Kohler DTV Touchscreen Shower Controller  Not long ago, taking a
shower involved just turning the knobs on a couple of plumbing
fixtures and waiting for the water to heat up. Now Kohler takes
that simple task to the next level with DTV (Digital
Thermostatic Valve), a waterproof control panel that lets you
dial up the exact temperature of your shower.  The DTV also
links up to Kohler's sophisticated multihead shower systems, its
touchscreen allowing you to individually control pressure and
temperature on up to eight shower heads. Better save up your
money, though, because the controller alone costs $2000, not
including a rather involved installation of all those shower
heads and plumbing hardware. And then you'll have to pay for all
those millions of gallons of hot water.  Kohler DTV - Next-Gen
