Fish scale height adjustment
The interlocking column twists open and locks anywhere between 4 inches and 15.8 inches across seven height steps. Twist it down flat to ride under a cargo board, or pull it all the way up to match standard seat height.

We built this retractable toilet around an adjustable fish scale column that clicks into seven distinct heights. A soft PU cushion tops the seat, and the kit includes two 20-bag rolls made from PBAT and PLA film that hold waste without seeping for a full day.

The interlocking column twists open and locks anywhere between 4 inches and 15.8 inches across seven height steps. Twist it down flat to ride under a cargo board, or pull it all the way up to match standard seat height.
The rim is topped with a soft PU cushion that stays forgiving under weight and wipes clean with a damp cloth. It replaces hard plastic edges with a surface that stays comfortable in cold weather and hot sun alike.
We pack this set with 40 plant-based bags built from PBAT and PLA without added corn starch. The material resists water seepage for twenty-four hours and decomposes in soil over six months after burial.
Two full rolls of liners pack directly with the collapsed base into your camp bin. When you set up, pull the column to height, hook a liner over the cushioned rim, and push the base flat against the dirt.
Pieces that ride along in the same trunk or pair with this one at camp.
