My glass enclosed shower works fine.
When growing up in more humble surroundings my shower curtain at one time was unreasonably attracted to me so I cut some upright slits in the lower portion, still within the tub, and found it to be better able to restrain itself.

As to space and the universe. I can not conceive
of a limit to either. A handicap of mine which I have never been able to overcome. Cheers.
