Key features

• Trim only: decorative square trim kit with knobs and thermo cartridge; requires separate VALVE690 1/2" thermostatic rough-in valve for installation. 
• Thermostatic control: integrated thermo control cartridge maintains a set outlet temperature to help prevent sudden temperature changes. 
• Progressive volume control: volume knob allows you to gradually increase or decrease water flow independent of temperature for personalized comfort. 
• Independent temperature control: dedicated temperature adjustment lets you dial in and maintain your preferred shower setting.

• Square, contemporary design: sharp lines and square backplate coordinate seamlessly with Corsini, Gattinara, and Scala fixtures.
