The waterproofing is behind the tile in all cases of correct construction. It isn’t the tile. Ever. Theoretically, a correctly built shower could be used without any tile cladding at all.

You can use any subway tile except for ones with a crackled finish, and even those can be used but need to be sealed pror to installation and may crack further. I would steer clear of crackling. The showroom will explain which can and cannot be used. I just put a deposit down on Pratt and Larson subway tiles for the shower walls; they come in myriad colors and finishes, apart from crackled. I was told this yesterday at three different tile showrooms in NYC.

Makes a lot of sense. I wasn’t thinking about the fact that the walls will be waterproofed. Thanks!

Look at the info you posted for the tile. See where it says where it can be used? Does it list “shower walls?” No. There is your answer.
