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?

    Probably not, they’re not usually insulated underneath, to my aging experience. So putting a lid on it wouldn’t keep the other surfaces from leaching away heat

      It doesn’t have to completely prevent heat loss, just long enough for a good part of the day, and of course you’ll refresh the hot water daily haha.

        Right, but I don’t think it’ll buy more than a half hour, it’ll lose that much through the tub itself. Experiment if you can justify it! I’m wrong a lot. I suspect that you’ll be disappointed with the results, though.

    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.
