Still trying to configure a shower in the head too. The problem as stated is an adaquate drainage system. So far the only thing I've thought of that may work is a deep shower pan fitted to the lower portion of the head with a bilge pump sharing room with your feet. A curtain would have to be attached to it as well. As pointed out real tight. Perhaps the curtain could be arrainged to allow sitting on the toilet. Maybe it would be easier to place one in the cabin. For now the solar shower works well. Also bought a Zodi shower unit at e-bay for $55. The Zodi is an instantaineous propane fired water heater with a small pump designed to be placed in a container of fresh water. It will also take water from a hose or presurized water system. There is plenty of space to secure 5 gal jugs of water. If you are at an anchorage, 5 gal jugs may be the only means of getting fresh water aboard anyway. alan
