New ceramic tile in bathroom

We have a tiny bathroom in which we want to replace the existing 6x6 ceramic tile with new tile that's all one color. (If you ever wondered how many different and clashing versions of "light blue" can be installed in one bathroom, come and visit our house some time.)
What made our decision to move on this sooner rather than later is that we were re-seating the toilet today with a new wax ring and flange and discovered the wood flooring under the layers of tile and other flooring (vinyl, maybe) was rotten.
We plan to remove the vanity and toilet before this is done, leaving a pretty straightforward job - the bathroom is rectangular except, of course, for the curve of the tub.
We will ask for estimates for removal of the old tile and all other layers of floor down to the wood and replacement of any rotten wood before the new tile goes down.
Question: Will we save ourselves a lot of money pulling up the old floor (down to the wood) ourselves? And is it a pretty routine thing for tile installers to replace rotten subfloor as part of a job?
Any guesses you might have about cost per square foot either way are appreciated.
Thanks,
tmac

Probably not, but it depends on how expensive contractors are where you live. Regardless, having time, strenght and stamina I would do that myself to have a feeling of how much damage is hidden under the floor.

Not really. Some might say it's not their trade.

Not knowing where on earth is Carmen San Diego and what tiles you're going to use? Can't help you there, dear. As you said, ask for a couple of estimates, with and without floor removal and board replacement. Good luck
