Average Cost to Replace an Inground Pool Liner

The average cost to replace an inground pool liner depends on pool size, liner material, labor costs, and the condition of the pool structure.

👉 What’s the average cost to replace an inground pool liner?

The answer varies depending on several factors, including liner material, pool size, condition of the pool structure, and installation costs. This article breaks down typical price ranges and clarifies what affects the final cost.

What Does Replacing an Inground Pool Liner Involve?

An inground pool liner is the waterproof barrier that helps retain water inside the pool structure, typically made from vinyl or reinforced vinyl. Over time, exposure to UV, chemicals, and physical wear can cause a liner to degrade.

Replacement generally involves:

• Removing the old liner
• Inspecting and repairing the pool walls/floor if necessary
• Installing a new liner
• Adjusting and sealing edges
• Refilling the pool

Because of these steps, the total cost includes materials, labor, and any required repairs.

Average Cost Estimates by Pool Size

Here are typical cost ranges to replace an inground pool liner, including materials and professional installation:

• Actual prices depend on regional labor rates and liner quality.

Factors That Influence Replacement Cost

1. Type of Liner Material

The most common liner material is vinyl, available in standard and reinforced versions:

• Standard vinyl liner – most affordable
• Reinforced vinyl liner – longer lifespan, higher cost

Reinforced liners typically cost 15%–30% more but may last longer.

2. Pool Shape and Layout

Pool shape matters:

• Rectangular pools are easier to line
• Freeform or custom shapes require more cutting and seam work → higher cost

More seams increase material waste and labor.

3. Labor Costs

Labor costs vary by region. Urban and high-labor-cost areas usually have higher installation fees.

Professional installation ensures:

• Correct measurements
• Proper tension and fit
• Longer liner life

DIY replacement is possible but often risky, and may void warranties.

4. Structural Repairs

If the pool structure has cracks, rusted walls, or damaged track systems, additional repairs may be necessary:

✔ Wall repair

✔ Floor leveling

✔ Track replacement

These can add hundreds to thousands of dollars.

5. Underlayment / Cushion Layer

Adding an underlayment or pool cushion pad beneath the liner protects it from abrasion and extends service life. This adds material cost but can save money over time.

Typical Cost Breakdown

On average, the breakdown between materials and labor is roughly:

• Liner material: ~40% of total cost
• Installation labor: ~40%–50%
• Additional repairs & accessories: ~10%–20%

High-end liners or complicated pool geometry can shift these percentages.

Ways to Control Replacement Costs

Here are some practical ways pool owners can reduce total expenses:

✔ Choose a common liner pattern

Custom printed or specialty liners cost more.

✔ Schedule replacement off-season

Labor rates may be lower during less busy months.

✔ Prepare the pool base in advance

Removing debris and old adhesive reduces labor time for installers.

How Long Does a Pool Liner Last?

Typical lifespans:

• Standard vinyl liners: 5–10 years
• Reinforced liners: 10–15 years

Lifespan depends on:

• Chemical balance
• UV exposure
• Ground movement
• Installation quality

DIY vs Professional Installation

While it’s possible to install a replacement liner yourself, professional installation usually delivers:

✔ Accurate measurements

✔ A proper fit with minimal wrinkles

✔ Longer functional life

✔ Warranty compliance

DIY mistakes such as improper tension, curling edges, or poor sealing can shorten liner life.

Final Thoughts

So, what’s the average cost to replace an inground pool liner?

👉 For most pools, you can expect between approximately $1,200 and $4,000+, depending on size, liner quality, installation complexity, and regional labor costs.

Spending a bit more on quality materials and professional work often pays off with fewer future repairs and longer service life.
