How Much Does It Cost to Open a Swimming Pool in 2026?

Whether you DIY it or call in a pro, the cost to open a swimming pool can vary a lot. Professional pool opening services typically run between $200 and $500, depending on your location and pool size. If you’re doing it yourself, plan to spend $50 to $150 on chemicals and supplies to open a pool, depending on the water’s condition.

Here’s a full breakdown of what pool opening actually costs and what drives that number up or down.

What is the Average Cost to Open a Pool?

Professional pool opening services typically cost between $200 and $500, depending on where you live and the size of your pool. If you’re in a higher cost-of-living area or have a large pool, expect to land toward the top of that range.

Doing it yourself is significantly cheaper. Most pool owners spend $50 to $150 on chemicals and supplies for a standard opening. That covers your start-up chemicals, shock, and test strips. If you stocked up last season and still have supplies on hand, you might spend as little as $30 to $60 just to restock shock and a few chemicals.

Why Pool Size and Pool Surface Affect Your Cost

The size of your pool is one of the biggest factors in what you’ll pay to open it. Larger pools mean more work across the board. A pro has to remove a larger cover, reinstall more fixtures, prep a larger, more complex filter system, vacuum more surface area, and use more chemicals to bring everything into balance.

If you want a ballpark by pool type, above ground pools typically cost $175 to $250 to open professionally. In-ground pools run higher, usually $250 to $500. Concrete and gunite pools tend to sit at the top of that range ($300 to $500) because they require more labor to clean than fiberglass or vinyl pools.

What’s Included in a Professional Pool Opening?

A pro typically handles everything from start to finish. They’ll remove and store your winter cover, reinstall your return jets, ladders, and skimmer baskets, restart your pump and filter system, and brush and vacuum the pool. Most companies will also balance your water chemistry. Some include a water test in the price, while others charge extra for chemicals. Always ask what’s included before you book.

How Much Does It Cost in Chemicals to Open a Swimming Pool?

After a winter of sitting still, your pool water can become contaminated. This means you’ll need to add more chemicals than you normally would for maintenance.

The biggest chemical expense at opening is shock. Plan to use 2 pounds (0.9 kg) of chlorine shock per 10,000 gallons (37,854 liters) at a minimum. That’s a standard double-shock treatment. If you open to visible green algae, triple that amount to three pounds (1.4 kg) per 10,000 gallons. For a 20,000-gallon (75,708-liter) pool, that means at least 4 pounds (1.8 kg) of shock and more if the water is green.

If you’re not sure what kind of shock your pool needs, check out our guide on What’s the Best Shock for Your Pool.

Beyond shock, the chemicals you’ll need depend on your pool size, your water quality, and what was left in the water over winter. Here’s a general breakdown of what to budget for:

• Chlorine shock: $25 to $56 for 6 to 12 lbs. of shock
• Chlorine tablets: $80 to $130 for a 50 lb. bucket
• pH increaser or decreaser: $10 to $15
• Alkalinity increaser: $10 to $15
• Calcium hardness increaser: $10 to $15

You may not be using chlorine tablets in your water. If you’re using unstabilized chlorine, you’ll need to purchase a chlorine stabilizer. And if you have a salt water system, you’ll need to buy pool-grade salt instead of chlorine tablets. This also doesn’t include water treatment for stain and scale.

What’s the Most Expensive Part of Owning a Pool?

While you can expect to spend a few hundred dollars to open your pool, the highest long-term cost is the electricity needed to run it year-round.

Running a pool pump for at least 8 hours a day adds up fast. Pools typically add $65 to $100 per month to your electric bill. If you add a pool heater to the equation, that monthly cost can jump to $200 or more.

Beyond electricity, you’ll need to consider ongoing costs for chemicals, maintenance, and the occasional repair. Annual pool ownership typically costs $3,000 to $6,000 total when you factor in maintenance, minor repairs, electricity, and water.

How Much Will Your Electric Bill Increase With a Pool?

Most pool owners see their electric bills increase by $50 to $150 per month with efficient equipment. If you run a heater, that number can climb to $100-$300 per month.

Your local rate makes a big difference. Run your pump during off-peak hours (typically nighttime) to take advantage of lower utility rates. Some utility companies offer time-of-use pricing that can shave a meaningful amount off your monthly bill. But you’ll also need to run your pump during the hottest part of the day to prevent algae.

You can split that into non-consecutive blocks to work around peak-rate hours. If temperatures drop below 40°F (4°C) in winter, run your pump continuously to prevent freeze damage.

How Much Does It Cost to Fill a Pool with Water?

Filling a pool from scratch costs less than most people think if you use municipal water. City water costs roughly $4 to $10 per 1,000 gallons ($1 to $2.60 per 1,000 liters). For an average 17,000-gallon (64,352-liter) pool, that works out to about $68 to $170 total.

Ask your municipality about a sewer fee credit when filling your pool. Since the water stays in your backyard and doesn’t flow into the sewer system, many water companies will waive the wastewater portion of your bill. That can save you a noticeable chunk of money on a full pool fill.

A water delivery service is faster but costs significantly more: about $30 to $100 per 1,000 gallons ($8 to $26 per 1,000 liters). Filling that same 17,000-gallon pool with delivered water could run $500 to $1,700.

If you’re on well water, your fill is essentially free except for the electricity to run your pump, usually $25 to $75 for a full pool fill. But you’ll need to test your well water before adding it to the pool, since it often needs treatment for pH, metals, and sediment.

Key Takeaways

• DIY pool opening costs $50 to $150 for chemicals and supplies. Professional pool opening services run $200 to $500, depending on location and pool size.
• Electricity is the biggest long-term pool expense, adding $65 to $100 per month to your bill and more if you run a heater.
• Switching to a variable-speed pump can cut your electricity costs by 50 to 70 percent and typically pays for itself in one to two years.
• Filling a pool with municipal water costs $68 to $170 for an average 17,000-gallon pool. Delivered water costs $500 to $1,700 for the same volume.
• Where you live significantly affects your costs. Warmer climates save on winterization but pay more in annual electricity and chemical expenses.
• Run your pump during off-peak hours to take advantage of lower electricity rates and reduce your monthly utility bill.
