Pros and Cons of all-in-one bathroom or separate shower

This is so type dependent that it is almost impossible to answer clearly. We now have a very small A. It has a "Wet Bath". That means it is all in one, but it was designed so well (40+ years ago) that it is both simple and convenient to use. I prefer it to most crampground showers such that if we have FHU it is a Nolo-Contendre. I have also had time in some other "Dry Bath" units that were so tight I could not wash effectively unless I soaped up the walls a spun.
