Before Ogo Composting Toilet 1

Above: The original OEM toilet

I switched to an Ogo composting toilet for several reasons. I’ve never liked dumping the black tank. Does anyone like it? I also wanted to increase our off-grid time.

First, I removed the flush toilet and the water line. Then, I flushed out the black tank. I sealed the flange with a piece of ridged plastic and silicone.

Next, I made a paper template of the area. I used a piece of 3/4-inch plywood that I had in the garage, cut it to the template and routed out where the toilet flange was. Then, I sanded and painted the plywood.

I drilled a hole for the 12-volt wire. The 12-volt wire is for the small air circulation fan which is all that need to be hooked up. There is also an external vent that could be hooked up which I’m hoping not to use. That’s mainly because I don’t want to drill a 1.25-inch hole in the side of the camper.

Finally, I lined up the toilet and screwed it to the plywood. Ogo sells charcoal filters to put in the vent line so you it isn’t necessary to vent it outside.

Ogo Composting Toilet 6

So far we have been very happy with the toilet. It works as described. I still may vent it outside.

After Ogo Composting Toilet 2 supplied everything I needed for mounting their composting toilet. I used a piece of plywood a couple of screws and electrical connectors I had in my garage.

It took me six hours approximately hours to complete this modification and cost me $1,200.  In my opinion, the skill level of this modification is medium.
