A method for fabricating a pool mold comprising the steps of creating a recess, the recess having the general shape and contour of the desired finished pool and is installed with support materials and surface references. A layer of forming material is place over the support materials and surface references and formed to desired contour and grade. The forming material has substantially uniform coefficients of thermal expansion and heat transfer. The surface of the recess is sealed and coated with a release agent. A mold is then fabricated within the recess.
