The first public pool of the US was actually indoors

The very first public pool of the US was opened in the year 1868. This was known as the Cabot Street Bath and was situated in Boston. The history says that there were a number of poor residents in the US that time that did not have bathtubs at their home. So, this was an option for such people residing nearby. Though this was a public pool but as the main concept of the pool was described to be bathing, so it was installed indoors. It is said that Philadelphia is the only place in the US, where there are still no public swimming pools available.
