Swimming pools are a commodity, and builder-owners realize that they add value to a home. One of the most popular options out there is semi-inground pools, and they highly sought after. With all of the appeal and popularity semi-inground pools boast, just how much do they cost?

Semi inground pools cost between $7,000 to $25,000. Many builders or owners spend closer to $13,000 and $16,000 on semi-inground pools but the larger ones can cost as high as $30,000. The price depends on the size, as well as the liner and the contractor that you choose to hire.

Semi-inground pools are much more expensive than above-ground pools, which typically cost $2,000-$7,000. Let’s take a close look at the costs of installing a semi-inground pool.

What Is a Semi Inground Pool?

A semi-inground pool is a swimming pool that combines the design of an above ground pool and an inground pool. There is a pool wall that is reminiscent of a standard retaining wall that makes up the semi-inground part of the name.

Some semi-inground pools can be fully submerged underground, but others cannot. The benefit to semi-inground pools is that they actually add value to a home, unlike above ground pools.

Because there are more structural elements to a semi-inground pool, regular maintenance is required to keep it safe and functional.

How Much Does a Semi Inground Pool Cost?

You can spend between $7,000 and $25,000 on a semi-inground pool, including installation. It is most common for builder-owners to spend $13,000-$16,000 between the pool and the labor.

Compared to inground pools that cost between $20,000 and $200,000, semi-inground pools are a steal. Semi-inground pools are effectively a mid-range pool option sandwiched between above ground and inground pools.

Type Of PoolCost
Above Ground$2,000-$7,000
Swim Spa$7,000-$30,000

The closest pool in cost to a semi-inground pool is a swim spa, but a semi-inground pool is often larger. Inground pools are quite expensive, so if you have your mind set on saving money, choose semi-inground over above ground.

Above ground pools do nothing to add value to a home, and the buyer may not want it left behind. A semi-inground pool, however, can sometimes add 50% of its value in value to the home when selling like a swim spa.

Cost To Install Semi-Inground Pool

As you probably noticed, the cost of a semi-inground pool spans a wide range. That is because of the wide range of cost factors, pool sizes, and bonus features that semi-inground pools offer.

If you know which cost factors to look out for, you can save and get the most for your money.

Semi Inground Pool Liner

This cost factor is optional, and not all builder owners choose to spend the extra money. A pool liner is made of vinyl and covers the floor and walls of the pool. Not only do pool liners make the water look more inviting, but they also keep algae out your pool.

A vinyl pool liner costs between $5 and $20 per square foot. Many semi-inground pools measure between 288 square feet, and 800 square feet.

Semi-Inground Pool SizeCost For Vinyl Liner
288 square feet$1,440-$5,760
400 square feet$2,000-$8,000
800 square feet$4,000-$16,000

Labor Costs Semi Inground Pool

As with any home addition, labor makes up the lions share of the total cost. Anytime that you have to hire out, you are at the mercy of someone else’s hourly rate and timeline. However, it is well worth it when your semi-inground pool is professionally installed.

Labor can span between $2,500 and $8,000 for semi-inground pool installation. How much your labor bill comes out to be varies depending on pool size and how many workers were there. It generally takes between 2 and 5 days to install a semi-inground pool.

One major labor cost that may come up depending on the pool you get is excavation. Excavation will likely be required for the part of the pool that is inground. When all is said and done, excavation can cost roughly $500-$4,000, or even more if there are rough conditions.

Semi Inground Pool Cover Cost

The pool cover is an expense that is easy to forget, but it is less easy on the wallet. Pool covers vary in size, and that is what determines their cost. Generally, semi-inground pool covers range between $120 and $400.

Blue Wave and GLI are great options for semi-inground pool covers. You should only use a pool cover for a maximum of 7 years before you replace it.

Other Factors that Influence Cost

Although the cost of labor and the type of material will significantly affect how much your semi inground pool costs, there are additional factors that can raise or lower your final cost. These include, but are not limited to:

  • The size of the pool. As you might expect, the bigger your pool, the more expensive it will be. Small pools are relatively affordable, as they are commonly made of less expensive materials and require less labor to install.
  • Ground preparation. Your contractor may have to grade or slope your property before the semi inground pool can be installed, which will raise the overall price.
  • Soil condition. If your property has rocky soil, this can also result in increased costs.
  • Pool permit. Depending on where you live, you may need to secure a permit to install a semi inground pool on your property. Don’t forget to include this in your cost calculations, as permits can sometimes be expensive.
  • The pool’s location. If the pool site is not easily accessible, expensive equipment may be required for the installation. With this in mind, the general rule of thumb is that the more challenging it is to install your semi inground pool, the higher the cost.
  • Increased homeowners insurance. A pool increases the possibility of someone getting injured on your property, which may result in your homeowners insurance going up in price.

Cost To Close Semi Inground Pool

Depending on where you live, you may have to winterize and close your semi-inground pool early fall. Leaving your pool running and uncovered during cold weather, especially in winter, can damage the pool.

It costs $150-$250 on average to close a pool for the year. Closing a pool is not as simple as popping the cover on it and shutting off the filter. Generally, a pool pro will pump out excess water and only live a little bit in the pool.

From there, they backwash and shock the water. Before closing the pool, they make sure that the water lines have no water. Otherwise, they could freeze and possibly break during the winter. You’ll spend roughly the same when it warms up and it’s ready to reopen.

Cost FactorAverage Cost
Vinyl Pool Liner (optional)$1,440-$16,000
Installation Labor Cost$2,500-$8,000
Semi-Inground Pool Cover$120-$400
Pool Closing & Opening$150-$240

What Is The Average Monthly Cost Of a Pool?

Most people spend between $50 and $100 each month to run and maintain their pool. However, that is mostly for homeowners that choose to hire a service for monthly pool maintenance.

In fact, that is quite common, and consists of shocking the pool, skimming, vacuuming if necessary, and adding necessary chemicals. You can save some money by investing in bulk chlorine, shock, and water pH level test strips. Buying your own chemicals will cost you $450-$750 a year.

It is worth doing your own maintenance, because hiring a service can cost between as much as $1,200-$1,500 a year. However, it is still a wise idea to hire a service to open the pool, do the initial treatment, and close it as well.

Semi Inground Pool vs. Above Ground Pool

Semi-inground pools and above ground pools share certain characteristics, but they are ultimately different. Of course, semi-inground pools are roughly $5,000-$18,000 more expensive than above ground pools.

Above ground pools are unique in that many of them are modular and portable. That is essentially the reason why above ground pools add no value to a home. However, semi-inground pools are looked at more as additions, similar to a swim spa.

Semi-inground pools are not quite as valuable as inground pools, but they are significantly more valuable than above ground pools.

Summing It Up

It costs $7,000-$25,000 to install a semi-inground pool. Labor runs you $2,500-$8,000, and excavations can also increase the cost. You may want to choose to handle chemicals and maintenance yourself and save up to $800 or more.

Semi-inground pools cost $5,000-$18,000 more than above ground pools, but they are worth the investment. They can add as much as 50% of the value of the pool to the value of the house when you sell it.

Try to do as much pool maintenance yourself as you can to save money. Consider a saltwater pool to save big on chemical costs, and the $150-$240 for opening and close each year won’t seem so bad.
