We previously had a small traditional fifth wheel with a dry bath - separate shower area. Initially I had a hard time adapting to the idea of the wet bath where, when you use the shower, the whole room including the toilet gets wet. But once we got our trailer, in practice I found that I like the wet bath better. The fiberglass enclosure is bulletproof as far as water, no worries about water getting on things where it could cause damage. The shower curtain just slides over and covers the door opening when showering - the bathroom door is mounted on the outside of that wall and is just for privacy, not water protection.
If you have never used a wet bath, at first it feels weird to have water splashing on the toilet when you shower. But we used to wipe down the shower area with a towel in our old trailer after showering, and it really doesn't take any longer in the wet bath...and the toilet exterior gets rinsed off when you shower so it stays very clean.
