I don't have the skills to build a nifty throne for our shit bucket, and my one attempt at adapting a wooden regular toilet seat lid to a bucket promptly resulted in the lid falling off and breaking (luckily with no messier damage than that). So we still use a plastic toilet seat contraption designed for camping which snaps onto the top of a 5 gallon bucket. (We bought two back in 2005 from the local survivalist shop for $10 each, give or take.)
We used one bucket for poop and pee for a while, but eventually decided to add a bucket just for pee. This allows us to return nutrients to our garden more quickly, reduces the frequency with which I have to dump the poop bucket into the compost pile, and reduces the amount of sawdust we need to use. Enough moisture seems to make it into the compost pile between what urine does go in and the water from cleaning out the poop bucket when I dump it, that the compost pile still seems to get plenty hot and doesn't require extra water in the summer. I empty the pee bucket every 2-3 days (generally when it start to smell, which besides the obvious cue of unpleasantness also tells us we're losing nitrogen to the air). I empty the poop bucket maybe every three weeks or so.
So our bathroom currently has a poop bucket, a sawdust bucket (center), and a pee bucket (left). The standard ceramic toilet makes a fine stand for toilet paper, phone book pages for those who don't want to wipe their ass with trees killed just for that purpose, and candles and incense because Theressa likes that sort of stuff.
Way back when we tore out the driveway in a big work party, I wrote up instructions for how to use our bathroom, just in case it confused anyone. Occasionally when we have normal core folks over we clear the normal toilet off so they can easily choose their preference, but I think only about three people have used the ceramic toilet in the last year.
I haven't measured the temperature of the compost pile. When I shovel out a little hole in the center of the compost pile for the new additions, I put my hand over the divot and always feel some heat, which satisfies me that things are working. We plan to follow the schedule of one year to actively build the pile, then start a second pile and build that for a year while the first pile sits. So everything in each pile will sit for at least one year, and up to as long as two years, which should adequately kill off any potential pathogens.
I don't know what else to say, so I'll leave it at that unless I get any questions!
