The handle of the cockpit shower installed on my RF246 is made of plastic and is now cracked. Water spews from the crack rather than from the shower head itself.

The unit has never been satisfactory... the hose will not stay on the flimsy hook provided and the on/off valve is sometimes accidentally opened when tending dock lines, etc.
I once saw another Rossy with a neat looking "box" that housed the entire shower assembly. Does anyone have a recommendation for a high quality replacement shower and how difficult is the installation of the upgrade?
Many thanks,
Joy
