Most cruise cabins and their bathrooms are small and have limited counter and sink space. But there is a cheap and easy solution for keeping your things in place.
Get an over the door organizer and hang it over the bathroom door or shower rod.
These organizers are intended to maximize space in a pantry, but you can use it to do the same thing with your cruise bathroom.
There are lots of clear pockets, so you can keep all of your toiletries and other important items in close reach without cluttering the counters and shelves.
