The indoor plumbing revolution of the mid-19thcentury quickly led to the modern bathroom.

The bathroom and the kitchen are the two rooms in the home that change most often. There are a variety of reasons for this including newer technologies, changing architectural fashions, and rapidly evolving appliances and fixtures. The bathroom has a particularly important story in this evolution of urban sanitation and the modern home. The popularity of the “three fixture bathroom” with the toilet, sink, and bathtub is a product of the 19th century and the “indoor plumbing” revolution. The development of modern urban sewer and water systems in the mid-`19thcentury was rapidly followed by the interior architectural evolution of the bathroom. For farm households, the plumbing catalogs included the water supply and septic systems, which are still a part of rural settings today.

​The Building Technology Heritage Library has a large number of plumbing fixture catalogs as the core of its materials about the bathroom. The larger plumbing catalogs will have hundreds of pages with details of piping, fittingsand the myriad of basic components to a completed plumbing system. The 19th century catalogs mostly tell the story of plumbing parts. In the early 20th century the “bathroom” as a complete set of plumbing fixtures and a room layout become the common form of marking for residential buildings. The earliest bathroom catalogs featured the most basic of plumbing fixtures, sinks, toiletsand bathtubs. The later bathroom catalogs often feature the entire room layout with notes about architectural finishes and casework. Additional fixtures such as a sitz bath or foot bath could be added to the room. Bathroom accessories such as medicine cabinets, towel racks and tissue holders are yet another category of bathroom products.

​Plumbing catalogs vary considerably depending upon their focus on the commercial or residential properties. The examples selected for this article mostly cover the residential bathroom. One noteworthy part of the story is the evolution of colored bathroom fixtures, which started in the 1920s and continues today. The Kohler Company introduced their first line of colored plumbing fixtures in 1928, in a catalog entitled “Color charm enters the bathroom.” The Standard Plumbing Company quickly followed this trend with even bolder fixture colors. By the 1950s the pink bathroom was available from most plumbing fixture companies. There are several interesting bathroom catalogs from the mid-20th century that promotedcolor choices for both the fixtures and the room décor. Whatever the era of your house, the bathroom designs through the ages found in the APT Building Technology Heritage Library can educate and inspire.
