Why get a separate thermostatic valve? When you have your bathroom reno done, have a new fixture put in that has it built in. I have an American Standard, and the valve works great on it. Depending on access, it's probably easiest to leave that poly B until reno time.
EDIT: Jut realized that is different than a pressure balance, which I have. But it also keeps the temperature steady, if that is what you are going for.
