I get compliments all the time on this, and I don't know why more people don't put these in their bathrooms.  They save a ton of room and lots of money.  I have a 6.5 x 8.5 bathroom which is about the size of some peoples' shower stalls, so the issue of the shower being drafty without a complete enclosure is a complete nonstarter.  It's plenty warm and steamy.  It frees up a lot of floor space and it makes it a dream to just walk into the shower.  TIP:  consider moving the handle of the water.  I did a complete bathroom makeover so I had no issues installing the handle on the opposite wall of the shower head.  That way I don't get a spray of freezing water on my arm when I turn on the water to take a shower.  I think it looks really, really nice and it does the job so well.  The glass is pretty darn thick and heavy.  It's a two-person job to set this thing up properly.
