Why Dakota Pools?


Welcome to Dakota Pools! We are a renowned Long Island swimming pool company located in Ronkonkoma, NY. We love creating beautiful oases in our clients’ backyards through our custom pool design and patio installation services. You may be wondering, though, why you should consider a custom pool. Here are some reasons to consider.

  • Enjoy more family bonding time in your pool, as you can relax in floaties, practice handstands, and play games together.
  • Indulge in a relaxing yet healthier activity in the comfort of your backyard; swimming and relaxing in your pool is healthier than lying on the couch!
  • Add balance to your life if you’re looking for a new healthy activity to add to your daily or weekly routine.
  • Host family gatherings, neighborhood get-togethers, and couples afternoons poolside in your very own backyard! If you enjoy hosting events for family and friends, adding a pool to your property may be the perfect addition.
  • Create the perfect oasis where you can destress after a long day at work.
  • Provide a safe and fun space for your kids to play all summer long!
