Frequently Asked Questions

Everything you need to know about our pool kits.

Is this a DIY pool kit?
Yes. Our kits are designed for DIY installation, and you can also hire a local contractor. Each kit includes step-by-step guidance, plus access to our pool experts if you get stuck.
What’s included in the kit?
The full inground pool kit for your chosen size, including the pool structure (steel or polymer), liner, and core components needed to build the pool. You can also add upgrades like wall options, steps, lights, and water features.
What sizes do you sell?
We currently sell rectangular kits in 12’×24’, 14’×28’, 16’×32’, 16’×36’, 18’×36’, and 20’×40’. Other shapes are coming soon.
Steel vs polymer walls, what’s the difference?
Both are strong and built for inground use. Steel is a classic, budget-friendly option. Polymer is corrosion-resistant and a popular choice in saltwater or high-moisture environments.
Do you ship nationwide?
Yes. We ship across the U.S. Your order ships as a complete kit, and we’ll coordinate delivery details with you.
How long does delivery take?
Most kits ship in a few business days, then transit time varies by location. After checkout, we’ll confirm an estimated delivery window.
Can I customize my kit?
Yes. Choose your wall type, liner style, wall height, and add-ons like steps, lights, heating, water features, and maintenance extras.
What support do you offer during installation?
You get clear instructions, a checklist, and access to our pool experts for questions before and during the build.
