HydroRail allows you to easily upgrade a standard fixed showerhead to a spa-like showering experience with luxurious showerhead and handshower functionality. It's designed to accommodate a wide array of shower configurations without altering in-wall plumbing, making it suitable for both remodels and new construction.

For smooth toggling between handshower and showerhead functions, this column features a diverter conveniently located at the base of the column.
