Castillo Pools is a UK based designer and manufacturer of stainless steel precision engineered swimming pools. The Castillo team is unique in combining over a quarter of a century experience in pool design and installation with state of the art engineering skills to create precision engineered pools of any size, shape or design. We have developed a proprietary pool panel system from which pool shells can be quickly assembled on site using only handheld tools. Each panel system pool is structurally self supporting requiring neither backfill or concrete ring beam as additional support.
