Turn on the turn-of-the-century charm. This thermostat trim kit is part of our traditional Portsmouth® Collection. When installed with a thermostatic mixing valve (sold separately), you select the water temperature with the lever handle and operate the on/off volume control with the cross handle. Once set, the temperature remains constant.
Old World charm and traditional craftsmanship radiate throughout the water efficient Portsmouth bathroom collection from American Standard®. To achieve its turn-of-the-century authenticity, each design facet - from the symbolic Portsmouth cross handle to the vintage spout detail - has been carefully crafted to reflect an intricate and iconic period piece.
