There are too many considerations to handle here. I recommend a basic plumbing book Should be available at your Home Depot or hardware store, probably also at your local library.

Your two considerations are supply (hot and cold water incoming) and DWV (drain-waste-vent). Incoming is easy, you just have to cut water to your house, cut into the supply lines, attach branches, turn the water on and heck for leaks. How you cut in depends upon the type of plumbing materials.

DWV is more problematic. You have to have a trap to hold some water in the drain. This keeps sewer gasses from coming back into your house. For it to work right, you have to have a vent to your roof. You can tie into an existing vent, which is the easiest and most affordable, but your drain can't be farther than a set distance from the vent stack. The drain line has to be slopped towards the vent, and the rate of slope is fixed, so the distance varies with the diameter of the drain line.

You could call a plumber for an estimate. If the water lines are "stubbed out" and the drain line is present but capped off and these are easily accessed, the price might not be too bad. But if he has to add the vent and/or a drain line, it will get expensive.

Suggest you check out the books first to see if your up to it, but a plumber would probably not charge for the estimate.
