I was just wondering if anyone has ever put out this kind of product. It involves a control panel in your shower rather than a hot and cold valve. The panel would be able to be used much like a thermostat in your home and would also include a timer, and water pressure. This could also include luxuries such as shower massage and things that can be found on nicer shower heads. This could also work the same way for a bath. I don't really know if something like this has been conjured up yet....
