This complete shower system comes with all required components for full installation, no extra separate parts are needed for regular setup. Users need to fully remove all existing old valve bodies and trims before starting installation, as this system only works with its own included brass rough-in valve and handle, and does not support compatibility with other brand valve assemblies. The 6-inch square rainfall shower head has a 360-degree adjustable connector to help users find the most comfortable spray position for daily showering. The built-in flow restrictor stabilizes water output, and the integrated diverter enables smooth, seamless switching between the tub spout and shower head. The single handle allows easy adjustment of water temperature and flow volume, with 304 stainless steel shower head, solid brass valve, standard 1/2 inch NPT connections and a sleek matte black finish to fit most modern bathroom decor styles.
