When I went to take mine out I had to cut it in half. Before doing anything drastic are you sure there's no way you can excess the plumbing from the other side of the wall? Its a lot easier to patch drywall than pull a tub. The faucet and pipes should be attached to the studs in the wall and not really attached to your tub. I don't really know what part of your faucet is leaking.. Some parts you should be able to excess from the front without pulling your tub. If its from the down spout you could probably loosen a screw or allen head that's on the bottom pull it off replace it or replace the O'ring inside. I hope I have help out.
