Frosted Glass Shower Door - HELP!

[Ana]

We are having a frosted shower door installed in our bathroom, but I have a question. . . Does the smooth side of the door go on the inside of the shower or the outside?  I say outside, hubby says inside.  What do you say?

[Terri]

Yikes!  My guess is smooth, inside the shower. Remember it is only a guess. Those stupid directions again!

[Ana]

Thank you, Fejes?     The directions say nothing about what side goes where.
