See the below link video. He has done the main thing right - sofa/bed lengthwise not across width which would block access to rear. Bathroom although very small just might work for you. The one key thing that would make it much better is a swiveling front passenger seat, however at present no one sells a swivel for the odyssey ;-((.

The floor space in the back is 4'x8' - so unless you are under 4' tall, a bed 'across' the back won't work. The setup above or something similar is what you need to do.

Good question, I should have explained further. A sofa/bed oriented side to side (or across the back) is typ designed for sleeping front to back after the sofa is extended/unfolded to bed mode. This version blocks access to rear of van. The most popular/referenced build of this type is described by Eric Enjoys Earth on YouTube at:

The version with bath in my previous post has sofa/bed front to back, which when made flat is also for sleeping front to back, and allows rear access when in sofa mode.
