I just installed a quick set up shower stall into my Venture 222, when the pop-top is up and in place! My base is a modified container, that I attached an auto windhield washer pump to, which carries the water away and keeps the base just about empty of water! I simply clip the pump to a quick start jumper battery for cars, and flip the on off switch and away it goes! I can direct the water into my porta potty tank for a recycling of the H20, or to some other destination! this certainly will increase stay aboard time and for a little boat, I have all the luxuries of the biggies now!!!!!!!!!!!!!!!!!!!!!
