2 is a historic bath house located in southwest Baltimore, Maryland, United States.

It is a small brick building of 40 by 70.5 feet (12.2 by 21.5 m) laid in Flemish bond with black headers and Maryland limestone trimming.

It was constructed in a very simplified form of Renaissance Revival architecture popularized at the turn of the 20th century.

The bath house in the 900 block, Washington Boulevard (U.S. Route 1) in the southwest area of Pigtown / Washington Village, was built for the City of Baltimore by Henry Walters (1848–1931), who contributed four bath houses to the city.

Architect Archer was trained at Princeton University and lived in a landmark townhouse of white marble at the southeast corner of North Charles and West Madison Streets, facing Washington Place and the famous Washington Monument.
