Kohler K-T950-4-SN Stillness Rite-Temp Valve Trim with Lever Handle - Polished Nickel (Pictured in Brushed Nickel)

Stillness Rite-Temp maintains desired water temperature +/-3 degrees Fahrenheit so you're always perfectly comfortable. Drawing its inspiration from the pure, sleek geometry of Minimalism, Stillness is as much artistic as it is functional. The diaphragm design eliminates freeze-ups from contamination and hard water.
