When we first started designing vinyl-lined DIY pools in the 80s, it was almost impossible for families to have a really nice, good looking swimming pool that didn’t cost many, many thousands of dollars, whether they were professionally installed in-ground, or the above ground style. These days, there are a lot more options available to families and homeowners, but we’ve decided to include several of our most popular DIY swimming pool designs for those who want a fun family project that provides years of enjoyment and healthy exercise.
