1. Plumb studs
2. Wall thickness consistent
3. Flat straight walls
4. Square corners

All are very important. A vanity (or similar cabinet) for example,
installed on a crooked wall will have a nasty obvious gap at the back
splash. A shower module or or tub shower enclosure will be a disaster
to install in anything not square, plumb, or level. Even the flooring
will be a PITA trying to get decent lines, and setting tile will be a
nightmare of mismatched hard to cut bits and pieces. Considering some
of the decent prices on lasers and such from Stanley (the Fat Max
line) now, there's no excuse for not doing it right.
And do yourself a favor, use the new non paper-faced wallboard and
take advantage of it's compatibility with the bathroom environment.
Every hour you 'save' taking shortcuts or skimping on the job will
cost you double, triple or more trying to make things work. Good luck.
