Gunite, fiberglass, or vinyl liner: which pool should you build?
All three are real options. In Scottsdale, the lot, the design you want, and how soon you want to swim usually decide it.

The short answer
If you want a custom shape, a spa spillover, a beach entry, or anything else unusual, pick gunite. Pick fiberglass if a standard shape works for you and you want to swim sooner with less resurfacing down the road. Choose vinyl liner only if budget comes first and you are prepared to replace the liner periodically.
Pick gunite if
- You want full design control. Latham, a maker of fiberglass and vinyl pools, says concrete pools offer many customization options but take a lot of planning to design.
- The design includes features that need their own engineering. See special features and engineering.
- You are fine with a longer build. Latham says gunite pools can take about three to six months from permit to finishing touches.
Pick fiberglass if
- A shell shape from a catalog fits your yard and your access.
- Speed matters. Latham says a fiberglass pool can be ready to use in as little as three days after delivery. That is the manufacturer's best case, so permits, the barrier, and inspections still set the real schedule.
- You want to avoid resurfacing. Latham says concrete pools need resurfacing about every ten years. Treat that as a competitor's figure, but the shell versus plaster difference is real.
- Check that a crane or truck can get the shell into your yard.
Pick vinyl liner if
- Upfront budget matters most.
- You accept the upkeep. Latham says liners are replaced about every ten years on average.
Scottsdale specifics
Whatever the type, the City's permit, engineering, and barrier rules still apply. See permits and engineering and standard plans. On NAOS or hillside lots, access and grading can rule some options out. See NAOS and ESL lots.
Where we land
Gunite remains the default for Scottsdale custom builds. Fiberglass is the pick for buyers who want a simpler shape and less resurfacing, and vinyl is a budget option to choose knowingly.
Questions
Which one lasts longest?
Each can last a long time with care. They differ in what wears out: plaster for gunite, the liner for vinyl, and the gelcoat finish for fiberglass.
Is the source biased?
Latham sells fiberglass and vinyl, not gunite, so weigh its claims accordingly.
