(unless it fits between a pair of joists)

You would have to lose a bedroom if you installed your laundry room
upstairs, so a chute would be a good idea. As it is only laundry, the
space between joists should be enough, shouldn't it?

The dumb waiter is a good idea as it allows travel in both directions.
