Ep. 64 | What Are Your RV Toilet Options?

We just returned from our two week trip using the newly installed Seperette, cost $160. We have a class A motorhome and always disliked the standard toilet for a few reasons. The direct hole to the black tank when flushing, the water waste when flushing and knowing there was a tank of crap and urine we were dragging around with us until we found a dump station. I built the very simple box for the Seperette seat product and saw dust compartment. The Seperette simply seperates the urine as a compost toilet does. You supply a 5 gallon bucket for poop and a container for urine, a gallon jug usually. I was able to find a rubber cap for the 3 inch black tank opening and cut a hole in it the size of the included hose for the urine. I didn’t want to deal with the urine bottle, because I heard that stinks much worse after a couple of days than poop. So the hose for urine drains into the black tank which I now share with the gray tank, almost doubling my gray water storage. The urine mixes with gray water, by the way urine is sterile, and that gray water is actually safe to drain in into the environment. Just be cool and use biodegradable soaps for washing yourself and dishes. The poop simply goes into the bucket lined with a plastic bag. You put sawdust, peat moss or coconut husks in the bottom of the new bag and on top of poop. I drilled a 2 inch hole in the floor for a small computer fan which vents consistently and draws a very minor amount if power and cost less than 2 dollars. When the poop bag is full it is leagel and safe to simply toss in any trash can. The smell that does exist post pooping is venting out and once poop dries the odor diminishes almost to nothing anyway. The urine hose in my set up naturally forms a “P” trap which eliminates any smell coming from the tanks, we all know gray water still stinks. After urinating we spray a few spritzes of 50/50 mixture of vinegar and water in the urine area of the Seperette to neutralise the urine odor from the trap. I don’t need to visit a stinky dump station ever because my gray water and urine is actually bennificial to plants so I drain it in a convenient spot when I find one. I now have 100 gallons of waste water storage and use much less due to no flushing. We experienced zero smell from the bucket or the p trap urine tube on our two week trip. We don’t have remove anything other than a plastic bag of poop and sawdust from the rv, poop not even visible through a clear bag . We don’t have to clean the toilet as with expensive compost or cassette toilets. We save water, nurish the planet with our gray water, save dump station money, eliminate the need for sewer trucks running around transporting waste to another facility to process it and…I’ll never go back.
