Doing some research and looking for ideas on non-standard (water-less) toilets. Goal is to eliminate need for blackwater tank. I've seen a few RVs offering this, my thought is there are good reasons they have not replaced standard toilets entirely. What are the pros/cons you guys have experienced?

There is a lot of info around, pro & con. They work, but for most RV owners, a waterless toilet is simply inconvenient and not worth the hassle. And for many of us, dumping waste tanks is not a big deal anyway. Your attitude may differ...

Strictly cost and convenience. Holding tank solutions are simple to construct and operate, and not terribly expensive. "Composting", cassette and other non water based solutions are often more expensive, complex and less convenient to operate. All depends on your goals and if one of the water-less solutions works for you then that's what you go with.

We have a composting toilet for our cabin. It was about a thousand dollars (not sure why). We got it because we won’t have a septic system for a couple of years. It can be messy. I bought the coconut stuff to use it which ended up being a PITA. It comes in brick form and you have to wet it and let it sit for about 24 hours before you use it. I am going to start using peat moss. As far as emptying the toilet that is quite a pain too. There is a urine collector that you just slide out (it has a handle) and you just take it somewhere and dump it (I dug a small pit and filled with gravel). The canister is awkward to dump. The instruction say to put a big garbage bag over it and turn it upside down dumping the contents in the bag. But you shouldn’t put the plastic bag in the compost pile. Anyway, I’m not all that crazy about it.

You shouldn’t be dumping gray water anyway, so if you need a dump for that, why not dump black at the same time? It is actually easy and not a dirty task. I have used composting toilets in wilderness areas, and I am not a fan.

OK, that confirms my suspicions.

We do not have a trailer yet and trying to get some ideas. Was hoping to save some weight and space with the black water tank but looks like it's more trouble than it's worth.

Thanks for the feed back.
