This product will only need hot and cold water lines coming into your bathroom and they hook directly to this unit. You can only use two features at the same time. You will not be able to use all three functions together. This product has a Thermostatic mixer that allows you to control the temperature of the water and also a 3 way diverter/volume control that will allow you to switch functions and control the water flow coming out of each function.
I have now been with the company 4 years, I know which fixture works best for your lifestyle. In addition to this knowledge, I’m a woodsman, hunter, and overall outdoorsman.
