They use an incredible number of off the shelf shower grab bars I recognize from Home Depot in the interior of pretty much every ship. I find things like that a bit distracting.
Maybe when it comes to something as simple as a grab bar it's hard to get too imaginative in the first place?
Once you start _really_ looking for them, you can pretty easily pick out items on a set and go, "oh yeah, that looks like a repurposed so-and-so."
