Welcome to the forum. Sorry I can't really help you with your question. I have a rear engine, so my bedroom is going in the back, and the shower and toilet are just in front of the rear axle. And if I had a front engine I would want storage in the back, accessible from either outside through the rear door, or from the inside through a door in a wall that would prevent things from falling or sliding forward during a braking incident.
In my opinion, storage in the back is the only reason for having a front engine, but there are diverse opinions on this site, and I am confident someone will have some suggestions for you.
