Like, if you can trap the heat in could it at least keep the water comfortably hot for an extended period of time, like say 8-16 hours?

    I don’t think most bathtubs are insulated on the sides/bottom. At least not older styles.

    Any heat that you trapped at the top would escape out the sides/bottom after a lot shorter amount of time than even 8 hours.
