IIT Madras hostel facilities are the same for students of all degree programs. M.Tech, MS, or Ph.D. students don’t get any different facilities.
The hostels have a sports room with carom, TT, etc. Badminton court and other sports facilities are also available inside the hostel premises.
The hostel facilities are the same for B.Tech and PG students.
Hope this gives you an idea about the hostel facilities at IIT Madras.
