The googled page shows something that costs over $300. However, it seems
close in function to a cheaper Delta valve I have. The controller thingy
in it was worn out/kaput, when our plumber diagnosed the problem. It was
replaced and now all is well again. Cost waqs considerable, but by far not
$300 plus labor. Our symptoms were diminished flow, irregular temperature
control (although when set, the temp stayed as set - just that the handle
for the temp setting was different from time to time).
I suggest getting a plumber to take a look at your valve before you open
If this is to me (Han), the Delta faucet I have has a diverter for the
shower (you push it in, and then the water goes to the shower rather than
the bath faucet). It has 2 handles, one for water on/off with a bit of
volume regulation, one for the temperature.
I was just trying to say that ther might be no need for doug to break the
wall open. The innards of such a faucet are completely accessible
through the front (if his faucet is like mine and the one I googled).

The problem was mineral build up in the lines!
All I did was pour CLR down the shower pipe every 30 minutes for 3
That clean up both the shower line and the tub line.
Kohler has outstanding customer service. Over the years they have
patiently helped me with a number of small problems, occasionally with
free parts. Look up their number and give them a call (sorry I don't
have it handy). If you don't have literature for the product, get that
first to review installation directions and have part numbers handy
should you need them. Good luck.
