The Townsend thermostatic valve trim kit from American Standard offers a central location in the shower to control temperature, for the perfect temperature shower, and the thermostatic mixing valve (sold separately) will keep it constant. Your shower system will also require a separate On/Off Volume Control with trim. With design elements inspired by the Manhattan bridge, the Townsend thermostat trim kit is both functional and stately. Available in four stand-out finishes, and expertly coordinated with the rest of the Townsend collection, the thermostatic shower trim kit is an easy upgrade for your bathroom.
