Thanks KURZ!
Not sure I'm up for the plumbing challenge. Maybe placing something like a kiddie pool to catch the water and then carry it out to the cockpit.

I agree with your comment about smart people in this forum. Glad they are willing to share their knowledge with us.
I just got my 2013 26M. I don't have a solution to your heating issue, but I was curious about your shower setup. It the one luxury I crave on my boat. Not a fan of tying up a black bag.
