3.3.5 (NFPA 13, 2007) allows up to a 36 inch wide opening without a lintel. Provided there are no other openings to adjoining spaces. The same allowance applies for small rooms (3.3.15). The only definition you meet is bathroom, however, with the wider door and no lintel I would say it needs a sprinkler. Wouldn't the 8 inch lintel serve as a means to prevent/delay fire/smoke spread across the ceiling? Being the door is not self closing there is a chance that it could be open during the fire allowing the spread of fire/smoke across the ceiling. If the door were self closing it may be acceptable to an AHJ to not have the room be protected.
