What actually drives pool cost
Two pools with the same footprint can differ by 3× in price. Here's where the money actually goes.

Size and depth: the base multiplier
Excavation, concrete, waterproofing, finish, water, heating — all scale with volume. Our plan pages compute volume and excavation for every size; compare an 8 × 4 to a 10 × 5 and you'll see the jump. The cheapest cubic metre of pool is the one you don't build — right-sizing beats every discount.
The edge system: the hidden fork
Going from skimmer to deck-level overflow adds a perimeter channel, balance tank and precision leveling — typically +15–30% on the shell. It buys the best water quality and the best look, but decide it early: it shapes the structure, it's not a later upgrade.
Finishes: where budgets quietly double
Interior finish, coping and deck are the visible money. Paint → plaster → porcelain tile spans roughly 1×–3× on the interior; deck material and area often cost as much as the pool shell. The classic save: porcelain waterline band plus plaster body, and a deck that starts generous on the lounging side and modest elsewhere.
Equipment and site: the fine print
Heat pump, automatic cover and quality lighting are the big equipment lines — worth their money in usability. Site conditions are the wildcard: rock, groundwater, poor access or a slope can add serious cost before any pool exists. A site visit beats any online estimate, including ours.
Frequently asked questions
- What's the single best place to save?
- Size. A right-sized pool with a cover and good finishes beats an oversized bare one on every metric, running costs included.
- What should I never save on?
- Waterproofing and groundworks. Everything above them can be renewed; a leaking shell is misery.
- Do accessories cost much?
- Masonry (steps, ledges, benches) is formwork and labor — moderate. Equipment (cover, heat pump, counter-current) is where accessory budgets jump.
