How much does pool liner replacement cost?
Typical
$4,500
Most pay $2,000–$7,500 per project
Replacing a vinyl pool liner costs $2,000 to $7,500 for most pools, with the typical inground job landing around $4,500 installed. Above-ground pools are cheaper — $2,000 to $5,000, and often under $1,000 if you DIY a simple round pool. The liner itself is only part of the bill: labor runs $1,000 to $3,500, and refilling the pool adds $60 to $1,200 depending on whether you use the hose or a water truck.

What affects the cost
Inground vs. above-ground
Above-ground pools use standard round or oval liners that drop in fast — $350–$1,600 for the liner plus a few hours of labor. Inground pools need a measured, often custom-cut liner fitted to steps, benches, and curves, which is why they run $3,000–$7,500 installed.
Pool size
Liners are effectively priced by surface area. A 12x24 inground pool might need a $1,000 liner; a 20x40 needs $2,000-plus in material alone, plus more hours of fitting, more water to refill, and more old liner to haul away.
Liner thickness (mil)
Standard liners are 20-mil; upgrading to 27–30-mil adds roughly $700–$1,000 but resists punctures and UV fading better and typically carries a longer warranty. For dog owners and rentals, the upgrade usually pays for itself.
Custom shape and features
Freeform curves, vinyl-covered steps, benches, and deep-end hoppers all require precise measurement and extra seaming. Every feature adds material and fitting time; a true custom-measured liner can add $1,000+ over a standard pattern.
Labor and prep
Inground labor runs $1,000–$3,500: draining, stripping the old liner, repairing the floor and wall base, resetting track and gaskets, and vacuum-fitting the new liner. Wall rust or a washed-out sand floor discovered mid-job adds to the bill.
Water to refill
The forgotten line item. Filling from your hose costs $60–$120 in water for a typical 20,000-gallon pool but takes days; trucked-in water costs $400–$1,200 and fills it in hours. Add $50–$150 in startup chemicals either way.
Installed vinyl liner replacement cost by pool type and size
| Pool type | Size | Installed cost |
|---|---|---|
| Above-ground (DIY) | 24 ft round | $350–$800 (liner only) |
| Above-ground (pro install) | 24 ft round | $1,400–$3,200 |
| Above-ground (pro install) | 18x33 ft oval | $2,000–$5,000 |
| Inground | 12x24 ft | $3,000–$4,500 |
| Inground | 16x32 ft | $3,500–$5,500 |
| Inground | 20x40 ft | $4,500–$7,500 |
| Thickness upgrade to 27–30 mil | Any size | +$700–$1,000 |
| Trucked-in refill water | 20,000 gal | $400–$1,200 |
Cost by region
High labor rates plus a compressed spring install window — everyone wants the liner in before Memorial Day — keep prices at the top of the national range. Freeze-thaw cycles also shorten liner life to the low end of 5–9 years.
The most competitive market: more vinyl pools, more installers, lower labor. The flip side is a longer swim season and stronger UV, so liners fade and wear faster than the calendar suggests.
Vinyl is the dominant inground pool type here, so installers are plentiful and pricing sits near the national average. Book in late winter — spring slots go fast and off-season quotes run lower.
Vinyl pools are rarer out West (gunite dominates), so fewer specialists mean higher quotes and longer waits. In drought-restricted areas, refill water can be both expensive and regulated — check local rules before draining.
Why inground liners cost two to three times more
An above-ground pool is a standardized product — a 24-foot round pool takes a 24-foot round liner, made by the thousands and sold for $350 to $1,600. Installation is a half-day job of draining, swapping, and smoothing, which is why pro-installed above-ground replacements land between $1,400 and $5,000 and handy owners routinely DIY them for under $1,000.
An inground vinyl pool is the opposite: the liner is measured — sometimes laser-measured — to the exact dimensions of your specific pool, including step locations, bench angles, and the slope of the deep-end hopper. It's cut and seamed to order, then vacuum-fitted so it sits wrinkle-free against every surface. That precision is what you're paying $3,000 to $7,500 for, and it's also why inground liner replacement is not a DIY job: a liner set crooked or stretched wrong fails early, and the manufacturer's warranty usually requires professional installation.
Mil thickness: where the durability money goes
Liner thickness is measured in mils (thousandths of an inch), and the standard residential liner is 20-mil. Upgrading to 27-, 28-, or 30-mil typically adds $700 to $1,000 to the job and buys real puncture resistance, better UV tolerance, and usually a longer pro-rated warranty.
Whether it's worth it depends on the pool's life. A 20-mil liner in a gentle, well-kept pool lasts 5 to 9 years; the thicker material stretches that toward 10 or more. If the pool sees dogs, kids with toys, overhanging branches, or renters, the upgrade is cheap insurance — spread over the liner's life, $1,000 extra is about $100 a year to significantly cut the odds of doing this whole project early. One caveat: thickness doesn't fix water chemistry. A 30-mil liner in a chronically over-chlorinated pool will still fade and brittle ahead of schedule.
The full bill: liner, labor, and the water nobody budgets
The quote for an inground replacement breaks into three chunks. Material: $700 to $2,500 for the measured liner, depending on size, thickness, and pattern. Labor: $1,000 to $3,500 to drain the pool, strip and haul the old liner, repair and smooth the floor base, reset the track, replace gaskets and faceplates on every fitting, and vacuum-set the new liner. Good installers replace the gaskets by default — reusing old ones behind a new liner is a leak waiting to happen.
Then there's the refill. A 20,000-gallon pool filled from the garden hose costs $60 to $120 on a municipal water bill and takes one to three days. A water truck does it in hours for $400 to $1,200 — worth it when the install window is tight or well water would arrive loaded with metals. Add $50 to $150 in startup chemicals to balance the fresh fill, and check whether your water utility offers a sewer-charge adjustment for pool fills; many do, and it can cut the water bill meaningfully.
Repair or replace: reading your liner's age
Not every problem means a new liner. A single tear under an inch can often be patched — $100 to $350 professionally, or a $20 wet-patch kit if it's accessible — and a liner that's slipped out of its track can sometimes be reset. Patching a liner in years two through five usually makes sense.
The replacement signals are cumulative: widespread fading and chalky texture (UV and chemical breakdown), wrinkles that keep returning (the vinyl has stretched), rust stains bleeding through from the wall behind, water loss you can't attribute to evaporation, or multiple patches already in place. A liner past year seven with any two of those is done — and continuing to run a leaking liner is the expensive choice, because escaping water erodes the sand or vermiculite base underneath, turning a $4,500 liner job into a liner-plus-floor-rebuild. When you get quotes, ask what floor and wall repair costs if they find damage after the old liner comes out; pros expect the question.
What this means for landlords
A vinyl-lined pool at a rental is a wearing asset on a 5-to-9-year clock, so treat the liner like a roof: know its age at purchase, reserve for it annually (roughly $500–$900 a year against a $4,500 replacement), and inspect it at every turnover. Renters are hard on liners — pool toys, dogs, and missed chemical maintenance all shorten the life — which makes the 27–30-mil upgrade close to automatic for rental pools, and makes a landlord-paid service contract (see our pool cleaning guide) the cheapest liner-life extender there is, since bad water chemistry is the number-one premature killer of vinyl.
There's a liability angle too: a failing liner isn't just cosmetic. Leaks undermine the pool base and can wash out surrounding soil, and a torn liner edge or exposed fitting is an injury claim at a property you own. For short-term rentals, plan the replacement for the off-season — the job takes one to two weeks door-to-door including the refill, and blocking peak-season weeks for it burns more money than the liner costs. A faded-but-sound liner can usually wait for November; a leaking one can't.
Ways to save on pool service
- Book the job for late fall or winter — installers discount off-season work, and spring slots command premium pricing.
- Get three quotes with identical mil thickness and warranty terms; inground liner bids commonly spread by $1,500 for the same pool.
- Fill from the hose instead of a water truck if you can wait a couple of days — it's often $500+ cheaper.
- Keep water chemistry balanced year-round; chronic over-chlorination is the top cause of liners dying years early.
- Patch small, accessible tears in a young liner ($100–$350) instead of replacing — but stop patching once the liner is past year seven.
Frequently asked questions
How much does an inground pool liner replacement cost?
Between $3,000 and $7,500 installed for most pools, with a typical job around $4,500. Size, mil thickness, custom features like steps and benches, and refill water drive where you land in the range.
How long does a pool liner last?
Inground vinyl liners last 5 to 9 years on average; above-ground liners run 6 to 10. Balanced water chemistry is the biggest life-extender — chemical abuse can halve those numbers.
Can I replace a pool liner myself?
Above-ground, yes — standard liners drop in and handy owners do it for the cost of the liner alone. Inground, no: the liner is custom-fitted under vacuum, mistakes cause early failure, and warranties typically require professional installation.
Is a thicker liner worth the extra cost?
Usually. Upgrading from 20-mil to 27–30-mil adds $700–$1,000, resists punctures and UV better, and extends life toward 10 years — an easy call for pools with dogs, kids, or renters.
How much does it cost to refill the pool after a liner replacement?
From your hose, $60–$120 in water for a typical 20,000-gallon pool over one to three days. Trucked-in water runs $400–$1,200 but fills in hours. Budget another $50–$150 for startup chemicals.
Should I patch my liner or replace it?
Patch small tears in a liner under five years old ($100–$350). Replace when you see widespread fading, recurring wrinkles, rust bleed-through, unexplained water loss, or a liner past year seven with multiple patches.
