No, Benjamin Franklin did not invent the bathtub. While he was known for his many inventions and contributions to science, the concept of the bathtub existed long before his time. Bathtubs have been used since ancient civilizations, with evidence of their existence dating back to the Indus Valley civilization around 2500 BC. Franklin is often associated with innovations in plumbing and sanitation, but he did not create the bathtub itself.
