Picking a pool type is the first real decision in the whole build, and it’s the one that shapes everything after it: your budget, your timeline, and how much weekend time you’ll spend maintaining it for the next twenty years. Northwest Arkansas homeowners in Rogers, Bentonville, Centerton, Lowell, and Fayetteville have three solid options: gunite, fiberglass, and vinyl liner. Each one does something well and asks something of you in return.
This guide breaks down what each type actually costs, how long it lasts, what it takes to maintain, and which one fits your specific situation, backyard, and budget.

Gunite Pools
A gunite pool is built entirely on-site. A steel rebar frame goes in first, then a concrete and sand mixture gets sprayed over it under high pressure, and the whole thing gets finished with plaster, pebble, or tile.
That on-site build is exactly what makes gunite the most flexible option on this list. There’s no mold to work around, so the shape, depth, and features are limited only by your backyard and your budget. Vanishing edges, tanning ledges, attached spas, and custom depth changes are all realistic with gunite in a way they simply aren’t with a pre-formed shell.
The tradeoff is time and upkeep. A gunite build in NWA typically runs two to four months from ground-breaking to first swim, and the porous surface needs regular brushing to stay ahead of algae plus resurfacing roughly every 10 to 15 years.
Gunite fits you if: you want a specific shape or feature set that off-the-shelf options can’t deliver, and you’re comfortable with more upfront cost and ongoing maintenance in exchange for a truly custom pool.
Fiberglass Pools
Fiberglass pools arrive as a single pre-manufactured shell, built off-site and lowered into an excavated hole by crane. Because most of the work happens before the shell ever reaches your property, installation is fast, often just a couple of weeks once the site is prepped.
The gel coat surface is smooth and non-porous, which means less algae, less scrubbing, and fewer chemicals to keep the water balanced compared to gunite. It’s the lowest-maintenance option of the three by a wide margin.
The limitation is shape. You’re choosing from a manufacturer’s existing mold library rather than designing from scratch, and larger shells can be tricky to get into backyards with tight access or steep grade changes, which shows up more often than people expect on Ozark foothill lots around Bentonville and Rogers.
Fiberglass fits you if: you want a pool up and running fast with the least ongoing work, and you’re fine choosing from a strong lineup of pre-designed shapes rather than a fully custom one.
Vinyl Liner Pools
Vinyl liner pools use a steel or polymer wall frame with a custom-fitted vinyl liner stretched over it to hold the water. The frame goes in on-site, so unlike fiberglass, you’re not locked into a factory mold. Shape and depth can be built to fit your yard.
This is the lowest upfront cost of the three, often by a meaningful margin, and the surface is smooth and comfortable underfoot. The catch is the liner itself. Depending on water chemistry and sun exposure, most liners need replacing every 7 to 10 years, and that’s a real recurring cost to plan for over the life of the pool.
Vinyl liner fits you if: budget is the top priority, or you want a custom shape without paying gunite-level prices, and you’re okay with a liner replacement every decade or so as part of ownership.
Cost at a Glance
Exact pricing depends on size, features, and site prep, but here’s what NWA homeowners are generally looking at by pool type:
- Vinyl liner: typically starts around $40,000 to $70,000 installed. Lowest entry point of the three, with liner replacement (roughly $4,000 to $7,500) as the main cost to plan for every 7 to 10 years.
- Fiberglass: typically runs $55,000 to $100,000 installed. Higher upfront than vinyl, but the near-zero resurfacing and lower chemical costs often close the gap over a 15 to 20 year span.
- Gunite: typically starts around $60,000 and climbs from there with customization, easily reaching $100,000+ for larger or highly custom designs. Highest build cost, plus resurfacing every 10 to 15 years at $8,000 to $15,000 or more depending on finish.
If you’re comparing sticker price alone, vinyl liner wins every time. If you’re comparing 20-year cost of ownership, fiberglass often pulls closest to even with vinyl once you factor out liner replacements and lower chemical use.
What NWA Backyards Actually Deal With
Local ground and weather change this decision more than most guides let on.
Freeze-thaw cycles. Northwest Arkansas gets real winter freezes, and that shift between freezing and thawing puts stress on pool structures and plumbing. Gunite handles this well once properly built and winterized, but corners cut on rebar depth or plumbing insulation show up as cracks within a few seasons. Fiberglass shells flex slightly with ground movement, which helps in freeze-thaw conditions. Vinyl liner pools do fine too, as long as the water level and winterization are managed correctly each fall.
Ground conditions. The rocky, sloped terrain common around Bentonville, Rogers, and the Ozark foothills can complicate excavation for any pool type, but it affects each one differently. Gunite adapts well since it’s formed on-site to match uneven ground. Vinyl liner frames offer similar flexibility. Fiberglass shells need a fairly level, accessible excavation site for the crane placement, so a heavily sloped or rock-heavy lot may need additional site work or grading before a fiberglass install is realistic.
Access for delivery. If your lot in Centerton or Lowell has a tight driveway or limited backyard access, that matters most for fiberglass, since the whole shell has to physically get to the hole. Gunite and vinyl liner materials are far easier to bring in piece by piece.
Which Pool Type Fits Your Situation?
If budget is your top priority: vinyl liner. Lowest cost to break ground, and the shape flexibility means you’re not sacrificing much on design.
If you want minimal maintenance for years at a time: fiberglass. The non-porous surface cuts down on brushing, chemicals, and algae fights more than either other option.
If you want a fully custom shape or built-in features like a spa or tanning ledge: gunite. Nothing else on this list gives you that level of design freedom.
If your lot has steep grade changes or tight access: gunite or vinyl liner will likely be easier to build than fiberglass, worth discussing with your builder before you fall in love with a shell design.
If you’re replacing an aging pool: vinyl liner is often the most cost-effective way to refresh an old gunite pool without a full rebuild, while gunite resurfacing makes sense if the structure itself is still sound.
Frequently Asked Questions (FAQ)
Which pool type lasts the longest?
Gunite structures can last 50 years or more with proper care, though the surface needs resurfacing roughly every 10 to 15 years. Fiberglass shells commonly last 25 to 30+ years with minimal structural upkeep. Vinyl liner pool structures can also last decades, but the liner itself needs replacing roughly every 7 to 10 years.
Which pool is cheapest to install?
Vinyl liner pools typically have the lowest upfront cost, followed by fiberglass, with gunite as the most expensive to build due to the labor and site work involved.
Which pool is cheapest over the long run?
Fiberglass tends to come out ahead over a 15 to 20 year window since it avoids both resurfacing and liner replacement. Vinyl liner has the lowest starting cost but adds up with liner swaps every 7 to 10 years at $4,000 to $7,500 each. Gunite costs the most overall between the higher build price and resurfacing every 10 to 15 years, but for homeowners who want full customization, that cost buys design freedom the other two can’t match.
Can I convert a vinyl liner pool to gunite later?
Yes, this is a common renovation. It typically involves removing the liner and wall panels, then rebuilding the shell in gunite. It’s a bigger project than a standard liner replacement, so it makes sense to talk through the scope with a builder who handles both pool types.
Does BC Pools NWA build all three pool types?
Yes. BC Pools builds gunite, fiberglass, and vinyl liner pools for homeowners across Bentonville, Rogers, Fayetteville, Springdale, Lowell, and Centerton, so the recommendation you get is based on your yard and goals rather than what one product line happens to sell.
