Snap rim fit
The underside latches directly onto bucket rims between 11.91 and 12.5 inches across. It locks down firmly with downward pressure and pops off when you pull the edge.

We built this seat to turn a standard 5 gallon bucket into a solid camp toilet. High-density polypropylene beams support up to 300 pounds without flexing. The removable padded cushion wipes down quickly, and the lid swings back 270 degrees to stay clear during use.

We added a removable PU cushion to soften the rim. It blocks the chill of bare plastic on cold mornings and unhooks completely so you can wash it with soap and water.
A 270-degree hinge lets the lid rotate completely back against the bucket wall. It stays out of your way while seated and closes flat over the opening when camp is packed.
A clip-on side spindle holds a standard roll of toilet paper right next to the bucket rim. The top shelf gives you a flat resting spot for a phone or a flashlight.
