I have a 16 X 32 pool made of vermiculite bottom and polymer sides. The bottom has crumbled and the estimate I got was $2000 -4000.00 to redo. Is there a way to change it from a vinyl liner to a pool without a liner. I have had the pool company put 3 liners in the past 10 year and they don't last. Is there any other solution to change the style of pool (fiberglass, etc.).
