It's a problem all RVers have to deal with: Where to put the dirty laundry until wash day rolls around. If someone could come up with a 'one size fits all solution' they could really clean up. Meantime, here's a laundry list of possible solutions:
Put the laundry basket in the shower stall--take it out when it's shower time. Great, unless the cat's litter box already occupies the space.
As an alternative, hang the dirty laundry from either a retractable clothes line, or an additional shower curtain rod, hung in the shower stall. Keeps the cat happy.
Get a hanging laundry bag. We've seen a couple of different inspirations on this idea. One hangs on a closet road like a coat hanger; the other hangs over the back of a door.
Motorhome or trailer owners with plenty of basement storage may find an idea here: Cut a trap door in the bottom of an existing cabinet, then place a laundry basket in the basement compartment immediately under the door. Pop open the door, drop dirty clothes in and forget about them until wash day.
One couple put a laundry bag in an under-counter cabinet, but found they were to lazy to pick up the bag to put the clothes in it. As a result, the clothes just wound up being piled on top of the bag--making a big hassle on laundry day. Solution? They put grommets on the rim of the laundry bag and hung them on cup hooks placed under the countertop, leaving the "front" of the bag gaping open, ready to accept dirty donations.
More inconvenient, but if there's no other place: Put the laundry basket in your pickup canopy, or the trunk of your towed car.
