A point to note, notwithstanding the existing codes, plaster/gypsum of any kind is not acceptable as a substrate in wet areas as it is food for mold and will create toxic mold cultures in those areas eventually in spite of all you do to prevent it.

Use concrete backer or better yet MgO backer board as it provides no food for mold at all.
