Mmmmmmh, about the shower room….maybe it's more easy to have a full bathroom then a simple shower.
I mean, a shower room can be a shower box or a not so big room, not pretty good for AChat purpouse. A bathroom can have a shower on a wall where dev team can place all the at the wall poses and others i don't have in mind now and for the bed, well, we can use a jakuzi: closed for bed scene (some can be closed, i had post a pic of them long time ago!) and open for the “Let's talk” pose.
I think this is the only chance to have it a good shower room
