Is there a lid you can buy for your bathtub so you can make it into a short-term hot tub during the day?

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.

What you’re looking for is a eastern European/siberian banya style tub setup… And no that’s not just a lid. You need lots of insulation and insulting interfaces between spouts and pipes. Even then those only stay hot for like 3-4 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.
