Our shower sets connect to the NPT elbow inside the wall. This is where you'd normally connect a shower arm and a shower head. You can use your existing on-off valve or use any standard valve. Our single-handle shower mixer valve is also now available.
The shower valve mixes hot and cold water and sends it up a pipe to the connector. The water flows through the main shower column to the diverter where you select which shower head you want to use. Water flow is then diverted back up the column to the rain shower head or to the shower hose and handheld wand.
