I want to replace the flooring of this bathroom, USA, constructed 1984, off-grade with crawlspace. It once had a leak, and the plywood under it is very soft. The plywood over it now actually covers a hole where someone fell through. The leak is sealed now though.

I wanted some advice on the easiest way to do this. I intend to pull up the tile, cut out the section of plywood (basically the whole room subfloor), then replace it. We're going to pull out the sink/cabinet, and probably intend to replace it since we'll very likely destroy it taking it out.

We're amateurs, so is there anything we should consider? Anything of concern or any advice.
