Gunite Pools in Orange County: How Custom Pools Are Built & What They Cost

Nearly every custom pool in Orange County is a gunite pool — a steel-reinforced concrete shell sprayed on-site and shaped to the yard instead of picked from a catalog. This guide covers what gunite construction actually is, why it's the standard for custom pools here, how it compares to fiberglass and vinyl, and what gunite pools cost in 2026 — with real Orange County builds as examples.

What Gunite Construction Actually Is

A gunite pool starts with a hand-tied rebar cage shaped to the pool's exact footprint, then concrete is sprayed onto the steel at high pressure — gunite is the dry-mix method, where water is added at the nozzle; shotcrete is the wet-mix cousin. Crews hand-shape the shell while it cures into a single, continuous concrete structure, and the waterline tile, coping, plumbing, and equipment all tie into that shell.

The finish is what you touch: plaster or aggregate finishes like PebbleTec are applied over the cured gunite, giving you the color and texture options — quartz, glass bead, pebble — that make each pool look custom rather than catalog.

Why Orange County's Custom Pools Are Gunite

  • Unlimited shape and size — freeform lagoons, clean geometric lap pools, baja shelves and tanning ledgers, all drawn to fit the actual yard
  • Handles Orange County lots — tight side-yard access, hillside slopes, and coastal setbacks that a one-piece factory shell can't navigate
  • Structural strength — a reinforced concrete shell is the right pool for seismic country, engineered and inspected before shotcrete
  • Longevity — the shell routinely lasts decades, with remodels refreshing the finish, tile, and equipment instead of replacing the pool
  • Feature integration — raised spas, sheer descents, infinity edges, and grottos are built into the shell as one structure, not bolted on

Gunite vs. Other Pool Construction Methods

  • Fiberglass — a one-piece factory shell delivered by crane; fast install but limited shapes, sizes, and depths, requires crane access, and you can't add a spa, baja shelf, or infinity edge later
  • Vinyl liner — the least durable option and rare in Southern California; liners need replacement cycles and the frames don't support custom features
  • Gunite / custom — unlimited design, premium interior finishes, and the longest service life; the only method Coastline builds with, because it's the only one that delivers a true custom pool

Real Gunite Pools We've Built in Orange County

Our Irvine build shows gunite's design precision: a clean, architectural pool with a PebbleTec interior, glass tile waterline, and an outdoor kitchen integrated into the deck — a shape drawn for that lot, not adapted to it.

The Villa Park estate build shows feature integration at full scale: a custom gunite pool and spa with premium finishes, integrated water features, and a complete outdoor living package built as one structure. And our Huntington Beach build — a rectangular gunite pool with raised spillover spa, sheer-descent waterfall, gas fire pit, and LED lighting — shows how a classic shape still gets fully custom features. All three are linked in the Keep Reading section below.

What a Gunite Pool Costs in Orange County (2026)

The typical Coastline gunite project starts around $60,000 — compact cocktail pools run $60,000–$80,000, the standard custom range is $85,000–$120,000, and luxury estate builds with spas and water features routinely exceed $150,000. Access, engineering, finishes, and features drive where a project lands.

Our Pool Cost Guide breaks the number down line by line — permits, engineering, excavation, finishes, and add-ons — so you can compare bids on scope instead of bottom dollar.

Gunite Pool FAQs

A pool built by spraying concrete at high pressure over a hand-tied rebar cage, forming a single reinforced shell that's then finished with plaster, PebbleTec, or another interior finish. The shell is shaped on-site, which is why gunite pools can be any shape or size the lot allows.

For a truly custom pool, gunite. Fiberglass installs quickly but comes in factory shapes with limited sizes and needs crane access; you can't add a spa, baja shelf, or infinity edge later. Gunite costs more upfront but offers unlimited design, premium finishes, and a shell that lasts decades. It's the only method we build with.

The shell routinely lasts 25+ years — often far longer — with interior finishes lasting 10–15 years before a remodel refreshes them. Remodeling a gunite pool (new finish, tile, coping, equipment) restores it at a fraction of new-construction cost, which is why shells from the 1970s are still in service across Orange County.

The typical project starts around $60,000: compact pools run $60,000–$80,000, standard custom builds $85,000–$120,000, and luxury builds $150,000+. See our Pool Cost Guide for the full line-by-line breakdown.
