No, the IIT BHU hostels do not have attached washrooms. Even the rooms are shared, and you won’t get a single seater room facility over here. Most government colleges do not provide their students with premium facilities. IIT BHU is one of them.
Thus, IIT BHU only offers common washrooms to its students in the hostels.
No, there are no bathrooms attached to hostel rooms in IIT BHU. In fact, that is the case with most of the IITs. However, there are enough facilities available for the students in each hostel. Most of the hostels in IIT BHU have one bathroom per 10 students and that is more than sufficient in terms of availability. And most of the time students don’t face any problems regarding the bathroom facilities. In a few hostels like Limbdi, Rajputana, and Vishvesvaraya that there are washbasins in the lobby and they’re each per 10 people too. So, that pretty much sums up the bathroom facilities at IIT BHU.
