Owner Built System Designs

Below are some selected do-it-yourself composting toilet system designs.

Composting Toilet World makes no claims as to the quality of these plans.

Pure Portugal Composting Toilet

This is not exactly ower-built, because it is done by someone else. But, it also does not really qualify as a manufactured system.

From Pure Portugal:

“Pure Portugal can build you a basic compost toilet from as little as 300 euros, a fraction of the cost of a water-consuming and environment-damaging septic tank.

Pictured is our most basic design for a compost toilet (photo taken before the door - in this case simply a curtain - or toilet seat were added).

Big Batch Composting Toilet

An owner built system that utilizes readily available materials. It is designed around a large rolling polyethylene dump cart (North American style) with air pipes of PVC placed into it. Two are used, one “resting,” while the other is filled.
