I am remodeling an existing shower. There is an
existing one-handle shower control. I want to
replace the handle and valve trim with a new one-
handle shower control and trim piece so as to color-
match the new showerhead/arm/flange. The new shower
handle is a different model/manufacturer from the old
one. Q: Do I need to purchase and install a new
rough-in valve also, or will the existing rough-in
valve work with any new one-handle shower control?
BTW, the new one will be a Moen product.
I can't see your situation thru cyber space so I
can't really tell you that you can or can't do it...
Maybe a google search for a matching after-market,
alternative or a search of the manufacture and see if
they do offer a trim and knob upgrade for situations
But from my experiences with LIKE products from
different manufactures, they like to change what they
can change to make it theirs and to stop you from
doing things like this...
I know with automobiles, some models for years will
use the same parts, so when you need to replace
something, you have a span of a couple of years to
choose from, so its possible a search of the
manufacturer of your original mixing valve, might
tell you if they make different colored handles or
Maybe a brass or brushed steel look instead of a
glossy finished chrome look...Good Luck...E.T.
