Here’s a gadget for the techie control freak luxury home buyer that is just cool. The Kohler DTV is a touchscreen interface for the shower that controls the temperature and up to 8 shower components. It eliminates the need for multiple valve handles so it really does streamline the look of any shower and comes in a chrome, nickel, or bronze finish. It would typically see installation in a shower with multiple shower heads which is becoming all the rage in luxury homes. The DTV at about $1,000 per controller along with the recently released Kohler Shower Tiles is perhaps just the thing to transform the master bath into a true retreat.
