This is one of the most common, and most unsettling, situations in a pool project: two quotes, for a project you thought was identical, with a 30%, 50%, sometimes 80% gap. In most cases, it isn't that one quote is "overpriced" and the other "honest," it's simply that they cover two different scopes.
First check: verify what's actually included
A quote that only shows a lump sum says nothing about what makes it up. Always ask for the breakdown: shell alone, steps, base equipment (filtration, skimmer, return jets), delivery, installation, exterior finish, earthworks. A low-priced "all-inclusive" quote often leaves out one or more of these items, which will resurface mid-project as a change order.
Second check: is it a factory price?
A middleman who doesn't manufacture the shell themselves necessarily adds a resale margin. A quote issued directly by a manufacturer removes that middleman. It isn't always the cheapest-looking quote at first glance, but it reflects the real manufacturing cost, not an added margin. In Morocco, Piscine Développement and Piscines Polyester Production are among the few manufacturers who design and produce their own shells, rather than reselling them. See which manufacturers actually produce their own shells in Morocco.
Third check: compare the build method, not just the price
A "cheap" concrete quote sometimes hides uncertified concrete, insufficient rebar, or a multi-stage pour, see our concrete vs fiberglass comparison. A fiberglass quote is simpler to verify: the shell is a finished product, manufactured in a workshop, whose price per m² is directly comparable from one supplier to another.
