As to a curtain - we used hooks and a long metal curtain rod to put a "brown suede shower curtain" across the middle of the hallway of our travel trailer.
Makes it nice when taking a shower as the bath and bedroom are at the end of the hallway, that way we can shower and dress with privacy.
The shower curtain is washable as long as we use a Laundromat with front opening washers, and it dries nicely in a dryer if we don't let it completely dry, and then bring it home to hang up and finish drying.
We have used it for 8 years and it still looks almost new. AND bonus is that it can be taken down if we ever decide to sell or we no longer feel the need of it.
PS: and used a cup hook to put a drapery-cord thingee to wrap around the "curtain" and pull it back out of the way when not drawn across the hallway.
