Camp Toilets

Portable Camp Toilet - This is the cheapest of the cheap. It's a toilet seat with a trash bag under it. It's obviously also probably the easiest to carry around - but the downside is that there's nothing between you and that smell. It's going to be functional, but if you can afford to splurge this might be the piece of camping equipment to do it on. This one is about $16 and available online here.

Sanitation Equipment Deluxe Portable Camp Toilets- This is going to be a much better experience - it weighs ten pounds, but it is not as easy to carry around for any distance because of the bulk and because you put water into it so that you can flush it. The water will make it a lot heavier. It is, however, much closer to a real toilet than the cheap version. It's got a holding tank for the waste and a spout to allow you to dispose of it easily. It is a little expensive though, at about $115 - you can get it online here. 

Coleman Camping Toilet - It's another more advanced one, but not quite as expensive. It's also ten pounds, and a little easier to carry both because it's got a handle and because it doesn't hold as much water. It's also got the flush feature as well. It costs about $80 and is available online here.

Boom Box Toilet - This one was designed to fit into canoes and kayaks, but you could just as easily carry it around with you. It's a lot smaller than the other options and compresses into a little box. It's got a little seat in it and can handle several days worth of use. It costs about $75 and you can get it online here.
