That pool will puncture as soon as it sees a bulkhead
When I stripped some house doors a few years back, I dry laid a brick enclosure. Draped a bit of Visqueen damp proof membrane over them to form a pool, put one more layer of bricks on top of the walls to hold it from blowing about, and filled it up with caustic soda solution. Worked very well
