Kohler K-28209 Anthem® Two-Port Digital Thermostatic Valve
Precise Digital Temperature & Flow Control for Kohler Anthem Shower Systems
The Kohler K-28209 is a two-port digital thermostatic valve engineered for precise temperature and flow control in Kohler Anthem shower systems. With two independently controllable outlet ports, it suits one- or two-outlet shower configurations while maintaining consistent performance through digital thermostatic technology.
Built with a reinforced engineering-grade thermoplastic body, the K-28209 fits within a standard 2" × 4" wall and uses a plug-and-play connection for compatible Anthem digital controls. A built-in eco mode limits operation to one outlet at a time, and a selectable low-flow mode supports water-conservation or CEC-compliant installations.
Important: This valve requires a compatible Kohler Anthem digital control and a 120V GFCI receptacle, both sold separately.

The K-28209 is the right choice for homeowners and contractors building a Kohler Anthem digital shower system with one or two outlets who need precise digital thermostatic control, antiscald protection, and a clean plug-and-play installation.
