The Alberto concealed thermostatic valve unit provides a single outlet control system. The square controls are perfect to complement modern bathrooms. The shower valve is easily controlled by two handles, one to divert the water flow, one to control water pressure and the other to control temperature. The thermostatic valve ensures that your water temperature remains consistently perfect, just the way you like it. The valve has a sleek chrome finish and made from WRAS approved materials. A minimum wall cavity of 75mm is required for installation of the concealed valve and is designed to work efficiently with a minimum 0.5 bar of water pressure.
