That’s a great question and honestly, hearing what people regret can be just as helpful (if not more) than hearing what went right.
If I could go back and change one thing, I’d make the shallow end a bit bigger. At the time, I thought we’d be swimming laps more often, so we went with a deeper overall layout. Turns out, most of the time we’re just standing around, relaxing, or tossing a ball around with the kids. The shallow space feels a little cramped when there are a few people in the pool. Would’ve been nice to have more room where you can stand comfortably.
Another thing, I didn’t think much about shade during the planning stage. Now that we’ve had the pool for a couple seasons, I wish I had worked a small pergola or shade sail into the original design. Midday sun can be brutal, and dragging umbrellas around gets old fast.
I’ll also say this: I skipped the tanning ledge, thinking it was just a visual thing. Now I’m seeing how useful it actually is. Friends with little kids use it all the time, and it’s also perfect for just lounging half-in, half-out of the water without committing to a full swim.
Every pool’s different, but those are the things that stood out for me. Definitely worth thinking about how you actually plan to use it day to day, that helped me more than any brochure.
