Design & Pool Types

Gunite, Fiberglass, and Concrete Pools: How They Actually Compare

"Gunite vs. concrete" is a bit of a false choice, gunite is a concrete pool, built a specific way, which is worth untangling before comparing it to fiberglass. Bridgeland and Towne Lake both route pool and backyard plans through an HOA architectural control committee before construction, and lakefront or lake-adjacent lots carry their own drainage and setback rules on top of that.

Gunite Is a Concrete Pool, Not a Third Option

All concrete pools are built the same basic way: a steel rebar structure is shaped to the design, then concrete is applied over it and finished. The distinction homeowners usually mean by "gunite vs. concrete" is actually about application method. Gunite is a dry-mix concrete, water is added at the nozzle as it's sprayed under pressure, and it's the dominant method for residential pools in Texas. Shotcrete is a closely related wet-mix sprayed method that produces a similar end result. Older-style poured concrete, mixed and poured into wooden forms rather than sprayed, is rare in residential pool construction today because spraying allows far more control over custom shapes and depths. For nearly every practical purpose, "concrete pool" and "gunite pool" describe the same thing in this market.

Cost: Where the Numbers Actually Land

Fiberglass shells are manufactured off-site and often carry a lower starting price for a comparable size, since there's less on-site labor and a shorter build. Gunite starts higher because of the custom, multi-phase, hand-finished construction process, but the gap narrows, and can disappear, once a fiberglass project adds enough custom features and upgraded finishes to approach a comparably-equipped gunite build. Size, depth, and feature list move both numbers more than the construction method alone does.

Installation Timeline

Fiberglass is the faster path: the shell is set in one piece and can often be filled within days to a couple of weeks once plumbing and decking are finished. Gunite runs several months end to end, driven mainly by sequential phases (excavation, steel, spray, a roughly month-long cure, then plumbing, decking, and finish) rather than any single slow step. Permitting and, where applicable, HOA review add time on top of either method, and run in parallel with design rather than after it.

Durability, Lifespan, and Resurfacing

A properly engineered gunite shell, built for local soil conditions, commonly lasts the life of the home with periodic resurfacing. Plaster or pebble finishes on a gunite shell typically need redoing roughly every 10 to 15 years as the surface wears, separate from the structural shell itself, which doesn't need replacing on that schedule if it was engineered correctly. Fiberglass shells hold up well structurally over decades, and the gel-coat surface resists staining and algae better than plaster day to day, but gel coat can fade or show hairline surface wear over a long enough timeline, and because the shell is a single manufactured piece, a significant structural repair is a different, more specialized undertaking than resurfacing a gunite shell.

Customization and Shape

This is where the two methods diverge most. Gunite is sprayed and hand-shaped on-site, so depth, shape, tanning ledges, raised spas, and integrated water features can all be designed around the specific lot rather than chosen from a catalog. Fiberglass comes in a fixed set of manufacturer molds; modern mold lineups include a wide range of shapes, built-in tanning ledges, and spa configurations, but the design is ultimately selected from what's available, not drawn from scratch.

What This Builder Actually Offers

Gunite and fiberglass are the two construction methods built here, gunite for a fully custom shape and feature set, fiberglass for a faster build and lower day-to-day maintenance. Vinyl-liner construction and old-style poured-form concrete aren't part of the service lineup; see Pool Services for the full breakdown of what's built and how the two methods are scoped during a site evaluation.

FAQs

Is shotcrete better than gunite?

They're closely related sprayed-concrete methods (dry-mix for gunite, wet-mix for shotcrete) that produce a comparable finished shell; the choice often comes down to a crew's equipment and experience rather than one method being categorically better than the other.

Why do some sources treat "concrete" and "gunite" as different pool types?

Usually to distinguish sprayed construction (gunite/shotcrete) from older poured-into-forms concrete construction, which is rare in residential pools today, or simply as informal shorthand; structurally, a gunite pool is a concrete pool.
