or you can go ahead and use a solar bag shower: https://www.amazon.com/Coleman-2000014865-5-Gallon-Solar-Shower/dp/B0009PUT20/ref=sr_1_10?s=sporting-goods&ie=UTF8&qid=1550432756&sr=1-10&keywords=solar+bag+shower

I've tried those, but have had...less-than desirable results. Apparently I lack the sort of coordination needed to use one without peeing all over myself. 😆

So I did the next best thing and created my very own Whiz Palace! It's essentially a large bucket with a toilet seat on top; I secure a small trash bag inside and fill with cedar shavings (like you'd put in a small pet cage), to mitigate any noise or smell. The toilet is then placed inside a pop-up shower tent and voila! I also include toilet paper and other accouterments. I change the bag and cedar daily. It's not pretty, but it beats the heck out of stumbling to a porta-potty at 5am.
