I'm sorta like your great granny following you around, Metal Boat. Yes, I do get it that the admiral wants a below decks shower, and our
current boat has one; but, in fact, with a privacy curtain, one can use a sun shower and shower above decks in Qld., and many other places as well. Our old IOR boat did not have a below decks shower, and we sun showered in the
cockpit for 28 yrs....and there was no soap scum and hair to clear from the sump
pump. If you install a shower in the big steelie, if you get it create a separate sump for it, with its own
pump, so that soap scum and hair do not flow to the
bilge. It's way better to pump it to either a
grey water holding tank, or directly
overboard, depending on
regulations where you are. It might be tricky to install it in the 13, it depends on what's already there.
