That looks like it but it looks too close to the wall for a toilet to mount directly over it unless the wood wall? to the left is removed.

Now you have to figure out how to run your new plumbing since the clean out is above the existing floor level. You can build a raised floor for your new bathroom so you have somewhere to run the plumbing or you break up the concrete and run the plumbing under ground.

Yes, you can add a pump but that will require a raised floor or platform since the plumbing needs to be below the bottom of the shower, and you still have to consider the toilet. Most toilets require the drain line to be 12" away from the wall, though there are some (usually more expensive) that have their drain connection closer to the wall. The least expensive and best option is probably to break out the concrete.

I'd start watching the Sunday morning home improvement shows. Quite often they are doing something similar.

First, I'd measure your space and draw out a floor plan. Go to home improvement stores and look at the fixtures (shower, toilet, sink...) that you want. Note their dimensions (will it fit through the door to get into your basement) and the hook-up locations. Draw the fixtures on your plan. You may be able to change your plan to minimize the amount of plumbing under the floor.

If you are doing a shower/tub, sink and toilet you will need a vent. Check with your local codes. You might be able to use a Studor vent for the sink & shower.

I don't think you can raise the floor at that point, from your picture it looks like you would have to raise it at least a foot, I don't think you have that much extra room in a average basement.

If this is your first plumbing project, I wouldn't recommend breaking up concrete and tapping into cast iron drain pipes to be your first project. It's all doable, but not an easy project.

If you do decide to go down this path, get a couple books to understand how to setup shower/toilet drains and venting requirements. They are typically pretty standard, though some locales have special requirements.
