Pool liner installation cost
The quote on a standard 16 × 32 pool is about $2,340 and it is an honest price for what it covers: the liner, and the labour to hang it. The day costs around $3,762, because replacing a liner means emptying the pool — 17,922 gallons to put back, the chemistry to turn them into pool water, and the first look anybody has had at the shell in a decade.

The quote is for the liner. The day is not.
A liner change empties the pool, which means it is also a refill, a chemistry restart, and the first look anybody has had at the shell in a decade.
Length times width, and nothing to argue about. Most inground pools and every lap pool.
Inside the walls, at the water line.
Inside the walls, at the widest point.
Vinyl-liner pools, which is most inground pools in America. A vinyl pool almost always has a hopper, and it is the hopper that makes the liner a bespoke product.
Water depth, not wall height.
At the bottom of the hopper.
The liner
The standard gauge and what most pools have had on them for decades. Thin enough that a careless installation shows, and thick enough that nothing in normal use troubles it.
The catalogue range. The print sits on the surface under a clear wear layer, and it is the print that fades first — long before the vinyl is finished.
A solid rolled edge that slides into a track at the top of the wall. The commonest by far.
The rest of the day
None of this is on a liner quote and all of it gets paid.
Floor wear is likely and a panel is possible. This is where a contingency stops being optional.
Ask the utility whether pool fills get a sewer credit — in many places they do, and it is most of the bill.
Off your water bill, including sewer if it is charged on a pool fill.
The refill needs the entire salt charge again — fresh water arrives with none of it.
One long day for two people.

The quote will say $2,340
That is the liner and the labour to fit it, and it is an honest price for what it covers. The other $1,422 is the pool being empty: $125 of water, $243 of chemistry to make that water into pool water, $140 of gaskets that come out with the old liner, and whatever the shell has been hiding.
The number that is not a price
$2,849 if the shell is sound, $4,509 if it is not
Nobody can see the floor or the wall panels until the old liner is out — and by then the pool is empty, the crew is there, and the work is happening. This is not a contingency in the usual sense. It is the part of the job that gets priced after it has started.
The $913 carried in the total above is an allowance for a pool 15 to 30 years old. It is what to have ready, not what anybody will invoice.
A liner is made to your pool, not bought off a shelf
There is no 16 by 32 in a warehouse. An inground liner is manufactured from a measure sheet of your own pool, and the part that makes it bespoke is the hopper and its compound angles. A liner made to a wrong measure sheet cannot be returned, because the measurements are the product.
What the paper says, and what the day costs
Both bars on the same scale.
| Gauge | The day | Years | A year | What it actually buys |
|---|---|---|---|---|
| 20 mil · yours | $3,762 | 10 | $376 | Nothing extra — the baseline |
| 27 mil | $4,229 | 12 | $352 · | Handling, and the dropped skimmer lid |
| 30 mil and heavier | $4,696 | 13 | $361 | Commercial toughness, and a stiffer hang |
Per year of service the gauges land within a few dollars of each other, because the price difference and the life difference very nearly cancel. Which means gauge is close to a free choice — pick it for how it handles and what it shrugs off, not as an economy.
What the day is made of
- 20 mil liner, a standard pattern
About 1,038 ft² of material, made to your pool's own measure sheet. The standard gauge and what most pools have had on them for decades. Thin enough that a careless installation shows, and thick enough that nothing in normal use troubles it.$1,090 - Draining, stripping and fitting
One long day for two people, and it does not stop halfway — an empty vinyl pool is held together by the water that is no longer in it.$1,250 - Refilling, 17,922 gallons
About 37 hours on a hose. Never on a liner quote, and paid every single time.$125 - Chemistry to restart the water
Stabiliser, calcium hardness, acid and alkalinity, plus the full salt charge — fresh water arrives with none. Fresh water is not pool water.$243 - Skimmer, return and drain gaskets
Replaced on every liner change, because they are only reachable now and a leaking one washes out the bedding under the new liner.$140
What it costs
National average. 20 mil liner on a 17,922 gallon pool, fitted, refilled and rebalanced, with an allowance for a shell 15 to 30 years old. Not included: a pump, a filter or a cover, and nothing above the coping.
$376 a year over the 10 a 20 mil liner usually lasts — the fairest way to compare gauges, and the comparison that shows they are nearly the same. The gallons come from the shape of the floor rather than an average depth, and if this is a salt pool the refill needs the whole salt charge again.
Worth knowing
- The quote will say about $2,340 — the liner and the labour to fit it. The day costs about $3,762, because a liner change empties the pool: $125 to put 17,922 gallons back in, $243 of chemistry to make that water into pool water, and $140 of gaskets that come out with it every single time. That is 61 per cent on top, and none of it is anybody being dishonest — it is simply not what a liner quote is for.
- Refilling takes about 37 hours on a garden hose at 8 gallons a minute — a day and a night with somebody watching it. Worth asking the water utility whether pool fills get a sewer credit, because in many places they do and it is most of the bill.
- Then there is whatever is under the old liner, and this is the one figure here that is not a price. It is either nothing or it is a floor and a wall panel: $2,849 if the shell is sound, $4,509 if everything that can be wrong is. The $913 carried in the total above is an allowance weighted for a pool 15 to 30 years old — it is what to have ready, not what anybody will invoice.
- On a pool 15 to 30 years old, floor wear is likely and a panel is possible. This is where a contingency stops being optional. The floor and the panels cannot be inspected until the old liner is out, and by then the pool is empty and the work is happening — so this is not a contingency in the usual sense. It is a part of the job that is priced after it starts.
- A liner does not wear out. It ends its life through plasticiser loss and ultraviolet at the waterline, which make it brittle until it tears somewhere it was stretched. That is why gauge buys puncture resistance and installation tolerance rather than years — and why the things that genuinely extend a liner's life are water chemistry and a cover, both of which are free by comparison.
- Per year of service the gauges land within $24 of each other: 20 mil at $376, 27 mil at $352, 30 mil and heavier at $361. The price difference between them is real and the cost-per-year difference is close to nothing, so choose the gauge for how it handles and what it shrugs off, not as an economy.
- An inground liner is manufactured to your pool's own measurements — there is no 16 by 32 on a shelf — and the part that makes it bespoke is the hopper, with its compound angles. A liner made to a wrong measure sheet cannot be returned, because the measurements are the product. Have whoever is fitting it take the measurements, and if you are ordering it yourself, measure it twice on two different days.

The quote is honest. It is also not the day.
The short version
- $2,340 quoted, about $3,762 paid on a standard 16 × 32 pool.
- A liner change empties the pool, so the water and the chemistry restart are part of it whether or not anybody quotes them.
- Nobody can see the shell until the old liner is out — $2,849 if it is sound, $4,509 if it is not.
- Gauge is close to a free choice. Within a few dollars a year across all three.
A pool liner quote is for a liner. It covers the material and the labour to hang it, and for that scope it is usually a fair price fairly given.
The trouble is that it answers a narrower question than the one being asked. Because replacing a liner means emptying the pool — and a pool that has been emptied has to be filled again, the water that fills it is not pool water, and the shell that has been underneath the old liner for a decade is about to be visible for the first time.
None of that is on the quote. All of it gets paid.

The first look at the shell in a decade
This is the part that makes a liner replacement different from almost any other pool job, and it is structural rather than commercial: the pool is opened on the same day it is repaired.
Until the old liner comes out, nobody has seen the floor or the wall panels since the last one went in. Not the fitter, not you, not the person who quoted it. And by the time anybody can look, the pool is empty, the crew is on site, and the work is under way — which is the worst possible moment to be getting a second opinion.
| What can be under there | Typical | Why it matters |
|---|---|---|
| Skimmer, return and main drain gaskets · always | $140 | Replaced as a matter of course on every liner change, because they are only reachable now and a leaking one destroys the new liner's bedding. |
| Floor washouts and cove repair | $420 | The vermiculite or grout floor under the old liner gets scoured by leaks and by groundwater. Every hollow shows through the new liner as a dent, and telegraphs every year after that. |
| Corroded steel wall panels | $900 | Steel-walled pools rust from the back, where nobody can see, and a panel that has gone soft will not hold a liner bead. It is the find that turns a liner job into a bigger one. |
| Step, corner or light niche repair | $340 | Corners take the most stress from a liner pulling tight, and a moulded step that has separated from the wall has to be re-bedded before anything goes over it. |
How much of that to expect is mostly a question of age, and the honest way to hold it is as money set aside rather than as a line in a budget — because it will not be the average. It will be nothing, or it will be a floor and a panel.
| Pool age | If sound | If not | Set aside |
|---|---|---|---|
| Under 15 years | $2,849 | $4,509 | $415 |
| 15 to 30 years | $2,849 | $4,509 | $913 |
| Over 30 years | $2,849 | $4,509 | $1,660 |
The last column is an allowance, not a price. Nobody will ever be invoiced that number — it is what to have ready.
Thickness is sold as years and buys something else
Every liner is sold by its gauge in mils, and the implication is always the same: thicker lasts longer, so thicker is the sensible buy. It is worth knowing what actually ends a liner’s life before accepting that.
A liner does not wear out. Nothing abrades it — the water is not abrasive and neither are the swimmers. What finishes it is plasticiser loss: the additive that keeps vinyl flexible slowly migrates out, accelerated by sun and by aggressive water chemistry, until the vinyl is brittle. Then it tears, and it tears at the waterline, where the sun is strongest and the stretch is greatest.
Thickness does not do much about that. What it does is resist punctures, tolerate a rough floor, and survive being dragged into position on a cold morning — all real benefits, and none of them the one on the label.
| Gauge | The day | Published life | Per year | What it really buys |
|---|---|---|---|---|
| 20 mil | $3,762 | 7–13 yr | $376 | The baseline |
| 27 mil | $4,229 | 9–15 yr | $352 | Handling, and a dropped skimmer lid |
| 30 mil and heavier | $4,696 | 10–16 yr | $361 | Commercial toughness, and a stiffer hang in the cold |
The whole spread is a few dollars a year, because the extra cost and the extra life very nearly cancel. Note also that the published ranges overlap heavily — the difference between a well-run pool and a badly-run one is larger than the difference between any two gauges.
| What extends a liner's life | What is sold as extending it | |
|---|---|---|
| Water chemistry kept in balance | Substantially, and it is free | — |
| A cover, for the sun as much as the heat | Substantially, and it pays for itself elsewhere | — |
| Keeping chlorine off the waterline | Yes — never dose undiluted at the edge | — |
| Going from 20 to 27 mil | A little | Sold as the main lever |
| A premium pattern | Holds its look longer | Sold as lasting longer |
| The warranty | Pro-rated, covers seams | Sold as twenty years |

What goes wrong
01Budgeting the quote as the job
The quote covers the liner and the fitting. The day also includes $125 of water, $243 of chemistry and whatever is under the old liner — about 61 per cent on top.
Instead — Price the water off your own bill and the chemistry off the pool's volume, then add an allowance for the shell before agreeing a date.
02Buying gauge as though it bought years
Liners end through plasticiser loss and ultraviolet at the waterline, not through wear. Per year of service the gauges land within a few dollars of each other.
Instead — Choose a gauge for how it handles and what it shrugs off. Then spend the attention on chemistry and a cover, which are what actually extend it.
03Ordering your own liner off a size
There is no standard inground size. A liner is manufactured to a measure sheet of your own pool, and the hopper's compound angles are what make it bespoke. A wrong sheet is not returnable, because the measurements are the product.
Instead — Have the fitter measure, so the risk sits with the person who took the numbers. If you must do it yourself, measure twice on two different days.
04Ordering the wrong bead
The bead is what holds the liner to the wall, and the wrong profile simply will not engage. It is the classic failure of buying your own liner online.
Instead — Photograph the existing top edge before ordering. If nobody is sure, a uni-bead can be used either way, which is exactly why it exists.
05Scaling the refill off a guessed volume
The water and the chemistry both scale directly with gallons, and the average-depth formula runs high on a pool with a hopper — which is most vinyl pools.
Instead — Work the volume out from the shape of the floor. It changes the water bill, the salt and every dose after that.
06Forgetting the salt on a saltwater pool
Fresh water arrives with no salt whatsoever, so a refill means the entire charge again — not a top-up. On this pool it is a meaningful share of the chemistry line on its own.
Instead — Budget the full startup dose, and test the fill water before adding it rather than assuming it starts at zero.
07Planning it as a job that can pause
An empty vinyl pool is held in shape by water that is no longer in it, and in wet ground an empty shell can float. It is also the moment anything found has to be decided quickly.
Instead — Book it as a start-and-finish day, and agree beforehand what happens and at what rate if the floor or a panel needs work.
08Not asking about a sewer credit
Many utilities rebate the sewer portion of a pool fill, because the water does not go down the drain. Where it exists it is most of the water bill.
Instead — Ring the utility before the fill, not after. It is nearly always applied for rather than granted automatically.
On the day, while the pool is open
- Photograph the empty shell — the floor, the cove and every panel. It is the only record that will exist for the next decade.
- Have the gaskets replaced at the skimmer, the returns and the main drain. They are only reachable now.
- Check the main drain cover is a current compliant one while it is accessible.
- Look at the cove where the floor meets the wall, which is where the liner is most stressed and where washouts start.
- Ask about the light niche and its conduit seal if there is an underwater light.
- Note where the hopper's slopes meet the flat panel — it is the hardest part to measure and the first place a badly made liner pulls.
- Agree what happens about anything found, and at what rate, before the crew starts stripping.
- Start the fill the same day. The pool should not sit empty overnight if it can be helped.
- 01Work out what the pool actually holdsThe refill is a real line and it scales with the gallons. The average-depth formula runs high on a pool with a hopper, which is most vinyl pools.
- 02Get the liner quote, and understand what it coversThe liner and the labour to hang it. That is an honest price for an honest scope, and it is not the cost of the day.
- 03Price the water separatelyOff your own bill, per thousand gallons. Ask whether pool fills get a sewer credit — where they do, it is most of it.
- 04Add the chemistry restartFresh water has no stabiliser, usually little calcium hardness, and on a salt pool no salt at all. That last one is the whole charge again.
- 05Set aside what the shell might be hidingNobody can see the floor or the panels until the old liner is out. On an older pool this is not a contingency — it is part of the job, priced after it starts.
- 06Choose the gauge on handling, not on yearsPer year of service the gauges land within a few dollars of each other. Pick one for how it hangs and what it shrugs off.
- 07Let the fitter take the measurementsA liner is manufactured to a measure sheet and cannot be returned if the sheet was wrong. Whoever measures owns that risk — make sure it is somebody who has agreed to.
The water and every chemical in the restart scale directly with what the pool holds — and that is the figure people get wrong most often, because the average-depth formula runs about 17 per cent high on a pool with a hopper bottom, which is nearly every vinyl pool.
The number the refill scales by- Mil
- A thousandth of an inch, the unit liners are sold in. A 27 mil liner is 35 per cent thicker than a 20 — and lasts perhaps 20 per cent longer, because thickness is not what ends a liner's life.
- Plasticiser
- The additive that keeps vinyl flexible. It migrates out over years, especially in sun and in aggressive water, and when enough has gone the liner turns brittle and tears where it was stretched. This is how liners actually end.
- Bead
- The shaped top edge of the liner that locks it to the wall. Standard bead slides into a track, a J-hook folds over the wall, and a uni-bead can do either. Ordering the wrong one is the classic mistake of buying your own liner.
- Hopper
- The funnel-shaped deep end of a vinyl pool: four sloping walls converging on a small flat panel. It is what makes a liner a bespoke product, because those compound angles have to be cut to your pool's own measurements.
- Measure sheet
- The form of dimensions a liner is manufactured from. It is the product specification, which is why a liner made to a wrong one cannot be returned.
- Cove
- The angled fillet where the floor meets the wall. It supports the liner at its most stressed line, and a washed-out cove shows through the new liner as a permanent dip.
- Vermiculite floor
- The cementitious floor of most vinyl pools, troweled over the base. Water that gets behind a failing liner scours it, and every hollow telegraphs through the new one.
- Vacuum set
- Drawing the air out from behind the liner with a shop vacuum so it pulls tight into every corner before water goes in. It is most of the skill in fitting one.
- Hydrostatic uplift
- The upward pressure of groundwater on an empty pool. It is why an empty vinyl pool is not a stable thing to leave, and why a liner change is a job that starts and finishes.
- Sewer credit
- A rebate some water utilities give on a pool fill, since the water goes into the pool rather than the sewer. Where it exists it is most of the water bill, and it is usually applied for rather than given.
- Wear layer
- The clear vinyl over the printed pattern. The print fades from underneath it long before the liner itself is finished, which is why an old liner can look tired while being structurally fine.
- Wall panel
- The steel or polymer sheet forming the side of a vinyl pool. Steel panels corrode from the back where nobody can see, and a soft one will not hold a liner bead.
Common questions
- How much does it cost to replace a pool liner?
- For a standard 16 × 32 ft inground pool, the quote is about $2,340 — the liner and the labour to fit it. The day costs around $3,762, because replacing a liner means emptying the pool: $125 to refill 17,922 gallons, $243 of chemistry to turn that water back into pool water, $140 of gaskets that come out with the old liner, and an allowance for whatever the shell has been hiding.
- Why is my liner quote lower than the total here?
- Because a liner quote is for a liner, and it is an honest price for that. It does not include the water, because the fitter does not sell water; nor the chemistry, because that is your pool's business; nor the repairs under the old liner, because nobody can see them yet. None of that is anybody being evasive. It is simply that the quote answers a narrower question than the one you are actually asking.
- Is a thicker pool liner worth it?
- For handling and puncture resistance, often yes. As an economy, almost never. A liner does not wear out — it ends its life through plasticiser loss and ultraviolet at the waterline, which make it brittle until it tears where it was stretched. Thickness barely touches that. On this pool the gauges work out at $376 a year for 20 mil, $352 a year for 27 mil, $361 a year for 30 mil and heavier — within a few dollars of each other, with 27 mil marginally ahead. Choose it for how it hangs on a cold morning, not to save money.
- How long does a pool liner last?
- 7 to 13 years for 20 mil, 9 to 15 years for 27 mil, 10 to 16 years for 30 mil and heavier — but the spread inside each of those ranges is bigger than the difference between them, and it is set by water chemistry and sun rather than by thickness. Aggressive water and an uncovered pool in strong sun will finish a 30 mil liner before a well-run covered pool finishes a 20.
- How much water does it take to refill a pool?
- This one holds 17,922 gallons, which is about $125 on mains water at $7 per thousand and roughly 37 hours on a garden hose. If a well cannot supply that and the water comes by tanker, it is about $1,344 instead — which turns it from a footnote into the second largest line of the job.
- What is found under an old pool liner?
- skimmer, return and main drain gaskets, floor washouts and cove repair, corroded steel wall panels, step, corner or light niche repair. The gaskets are replaced every time because they are only reachable now. The rest is genuinely unknown until the liner is out — and by then the pool is empty and the crew is there. Range on this pool: $2,849 if the shell is sound, $4,509 if everything that can be wrong is.
- Can I replace a pool liner myself?
- The material cost is $1,090 and you save the fitting labour, so the day comes to about $2,512 rather than $3,762. The water, the chemistry and whatever is underneath are identical either way. What stops most people is not the skill — it is that an empty vinyl pool is held in shape by water that is no longer in it, and in wet ground an empty shell can float. This is a job that starts and finishes in a day, not one that pauses for a weekend.
- How long does a pool liner replacement take?
- One working day for the liner itself, plus the refill. Drain, strip the old one, prepare the floor and cove, hang and vacuum-set the new one, then start the water. The refill is the long part — about 37 hours on a hose — and the pool is not swimmable until the chemistry has been restarted and circulated, so plan on the better part of a week end to end.
- What size liner do I need?
- There is no standard size to order, and that surprises people. An inground liner is manufactured from a measure sheet of your own pool — the length, the width, the shallow depth, the deep depth, and the hopper's dimensions and angles. Those compound angles are what make it bespoke, and a liner made to a wrong sheet cannot be returned because the measurements are the product. Have the fitter measure it.
- What is a bead and does it matter?
- It is the shaped top edge that holds the liner to the wall, and it matters because the wrong one does not fit. Standard bead: a solid rolled edge that slides into a track at the top of the wall. J-hook: hooks over the top of the wall rather than into a track. Uni-bead or EZ-track: can be used either way — hooked over, or the bead torn off and slid into a track. If nobody is certain what the pool has, a uni-bead can be used either way, which is why it exists.
- How much does a new vinyl liner pool cost to build?
- A different question with a very different answer — a complete vinyl-liner pool, excavated, walled, plumbed and decked, runs well into five figures and is a construction project rather than a maintenance job. This page prices replacing the liner in a pool that already exists, which is what most people searching for liner costs actually need.
- Should I replace the liner or resurface the pool?
- They are not alternatives — they are what different pools need. A vinyl pool has a liner and gets a new one every decade or so. A gunite or concrete pool has a plastered shell and gets resurfaced. If your pool has a printed pattern and a soft feel underfoot, it is vinyl and this is your page.
