Yea Haw!
Instead of a space suit, only bathing suit is required?

Yea Haw!It is likely to still be very close to a vacuum but with a thin

smattering of water vapour in it. You would do a bit better in galactic dense molecular clouds of star formation regions where there is water
vapour being excited by newly formed hot stars leading to OH masers.
One of the biggest being W3(OH)

Not as much water in total but a lot nearer to us. It isn't at all surprising that water is fairly common once the initial generation of
heavy fast burning stars have had a go at the original pristine Big Bang
raw materials (which to a very good approximation were ~90%H 10%He4 2ppm He3, 10ppb Li7 (a few other light isotopes at ppb levels) & 0.2ppb D.

D, Li, Be and B play a key part in helping nuclear fusion start in the earliest stars since they will fuse with H more easily than H or He and allows the core to ignite sooner than it would if it were pure H & He.
The CNO cycle in main sequence stars heavy enough to burn helium ensures that there will be plenty of these elements in processed material.
