i wouldnt have enjoyed that close of contact while showering even on my honeymoon. seems you'd always be splashing product on the other person as they were finished rinsing and reaching for their towel. i'd instead work toward zero entry /single showerhead and tag team, instead of showering at the same time.

That size shower is too narrow for comfortable showering for one person so you really only need one head

The new shower will be more than twice the size of our current shower (32x32) so I don't see the overall size being an issue, especially since only one person will be using it most of the time. I'm just trying to figure out if it's possible to have the two shower heads both on the long wall and the entrance on the opposite wall - most likely with a sliding door since it seems I have to give up on the idea of a walk-in.
