4.9%.
Across the U.S., the East South Central division had the highest share at 70.2% of new single-family starts having two full bathrooms, no other division had above a 70% share. The lowest share Census division was the Pacific, with 55.0% of new single-family starts reporting two full bathrooms.
Half-Bathrooms
Most single-family homes started in 2025 had no half-bathrooms at 54.1%. Following closely is the share of new single-family homes with one half-bathroom at 44.4%. New single-family starts with two or more half-bathrooms had a small share of 1.5% in 2025. A half bathroom contains a toilet, bathtub, or shower, but not all facilities to be classified as a full bathroom.
Half-bathrooms are historically more prevalent in the New England Census division as compared to the other eight divisions. In 2025, 66.3% of new single-family homes started in the New England division had at least one half-bathroom. The lowest share occurred in the East South Central division, where only 34.0% of starts had at least one half-bathroom.
