The lowest upfront cost of any inground pool — with a liner replacement cycle that every honest comparison has to include.
Vinyl makes sense for budget-first buyers and for yards where a fiberglass shell cannot be delivered — tight-access lots in older suburbs, for example, where panels can be carried in by hand but a crane cannot reach. It makes less sense as a “cheapest forever” choice: over twenty years, liner replacements narrow or erase the upfront gap with fiberglass, while fiberglass keeps its maintenance edge every one of those years. If you choose vinyl, choose it for the upfront price and the shape flexibility, with eyes open about the liner cycle.
Ask for the liner spec. Get the liner thickness (mil), pattern, and warranty in writing, plus a written price for a future liner replacement from the same builder. That number is the honest second half of the vinyl price.
