Innovate Building Solutions Our company works with both glass blocks (through our glass block division) and clear glass walls (through our remodeling business) as well. The good thing about the glass blocks is they add more privacy and don't show the water spotting (and they are also available in colored units). The other thing that's nice about the glass blocks is that you can make a curved wall much more cost effectively than curved glass (you'll see a picture below of this).

The advantage of the clear glass is you'll be able to see your tile work and plumbing fixtures better and some people think it's a sleeker look. So the key question is what is more important to you and what do you like better?

I'll include a link to show you some of the new options available on the glass block side:
