Inground pool lifespans will vary based on the materials used to make the pool. A concrete pool has no set expiration date, but you’ll need to resurface the concrete about every 10 years. For vinyl-lined pools, the liner will need replacement every 6 to 12 years, varying heavily on usage and how closely you monitor water chemistry.
Fiberglass pools are extremely durable, and it’s not uncommon for them to last 30 years or longer after installation.
Don’t forget that these are just estimates. Your pool might last longer or shorter based on how well you maintain your pool and even factors like the area you live in.

How Long Do Vinyl Pool Liners Last?
A vinyl pool liner lasts about 6 to 12 years, but it’s not impossible to extend that timeline to 15 years—or even more. What causes them to eventually fail? Over time, sun exposure can dry and crack your liner, especially close to the surface level. This, combined with long-term exposure to the chemicals in your pool’s water will age your liner.
Age isn’t the only indicator, though. Sometimes you’ll need to replace a liner sooner if other warning signs are present. Look for additional tell-tale signs like cracking, fading, wrinkling, and leaking.
Vinyl liners are designed to have some elasticity, so the biggest signal that you’ll need to replace your liner is that the natural stretch starts going away. To combat this, use a pool cover whenever possible to reduce sun exposure. You’ll also want to have your pool’s water chemistry regularly checked. If your pool’s pH dips too low, the acidic water could further deteriorate your liner.
What Is the Typical Lifespan of a Concrete Swimming Pool?
The actual concrete of your pool will last 50 years or more. The issue with concrete pools is that the surface will need refinishing closer to every 10 years. The costs associated with resurfacing a concrete pool (usually about $7,000 per 1,000 square feet) will add up over time, but in terms of longevity, concrete is hard to beat.
You’ll know it’s time to refinish your concrete pool when you notice discoloration or staining, cracks, or overall roughness. As pieces of concrete and plaster break off, the smooth surface will become rougher, and can even cut and scrape your family and friends when they go for a swim. The resurfacing process involves removing any loose plaster, prepping the concrete for new plaster, and then applying a new layer.
Preserving your concrete pool starts with regular cleaning and brushing the walls. Any chemical buildup should be removed to prevent corrosion.
How Long Do Fiberglass Pools Last?
Fiberglass pools usually last about 30 years and won’t require replacement or replastering like vinyl and concrete do. Fiberglass is an extremely durable material. Additionally, fiberglass isn’t porous like concrete, which reduces the risk of cracks forming. There’s also no liner or pool walls to replace, which further lowers the need for maintenance over time. You may choose to apply a gel coating to reinforce the pool, but this process only needs to be done every 15 years, if ever. If you notice blistering, discoloration, or cracking, you’ll need to apply a new gel coating.
To get the most out of your fiberglass pool, emphasize your water chemistry. Even though the surface of a fiberglass pool is non-porous and resistant to algae, making sure your pH and chlorine levels are consistently maintained will help prevent corrosion.
