So assuming they are... I'm still stuck at "why is this a thing?" Why do we need magicchange glass when particle board is far cheaper? I would have to be in dire straits to use one of these as my bowels would freeze up for fear of the glass switching to clear when someone jiggles the handle
There's a lot of things that people do that aren't for practical reasons. That's why all our homes aren't just concrete cubes. Somebody must have decided that this looks cool and futuristic.
Strictly from practical reasons, I suppose it's marginally easier and faster to identify a free stall. Whether that is worth the extra cost is subjective.
Also, the default state for this glass is frosted. In case of a failure it all becomes frosted.
Maybe, but you'd have to wash shitstains even off regular opaque stall walls. In fact, I can see how it would be easier to do with glass walls, as glass isn't porous, unlike the usual materials that are used for this purpose.
