Also, can you waterproof drywall? Yes, you can make drywall pretty much waterproof if you coat it on all sides and edges with water-based urethane before you install it.

Can you use regular drywall in a bathroom?
You can hang drywall in the bathroom but not the same type that you hang in the rest of the house.

It isn't appropriate for areas that actually get wet, however, such as shower and tub surrounds.
