In my new used building that I'm buying, and putting in a bakery for my wife, there is no bathroom at all. So I'm in the process of installing stud walls and I need to frame a door in. Do I make the stud deminsions exactly 32" for a 32 inch door or do I need to make the door frame a little wider to allow for the thickness of the trim? Say maybe I make the stud opening 33". This would allow 1/2" trim on both sides. Any help would be very much appreciated. Thankyou, thankyou, thankyou. RH in Okla.
