What is the cost difference between a 14x28 and a 16x32 inground pool in Ottawa?

The size jump from a 14x28 to a 16x32 pool is more significant than it might look on paper. A 14x28 gives you 392 square feet of water surface, while a 16x32 gives you 512 square feet — that's about 30 percent more pool, and the cost difference reflects that across every component of the project.

For a vinyl liner inground pool in Ottawa, a standard 14x28 typically falls in the $45,000 to $60,000 range, while a 16x32 in the same configuration usually runs $55,000 to $75,000. That's a rough difference of $10,000 to $15,000 depending on depth profile, site conditions, and the specific contractor. Fiberglass pools follow a similar pattern, though sizing is constrained by what the manufacturer offers — you may find that the next available fiberglass shell size jumps you more dramatically in price than a custom vinyl liner would. Concrete pools scale similarly, with the larger size adding $10,000 to $20,000 over the smaller footprint.

The cost difference isn't just about the liner and the extra concrete or steel wall panels. A larger pool requires a higher-capacity pump and filter to maintain proper circulation — undersizing equipment for pool volume is one of the most common mistakes Ottawa pool owners make, and it leads to chronic water quality problems. You'll also spend more on chemicals each season, more on heating (a meaningful consideration given Ottawa's cool spring and fall shoulder seasons), and slightly more on annual opening and closing. Budget an extra $500 to $1,500 per season in operating costs for the larger pool.

One Ottawa-specific consideration worth thinking through: a 16x32 pool requires more excavation, which increases both the excavation cost and the amount of spoil that needs to be hauled away. On a tight urban lot in Barrhaven, Kanata, or Orleans, the larger footprint may also push you closer to setback limits — the City of Ottawa requires pools to sit at least 1.5 metres from property lines, so it's worth confirming your lot can comfortably accommodate the larger size before falling in love with it.

The honest answer is that the 16x32 is a meaningfully better swimming pool — more room for laps, more room for kids to play without crowding, and a more impressive backyard feature. If your budget and lot size support it, most Ottawa pool owners who upgrade to the larger size are glad they did. The extra $10,000 to $15,000 upfront tends to feel small over a 20-year ownership horizon compared to wishing you'd gone bigger.

If you're ready to get firm quotes on either size, you can browse pool contractors through the Ottawa Construction Network directory at justynrookcontracting.com/directory — getting at least three written quotes that specify exact scope, equipment specs, and permit responsibilities will give you a much clearer picture of what each size actually costs on your specific property.
