Quick Answer
Above ground pool liner costs vary significantly based on pool size, liner thickness, and material quality. Basic overlap liners start around $100 for smaller pools, while heavy-duty beaded liners for large pools can cost $800 or more. Professional installation typically adds $200-$500 to your total cost.
First, Let's Diagnose Your Liner Needs
Before determining exact costs, you need to identify what type of replacement liner your pool requires. The three main factors affecting price are:
- Pool size and shape - Round pools are less expensive than oval pools of similar size
- Liner attachment method - Overlap, beaded, or unibead systems have different pricing
- Liner thickness - Measured in mil (20 mil, 25 mil, 28 mil, or 30 mil)
Measuring Your Pool for Accurate Pricing
To get accurate cost estimates, measure your pool's diameter (for round pools) or length and width (for oval pools). Also measure the wall height - typically 48", 52", or 54". These measurements determine the liner size you'll need to purchase.
Liner Cost Breakdown by Pool Size
Round Pool Liner Costs
- 12' Round: $100-$200 (20-25 mil thickness)
- 15' Round: $120-$250 (20-28 mil thickness)
- 18' Round: $150-$300 (20-30 mil thickness)
- 21' Round: $180-$350 (25-30 mil thickness)
- 24' Round: $220-$400 (25-30 mil thickness)
- 27' Round: $280-$500 (25-30 mil thickness)
- 30' Round: $350-$600 (28-30 mil thickness)
Oval Pool Liner Costs
- 12'x24' Oval: $200-$400
- 15'x30' Oval: $300-$500
- 16'x32' Oval: $350-$550
- 18'x33' Oval: $400-$650
- 20'x40' Oval: $500-$800
Liner Types and Their Cost Impact
Overlap Liners (Most Economical)
Overlap liners drape over the pool wall and are held in place with coping strips. These are typically the least expensive option, running $100-$400 depending on size. They're easier to install but may not look as finished as other options.
Beaded Liners (Mid-Range)
Beaded liners have a thick bead around the top that snaps into a receiver track. They cost 20-40% more than overlap liners but provide a cleaner appearance and easier replacement in the future.
Unibead Liners (Most Versatile)
Unibead liners can work as either overlap or beaded systems. They typically cost slightly more than standard beaded liners but offer installation flexibility.
Installation Cost Considerations
Professional Installation
Professional liner installation typically costs $200-$500 depending on your location and pool size. This includes:
- Draining the existing pool
- Removing the old liner
- Installing the new liner
- Basic refilling assistance
DIY Installation Savings
Installing the liner yourself can save $200-$500, but requires physical effort and careful attention to detail. You'll need basic tools and should plan for a full day of work. Consider professional installation if your pool has complex features or if you're uncomfortable with the process.
Additional Cost Factors
Liner Thickness Impact on Price
20 mil liners: Most economical but shorter lifespan (3-5 years). Good for budget-conscious replacements.
25 mil liners: Good balance of cost and durability (5-7 years). Most popular choice for homeowners.
28-30 mil liners: Premium thickness offering maximum durability (7-10 years). Higher upfront cost but better long-term value.
Pattern and Design Costs
Basic blue or blue wall/blue bottom patterns are least expensive. Tile patterns, stone looks, and designer prints typically add $50-$200 to the base cost.
Money-Saving Solutions
Timing Your Purchase
Pool liner prices are often lowest during fall and winter months when demand is reduced. Planning ahead can save 10-20% compared to emergency spring replacements.
Bulk Buying Considerations
If you have multiple pools or neighbors also need replacements, some suppliers offer discounts on multiple liner purchases.
When to Replace vs. Repair
Replace your liner when you notice:
- Multiple tears or patches
- Significant fading or brittleness
- Liner pulling away from walls
- Constant water loss despite patches
Safety Warning: Never attempt to repair a liner while the pool contains water and electrical equipment is connected. Always turn off power to pool equipment before beginning any liner work.
Long-Term Cost Planning
Factor in that thicker liners cost more upfront but last longer, making them more economical over time. A 30 mil liner costing $600 that lasts 10 years provides better value than a 20 mil liner costing $300 that needs replacement every 4 years.
