Most people picture a fiberglass pool going in over a weekend. A truck pulls up, a crane swings the shell into a hole, and the kids are swimming by Friday afternoon.
That is not how a good build works in Tulsa. The pools that go in fastest often settle or crack their decks later.
This guide walks through every step of fiberglass pool installation the way we do it at Silverado Rock. You will see what happens at each stage and why the stone around your pool matters more than the shell itself.
Later, you will read about a Broken Arrow pool where the sand behind the shell washed away. That story explains the one step most buyers never ask about.
How Long Does It Take to Install a Fiberglass Pool in Tulsa?
Most fiberglass builds at Silverado Rock take 4 to 6 weeks from dig day to first swim, including shell delivery. Permits come first and take about 1 to 4 weeks, depending on your city.
The shell sets in a single day, but setting the shell is only one of ten steps. The base, plumbing, backfill, tile, and deck all take real time, and rushing any of them costs you later.
| Pool Type | Typical Build Time | What Sets the Pace |
|---|---|---|
| Vinyl liner (OK Plunge) | About 26 days | Wall panels and liner fit |
| Fiberglass | 4 to 6 weeks | Shell delivery, base, backfill, tile, and deck |
| Custom gunite | 3 to 6 months | Shell cure and plaster, counted from contract signing |
Rain and permit waits can stretch any schedule, but they cost you time, not added dollars on your contract.
Bottom line: plan your summer around 4 to 6 weeks of building, not 4 to 6 days. If you have a swim date in mind, count back from it and leave room for weather.
The 10 Steps of Fiberglass Pool Installation at a Glance
| Step | What Happens | What You Do |
|---|---|---|
| 1. Design visit | We walk your yard and build a 3D design | Tell us how your family wants to use the yard |
| 2. Permits and locates | We handle the permit and request utility marks | Sign a few forms |
| 3. Shell order | Your Leisure Pools shell is ordered, and a delivery date is set | Pick the model, size, and color |
| 4. Excavation | The hole is dug, and the dirt is graded or hauled | Keep cars, kids, and pets clear |
| 5. Base and groundwater | A chip stone bed and a groundwater relief pipe go in | Nothing |
| 6. Shell set | The shell arrives and is set level on the stone | Watch. This is the fun day |
| 7. Plumbing, equipment, and power | Jandy equipment, pipe, and wiring go in | Approve the equipment pad spot |
| 8. Backfill | Chip stone fills every gap around the shell | Nothing |
| 9. Tile, coping, and deck | Waterline tile, coping, and the concrete deck go in | Choose tile and deck finish |
| 10. Startup | Water is balanced, and you get pool school | Learn your pool, then swim |
Step 1: What Happens at the First Site Visit?
Our owner walks every yard himself, and no salesperson comes first. The visit takes about an hour, and it is free.
We study the slope, the soil, and where water runs after a storm. We also check gates, fences, trees, and power lines, since those decide how the shell reaches your yard.
Then we build a 3D design in Pool Studio showing the pool, the deck, and later extras like an outdoor kitchen or fire pit. That way, you see the finished yard before anyone digs.
This visit is also where we pick the skimmer spot. For much of the year, Oklahoma winds blow out of the south, and the Oklahoma Mesonet tracks those winds across the state. So we put the skimmer on the northwest side whenever the house allows it. That way, the wind pushes leaves toward the skimmer instead of into a corner you have to net by hand.
Pro Tip: Ask every builder where the skimmer goes and why. If the answer is "wherever it fits," that's a signal.
If you have a dog, please tell us at this visit. We steer dog owners toward a shell whose steps sit closest to the house. That placement gives your dog one clear, easy way in and out of the water.
Step 2: Permits and Utility Locates
We coordinate the pool permit for you anywhere in the Tulsa metro. You sign a few forms, and the permit process takes about one to four weeks, depending on the city. The permit fee isn't included in our price, so budget for it. Our Tulsa pool permits guide covers each city in detail.
Before anyone digs, Oklahoma law requires an OKIE811 locate request. Submit the request at least 48 hours in advance, excluding the day of the request, weekends, and holidays. Utility companies then mark buried gas, power, and cable lines with paint or flags. The locating service costs nothing, and the digging crew must file it.
Step 3: How Do You Pick the Right Fiberglass Shell?
Silverado Rock is an Elite Leisure Pools dealer in Tulsa, and we picked Leisure for what goes inside the shell, not only its looks.
A fiberglass shell is layers of glass fiber held together by resin. Leisure says resin makes up nearly 70 percent of a shell, so it determines how well the shell keeps water out.
Most shells in the industry use ordinary polyester resin. Some manufacturers add a single vinyl ester barrier layer and fill the rest with cheaper polyester. Leisure builds its shells entirely with vinyl ester resin, which bonds better between layers and is less likely to show stress cracks.
Why should you care in year 12 instead of year 1?
The reason is osmosis.
Over time, water works its way into a shell's layers and forms blisters under the surface. Leisure backs its shells with a lifetime structural warranty and a lifetime structural osmosis warranty. The gelcoat surface carries its own 10-year warranty, and Leisure Pools' full warranty details are on its site.
Ask any builder which resin the shell uses and whether the osmosis warranty is in writing.
Because shells travel by road, a truck limits how big they can get. Inside that limit, you choose the model, size, depth, color, and features like benches or a tanning ledge. Then we order your shell and set a delivery date, which locks in the schedule.
Step 4: What Happens on Dig Day?
The excavator digs a hole a bit larger than the shell, leaving about 2.5 feet of working room around the outside. The plumbing crew works in that gap, then fills it completely with chip stone.
Much of the Tulsa metro sits on heavy clay, which swells when wet and shrinks when dry. That movement pushes on anything buried in it. Any pool type can go into Tulsa clay, and the build quality determines how well it holds up. You can look up the soil on your own lot with the USDA soil survey.
Some yards also hide rock under the surface. That matters because your quoted price is fixed unless we hit buried rock. If the excavator hits a rock ledge nobody could see from the surface, removing it adds cost. We show you what the crew found before anything changes.
Pipes can hide too, so imagine a sewer clean-out running right through where the pool will go. A plumber would have to move it, and it is far better to find that at the design visit.
Rain is the other surprise, because after one storm, a fiberglass excavation we had just dug filled up with rainwater. We had to pump it all out, and that job took most of the day. That is why we watch the NWS Tulsa forecast closely around dig day.
Some yards can reuse the dirt to regrade low spots. Others need it hauled off, and hauling is not in our price.
A fair warning: during excavation, your yard will look about 10 times worse than you imagine; we barricade the work area so dogs stay out of the dig and don't track mud into the house.
The hole is the easy part, but what goes in the bottom of it decides how long your pool lasts.
Step 5: Why Does the Base Matter More Than the Shell?
A fiberglass shell is light for its size, so think of it like burying a boat in your backyard.
A boat floats, and a fiberglass pool will try to do the same thing whenever groundwater builds up underneath it. That upward push from below is called hydrostatic pressure. Spring rain in Tulsa can quickly raise groundwater, and clay soil holds that water against the pool.
Here is how we build the base to stop that:
- A chip stone bed. We put at least 4 inches of 3/8-inch chip stone in the bottom of the hole. Some spots get 5 to 7 inches, and we set the shell on that stone, never on sand or loose dirt.
- Dry compaction. We level and compact the stone dry, with no water jetting to settle it.
- A groundwater relief pipe. A pipe sits in the chip stone at the deep end and comes up under a cap in the deck. If groundwater rises, a pump drops into that pipe and pulls the water out before it can push on the shell.
Some builders use 5/8 chip stone. We use 3/8-inch stone because it compacts more tightly. Chip stone also drains, so water moves away from the pool instead of sitting under it.
Step 6: How Does the Shell Get Into Your Yard?
On delivery day, the shell arrives by truck, and the crew lowers it into the hole.
Not every fiberglass pool needs a crane. We bring in a crane only when access is narrow, and the only path to the backyard runs over the house. Crane service is not in our price, so we check access in step 1 and tell you early.
Once the shell is in the hole, the crew checks level, adjusts the stone under the shell, and checks again. A shell set out of level stays out of level, so this step never gets rushed.
A fiberglass shell arrives on site and gets set in place.
Step 7: Plumbing, Equipment, and Power
Once the shell sits level, the plumbing crew works in that 2.5-foot gap, running lines from the skimmer, returns, and drains to the equipment pad.
We build every fiberglass pool with Jandy pool equipment from the pump to the controls. We use Jandy variable-speed pumps, either 2.7 or 3.8 horsepower. We program each pump to run most of the day slowly because variable-speed pumps use far less power and keep electric bills down.
Want warm water in April or cool water in August? The Jandy VersaTemp heat-and-chill unit is an option on fiberglass builds, and we install the 160,000 BTU model for about $6,000. It runs on 230-volt power and needs a 50-amp breaker; if your electrical panel can't handle that load, the panel upgrade is extra.
Next, a licensed electrician wires the pump, lights, and any heater, and bonds the pool to code. Drain safety matters here too, since federal law requires pool drain covers to meet an anti-entrapment standard. You can read the drain cover rules from the Consumer Product Safety Commission.
Step 8: Why Do We Backfill With Chip Stone Instead of Sand?
Backfill determines whether your pool will still sit level 20 years from now, yet almost nobody asks about it. Remember the Broken Arrow pool from the start of this guide? Here is what happened on that job.
A Broken Arrow homeowner hired us to replace the concrete deck around an older fiberglass pool. Another company had built that pool years before and backfilled it with sand.
When our crew pulled up the deck, the sand was not wet or thin. It was gone, and a large empty cavity sat where the fill should have been. Wet sand can turn almost liquid, and over time it had washed out from behind the shell.
The damage was easy to see, since one side of the shell had dropped 2 inches, and the concrete around the pool was sinking. We filled the cavity with chip stone before installing the new deck. Once a pool has moved like that, though, there is no real fix.
A fiberglass pool is only as strong as what is packed around it.
So why do so many builders use sand or the dirt they dug out? Sand is cheap and leftover dirt is free, while chip stone is neither.
Here is how the three common backfill choices behave when wet.
| Backfill | What Happens When It Gets Wet | Long-Term Risk |
|---|---|---|
| Chip stone | Drains and stays locked in place | Lowest risk of movement |
| Sand | Turns soft and can wash out | Empty gaps, settling, and sinking decks |
| Dug-out dirt | Keeps settling as water moves through it | Sinking decks and shifting walls |
Dug-out dirt fails because time and gravity have packed undisturbed ground. Once you dig it up, no crew can pack it back that tight, so it keeps settling for years.
Look at the quantities, too. Our fiberglass build takes 80 to 100 tons of 3/8 inch chip stone. Since a ton is 2,000 pounds, that is 160,000 to 200,000 pounds of stone locking your shell in place.
Our method has outside approval too, since Leisure Pools reviewed our chip stone backfill with us in a meeting and approved it.
When the work is done right, the payoff lasts a long time. A fiberglass shell set and backfilled in chip stone should last 50 years or more. The gelcoat surface wears, which is another reason the waterline always gets tile. Our chip stone backfill guide covers this in more depth.
Before you sign with anyone, ask every builder what goes under and around your shell. It is one of the 7 builder questions we suggest asking on every bid, ours included.
Step 9: Tile, Coping, and the Deck
We tile the waterline of every fiberglass pool we build, because that is where sun and pool chemicals hit hardest. Over time, the gelcoat in that band can fade and turn chalky. A band of tile covers it and gives a fiberglass pool a custom look.
You choose glass or porcelain tile and pick the color, and the tile is included in every fiberglass starting price. It also guards the edge against dog claws as pets climb in and out. Our waterline tile guide shows the options.
We avoid patching worn gelcoat because a patch never looks quite the same as the rest of the pool. We would rather protect that band from day one.
The coping caps the top edge of the shell, and the concrete decking goes in after that. The deck is sloped away from the pool so rain runs off into the yard instead of into the water. If you want more deck than your build includes, added concrete runs about $17 to $21 per square foot.
Step 10: Startup and Pool School
The crew fills the pool and balances the water once the deck and barrier are done, and the city does its final inspection. Then we walk you through running the pool, including the pump settings, the water tests, and what to do when a storm blows leaves in. You also keep the maintenance kit included with the pool.
You swim once the whole job is finished, not before. We hold off until the deck, barrier, and final inspection are complete. We do not leave until you understand your pool, and we also talk through winter care.
We strongly recommend closing a pool for the season instead of running it all winter on freeze protection. Our closing service starts at $350, and we close pools we did not build, too.
What Can Change Your Price or Timeline?
| Factor | How It Affects Your Build | How Jason Handles It |
|---|---|---|
| Buried rock | Adds removal cost and time | The one thing that can move your quoted price, shown to you first |
| Sewer or utility lines | A line may need to move before digging | Found at the design visit, priced before contract |
| Crane access | Tight yards may need a larger crane or a new plan | Checked at step 1 |
| Spring rain | Wet ground can pause digging and backfill | Crews wait for workable ground |
| Permit wait | One week to about four, by city | Silverado Rock files every permit |
What I Recommend
Don't shop the shell, shop the install. I've been building pools for 29 years, and the problems I see rarely start at the factory. They start in the yard, so ask what's going under the pool and what's going around it. If the answer is sand or the dirt they dug out, walk away.
I chip stone every fiberglass pool I build. It costs more, and my price runs higher because of it. I'd rather explain my price than explain why a pool settled. When your kids are grown and bringing their own kids over to swim, that pool should still sit level.
Tile the waterline, too. It stops fading and chalking right where the sun hits hardest, and it makes the pool look custom.
Be patient, too, because anyone promising a finished fiberglass pool in a week is skipping steps.
Frequently Asked Questions About Fiberglass Pool Installation
How long does it take to install a fiberglass pool?
At Silverado Rock, most fiberglass pools take 4 to 6 weeks to build, including shell delivery. Permits come first and take about 1 to 4 weeks, depending on your city, and we set the shell in a single day.
What goes under a fiberglass pool?
We set every fiberglass shell on a bed of 3/8 inch chip stone at least 4 inches deep. We level and compact the stone dry, and a relief pipe at the deep end lets a pump draw groundwater out from under the shell.
Why is sand backfill bad for a fiberglass pool?
Wet sand can turn almost liquid and wash out over time. That leaves empty gaps behind the shell; without support, the pool can settle, and the deck around it can sink. Chip stone drains water and stays in place around the shell.
Can a fiberglass pool pop out of the ground?
Yes, if groundwater builds up under it. A fiberglass shell is light, so water pressure from below can push it up. A chip stone base and a groundwater relief pipe help keep that pressure off the shell. Never drain a fiberglass pool without talking to your builder first.
When can you swim in a new fiberglass pool?
We hold off until the whole job is finished. That means the deck is poured, the safety barrier is in place, and the city signs off on the final inspection. Then we start up the pool and hand it over to your family.
Does a fiberglass pool need a fence in Tulsa?
Yes. Tulsa and surrounding cities require a safety barrier around a residential pool. National guidelines call for a barrier at least 48 inches tall, with gates that close and latch automatically. Your city's code sets the exact rules.
Does every fiberglass pool need a crane?
No, you only need a crane when access is narrow, and the only way into the backyard is over the house. We check access during the first site visit, and we bill crane service separately when a yard needs it.
Do you need a permit for a fiberglass pool in Tulsa?
Yes, Tulsa and surrounding cities require permits for inground pools. We coordinate the permit for you, and the permit fee is separate from our price. Oklahoma law also requires a free OKIE811 locate request before you start digging.
How long does a fiberglass pool last?
A fiberglass shell set and backfilled in chip stone should last 50 years or more. The gelcoat surface is the part that wears, and waterline tile protects the band where the sun and chemicals hit hardest.
How much does fiberglass pool installation cost in Tulsa?
At Silverado Rock, fiberglass pools run from $45,000 to $90,000, and plunge pools start at $45,000, including waterline tile and Jandy equipment. Larger pools start higher based on size, and permits, hauling, and crane service are extra.
