The Kohler K-T101111-4-BN, in the Vibrant Brushed Nickel finish, Antique volume control valve trim is used with custom showers using separate volume control and temperature control. This single handle provides precise control of the volume of water and the on/off settings of the water.
This must be paired with a temperature control valve and trim that will control the temperature of the water before the water flows through the volume control valve. Both valves are needed and depending on the number of showerheads and/or bodysprays being used, you may need more than one volume control valve and trim.
This is from the Kohler Antique series and matches the rest of the Antique line of faucets and accessories, and the lever handle makes this ADA Accessible. For more information or to purchase this item see here.
This includes the Kohler patented K-Joint installation technology allowing for consistent install and appearance (fitting in place in the wall) regardless of the variance in valve installation.
