You will really have to look at it yourself. I suspect the amount of space in the shower and bathroom varies from model to model in the Trailmanor line. Our Trailmanor Elkmont (not one of the foldable models) had a very nice bathroom, but the shower was quite cramped. Tall enough and bright, especially with the skylight, but not a lot of elbow room. Also the shower floor was weak, not well supported, so at 190# I was careful where I stepped.
So I didn't use the shower much. Our new trailer has a much bigger shower with a solid floor and big grey water tank, so we've started using the shower much more.
There's a forum specific to Trailmanors where you can get more info. I found them very helpful with ours.
