The shower valve & trim are needed to operate your shower or tub/shower system. Please be aware you need both the "brains" (valve) and the trim (handle) to work together to operate your system. In addition, the handle set and the valve MUST be from the same manufacturer. You cannot mix and match based on style or price.
That said, to make things a bit easier, many of the brands offer a Universal valve that will operate all the trims regardless of type of system you are building, but dont want to lie, this can be complicated.
