Glass that is frosted is said to be "depolished" in French. The smooth surface of the glass has been "roughed up" so that the glass is no longer clear. The Robert dictionary gives this meaning of the espression « verre dépoli » — « verre qui laisse passer la lumière, mais non les images. Le verre dépoli peut encore être qualifié de " translucide " mais plus de " transparent ". »
For our new shower, we decided to have the glass shower enclosure panel that faces the door into the room made of verre dépoli. That way, the shower is less "in your face" when you look into the bathroom through the doorway. One reason for that is that we don't generally keep any interior doors closed in our house.
Here's what the shower looks like from inside the bathroom. As far as the color of the tile goes, well... it changes all the time. It's a little like my Citroën C4 automobile, if you remember my photos of that. I bought it nearly two years ago, and we had a discussion on the blog about what color it really was. Mauve? Taupe? Gray? It's all of those.
Sorry if the photos here are blurry. It's probably not too smart to be trying to take photos before dawn and without using a flash, for fear of getting blinding reflections in the tile and glass.
