Gunite vs. Fiberglass Pools in Los Angeles: An Honest Comparison
Choosing between a gunite and a fiberglass pool is the first big decision in any Los Angeles pool build. Here is the honest comparison of cost, customization, durability, and fit, with no thumb on the scale.
The two main ways to build an inground pool
Most inground pools in the Los Angeles area are built one of two ways: gunite, sometimes called shotcrete, which is a sprayed concrete shell finished with plaster, or fiberglass, which is a pre-molded shell dropped into the excavation. Both can be excellent pools when built right, but they suit different homeowners, lots, and goals.
Understanding the real differences before you commit is the best way to end up happy with the pool for decades. The cheapest option on paper is not always the best value over the life of the pool, and the most expensive is not automatically the right fit. It comes down to what you want from the pool and what your lot allows.
We build both, so we have no reason to push you toward one over the other. What follows is the honest version of the trade-offs.
Gunite: maximum customization
Gunite pools are built on site, which means they can be virtually any shape, size, or depth. If you want a custom freeform design, a vanishing edge, a beach entry, an attached spa, or an unusual depth profile, gunite is the way to get it. The shell is sprayed over a steel frame shaped exactly to your design.
That flexibility is gunite's biggest advantage. On a hillside lot, an oddly shaped yard, or a project with custom features, a gunite pool can be designed around the real constraints rather than limited to a catalog of pre-molded shapes. It is also extremely durable when engineered and built properly.
The trade-offs are time and surface. A gunite build takes longer because the shell is built and cured on site, and the plaster interior will need resurfacing every so many years as a normal part of ownership. The interior is also rougher than fiberglass, though quartz and pebble finishes smooth that out.
- Virtually unlimited shapes, sizes, and depths
- Ideal for custom features, hillside lots, and unusual yards
- Extremely durable shell when engineered and built right
- Runs quieter than older equipment
- Longer build time than fiberglass
Fiberglass: speed and a smooth surface
Fiberglass pools arrive as a single pre-molded shell and are set into the excavation, which makes for a much faster installation. Where a gunite build runs weeks to months, a fiberglass pool can often be in and running considerably sooner, because the shell is manufactured before it ever reaches your yard.
The fiberglass surface is smooth and non-porous, which means it resists staining and algae and is easy on bare feet. It also never needs replastering the way a gunite interior does, so the long-term maintenance is lower in that respect.
The trade-off is flexibility. You are choosing from the manufacturer's available shapes and sizes, and the shell has to physically fit through your yard's access to be set in place. On a tight or hillside lot, that access can be the deciding factor. Fiberglass is a great choice when one of the available shapes fits your yard and your goals.

How we help you decide
The right choice usually comes down to a few questions. How custom do you want the pool to be? How important is build speed? What does your lot and your access allow? And how long do you plan to stay in the home? We walk through all of it with you honestly.
If you want a fully custom design or have a challenging lot, gunite is usually the answer. If a manufactured shape fits your yard and you value speed and a low-maintenance surface, fiberglass can be the better fit. There is no universally correct choice, only the right one for your project.
We lay out the real numbers and trade-offs and let you decide, with no pressure toward the bigger ticket. Whichever you choose, the install quality matters more than the pool type, and that is our job.
Lifetime cost, not just the sticker
Homeowners often compare gunite and fiberglass on the upfront price alone, but the smarter comparison is the cost over the life of the pool. Gunite usually costs more to build and needs periodic resurfacing, while fiberglass costs less to install in many cases and skips replastering, though it has its own long-term considerations around the shell and the surrounding deck.
Energy and maintenance costs are similar between the two once you account for the equipment, since the pump, filter, and heater do the same work regardless of how the shell was built. Where the real difference shows up is in customization value: a gunite pool designed perfectly for your yard can add more to your enjoyment and your home than a stock shape that almost fits.
We think in decades, not in day-one dollars, and we help you weigh the full picture. The cheapest option today is not always the best value over the years you will own the pool, and an honest builder will tell you that.
Common questions before you choose
A few questions come up on nearly every gunite-versus-fiberglass decision. Can my yard fit a fiberglass shell? That depends on access, since the shell has to be craned or maneuvered into place. Can gunite do the exact shape I want? Almost always, because it is built on site. How long until I can swim? Fiberglass is usually faster, while gunite takes longer to build and cure.
Owners also ask about the surface feel. Fiberglass is smooth and easy on feet, while gunite plaster is rougher, though quartz and pebble finishes smooth that out considerably. And many ask which holds up better in the long run, and the honest answer is that both last when built right, in different ways.
We answer all of these for your specific yard and goals during a free consultation, because the right choice is the one that fits your project, not a generic recommendation.
