Why does the shower curtain float into the shower space and crowd me when I’m taking a hot shower?
In:
Convection currents. The hot water from the shower head is causing hot air to rise and colder air near the floor is moving in to replace it.
The hot water is pooling at the bottom of the tub and the warmer air is getting beneath the curtain as it rises, causing the curtain to float inward.
Solution: get a heavy weighted bath curtain. I got one to replace the thinner-than-paper one from the dollar store and I’ll never go back.
Edit: u/BurnOutBrighter6 has a better answer.
>More that the hot steamy air is rising up out of the shower, sucking cooler air from outside the shower inwards at the bottom.
The hot water is moving through the air releasing steam causing an updraft pulling the base of the curtain in.
Just a guess.
I always assumed it was to do with the change in air pressure, because this happens regardless of the water temperature.
The shower spray causes as area of low pressure, thereby sucking the curtain in towards it.
Scientists aren’t exactly sure. There are a few competing theories out there: https://en.wikipedia.org/wiki/Shower-curtain_effect
