can I install 12x12 ceramic floor tile on my bathroom walls and shower walls?

Hi, eddyepp!

Around where I'm located, I've seen it used in those ways successfully.

Are you wondering if there might be some sort of code restriction for where you're thinking about it being used, please?

Thanks!

No problem, what made you think this might not be OK?

Probably heard it from a big box employee. They are always telling me I can't do something!
