ᐅ Walk-in shower: drywall construction or masonry, alternatively glass partition

We’re having some trouble with the walk-in shower in our main bathroom. We had planned to have the shower wall built up about 1.30 m (4 feet 3 inches) high, with glass extending from the top of the wall to the ceiling. Our contractor misunderstood a bit or had forgotten about the glass panel at the upper section. He assumed it would be drywall, but now he says drywall with glass on top wouldn’t work because it wouldn’t be stable enough—the wall would be standing freestanding in the middle of the room. As an alternative, he’s suggesting a full glass shower wall.

We’re not really happy with that option. Does anyone have experience with a built-up shower wall with glass above? Or with drywall and glass—does that work and is it stable?

Also, does anyone have examples of stylish glass shower walls? Maybe that’s the best solution since it takes up the least space. We haven’t yet found the right design though; the tiles will be a rust color, so the shower wall needs to match and have something a bit special.

It would be great if someone could share photos of examples. We need to decide next week. Thanks to everyone who takes the time to think about this!
