Concealed 3-Way Thermostatic Valve Shower Mixer Modern square knobs and a sleek appearance make this easy to install single panel shower mixer a perfect choice. Equipped with a 3-way shower diverter, this brass thermostatic shower valve mixer lets you switch from your handheld shower head or above shower head, to tub filler or body jets any time you wish! A 3-way diverter is typically used for an above shower head, hand held shower head and the third for either a tub filler or body jets. If you only need 2-ways, your plumber can easily cap the third pipe to cancel it out. A thermostatic valve allows you to have separate temperature and pressure controls, allowing you to leave the water on a certain temperature and turn your water on and off separately. Three square knobs from top to bottom: water diverter, temperature control, on/off control Flow pressure: 44 PSI Sleek modern design Single panel design makes it a breeze to install to any surface UPC logo of authenticity etched
