Before you get an estimate from an installation company, you might want to shop around for prices online and get an idea of inground pool costs and expenses. Maybe you’re in the early stages of thinking about getting an inground pool, and you have no idea how much they cost.
This guide will help break down all the costs associated with pool sizes, materials, maintenance, additional features, and more:
- Overall cost
- Cost by material
- Cost by size
- Indoor pool cost
- Semi-inground pool cost
- Salt water pool cost
- Cost of water features
- Other expenses
Inground Pool Cost: How Much Does It Cost?
Let’s start with a simple answer. The average inground pool costs around $50-125 per square foot. This price totals around $25,000-60,000 overall from A to Z. Since that’s the average range, most people can expect to pay around $37,000 for the pool, but that depends on many different factors.
This table will help break down the cost and provide a visual for you:
|Adding Waterfall Feature||+$3,000|
|Adding Hot Tub||+$6,000|
Keep in mind that these are estimates and rough figures, so the cost you can expect to pay will vary dramatically based on who you hire, how much of the work you do yourself, where you live, how large the pool is, the type of swimming pool, the pool builder you use, and much more. I’ll consider all of these factors as I break them down into more detail below.
Cost by Type of Pool
One of the first determining factors you’ll have to consider is your materials. The type of pool you decide to build will not only play into the price you pay, but will also impact how you maintain and use your swimming pool for years to come.
Some materials are easy to maintain and clean, while others require more effort and involvement. Also, some are affordable upfront, but the maintenance cost down the road quickly catches up to you. Let’s look at the options and some of the pros and cons associated with each.
Concrete Pools Cost
|Cost to maintain over 10 years||$27,000+|
As you can see, a concrete pool (also referred to as shotcrete or a gunite pool) is the most expensive option. In addition to costing the most upfront, concrete is the most expensive to maintain, but it also has the most design flexibility. It’s not as simple as replacing a liner or patching a crack when you have a concrete pool; the repairs are heavily involved and are associated with a high cost.
The average cost of building a 14 x 28 inground concrete pool is around $60,000, with the costs of running as low as $30,000 and as high as $200,000 or more for large pools with tons of features. Where you also run into severe expenses is the cost of maintaining these pools.
Depending on your luck, maintaining the pool over ten years could cost as much as $27,000 or more. These pools require many more chemicals, and most owners need to acid wash the pool interior every four years to remove mold and algae.
As you wash it, you’re compromising the pool’s structural integrity, which can lead to further problems and damage down the road. You may need to resurface it sooner, but most people have to replaster their concrete pool at least once every 10-15 years. Replastering can cost upwards of $12,000 or more.
The main advantage of a concrete pool is complete control over the design and the overall aesthetics of the pool. You can add plenty of features with concrete that you can’t accomplish with vinyl or fiberglass.
- Complete control over the shape and design
- Adding value to your home
- Difficult to maintain
- Expensive to maintain
- High risk
Fiberglass Pools Cost
|Cost to maintain over 10 years||$3,700 or less|
The first material is fiberglass. These are affordable, and the maintenance cost is relatively low over ten years. You can expect to pay around $17,000 for a 10 x 16 and up to $62,000 for an 18 x 30 pool. The cost of maintaining it is a little less than $4,000, and these pools last up to 25 years or longer.
There are many bonuses to fiberglass, with the largest and most obvious one being the cost to maintain. Every other pool material will cost upwards of $10,000 over 10 years to maintain, so fiberglass is likely the best option if you’re looking for something that isn’t going to take a lot of your time or money over the years.
Fiberglass pools also offer unique ways to cut back on costs because you can do some of the work yourself.
Many companies sell fiberglass pool installation kits that allow you to cut the price in half by doing some of the work yourself. Here’s a general breakdown of how that works.
|DIY||$14,000 – $32,000|
|Assisted (they dig, set, and fill)||$23,000 – $47,000|
|Standard Installation||$28,000 – $62,000|
|Turn-Key Installation||$48,000 – $80,000|
- Easiest pool material to maintain
- Smooth surface requires less chemicals to keep the proper pH level
- Installation is fast and affordable
- Few customization options

Vinyl Pools Cost
|Cost to maintain over 10 years||$13,000+|
The cost to build a pool using vinyl material varies from $22,000 to $50,000, and while this is one of the most affordable options, maintenance cost is where it shocks many people.
It’s much more costly and time-consuming to maintain a vinyl liner pool because of their liners. The liners crack and break, which causes them to need replacing about every decade.
When that happens, you’re looking at the expense of around $5,500 to replace it, so the average cost to maintain a vinyl liner pool across 10 years is as much as $13,000 or more. The advantage is that vinyl is also easy to clean, and it has a very smooth finish that makes the algae wipe right off. You also don’t need a lot of chemicals to maintain proper levels.
Installation is a bit involved with vinyl inground pools but nothing too extreme. You would need a professional to handle this job from beginning to end.
- Low startup cost
- Easy to clean and maintain
- Comes with a small number of design options
- Liner replacements
- High cost of maintaining over the years

Swimming Pool Cost Breakdown by Size
While the average inground pool is 14 x 28, you might want something larger or smaller. You might not have enough space for a pool of that size, and if you decide to get a concrete pool, you’ll have a lot more control over how you fit the pool into your yard.
That said, this chart will break down each size and the average costs associated with the size and materials used. Remember that these are rough estimates, and you should not take them as direct figures. Many factors will cause these prices to fluctuate.
Taking Your Inground Swimming Pool Indoors
You might plan to build an enclosure around your pool or try to take advantage of some existing space in your home. The average indoor pool cost is between $100,000 and $200,000. It doesn’t cost any more to build the pool, but the costs start to add up when you consider the structure you’ll need to build over the pool.
Consider ventilation, dehumidifier systems, plumbing, electrical, pool covers, and more. All of these expenses quickly add up. It also depends on the materials you choose and the size of the pool. Most people have smaller pools indoors, although some pool owners may choose to build a larger lap pool.
You can read a much more in-depth breakdown in my indoor pool cost guide.
Semi-Inground Pool Cost
Semi-inground pools typically require more work than a normal inground pool, so pool owners should expect to pay an additional $7,000-10,000. However, it all depends on the pool type. Gunite pools will cost more than a vinyl liner pool or other material typically used in above ground pools. Get a quote from your pool professional if you’re interested in building a semi-inground pool.
Converting to Saltwater
There are many benefits to a saltwater pool, and I’m seeing more and more homeowners convert to this or start using salt water instead of chlorine. You don’t have to deal with the smell; they’re easier to maintain and much more gentle on your skin.
The average cost to build an inground saltwater pool is around $35,000 for the pool and $2,000 to convert it to saltwater.
Maintenance is simple. All you need to do is replace the cell in the generator every few years, which is around $800. This is cheaper with a saltwater generator. The salt for the pool is around $100 each time you need to fill or drain the pool.

Building Additions to Your Inground Pool
The best part of building an inground pool is envisioning all of the great additions you can put on. Most homeowners imagine a beautiful rock waterfall with a slide built in and bright blue lights illuminating the pool at night.
While that sounds great, many costs add up quickly when you start tacking all these unnecessary additions onto the pool. This chart will break them down for you.
|Additional Feature||Cost to Build and Maintain|
|Hot Tub||$2,500 – $20,000 based on quality and features|
|Pool Lights||$500 – $2,500|
|Waterfalls and Water Features||$500 – $16,000 based on design|
|Diving Board||$250 – $850|
|Slides||$600 – $19,000 based on individual situation|
|Steps||$500 – $3,000 based on pool style and step design|
|Pool Deck||$3,500 – $25,000 based on the size of the deck and materials|
|Pool Heater||$500 – $11,000 plus installation costs|
|Pool Cover||$1,000 – $3,000 or more for motorized covers|
|Pool House||$300 or more per square foot|
It helps to have a vision in mind when designing and planning the pool you want. It’s much easier and cheaper to factor in these costs ahead of time rather than decide you want something added later on.
For example, many pool covers are automatically built into the design of the pool. It would be much more expensive to come back later on and change the design because you wish you’d chosen an automatic one. To find out more, check out my article on the cost of a pool cover!
Additional Costs and Expenses
There are many hidden and long-term costs that swimming pool owners don’t think about when building an inground pool. Here are some of them.
Landscaping: $3,000 – $5,000
Once your new pool is installed, your yard will look like a wasteland of dirt, rocks, and mud. It will take a while for you to get the appearance back up to your standards. You’ll have to pay for things like sod, drainage, trees, and not to mention all the costs associated with getting the land ready for the pool. Plan for around $5-12 per square foot to add trees, shrubs, and other landscaping.
Other Expenses and Long-Term Costs
- Increased property taxes (nice guide here)
- Permits: $1,000+ (read my full post on pool permits)
- Electrical: $2,000+ per year (including monthly electrical costs)
- Maintenance: $1,000+ per year (more on that below)
