New swimming pool costs can vary extensively but it really comes down to how much you want to invest. Although some pool companies are willing to use inferior products and cut corners at every construction phase to build the cheapest pool, you should plan on spending a minimum of $25,000 for a basic pool. If you want to add a spa to the pool the cost will increase a minimum of 10k-15k. Of course, the larger the pool gets, the more it will cost. There is no shortage of features that can be added to the pool as well as upgraded materials. Most of these items would be specific to your pool or spa so the cost is determined based on your backyard.Don’t be fooled by the new pool special for prices that seem too low. It’s just like a car ad, it never exists!
