I have a partially finished basement bathroom with a 1.5" drain line stubbed out underneath the surface level on the concrete floor. All the work from there is done, goes into an ejector pump that the current working sink and toilet use. I was thinking, installing the shower will be easy but then I realized that the drain is not centered at all. I have thought my only option would be to have a base built from scratch to line up with the drain, but is there another option for this, like a slightly raised base with enough room to reach the drain?

Most prefab shower bases have the drain slightly recessed below the concrete floor. This is why a shower rough-in should leave a 12x12 area with no concrete around the drain. This also allows the position of the drain to be moved a bit as needed when the base is installed.

I would cut 12-18" of concrete out around the drain and dig the trap out so it can be moved.

If you are in the USA, I would question the installation further, as a shower drain and any pipe under grade is required to be a minimum of 2" pipe.

There definitely isn't 12" around it, but perhaps 8-10", I will check the size again since it may be 2" maybe I am wrong there. Thank you the reply though I will get a pic also

Hey, wait a minute.

This is awkward, but...
