Yes! The drywall board in the bathroom is green.This is a special type of drywall board which is mildew- and mold- resistant. It isn't that much more expensive and I can't think of a better way to ensure that the bathroom doesn't become a source of illness.
This is particularly important for cottages and many different guests means different styles of bathroom use. While you might always put the exhaust fan on, perhaps not everyone remembers. Moisture means mildew and other nasties.
