BH w/double beds, bath tub, 1.5 baths and U shaped dinette

The "bathtub" is the real challenge. Most seem to be coming with oversize showers. Mine, for instance is a really big shower than a tub (50x30 inches or something). It's huge, but only has a 6" lip for the door (which makes it really convenient for stepping in). But, when dear son (12 months then) needed a bath, we used a fold-up tub container for him.

I'm not sure many new big campers are coming with a tub...
