I have begun to remove the existing bathroom floor. It was 9 x 9 VCT on two layers of 1/4" plywood. The existing subfloor is the strip hardwood, and is slightly water damages around the tub. I susu[ect more serious damage around the toilet and sink area. I would like to put down ceramic tile. Is the only course of action to entirely remove the existing subfloor and start new? Also, do I have to remove the bathtub in order to do so?

In my opinion, yes you will have to remove the old flooring in order to do the job right. If in fact there is water damage on the floor, thenits best to fix it before putting down a new floor. Pull the toilet, and pull the old flooring. Get it down to to original subfloor. Then put down your backerboard.( I like 1/2" hardibacker for bathrooms) and lay down your ceramic tile. The good news is you probably wont have to take out the bathtub, unless the water damage goes under it.
you need to remove all the underlayment so you can inspect the entire subfloor,what is the construction under the sub floor?water damage is usually in corners at the tub,and under the base of the toilet,look them over,call a pro if your not sure.but i doubt you will need to remove the tub.the normal repair would be cut out the bad subfloor and replace with plywood,then nail down the backerboard (1/4") now lay the tile.....good luck
