Saltwater pool vs. chlorine pool cost

A saltwater pool costs $29,000 to $100,000 for inground or $3,000 to $8,000 for above-ground. In comparison, a traditional chlorine pool costs $25,000 to $100,000 for inground or $1,600 to $7,500 for above-ground. Saltwater pools cost more initially, but chlorine chemicals and regular testing are more costly.

Installation

An inground saltwater pool costs $29,000 to $100,000, depending on the size and materials. Concrete saltwater pools cost much more than vinyl or fiberglass. An above-ground saltwater pool costs $3,000 to $8,000 on average.

A standard chlorine inground pool costs $80 to $250 per square foot or $25,000 to $100,000 total, depending on the size. A standard above-ground pool costs $1,600 to $7,500 with installation.

Maintenance

A saltwater chlorine generator "cell" costs $600 to $1,000 to replace every 3 to 6 years. Adding pool salt a few times per year costs $10 to $20 per 40-pound bag, or $90 to $180 for an average 18,000-gallon pool. You need 200 pounds of salt per 10,000 gallons of water to reach the proper salt level.

In comparison, professional pool maintenance costs $80 to $150 per month for a chlorine pool, depending on the pool size and the results of the weekly water testing. Most chlorine pool owners spend $175 to $750 per year on chlorine tablets and other chemicals.

Electricity

When it comes to environmental impact, chlorine and saltwater pools weigh in about the same. A saltwater pool contains less chlorine, but it requires a little more electricity to keep it going since the salt-chlorine generator runs continuously.

The cost to run a pool pump alone is $30 to $150 per month or $360 to $1,800 per year, depending on local energy costs and the type of pump.

Water quality

Saltwater pools have lower chlorine levels and a softer, silkier water feel compared to traditional chlorine pools. This means they're gentler on skin and eyes and more suitable for people wearing contacts.

In addition to the higher potential for eye and skin irritation, traditional chlorine pools also have a distinct smell from the chemicals. Some may find this smell nostalgic, while others may find it harsh or unpleasant.

Danger

In general, saltwater is easier on your skin and eyes but harder on the pool's components. Chlorine is more irritating and requires more effort to maintain, but it isn't as likely to damage the metal or other materials in your pool.

Salt also does not require any special storage or safety precautions, while chlorine chemicals do. Pool owners must store chlorine in a cool, dry, ventilated space.

What is a saltwater pool?

A saltwater pool uses a salt chlorine generator (or chlorinator) to convert pool salt into chlorine to sanitize the pool, as opposed to adding chlorine straight into the water. Saltwater pools aren't nearly as salty as swimming in the ocean, and they're gentle on the skin and eyes.

Since they use more specialized equipment to convert salt to chlorine, they're more expensive up front. However, they have lower maintenance costs than chlorine pools and require far less testing.

What is a chlorine pool?

Chlorine pools are the most common, least expensive, and oldest modern pool type. It's what you're likely used to swimming in. You'll know it by the chlorine smell and the red, irritated eyes and dry skin you get after using it.

They rely on added chlorine, typically as a liquid, tablet, or granules, to sanitize the pool. They require weekly or biweekly testing and balancing of the chemicals, pH balance, and other cleaning solutions.

Saltwater vs. chlorine pool cost factors

No matter what kind of water-sanitizing method you choose, there are a few factors that will determine how much you'll spend on a pool:

• Material: Vinyl and fiberglass pools cost less than concrete, or gunite, but they aren't nearly as durable or long-lasting.

• Depth: Pools that are deeper than average are more expensive to build and require more water. Most pools are about 6 to 7 feet deep. If you plan to install a diving board, you will need a deep end that's at least 9 feet deep.

• Winterizing: Closing a pool costs $250 to $500 for inground pools to prevent damage during sub-freezing temperatures. Opening a pool costs about the same to restore it to normal function after the weather warms up again.

• Climate: Pools generally cost more in northern states than in warmer southern states where they are more prevalent. Additionally, factors such as a remote location or a steep terrain can also increase the overall cost of the pool installation.

• Add-ons: Adding features like a heater, lighting, or a waterfall can increase the overall cost. Adding a pool deck costs $25 to $50 per square foot installed on average.

FAQs about saltwater vs. chlorine pools

Are saltwater pools completely chlorine-free?

No, saltwater pools are not chlorine-free because they produce chlorine through a generator. However, the chlorine levels are much lower and more stable compared to traditional chlorine pools.

Are there any health risks for saltwater pools?

Saltwater pools carry minimal health risks. The salt used is odorless and poses a low risk of allergic reactions. Additionally, it leads to fewer chloramines, which in turn reduces eye irritation and the typical chlorine smell associated with traditional pools.

Can you be allergic to a saltwater pool?

While many individuals are allergic to chemical chlorine, allergies to salt or the chlorine saltwater pools generate are relatively rare.

How long does it take to build a pool?

The installation of an inground vinyl liner pool requires 2 to 3 weeks, whereas constructing a concrete inground pool takes 6 to 8 weeks.

The installation of an above-ground pool typically takes 1 to 3 days. However, if you choose to build a deck or fence around the pool simultaneously, the project timeline will be longer.

Getting estimates from pool installation companies

While searching for pool installers near you, be sure to follow these steps:

• Obtain at least three quotes from licensed and insured professionals.

• Review their past work on websites like HomeGuide and Google to assess their reputation and service quality.

• Be wary of choosing the company with the lowest estimate, which could indicate poor quality materials or workmanship.

• Get a written, itemized contract and warranty before starting any work.

• Avoid making big upfront payments. Instead, pay the final bill after they finish the project.

Questions to ask a pool installer

Asking the right questions can help you get the best value for your money and make sure you're hiring the best company for your needs and budget:

• Does this estimate include materials and labor?

• Can you provide references?

• Are you fully insured and licensed?

• Do you have experience installing saltwater pools?

• How long will the installation take?

• What does the warranty cover?

• What are the payment terms?

• How does maintenance differ between saltwater and chlorine pools?

• Are there any health benefits to using a saltwater pool?

• Do you offer any maintenance or opening and closing plans?

• Do you provide training on how to use the pool equipment on my own?

• Do you offer decking and fencing services?
