water hose from besement to main floor.

You can use a piece of coat hanger chucked in your drill to fish down between the baseboard and the floor to get the right spot then maybe put in one of those outlet boxes that doesn't need a stud.
Then you could use a cover plate like a cable outlet. Maybe use some JG fittings so you could shut it off and disconnect right at the wall plate.
If that makes sense.
