We get a lot of questions about in-ground pools, which is understandable. Pools are a huge, permanent investment, and we’re the experts who want to make things as clear and easy for you as possible.

The most common question we get is about cost, so we’ve put together this handy guide to give you an idea of what to consider when shopping around for your dream pool.

Overall cost at a glance

  • Vinyl pool: $35,000–$65,000 installation; $11,500 in maintenance over 10 years
  • Fiberglass pool: $45,000–$85,000 installation; $3,760 in maintenance over 10 years
  • Concrete pool: $50,000–$100,000 installation; $27,400 in maintenance over 10 years

Breaking it down

Let’s take a closer look at what contributes to the overall cost of each type.

Vinyl liner pool installation costs

The least expensive of in-ground pools, vinyl liner pools consist of a custom vinyl sheeting that covers the walls and floor of the pool, which are usually compacted sand or similar material. A typical vinyl liner pool costs $35,000–$65,000 to install. The following options will affect your overall cost:

  • Size and shape of pool
  • Thickness of liner
  • Type of steps, ladders, benches
  • Coping material
  • Patio size and material
  • Wall panel type
  • Water features
  • DIY versus professional installation
  • Landscaping
  • Region

It should be noted, however, that going base-model everything with a vinyl liner pool may leave you with what looks like a budget swimming hole. Vinyl pools can be gussied up, but then you’re approaching the cost of a fiberglass pool.

Maintenance costs

The low cost of a vinyl liner pool is mainly due to the vinyl liner itself; however, that liner will need to be replaced every 5–9 years. That replacement will run you about $4,500 per replacement when it’s all said and done.

Vinyl liner pools don’t use as much electricity as fiberglass and concrete pools—and they require fewer chemicals—but you’ll still have about $700 in routine maintenance costs per year. Between the routine maintenance and occasional vinyl liner replacement, the average yearly maintenance cost is about $1,150.

Fiberglass pool installation costs

The next step up from vinyl liner pools, fiberglass pools are prefabricated, single-unit structures stuck into a hole in the ground. While they’re more expensive than vinyl liner pools—costing $45,000–$85,000 on average—fiberglass pools have the fastest installation time. These options could affect the installation costs:

  • Size and shape
  • Coping material
  • Patio size and material
  • Gelcoat color
  • Water features
  • DIY versus professional installation
  • Landscaping
  • Region

Most fiberglass pools are a kind of package deal, so be sure to ask your pool installer for a breakdown of the cost of the package. Some base packages may exclude permit costs, delivery fees and water, which are not insignificant costs.

Maintenance costs

Fiberglass pools have low maintenance costs compared to vinyl liner and concrete pools; you can expect to pay about $376 per year in routine maintenance. You will not need to replace anything in the pool itself (it’s all one piece), and the gelcoat surface of the fiberglass prevents algae and other unwanted flora from taking hold, so you’ll need fewer chemicals and less maintenance to keep it clean.

Concrete pool installation costs

The most expensive and most involved in-ground pool installation is for concrete pools, which are made simply of a ton of concrete poured into a cast-in-place form, which is reinforced with steel rods. The overall cost for a concrete pool can be affected by these options:

  • Size and shape
  • Interior finish
  • Waterline tile
  • Coping material
  • Patio size and material
  • Water features
  • Landscaping
  • Region

Concrete pools are pretty straightforward for installation, so there’s not much room for unexpected costs. Concrete pools may cost more and take longer to build, but they are (literally) rock-solid and the most aesthetically pleasing.

Maintenance costs

There are, however, significant regular maintenance expenses with concrete pools. Algae love the porous concrete surface, so you’ll need more chemicals and longer pump cycles to keep them at bay. This process alone will run you about $1,150 per year in routine maintenance.

You should also get a professional to acid wash the concrete every 3–5 years. This deep clean process gets into the pores of the concrete to kill any algae and remove stains on the concrete. An acid wash will run you anywhere from $200 to $900 depending on pool size your location.

Finally, you will need to have the pool re-plastered every 8–12 years, and the tiling will need replaced by then as well. The re-plastering and re-tiling can cost $6,000–$10,000.
