Yes. The whole shower is glass. The door to the shower is glass. The door to the bathroom is glass. The floor and ceiling are not glass - see below. (Shots are from my 1 night stay in April 2016 that I'm still trying to turn into a review).

Side view of bathroom door - shows an oblique view of the bathroom door plus the sliding rail for the door on the right side of the image (also shows the entryway from the room's front/entry door):

Back view of the shower from inside the room:



Inside view of the shower from the middle of the bathroom:



Steel support/sliding rod for the glass shower door - note what's glass, what's marble (ceiling neither) but shower head is a rainfall:



View out of top of shower wall - anyone over 6 foot tall can see through the non-frosted portion and into the room and obviously out the window:



Marble floor of the shower (note that the parts of the bathroom that are not glass are marble):



Just to prove that we got lots of glass, here's a view of the bathroom at night from the bedroom with the bathroom lights turned on:



As well as a shot of the closed bathroom door at night to show its true glassy nature:
