How to fill holes in subfloor?

We bought a house that the previous owner was in the process of installing a second bathroom. The first bathroom is 5' x 6'. The second is 5' x 5'. I can't figure his reasoning for 2 bathrooms so small, so I'm planning to remove the wall between the rooms and make one 5x11 bathroom. What I need to know is the easiest way to fill the current holes in the subfloor where the 2 toilets and other various holes are.

What is your subflooring material? What type of pipe are you dealing with? Are you going to install a new floor? If so, what material?

Pipe is PVC, most of it never was installed, as I said it was in progress. subfloor is plywood (3/4 maybe), I'm not going to replace it unless I have to.

Cut square holes to the width of the joists, screw 2x4s to either side of the joists inside the hole and screw a piece of plywood down over top of the hole. As long as the holes are not too big, this should be very secure.

Right on the money! Don't forget to cap those pipes too! You can get PVC plugs at the big orange box...

That's pretty simple, I'm actually going to remove all excess pipe when I pipe for the new bathroom layout, thanks for the help!
