This is a really hard subject. We all know that acoustically treated large rooms sound great. Drums need the space. However, much of the drum sound you hear on modern metal records comes from the close mics. I have recorded drums in very small and low rooms and have still gotten great results. If you are going to book a studio, make sure the drum room is decent sized and not completely dead sounding. It will be very hard to get a "live" drum sound without any reflections from the room. It will also make the drummer tend to hit the cymbals too hard. Trust me, you don't want that! If you are using a completely untreated room, add some furniture, blankets and mattresses. Just don't make it too dead sounding in the high end.
