This is a bit like asking "how deep are the human lips?" Past the lips lie the mouth, and the throat. Past the rectum lies the bowel. The rectum itself is just a narrow sphincter, maybe a quarter of an inch thick. But the bowel is quite extensive. Still, if you are thinking of putting something into the rectum, be careful. You can cause injury if you don't know what you are doing.

The human rectum is about 12 cm long
