Pandorum is kinda like that, although the room turns out to be quite big
I quite liked Lifepod when I saw it a long time ago.
It's about a group of 8 people stuck in an escape pod in space after their ship explodes. Apparently it's a remake of Alfred Hitchcock's 1944 Lifeboat. Not a very good one according to IMDB, still it's one of the more enjoyable made for tv b-movies imo.
Cube zero is worth looking for. It was better then Cube 2.
Das Experiment sorta fits your theme, well worth watching.
Unknown sounds interesting, I'm going to look for that one.
