The expansion of indoor plumbing and sanitation in urban homes during the mid-19th century dramatically transformed living conditions in Western cities. The introduction of modern plumbing systems, water supply, and sewage disposal significantly improved hygiene and public health, reducing the spread of diseases associated with poor sanitation. This advancement reflected the growing recognition of the importance of infrastructure in urban planning and public health. The improvements in sanitation and plumbing laid the groundwork for modern urban living standards and continue to influence city development today.

The expansion of indoor plumbing and sanitation in urban homes improved living conditions, influencing realist writers like Henry James and Edith Wharton to depict urban life more vividly. This advancement allowed poets to explore themes of health and societal progress in their works.
