Transform your shower without a full remodel using the Kohler HydroRail 3-in-1 Multifunction Showerhead and Column Kit. Designed as a simple retrofit solution, this system upgrades a standard wall-mounted shower into a sleek, modern column shower with multiple spray functions and adjustable height control.
The HydroRail column provides a vertical mounting system that supports both the showerhead and an adjustable bracket for optional handshower use (handshower sold separately). Its durable stainless-steel construction offers a contemporary look that enhances any bathroom style.
The included multifunction showerhead delivers a customizable showering experience with six spray settings, ranging from full coverage to powerful massaging streams. Kohler’s advanced spray technology maintains strong water pressure while ensuring even, comfortable coverage.
Installation is designed to be easy—no need to alter existing plumbing or break into the wall. The system mounts directly to your current shower arm and water supply, making it an ideal upgrade for homeowners wanting a luxurious shower experience with minimal effort.
