Not functional. Beautiful piece of hardware, and it arrived well packaged. However. the second we turned the main water line on the shower fixture shot water out of every joint (except the shower head). It’s also a non-standard installation that has separate valves for hot and cold water, making it trickier to measure for install. Also not functional with standard diverter if you are trying to install in a bath tub, not shower only. Trying to figure out how to get refunded.
