Loo and shower combo.

Just found this area and thought some might be interested in my design and features. First we needed a crapper but also wanted a shower area too. Shower needed to be solar. Design needed to make the most of building materials, ie. Not much waste. I also wanted to have a two hole affair so the ladies could tinkle and not have to try not to pee in the barrel. I pee outside first. Seemed to me that I could put in a hand washing sink and plumb it so it drained through the ladies pee area and thus flush it.
I built the whole thing is built around 30 gallon barrels since I get them free. I wanted to capture max winter sun so I faced S, and cut the roof accordingly for Winter solstice. Also I vented it with ABS so when it heats up the sealed barrel area draws up the hot ABS. A small screened opening let's air in from the bottom of the barrel enclosure.
It's 8X8 so two sheets of ply work out easy. Got the shower as a second at HDepot cor real cheap. The fancy French door was free from Craigs. Hey how many outdoor shitters do you know that have a French door?! I couldn't resist. So I have shit and "shine-olla" believe OT or not it OS Hung with Baldwin hinges and handle! Gota giggle at what some give for free...
If some one should have questions I'll try to answer but please be patient as this is all done off grid and on my cell phone with 50 year old thumbs...

I should say it works great! Two of us have used 3 barrels in a year. We use sawdust and worms. Flies at not an issue as it is a sealed unit when the lid is down. Think of the water saved. We truck it in so it is very precious to us.

Just a bit more. The shower drains to our comfrey and sunchokes. It gets very warm even when temps outside are 30F. Heats water way to hot to shower in. It does cool down pretty quick when the sun drops. Here are a few more photos.

Very cool!

could swear i already subscribed to this thread... hows the project coming along anyway?

This is great.. thanks for sharing!
What is your water source (you said you haul drinking water) I was wondering if using rain water or other?

Also you said it is solar powered... Do you heat the water with solar water panels and do you get water pressure via PV panels and some sort of pump?
I have a pretty rough/much less fancy version of this, and I know my wife would love it if I did something more like yours.

Nice work!
