For head-first diving, The Red Cross recommends a depth of no less than 9 feet.

Semi Inground Pool Cost

A semi-inground pool will typically cost under $10,000. Semi-inground pools are normally constructed from extruded aluminum or steel and are often priced between $6,800 and $8,500, making them more expensive than a traditional above-ground pool but costing about a third of the price of an inground pool of equal size. The installation is much faster than that for an inground pool and can often be constructed in 1 to 3 days.

Indoor Pool Cost

Indoor pools usually start at around $110,000 for a 12’ by 16’ vinyl and go up to $220,000 for a 16’ by 32’ concrete inground pool, or even higher for a larger pool with more features and elaborate customizations. Customized indoor pool prices range from $200 to $250 per square foot and factor in a perimeter of 4’ around the entire pool for the room the pool will reside in.

Vinyl $35,672 $121,968 $25,000 $182,640
Fiberglass $45,864 $121,968 $25,000 $192,832

Price of Inground Saltwater Pools

The average price of an inground saltwater pool is $35,000 for the swimming pool and another $1,100 to $2,200 for the salt water generator, bringing the entire cost to around $36,100 to $37,200. Saltwater pools typically don’t require any chemicals added, are easier to maintain, and don’t have an offensive chlorine smell.

For pool buyers who opt not to use traditional chemicals in their pool, a saltwater pool uses a special system that converts the salt in the water into chlorine, but the levels are much lower than in a chlorine pool, so it is easier on your eyes and skin.

Estimating Long-Term Salt Water Pool Costs

  • Replacing the cell in the generator every 3–6 years at the cost of $800 ($100 less than if you had a regular chlorinated pool).
  • Adding salt to run your saltwater pool – An average pool measuring 14 by 28 with a depth of 6.5 feet has a water volume of just under 20,000 gallons, and for that much water, you will need around 11 x 40-pound bags of salt, which should total just under $100.

Custom Inground Pool Prices

An inground pool can go up by $2,000 to $10,000 with custom features that add value and functionality to your pool, but they don’t necessarily need to be a part of the initial installation and are options that can be added on later to help spread out the entire cost of the pool.

Normally the water at that shallow end is warmer than it is in the rest of the pool.

Lap Pool Cost

An inground lap pool typically costs between $20,000 and $70,000 depending on the size and materials. Many pool buyers opt to build longer pools in order to do more laps.

Cost to Put in an Inground Pool with a Hot Tub

For an inground pool with a hot tub, you can expect to add $8,000 to $25,000 to the base price depending on the style of hot tub and how it’s integrated with the rest of the swimming pool. Pool contractors normally offer to include the hot tub with the inground pool as part of their estimate, with discounts for getting both done simultaneously. Hot tubs vary in price depending on the number of jets, quality of materials, and the number of people they seat.

  • Entry Level – $2,000 to $4,000
  • Medium Quality – $5,000 to $8,000
  • High End – $9,000 to $12,000

Inground Pool Lights

Inground pool lighting ranges from $700 to $1,800, with LED and fiberoptic technology that can often be controlled from your smartphone or tablet. While pool lighting can be added after installation, it is a lot more cost effective to have them installed while the pool is being built.

The cost for a horizontal slit waterfall starts around $200, while the price of a rock waterfall for a pool costs about $1,500 for a prefabricated imitation rock installation or up to $15,000 or more for a custom installation constructed with real rocks.

Common more expensive styles include wedding cake steps, end steps, end steps with benches, corner steps, corner steps with benches, full-width end steps, end steps with side benches, and roman steps.

Pool Deck Cost

The cost for a pool deck ranges between $2,800 and $23,200 depending on the number of sides the deck is installed on, the width of the deck, and the selected deck materials. Material options include wood, and engineered or composite wood, and each has cost and durability considerations which should make the right choice easy to make.

2 sides 184 SF 400 SF $4,600 – $10,000
4 sides 400 SF 928 SF $10,000 – $23,200

Inground Pool Heater Cost

An inground pool heater cost can range from $550 to over $10,000, with another $400 to $500 for installation. The difference in prices for inground pool heaters is primarily how much water you need to heat, and what the rise in temperature is from the average coldest temperature to the desired water temperature.

  • Electric tankless water heaters generally start between $500 and $600.
  • Larger and more powerful electric pool water heaters average between $1,500 and $3,500.
  • Similar gas-powered pool water heaters fall between $800 and $2,500.

On the high-end, you will see solar pool heaters or electric pump water heaters for anywhere from $2,500 to $10,000. These work in hotter climates and transfer the heat in the air to the water in the pool, and they do so very economically.

Pool Fence or Enclosure Costs

A pool fence installation costs between $600 and $4,400 or more depending on the size of the pool, fencing materials you select, and how far back from the edge of the pool the fence is installed. Gates with a self-closing latch for your pool fence average an additional $200 to $250 each including installation.

Pool Cover Cost

Installing a manual or automatic pool cover at the cost of $550 to $3,000 is excellent for safety, keeping in more of the heat in the water, and helping restrict more of the moisture from doing any damage to the structure of the home. A high-end motorized cover will cost $4,800 to $6,000 depending on the pool’s size.

Cost Considerations When Building a Swimming Pool

The average cost to build a swimming pool increases depending on the location, surrounding landscaping, and additional features like lighting, decking, enclosures, and more.

Built-In Pool Cost by Location

The cost for built-in pools or inground pools will vary because of location in two respects–local location and geographic location. Built-in pool costs will increase if:

  • If your home is located in a northern state, you’ll pay 20% more, versus in a southern state such as Texas or Florida you’ll usually pay less.
  • Access to the pool installation site is difficult.
  • Various states and large cities have different labor costs that affect price. Nebraska and South Dakota have the lowest labor costs, and Hawaii has the highest.
  • Your home is more than 50 miles away from your pool company – it could add $50 to and from your property per day overage for transportation.
  • The site of your future pool in on a steep hill – this slows down daily productivity and could add thousands of dollars if the job takes longer.
  • There are lots of rocks to be excavated in the site.

Backyard Pool Landscaping Prices

Landscaping costs $3,000 to $5,000 on average for a new installation or around $4 to $12 per square foot to add plants, trees, and shrubs around your new pool. Three of the more common styles of landscaping design for built-in pools are tropical, modern, and desert. Here are average prices if you are starting with a bare-bones yard, or you want to add features to the backyard to complement the pool area:

  • Sod installation costs $0.90 – $1.80 per square foot and will help regrow your grass.

Additional Costs for Installing a Pool

On top of the cost to put in a pool, other prices include pool covers, building permits, electrician fees, increased insurance, and more.

  • Inground pools can cause your home’s value to go up, thus increasing your property taxes.
  • A pool increases the chances of someone getting hurt on your property which directly increases the cost of your homeowner’s insurance.

Electrician Cost for Inground Pool

The electrical work to bring power to your pool for the pump and filter costs around $2,200. Also, if there is a water heater being installed and there is insufficient capacity at the breaker panel, you may need to upgrade to a 300amp, as well as change the meter base, for about $6,000.
