| === operation === |
| |
| **Before inital use** a layer of [[toilet:composting#media|media]] goes in the bottom of the bucket; this makes cleanup easier if the liner breaks. Then a kitchen trash bag or other liner is placed in the bucket and a layer of media((an inch or so)) is added. |
| |
| **After pooping in the bucket** the deposit is covered with another layer of media. |
| |
| To **clean out the bucket**: remove any lid, tie off the bag or liner, and remove from the bucket. Toss in a dumpster as one would baby diapers or dog droppings. Install a new liner and bottom layer of media. |

| === bucket === |
| The bucket is an ordinary 5-gallon bucket, as one might find at a home improvement store, food prep area, or the side of the road in a ditch. :-) |
| |
| For those with less space, there are reports that some 3.5 or 4 gallon buckets have the same top dimensions as the larger 5 gallon units.((http://www.cheaprvliving.com/forums/Thread-Smaller-bucket-for-Luggable-Loo-seat)) This might be important if you are planning to use a commercial seat/lid. |

| === seat/lid === |
| |
| One can use a normal lid over the bucket when not in use, but this precludes the attachment of a commercial lid (below). The rim is quite narrow and can be uncomfortable to sit on directly. Because of this, some use a length of pool noodle split down the middle and pushed down on the rim. It has to be removed again to replace the lid. |
| |
| The most common commercial seat/lid the [[http://amzn.to/2lCyGHT|Luggable Loo]]. It snaps onto the top rim like a bucket lid would. |
