The impression I get is that they are trying to push boundaries, but they're doing it in a way that smacks of non-consentuality. Its one thing if a couple (or trio or whatever) picks that room because they *do* want the exposure, but its another thing entirely to spring it on people who weren't expecting it. Our frosted glass bathroom wasn't so bad, but take a look at that 2nd link I posted. NOTHING can be done discreetly in there.

The exposed shower idea is kinda sexy, given the right set of circumstances. But toilet? Just no.
