The new 2021 shower setup is nice as it give you access to the bathroom from bedroom and hallway. However, it seems the shower is now smaller then the standard 36" x 48" shower. Can anyone confirm this? If so what is the true size?

My dealer said the shower is the same on all M class coaches, but judging by the video and pics I've seen it appears smaller. We are on the fluffy side so going smaller will require more miles around the track.
