Bathroom Materials - Where Do You Begin?

The decision is made and it's time to renovate that outdated bathroom, which is in need of desperate repair.  Given the size of the space, how hard could it be?  Really, all that's needed is a vanity, tub and/or shower fixtures, a toilet, and some pretty tile to create a tranquil space.

Or, so it seems until the process begins.
