In my basement, there is a toilet installed with an odd thing about 3 feet away from it, to its left. Basically, an opening of some sort is on the floor, raised about 1-2in., with a rubber cap tightened on it.

Does anyone have an idea as to what this is? I was wondering if it was an old drain considering its proximity to the toilet.

Many thanks for any assistance!

A cleanout perhaps?

It might be a rough in for a shower or tub or something. What is the diameter of it?

As ACD says its most likely a cleanout. Most codes require cleanouts to be 2" above the floor so people don't install a toilet on them. If its in a walkway though, you are allowed to cut them down and install an evertight type flush cleanout plug in it.
Good Luck

The diameter is about 1.5-2 inches. I thought clean-outs were larger in diameter and located near the main waste stack? This opening is in a separate area from the main and secondary wastes (a good 20+ feet).

Thanks for all the support.

Heh! raymondvinzant, having just read your earlier note, I think I just saw a toilette yesterday that was installed on top of a cleanout. It's in the basement, and sits atop a plywood platform that's a couple feet off the floor. It's in a very old house. I thought it rather odd, but now I wonder if the guy didn't just mount it on the cleanout as you say.

I would say that it is a stub for some plumbing fixture that was never installed. Perhaps someone had grand plans to put a sink, tub or laundry setup near there. The pipe sticks above the floor so the rest of the plumbing system can latch on to it. Unless it is in your way I would just leave it there with a plug in it.

After reading your question again and thinking about it, its most likely the vent for the toilet that was never connected. Every fixture in you home has a vent that diverts the sewer gasses up to the roof. Many homes, when built, have fixtures roughed in the basement for future expansion. Typically the piping is capped off above the floor. Often times someone else comes in and installs the bathroom after the home is sold. Many handy men use the opening to drain other fixtures into it, without realizing what its for. And many times I find the pipe has never been connected into the vent system for the home. In 30 years of doing plumbing, Ive run across this many times. This is only a guess.
Good Luck
