Confused, Our boat has what you folks are calling a 'Wet Head' I guess, as the two, commode and shower share the same space. Our walls are formica, after a shower, a simple wipe down of the walls no more than a minute one would suppose, and check to see that the t/paper remained dry which is the case due to location. No big deal on the
'Slo~Belle', in fact another attribute to our boat when space utilization is in play.
Wifey B: Wet heads work fine for many but given a choice, most would choose dry. I choose separate shower and must be sized for two.
