Very rare that I disagree with Jack and almost a sure fire bet if it is of a technical/mechanical nature I will be wrong. But, opinions and preferences are a horse of a different color.
. I actually prefer using our shower stall if the cg showers are crowded, a ways off, or funky. I do tend to use the hand held feature and do " navy" showers to save water. But, after years of canoe/ kayak trips where cleanliness involved jumping into a cold northern lake or waiting for hours to get the solar shower to heat or transferring water to one after heating it on a backpacking stove------ I find the cramped quarters of the hi- lo positively decadent. Depends on lots of things. But, again, do make sure you have good coverage with the curtains. Like Jack I have two, but some folks have added a third.
