Most people picture a fiberglass pool going in over a weekend. A truck pulls up. A crane swings the shell into a hole. The kids swim by Friday.
That is not how it works in Tulsa. And the pools built in a hurry are often the ones Jason gets called back to fix.
This guide walks through every step of fiberglass pool installation the way Silverado Rock does it. You will see what happens at each stage, who does the work, and what you need to do. You will also learn why the stone under your pool matters more than the shell itself.
Later, you will hear about a Broken Arrow pool where the fill behind the walls vanished. 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. That count includes shell delivery. Permits come first and take about one to four weeks, depending on your city.
Here is the belief most buyers bring to the first meeting. Fiberglass is the fastest pool to build. Almost every national website says so.
The reality is different. The shell sets in a single day. But setting the shell is one of ten steps. The base, plumbing, backfill, tile, and deck all take real time. Rush any of them, and you pay for it later.
Here is how the three pool types compare at Silverado Rock.
| 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 |
Yes, you read that right. A vinyl liner pool from Silverado Rock is often faster than fiberglass. That surprises people. It also tells you that the "fiberglass in a week" pitch leaves steps out.
Bottom line? Plan your summer around 4 to 6 weeks, not 4 to 6 days. If you want to swim by Memorial Day, the calendar matters. Our guide to the best build season shows when to start.
The 10 Steps of Fiberglass Pool Installation at a Glance
Here is the whole job on one page.
| Step | What Happens | What You Do |
|---|---|---|
| 1. Design visit | Jason walks your yard and builds a 3D design | Tell him how your family wants to use the yard |
| 2. Permits and locates | Silverado Rock pulls permits and requests utility marks | Sign a few forms |
| 3. Shell order | Your EvoPool 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 groundwater plumbing go in | Nothing |
| 6. Shell set | The shell arrives, and a crane sets it level | 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 a 4,000 PSI deck | Choose tile and deck finish |
| 10. Startup | Water is balanced, and you get pool school | Learn your pool |
Step 1: What Happens at the First Site Visit?
Jason walks every yard himself. No salesperson comes first. He reads the slope, the soil, and where water runs after a storm. He looks for trees, fences, and power lines that could block a crane on delivery day.
Then he builds a 3D design in Pool Studio. Many builders still sketch on graph paper. A 3D render shows the pool, the deck, and extras you may add later. Think outdoor kitchen or fire pit. You see the finished yard before anyone digs.
This visit is also where Jason picks the skimmer spot. Here is the thing. Most Tulsa wind comes up from the Gulf. Jason has watched it for years. He says it blows from the southeast toward the northwest about 80 percent of the time. So he puts the skimmer on the northwest side whenever the house allows it. The wind pushes leaves to the skimmer instead of into a corner you net by hand.
Pro Tip: Ask every builder where the skimmer goes and why. If the answer is "wherever it fits," keep shopping.
Step 2: Permits and Utility Locates
Silverado Rock pulls every permit for you across the Tulsa metro. You sign a few forms. That is it. Permit time runs from about one week to four, depending on the city. Our Tulsa pool permits guide covers each city if you want the details.
Before anyone digs, Oklahoma law requires a locate request through the OKIE811 locate service. You must submit the request at least two business days before digging. Utility companies then mark buried gas, power, and cable lines with paint or flags. The service is free.
A bucket that hits a gas line stops the job cold. Marked lines keep everyone safe and the schedule on track.
Step 3: How Do You Pick the Right Fiberglass Shell?
Silverado Rock is an authorized EvoPools dealer. Every Evo shell is built with vinyl ester resin in every layer. That sentence sounds like a spec sheet. It is worth one minute of your time.
A fiberglass shell is layers of glass fiber held together by resin. The resin is the glue, and it decides how well the shell keeps water out.
Vinyl ester costs more than the polyester resin used in most typical shells. It resists water and chemicals better, which is why boat hulls are built with it. Some manufacturers use it only in the outer layers, where a buyer would see it on a cut sample. Evo uses it in every layer.
Why care in year 12 instead of year 1? Osmosis. Water works into the layers of a shell over the years and forms blisters under the surface. A shell built with marine-grade resin all the way through holds that off longer. EvoPools backs its shells with a lifetime structural warranty and a lifetime structural osmosis warranty.
Ask any builder which resin the shell uses, and whether the osmosis warranty is in writing. Vague answers tell you what you need to know.
Shell size is set at the factory, and shells travel by road, so your choices are limited by what a truck can haul. Inside that limit, you pick the model, size, depth, color, and features like benches or a tanning ledge. Then you order the shell, and we set a delivery date. That date anchors the schedule.
What does it cost?
At Silverado Rock, a fiberglass plunge pool starts at $45,000. Why not less? Two reasons. Jason tiles the waterline of every fiberglass pool, and he puts Jandy equipment on every fiberglass build. Both add cost up front. Neither one is optional on a Silverado Rock fiberglass build. That is the starting price for the smallest fiberglass pool we build, and larger models cost more. Our fiberglass pool cost guide breaks down what drives the final number.
Still deciding if fiberglass fits your yard at all? Read the honest pros and cons first.
Step 4: What Happens on Dig Day?
The excavator digs a hole a bit larger than the shell. Jason leaves about 2.5 feet of working room around the outside. The plumbing crew works in that gap. Later, it is where the chip stone goes.
Tulsa dirt fights back. Much of the metro sits on heavy clay. Clay holds water, swells when it gets wet, and shrinks when it dries out. That movement pushes on anything buried in it, including a pool. You can look up the soil on your own lot with the USDA soil survey. Our guide to Tulsa clay soil explains what it means for your build.
And it gets worse. Some yards hide rock. Your quoted price is fixed, except for one thing: buried rock. If the excavator hits a rock ledge no one could see from the surface, removing it adds cost. Jason shows you what the crew found before anything changes.
Pipes can hide too. On one current Tulsa-area fiberglass job, a sewer clean-out runs right through the pool footprint. A plumber has to move that line before anyone digs. It is far better to find that at the design visit than with the excavator bucket.
The dirt from the hole has to go somewhere. Some yards can use it to regrade low spots. Others need it hauled off. Ask about it before you sign.
Breaking ground on a Silverado Rock fiberglass pool build.
The hole is the easy part. 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. Jason explains it this way: "You buried a boat in your backyard."
A boat floats. So can a fiberglass pool if water builds up under it. That upward push is called hydrostatic pressure. Spring rain in Tulsa can raise groundwater fast. Jason points out that local gas stations keep their underground fuel tanks full in spring for the same reason. An empty tank in soaked ground can rise.
Here is how Silverado Rock builds the base to stop that from happening:
- A chip stone bed. A layer of 5/8 inch chip stone goes in the bottom of the hole. Jason sets the shell on that stone, not on sand or loose dirt.
- Dry compaction. The stone is leveled and compacted dry. The crew does not use water jetting to settle it.
- Groundwater plumbing. Plumbing goes in to pump groundwater out from around the pool. That relieves the pressure before it can lift or push on the shell.
Chip stone drains. Water moves through it and away from the pool instead of sitting under it.
Step 6: How Does the Shell Get Into Your Yard?
Delivery day is the day the neighbors come out to watch. The shell arrives on a truck. On most jobs, a crane lifts it over the house or the fence and lowers it into the hole. The crew checks level, adjusts the stone under the shell, and checks again.
A crane needs room to work. Overhead power lines, large trees, and narrow side yards all matter. That is why Jason checks access back in step 1. Finding a problem early costs a phone call. A problem found on delivery day can cost a second crane trip.
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 two-and-a-half-foot gap. Lines run from the skimmer, returns, and drains to the equipment pad.
Jason builds every fiberglass pool with Jandy pool equipment. The standard pump is a 2.7-horsepower Jandy variable-speed pump. Jason says most builders install 1 to 1.5 horsepower. The bigger pump moves about 155 gallons per minute. That is enough to run a waterfall and still keep every drop filtered. Jason programs the pump around peak and off-peak power hours so it runs slow when power costs the most.
The equipment sits on a 4-by-8-foot concrete pad. Many builders use the light pads made for air conditioner units. Those pads can sink over time. When a pad sinks, it can crack the pipes tied to it.
Want warm water in April or cool water in August? The Jandy VersaTemp heater/chiller unit is an option on fiberglass builds. Jason installs the 160,000 BTU model for about $6,000.
Next, a licensed electrician wires the pump, lights, and any heater, and bonds the pool to code. Drain safety matters here too. Drain covers sold in this country have to meet a federal anti-entrapment standard. You can read the drain cover rules from the Consumer Product Safety Commission.
Step 8: Why Does Silverado Rock Backfill With Chip Stone Instead of Sand?
Backfill is the least exciting step on this list. It also decides whether your pool still sits level in 20 years, and almost no buyer asks about it.
Remember the Broken Arrow pool from the start of this guide? Here is what happened.
A Broken Arrow homeowner called Jason's crew to add a spa and replace the concrete deck around an older fiberglass pool. Another company had built that pool years earlier and backfilled it with sand.
When the crew pulled up the deck, the sand was gone. Not wet. Not thin. Gone. An empty gap remained where the fill should have been. Over the years, water running through the ground had carried the sand off into cracks in the earth.
Fiberglass walls flex. They need solid support behind them. With nothing back there, the wall bowed out. That pulled the top of the pool down, and the whole pool settled. Jason's crew filled the gap with chip stone. But once a pool moves like that, 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? Cost and habit. Sand is cheap. Dirt is free. Chip stone is not. Jason estimates only about one in five builders around Tulsa uses chip stone.
Here is how the three common backfill choices behave.
| 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 away | Empty gaps, bowing walls, settling |
| Dug-out dirt | Settles as water moves through it | Sinking decks and shifting walls |
Why does dug-out dirt fail? Undisturbed ground has been packed by time and gravity. Once you dig it up, no crew can pack it back that tight. It keeps settling for years.
Now the simple math. A Silverado Rock fiberglass build takes 40 to 70 tons of chip stone, depending on the pool's size and shape. A ton is 2,000 pounds. That is 80,000 to 140,000 pounds of stone locking your shell in place.
Before you sign with anyone, ask one question: "What goes under and around my shell?" The answer tells you more than the brochure.
Step 9: Tile, Coping, and the Deck
Jason tiles the waterline of every fiberglass pool he builds. The waterline 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 makes a fiberglass pool look like custom gunite.
Few builders in the Tulsa area will tile a fiberglass pool. Jason's crew does it on every build.
The coping caps the shell's top edge. Then the concrete deck goes in. Silverado Rock pours a 4,000 PSI deck. Jason says 3,500 PSI is the common standard. A higher PSI number means a stronger slab. The deck is sloped away from the pool so rain runs off instead of into the water.
Step 10: Startup and Pool School
The crew fills the pool and balances the water. The city does the final inspection. Then Jason walks you through how to run the pool. You learn the pump settings, the water tests, and what to do when a storm blows leaves in.
He does not leave until you know your pool. He also talks about winter. Jason strongly recommends closing a pool for the season instead of running it all winter on freeze protection.
What Most People Get Wrong About Fiberglass Pool Installation
Most mistakes happen before the first shovel hits the dirt. Here are the four that cost Tulsa families the most.
They Compare Shell Prices Instead of Finished Pools
Two quotes can list the same shell and land $20,000 apart. The difference hides in the base, backfill, equipment, tile, and deck. A lower quote often means sand instead of stone or a smaller pump. Compare the full scope, line by line.
They Believe Fiberglass Installs in a Few Days
The shell sets in a day. The job does not. Plan for 4 to 6 weeks of build time after permits.
They Think Backfill Is Just Backfill
It is the difference between a pool that lasts and a pool that settles. Sand and dug-out dirt move. Chip stone stays.
They Skip the Hard Questions on Dig Day
Where does the dirt go? What happens if the crew hits rock? Where is the sewer line? Good builders answer these at the design visit. Vague answers now become change orders later.
What Can Change Your Price or Timeline?
Five things can move a fiberglass schedule or price.
| 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 |
Tulsa spring storms can roll in fast. If your dig date lands in a wet stretch, follow NWS Tulsa forecasts to see what is coming. A few days of waiting beats backfilling into mud.
What Jason Recommends
I'm Jason Cherry, owner of Silverado Rock in Tulsa. We're an authorized Evo Pools dealer and a PHTA member builder. We serve Tulsa, Broken Arrow, Jenks, Owasso, Bixby, and the surrounding towns. I build fiberglass, gunite, and vinyl liner pools.
Here's what I tell every family thinking about fiberglass.
Don't shop the shell. Shop the install. Most fiberglass shells come from good factories. What goes wrong happens in your yard. 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 I know my price runs higher because of it. I'd rather explain my price than explain why my product is built cheaper. When your grandkids are graduating high school, that pool should still sit level.
Tile the waterline. I do it on every fiberglass pool because it stops fading and chalking right where the sun hits hardest. It also makes the pool look custom.
And be patient with the calendar. A good fiberglass build takes 4 to 6 weeks. Anybody promising you a finished pool in a week is skipping something.
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 one to four weeks, depending on your city. The shell itself sets in a single day.
What goes under a fiberglass pool?
Silverado Rock sets every fiberglass shell on a bed of 5/8 inch chip stone. The stone is leveled and dry-compacted. Plumbing is also installed to pump groundwater away from the pool and relieve pressure under the shell.
Why is sand backfill bad for a fiberglass pool?
Sand turns soft when wet and can wash away over time. That leaves empty gaps behind the walls. Without support, fiberglass walls can bow, and the pool can settle. Chip stone drains and stays in place.
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 lift it. A chip stone base and groundwater plumbing help keep that pressure off the shell. Never drain a fiberglass pool without talking to your builder first.
Do you need a permit for a fiberglass pool in Tulsa?
Yes. Tulsa and nearby cities require permits for inground pools. Silverado Rock pulls every permit for you. Oklahoma law also requires a free OKIE811 utility locate request before you start digging.
Can you tile a fiberglass pool?
Yes. Silverado Rock tiles the waterline of every fiberglass pool it builds. The tile protects the gelcoat from fading and chalking at the waterline. It also gives the pool a custom gunite look.
How much does fiberglass pool installation cost in Tulsa?
At Silverado Rock, a fiberglass plunge pool starts at $45,000. That starting price includes waterline tile and Jandy equipment. Larger pools cost more based on the model, the site, and the features you choose.
