For a simple and quick solution to our potty situation, my hubby built something close to an outhouse. It has two walls, and the back and front are covered by shower curtains for light and privacy. The top lifts to give access to the buckets and supplies for easy cleaning as well as easy storage. We use pet shaving litter for our solids bucket and vinegar and water for our liquid section. We purchased a large plastic food storage bowl and a funnel. My hubby came up with the design and used super clue and then caulked them together for extra security and to make it leak proof. You will see it installed in the pictures below. Quick and easy urine diverter!
