Installation instructions for Bog Standard compost toilet
Groundworks
Most of the work involved in setting up the compost toilet will be in preparing the base for the toilet. We recommend leveling the area about a foot wider than the footprint of the toilet and scraping back the top soil. Then either put a layer of gravel about 2” thick around the toilet or a geotextile weed suppressant. This is to stop grass from growing up the side of the building.
As all external wooden buildings rot from the ground up, we advise raising the toilet above the ground by using bricks around the perimeter of the footprint. This does not have to be a continuous line of bricks and is better if there are fewer bricks and therefore fewer contact points between the toilet and the earth. 7 bricks should be sufficient. Make sure to keep the back opening clear for the wheelie bin.
Installation of Compost Toilet
All you will need are two people and a cordless drill with pozi 2 and hex bits. Move base pieces into place. Align base with markings and screw front panel onto sides with hex screws.
Make sure the distance is equal between the right and left panel and then screw brace piece into place.
Lift roof onto toilet and align with markings. The roof is overhanging on the front and flush to the back of the toilet. Fix into place making sure that the door closes into the latch.
Insert 25l urine container into side door and feed in urine pipe from separator.
Move wheelie bin into back door and turn it sideways and position it as close to the front as possible and as central to the toilet seat hole as possible.
It is important to secure the whole building to the ground with some sort of anchor if you are in a windy spot. We recommend hammering a fence post into the ground inside the base frame and screwing onto the base frame. This step would be best done before the toilet sides are erected. The best place for this fence post is on the inside opposite the small door to the urine container.
