Going to depend on what Jacuzzi you have. The YJ will require an energizer kit to make it possible to install Berkeley droop and diverter. For the WJ you have a couple options... You can get an off the shelf Place Diverter to fit without special adapters but no droops are available that I know of. The alternative would be to use an adapter ring between the WJ bowl that changes the bolt pattern to the Berkeley pattern, making it possible to install a Berk droop and diverter.
