I actually just did this on my 2017 AR240
@Adrian Jimenez and it came out nice and worked perfect for my needs.
My 2011 242LS had the factory shower which we used but the spray was weak and the hose was short.
Enter Google searches....and I stumbled on the spraybox. I found a 6 gal tank and they added their parts and I now have a fully integrated fresh water (reverse osmosis, dries spot free) shower with 100psi and a 25 ft hose with a multi spray nozzle. It works flwlessly... my installer put in a nice switch and I used it this past weekend to mist people down, clean the grill and hose down the entire boat after I pulled it out before I wiped it down.
I still have at least 4 gal left and if you wanted to have a larger tank no problem..this is plug and play...I toyed with buying the parts for the stock shower but it's like 1k and doesn't do what I need.
I mounted mine where most people board or enter, but I can still reach the bow no problem.
